1 00:00:00,160 --> 00:00:02,680 Speaker 1: Guess what, Mango, what's that? Will do? You remember back 2 00:00:02,680 --> 00:00:04,720 Speaker 1: in two thousand and eight when Michael Phelps had that 3 00:00:04,840 --> 00:00:07,200 Speaker 1: daily diet that got so much attention because he was 4 00:00:07,240 --> 00:00:09,960 Speaker 1: eating these insane amounts of food. Yeah, he was eating 5 00:00:10,000 --> 00:00:12,800 Speaker 1: something like eight thousand calories a day. You try twelve 6 00:00:12,840 --> 00:00:15,280 Speaker 1: thousand cowers a day during his peak training, he need 7 00:00:15,320 --> 00:00:19,160 Speaker 1: a whole pizza, pound of pasta, three fried eggs, French toast, 8 00:00:19,239 --> 00:00:22,160 Speaker 1: multiple burgers, and it seemed like anything else he could 9 00:00:22,160 --> 00:00:25,080 Speaker 1: get his hands on, which seems so gross but also 10 00:00:25,280 --> 00:00:29,000 Speaker 1: kind of the best thing ever. And during those same Olympics, 11 00:00:29,040 --> 00:00:32,920 Speaker 1: Hussein Bolt reportedly ate forty seven thousand calories worth of 12 00:00:33,000 --> 00:00:37,600 Speaker 1: chicken McNuggets. Yeah, he was eating them with fries for breakfast, lunch, 13 00:00:37,840 --> 00:00:41,800 Speaker 1: and dinner. That seems at less great. Yeah, but wouldn't 14 00:00:41,840 --> 00:00:44,640 Speaker 1: sixteen year old Mango think of it's pretty incredible. So 15 00:00:44,680 --> 00:00:46,879 Speaker 1: I started thinking about this, and I know you've been 16 00:00:46,920 --> 00:00:48,839 Speaker 1: getting back into the tennis, and I've been running a 17 00:00:48,840 --> 00:00:51,559 Speaker 1: good bet these past few years. But I thought, if 18 00:00:51,560 --> 00:00:53,720 Speaker 1: I could just take this to the extreme, I may 19 00:00:53,720 --> 00:00:56,560 Speaker 1: be able to follow a similar diet. Like let's say 20 00:00:56,600 --> 00:00:58,840 Speaker 1: I'm running twenty miles a week, right, now, and I 21 00:00:58,920 --> 00:01:02,080 Speaker 1: just keep doubling up for the next five weeks, I'd 22 00:01:02,080 --> 00:01:04,759 Speaker 1: be running six hundred and forty miles a week by 23 00:01:04,800 --> 00:01:07,040 Speaker 1: the end of this. I'm so excited about this. Then 24 00:01:07,080 --> 00:01:09,959 Speaker 1: I could eat like twelve Chipotle burritos every day and 25 00:01:10,040 --> 00:01:12,600 Speaker 1: still have room for a half dozen Wendy Spicy Chicken 26 00:01:12,680 --> 00:01:15,440 Speaker 1: sandwiches and maybe even a couple of those naked chicken 27 00:01:15,520 --> 00:01:18,120 Speaker 1: choloopas after I run for the border. It's gonna be great. 28 00:01:18,800 --> 00:01:21,880 Speaker 1: But after our research for today's episodes, Science may have 29 00:01:21,959 --> 00:01:25,360 Speaker 1: crushed my dreams again. It turns out there's not quite 30 00:01:25,360 --> 00:01:28,080 Speaker 1: as strong of a connection between exercise and weight loss 31 00:01:28,120 --> 00:01:30,560 Speaker 1: as we once thought. So that's what we're gonna talk 32 00:01:30,600 --> 00:01:55,680 Speaker 1: about today. Stupid science. Yeah day their podcast listeners, Welcome 33 00:01:55,720 --> 00:01:58,080 Speaker 1: to Part Time Genius. I'm Will Pearson and as always 34 00:01:58,080 --> 00:02:00,560 Speaker 1: I'm joined by my good friend Man guesh Ticket and 35 00:02:00,600 --> 00:02:04,200 Speaker 1: today we're diving into the topic of exercise, its benefits, 36 00:02:04,240 --> 00:02:07,120 Speaker 1: it's limitations, whether it can actually help us shed some 37 00:02:07,280 --> 00:02:10,359 Speaker 1: unwanted pounds, and if it really makes us healthier people. 38 00:02:10,840 --> 00:02:13,200 Speaker 1: And fear not. We also have a couple of our patented, 39 00:02:13,280 --> 00:02:15,440 Speaker 1: ridiculous quizzes along the way. Who've we got on the 40 00:02:15,440 --> 00:02:18,119 Speaker 1: line today A mango. So we'll be talking to Herman Pontzer, 41 00:02:18,160 --> 00:02:20,960 Speaker 1: and anthropology professor at Hunter College in New York City. 42 00:02:21,320 --> 00:02:25,120 Speaker 1: He's responsible for some truly incredible research on exercise, and 43 00:02:25,160 --> 00:02:26,880 Speaker 1: he's gonna help us get to the bottom of just 44 00:02:26,919 --> 00:02:30,360 Speaker 1: how useful physical activity really is for burning calories. We're 45 00:02:30,400 --> 00:02:32,720 Speaker 1: also going to talk to a couple of personal trainers 46 00:02:32,760 --> 00:02:34,400 Speaker 1: and see if we can whip them into shape through 47 00:02:34,440 --> 00:02:38,160 Speaker 1: the power of our trivia. Right, So, before today's episode, 48 00:02:38,520 --> 00:02:40,800 Speaker 1: I would have told you that exercising is probably the 49 00:02:40,840 --> 00:02:43,360 Speaker 1: best way to lose weight, simply based on the conventional 50 00:02:43,400 --> 00:02:47,720 Speaker 1: wisdom of calories in, calories out. I mean that sounds sensible, right, Sure, 51 00:02:47,800 --> 00:02:50,200 Speaker 1: We're taken calories through what we eat and drink and 52 00:02:50,200 --> 00:02:53,080 Speaker 1: then burn them up through exercise. The more you exercise, 53 00:02:53,160 --> 00:02:55,760 Speaker 1: the more calories you burn, and the more weight you lose. 54 00:02:55,919 --> 00:02:58,560 Speaker 1: It just makes sense, it does. But there are actually 55 00:02:58,560 --> 00:03:00,720 Speaker 1: all these studies conducted over the last few years that 56 00:03:00,800 --> 00:03:04,360 Speaker 1: suggests exercise really isn't an effective way to lose excess weight. 57 00:03:04,800 --> 00:03:08,000 Speaker 1: For example, Dr Timothy Church at the Pennington Biomedical Research 58 00:03:08,040 --> 00:03:10,720 Speaker 1: Center at l s U. He held an experiment where 59 00:03:10,800 --> 00:03:14,240 Speaker 1: hundreds of overweight women were given strict workout regiments for 60 00:03:14,280 --> 00:03:17,320 Speaker 1: six months. The one group of them exercised a little 61 00:03:17,320 --> 00:03:19,760 Speaker 1: over an hour each week, another one for a little 62 00:03:19,760 --> 00:03:23,400 Speaker 1: over two hours, and another for over three hours. There 63 00:03:23,480 --> 00:03:25,560 Speaker 1: was also a fourth group that stuck to their typical 64 00:03:25,680 --> 00:03:29,320 Speaker 1: routine and didn't exercise at all. And against all logic 65 00:03:29,400 --> 00:03:31,799 Speaker 1: and fairness, there was no major difference in the weight 66 00:03:31,840 --> 00:03:34,280 Speaker 1: loss between the women who had exercised and the ones 67 00:03:34,320 --> 00:03:35,960 Speaker 1: who had And how pissed would you be if you 68 00:03:36,040 --> 00:03:38,720 Speaker 1: were that three hour group. In fact, some of the 69 00:03:38,760 --> 00:03:42,240 Speaker 1: women in the exercise groups actually gained weight, which doesn't 70 00:03:42,240 --> 00:03:44,960 Speaker 1: seem fair at all. I mean, they put in the work, 71 00:03:45,000 --> 00:03:47,480 Speaker 1: they deserve a reward. Well, it's funny you should say that, 72 00:03:47,520 --> 00:03:51,360 Speaker 1: because Church actually concluded that the rewards were the problem. 73 00:03:51,360 --> 00:03:54,360 Speaker 1: You know, exercise stimulates appetite, and many of the women 74 00:03:54,400 --> 00:03:58,200 Speaker 1: counteracted their work by over eating afterward. Church suggested that 75 00:03:58,240 --> 00:04:00,160 Speaker 1: it was justified in their minds. Is kind of a 76 00:04:00,240 --> 00:04:03,720 Speaker 1: self reward for all the energy that exerted through exercise. Yeah, 77 00:04:03,760 --> 00:04:05,480 Speaker 1: we hear that sort of thinking all the time, like 78 00:04:05,640 --> 00:04:08,480 Speaker 1: cheat days and junk food rewards for going to the gym. 79 00:04:08,560 --> 00:04:11,880 Speaker 1: But if we're canceling out the calories we burn. Then 80 00:04:11,880 --> 00:04:15,160 Speaker 1: we're probably imagining our workouts to be much more effective 81 00:04:15,160 --> 00:04:17,680 Speaker 1: than they really are. I mean, the Department of Health 82 00:04:17,680 --> 00:04:20,599 Speaker 1: and Human Services recommends people aim for at least thirty 83 00:04:20,600 --> 00:04:23,640 Speaker 1: minutes of physical activity every day, But at thirty minute 84 00:04:23,680 --> 00:04:26,960 Speaker 1: workout that only burns about two hundred calories, and the 85 00:04:27,040 --> 00:04:30,440 Speaker 1: average slice of pizza contains close to like three hundred calories. 86 00:04:30,720 --> 00:04:32,800 Speaker 1: So you can see how the math doesn't quite work. 87 00:04:32,960 --> 00:04:36,400 Speaker 1: It's really just not fair at all. But it isn't 88 00:04:36,400 --> 00:04:40,200 Speaker 1: just those powerful post workout indulgences that counteract calories burned 89 00:04:40,240 --> 00:04:43,360 Speaker 1: through exercise. You know, the things we consume in preparation 90 00:04:43,480 --> 00:04:46,480 Speaker 1: for or even during a workout can also take a toll, 91 00:04:46,680 --> 00:04:48,800 Speaker 1: which is a good point. I mean, those two hundred 92 00:04:48,800 --> 00:04:51,280 Speaker 1: calories you burned during your thirty minutes on the treadmill, 93 00:04:51,640 --> 00:04:54,000 Speaker 1: every single one goes right back into your body thanks 94 00:04:54,000 --> 00:04:56,560 Speaker 1: to that bottle of gatorade or that energy bar you 95 00:04:56,640 --> 00:04:59,159 Speaker 1: might have scarfed down while running right right, And the 96 00:04:59,200 --> 00:05:01,320 Speaker 1: same goes for the eagle or the oatmeal used to 97 00:05:01,360 --> 00:05:04,440 Speaker 1: carbo load before your workout. And we think the energy 98 00:05:04,480 --> 00:05:06,679 Speaker 1: from these meals is going to help us power through 99 00:05:06,839 --> 00:05:09,520 Speaker 1: and burn more calories at the gym, But it's actually 100 00:05:09,520 --> 00:05:11,880 Speaker 1: the calories from those pregame foods that are going to 101 00:05:11,920 --> 00:05:14,440 Speaker 1: get burned off first. And why is that Well, because 102 00:05:14,440 --> 00:05:17,240 Speaker 1: sugar from what you've just consumed will still be floating 103 00:05:17,279 --> 00:05:20,719 Speaker 1: freely in your bloodstream, and it takes muscle tissue much 104 00:05:20,800 --> 00:05:23,039 Speaker 1: less energy to take that sugar than it does to 105 00:05:23,080 --> 00:05:26,320 Speaker 1: burn off the existing fat stores. So your most recent 106 00:05:26,400 --> 00:05:29,080 Speaker 1: meal will always be the first to go during a workout. 107 00:05:29,279 --> 00:05:31,760 Speaker 1: But we can always just exercise a little longer, right, 108 00:05:31,800 --> 00:05:35,200 Speaker 1: I mean, once those preliminary calories are gone, our muscle 109 00:05:35,240 --> 00:05:38,080 Speaker 1: cells will start tipping away at storage fat for fuel. Well, 110 00:05:38,120 --> 00:05:41,000 Speaker 1: I mean yes and no. According to some breakthrough research 111 00:05:41,040 --> 00:05:43,280 Speaker 1: from Herman pons Er, there are a lot of assumptions 112 00:05:43,279 --> 00:05:46,880 Speaker 1: we've been making about human metabolism that they're not quite right. 113 00:05:47,000 --> 00:05:49,600 Speaker 1: So you know, it's true that a longer workout would 114 00:05:49,680 --> 00:05:53,200 Speaker 1: result in more calories burned and even some from storage fat. 115 00:05:53,839 --> 00:05:55,880 Speaker 1: But we know there's a limit to how many calories 116 00:05:55,920 --> 00:05:58,719 Speaker 1: your body will metabolize in any given day. So I'm 117 00:05:58,800 --> 00:06:01,359 Speaker 1: definitely intrigued. But before we get too far into this, 118 00:06:01,480 --> 00:06:05,280 Speaker 1: we should probably clarify the basics of metabolism. All right, 119 00:06:05,279 --> 00:06:08,839 Speaker 1: well I'll let you do that. Go for it, okay. 120 00:06:09,040 --> 00:06:13,200 Speaker 1: So metabolism is basically the sum of all the processes 121 00:06:13,240 --> 00:06:17,200 Speaker 1: that takes place in our bodies. We're talking digestion, respiration, 122 00:06:17,480 --> 00:06:20,760 Speaker 1: the production of cells, the movement of substances between cells, 123 00:06:20,880 --> 00:06:24,560 Speaker 1: you name it, and all these processes require energy, which 124 00:06:24,600 --> 00:06:27,960 Speaker 1: our bodies released from the calories we consume. So even 125 00:06:28,040 --> 00:06:31,520 Speaker 1: without exercise and other forms of physical activity, we still 126 00:06:31,680 --> 00:06:35,560 Speaker 1: burned through or metabolize a huge number of calories simply 127 00:06:35,600 --> 00:06:38,880 Speaker 1: by being alive. Yeah, exactly. So back to Herman Ponsers 128 00:06:38,920 --> 00:06:43,280 Speaker 1: World Shattering Research and February's issue of Scientific American, Herman 129 00:06:43,400 --> 00:06:46,000 Speaker 1: shared findings from his study of the Hadza tribe and 130 00:06:46,080 --> 00:06:49,560 Speaker 1: rule Tanzania. He and other researchers spent a whole month 131 00:06:49,640 --> 00:06:51,960 Speaker 1: living with the Hatsa, who were one of the last 132 00:06:52,000 --> 00:06:55,560 Speaker 1: traditional hunter gatherer cultures left on Earth. It was during 133 00:06:55,600 --> 00:06:58,279 Speaker 1: this time that Herman and his partners recorded measurements of 134 00:06:58,320 --> 00:07:01,880 Speaker 1: the daily energy expenditures of a couple dozen tribesmen and women. 135 00:07:02,600 --> 00:07:05,000 Speaker 1: So this allowed them to compare the daily calorie burn 136 00:07:05,040 --> 00:07:07,880 Speaker 1: of a society in which every member is highly active 137 00:07:07,960 --> 00:07:10,400 Speaker 1: to a Western society like our own and which members 138 00:07:10,400 --> 00:07:14,360 Speaker 1: are more you know, sedentary. Well, back up a second. 139 00:07:14,600 --> 00:07:18,280 Speaker 1: You said the researchers measured the hadzas daily energy expenditure. 140 00:07:18,560 --> 00:07:21,080 Speaker 1: But I'm wondering how they pull that off. Are you 141 00:07:21,120 --> 00:07:23,440 Speaker 1: really wondering that mango orre you just sensing there's an 142 00:07:23,440 --> 00:07:27,800 Speaker 1: opportunity here to talk about doubly labeled water? Of course 143 00:07:27,840 --> 00:07:31,320 Speaker 1: it is, you know, I love the d LW. Doubly 144 00:07:31,440 --> 00:07:34,600 Speaker 1: Labeled water is the special water in which the hydrogen 145 00:07:34,760 --> 00:07:38,760 Speaker 1: and oxygen molecules have been either partly or entirely replaced 146 00:07:38,800 --> 00:07:42,200 Speaker 1: with heavy isotopes that aren't usually found in the human body. 147 00:07:42,520 --> 00:07:46,360 Speaker 1: And it's safe to drink this stuff completely. They're stable isotopes, 148 00:07:46,400 --> 00:07:49,760 Speaker 1: so they're non radioactive. But here's what's great about them. 149 00:07:49,800 --> 00:07:53,360 Speaker 1: After somebody drinks d l W that's been enriched, researchers 150 00:07:53,360 --> 00:07:57,280 Speaker 1: suddenly have this tracking mechanism. Basically, by measuring the concentration 151 00:07:57,320 --> 00:08:01,200 Speaker 1: found in urine samples, researchers can determine person's daily rate 152 00:08:01,200 --> 00:08:04,640 Speaker 1: of carbon dioxide production. And since carbon dioxide is a 153 00:08:04,640 --> 00:08:08,640 Speaker 1: waste product of our bodies energy making processes, calculating how 154 00:08:08,720 --> 00:08:11,120 Speaker 1: much c O two someone produces in a day is 155 00:08:11,160 --> 00:08:14,120 Speaker 1: the best way to measure their energy expenditure. That is 156 00:08:14,160 --> 00:08:17,400 Speaker 1: pretty neat. Yeah, Doubly labeled water has become the gold 157 00:08:17,480 --> 00:08:20,760 Speaker 1: standard for measuring how much energy a person consumes. Like, 158 00:08:20,800 --> 00:08:23,920 Speaker 1: the margin of error is pretty small, and in fact, 159 00:08:24,000 --> 00:08:27,560 Speaker 1: the only downside is the cost. D LW is expensive, 160 00:08:27,960 --> 00:08:30,720 Speaker 1: like are we talking smart water expensive or like Fiji 161 00:08:30,720 --> 00:08:33,840 Speaker 1: water expensive? No, it's so much more than that. Dl 162 00:08:34,000 --> 00:08:38,680 Speaker 1: W runs researchers about dollars per test subjects. Actually, you 163 00:08:38,679 --> 00:08:41,480 Speaker 1: know what this really expensive water reminds me of? And 164 00:08:41,520 --> 00:08:44,199 Speaker 1: I know that this is totally off topic, but did 165 00:08:44,200 --> 00:08:46,240 Speaker 1: you know that the federal government actually sells a two 166 00:08:47,280 --> 00:08:50,920 Speaker 1: jar of peanut butter and there's just six ounces of 167 00:08:50,920 --> 00:08:53,880 Speaker 1: peanut butter in there. It's like a tiny jar. And 168 00:08:54,120 --> 00:08:56,520 Speaker 1: it also goes by this incredibly catchy name. Are you 169 00:08:56,520 --> 00:09:00,520 Speaker 1: ready for it? Standard Reference Material number two, three eights 170 00:09:00,559 --> 00:09:03,480 Speaker 1: of it. Oh, that sounds delicious, But why is it 171 00:09:03,520 --> 00:09:06,320 Speaker 1: actually so expensive? Is it more delicious? No, it's the 172 00:09:06,400 --> 00:09:09,840 Speaker 1: wonkiest reason ever. It's the super precise like peanut butter, 173 00:09:09,960 --> 00:09:14,200 Speaker 1: with specific levels of amino acids and fats and carcinogens. 174 00:09:14,280 --> 00:09:17,319 Speaker 1: And it's mostly used for quality controls so companies can 175 00:09:17,360 --> 00:09:20,400 Speaker 1: test their standards against the governments and make sure it 176 00:09:20,440 --> 00:09:23,679 Speaker 1: measures up. But as a result, no one actually eats 177 00:09:23,679 --> 00:09:26,720 Speaker 1: the peanut butter. It's just for lab purposes, which only 178 00:09:26,760 --> 00:09:28,760 Speaker 1: makes me want to try it more like with a 179 00:09:28,880 --> 00:09:32,920 Speaker 1: really cheap jelly. All well, let's get back to D. L. W. 180 00:09:33,080 --> 00:09:34,880 Speaker 1: Let me tell you what herman and his partners were 181 00:09:34,920 --> 00:09:37,160 Speaker 1: actually able to learn from having the Hods of tribe 182 00:09:37,200 --> 00:09:39,560 Speaker 1: drink it lay it on me. Well, first, let me 183 00:09:39,600 --> 00:09:41,800 Speaker 1: preface this by saying that the Hods are the kings 184 00:09:41,840 --> 00:09:45,440 Speaker 1: and queens of exercise. Every single day, the men trek 185 00:09:45,559 --> 00:09:48,120 Speaker 1: miles and miles to hunt for game with homemade bows 186 00:09:48,160 --> 00:09:51,440 Speaker 1: and arrows. They scale forty foot trees to hack tree 187 00:09:51,480 --> 00:09:54,760 Speaker 1: limbs with hatchets and gather wild honey. Now, the women 188 00:09:54,840 --> 00:09:57,679 Speaker 1: forage all day for wild berries and other edible plants 189 00:09:57,679 --> 00:10:00,360 Speaker 1: like tubers that they dig out at the ground with x. 190 00:10:00,880 --> 00:10:02,960 Speaker 1: Even the kids of the tribe are put to work 191 00:10:02,960 --> 00:10:06,760 Speaker 1: by hauling pails of water from a mile or more away. Okay, 192 00:10:06,760 --> 00:10:09,280 Speaker 1: so they're seriously active and no one sitting at their 193 00:10:09,320 --> 00:10:12,120 Speaker 1: desks right, definitely not. But what the researchers found was 194 00:10:12,160 --> 00:10:15,280 Speaker 1: that even though the Hadzas lives are far more physically demanding. 195 00:10:15,679 --> 00:10:17,960 Speaker 1: The amount of calories they ate and burned through in 196 00:10:17,960 --> 00:10:20,600 Speaker 1: the day was the same as in Europe and the US, 197 00:10:21,080 --> 00:10:23,960 Speaker 1: and the men went through about twenty six hundred calories 198 00:10:24,000 --> 00:10:27,000 Speaker 1: a day and the women burned through about nineteen hundred. 199 00:10:27,240 --> 00:10:30,360 Speaker 1: According to Herman, we looked at the data every way imaginable, 200 00:10:30,400 --> 00:10:33,800 Speaker 1: accounting for the effects of body size, fat percentage, age, 201 00:10:33,880 --> 00:10:37,520 Speaker 1: and sex. No difference at all, which is insane, isn't it. 202 00:10:37,559 --> 00:10:40,480 Speaker 1: I mean that you naturally assume that physically active people 203 00:10:40,520 --> 00:10:43,559 Speaker 1: would burn more calories, of course, but the research really 204 00:10:43,559 --> 00:10:46,000 Speaker 1: doesn't bear that out. In fact, they did a follow 205 00:10:46,080 --> 00:10:48,840 Speaker 1: up study with about three hundred participants and it showed 206 00:10:48,840 --> 00:10:51,679 Speaker 1: the exact same thing. The people who were the most 207 00:10:51,720 --> 00:10:54,400 Speaker 1: active burned the same daily amount of calories as those 208 00:10:54,400 --> 00:10:58,240 Speaker 1: who were only moderately, and the participants who barely left 209 00:10:58,280 --> 00:11:01,600 Speaker 1: the couch at all burned about two fewer calories than them, 210 00:11:01,640 --> 00:11:03,520 Speaker 1: the same amount they would have burned from a mere 211 00:11:03,600 --> 00:11:06,480 Speaker 1: thirty minutes of exercise. Doesn't seem to suggest that our 212 00:11:06,520 --> 00:11:10,400 Speaker 1: metabolisms are like fixed like. It almost seems like there's 213 00:11:10,440 --> 00:11:12,760 Speaker 1: a preset amount of calories that your body is willing 214 00:11:12,800 --> 00:11:15,800 Speaker 1: to burn in any given day, and no matter how 215 00:11:15,840 --> 00:11:18,240 Speaker 1: far you run or how many push ups you do, 216 00:11:18,400 --> 00:11:20,880 Speaker 1: you won't be able to top that max limit. But 217 00:11:21,000 --> 00:11:24,320 Speaker 1: my bigger question is this, why doesn't the Hadza hunter 218 00:11:24,480 --> 00:11:26,960 Speaker 1: burn more in day than the average office worker. Well, 219 00:11:27,000 --> 00:11:29,280 Speaker 1: I'm not sure we really have the answer to that yet, 220 00:11:29,320 --> 00:11:32,120 Speaker 1: but one thing I've seen researches suggest is that our 221 00:11:32,160 --> 00:11:35,280 Speaker 1: bodies account for the calories burned through physical activity by 222 00:11:35,360 --> 00:11:38,000 Speaker 1: dialing back on the number of calories we devote to 223 00:11:38,040 --> 00:11:42,720 Speaker 1: the background functions that keep us alive. About six of 224 00:11:42,760 --> 00:11:46,080 Speaker 1: the calories we burn each day go to these unseen 225 00:11:46,240 --> 00:11:49,880 Speaker 1: or unconscious processes, so it's possible that when our physical 226 00:11:49,920 --> 00:11:55,280 Speaker 1: activity pushes us beyond that other daily cloric expenditure, our 227 00:11:55,320 --> 00:11:57,440 Speaker 1: body is just cut back on the calories spin on 228 00:11:57,480 --> 00:12:00,800 Speaker 1: metabolic processes. This would help even the scales and keep 229 00:12:00,840 --> 00:12:03,400 Speaker 1: us from exceeding our preset energy budget for the day, 230 00:12:03,520 --> 00:12:07,600 Speaker 1: which is really cool but also disheartening. Right, no wonder, 231 00:12:07,640 --> 00:12:11,360 Speaker 1: I've got this paunch. I feel so betrayed unt I'll 232 00:12:11,400 --> 00:12:14,599 Speaker 1: take it too hard. So a fixed daily energy expenditure 233 00:12:14,600 --> 00:12:17,360 Speaker 1: limit is likely, and evolved trade meant to help conserve 234 00:12:17,440 --> 00:12:20,640 Speaker 1: our fat stores for when we really need them. I mean, 235 00:12:20,679 --> 00:12:23,000 Speaker 1: imagine if the Hotsa hunters were free to burn through 236 00:12:23,040 --> 00:12:25,760 Speaker 1: ten thousand calories during a hunt instead of the typical 237 00:12:25,800 --> 00:12:28,120 Speaker 1: two thousand or so, if they were to come up 238 00:12:28,120 --> 00:12:30,760 Speaker 1: empty handed, they would have lost five days worth of 239 00:12:30,800 --> 00:12:34,800 Speaker 1: calories in one with no prospects for replacing them. And 240 00:12:34,840 --> 00:12:37,160 Speaker 1: at that rate they're already limited. Fat stores will be 241 00:12:37,200 --> 00:12:39,440 Speaker 1: depleted in no time, and they'd find themselves on the 242 00:12:39,440 --> 00:12:42,319 Speaker 1: brink of starvation. Which is a great point but still 243 00:12:42,480 --> 00:12:44,800 Speaker 1: doesn't make you feel like maybe all that time spent 244 00:12:44,880 --> 00:12:47,719 Speaker 1: exercising was I don't know, kind of a waste. Well, no, 245 00:12:47,840 --> 00:12:50,640 Speaker 1: hold on a second, so don't forget that exercise has 246 00:12:50,679 --> 00:12:53,680 Speaker 1: all kinds of great benefits beyond weight loss. For starters, 247 00:12:53,720 --> 00:12:57,280 Speaker 1: exercises fantastic for your heart and blood vessels. It makes 248 00:12:57,280 --> 00:13:01,160 Speaker 1: your heart contract with greater force and frequency, which increases 249 00:13:01,160 --> 00:13:04,520 Speaker 1: blood flow leads to less artery clogging. There's also plenty 250 00:13:04,559 --> 00:13:07,520 Speaker 1: of evidence that exercise helps reduce the risk of some cancers, 251 00:13:07,559 --> 00:13:11,240 Speaker 1: as well as type two diabetes and cardiovascular disease. But 252 00:13:11,280 --> 00:13:14,360 Speaker 1: one of my favorite benefits of exercise that often goes overlooked. 253 00:13:14,720 --> 00:13:17,080 Speaker 1: Not only does it help strengthen your muscles, it helps 254 00:13:17,080 --> 00:13:20,720 Speaker 1: strengthen your bones too. Just like muscles, bones grow stronger 255 00:13:20,760 --> 00:13:23,040 Speaker 1: when they've been made to carry more weight than normal. 256 00:13:23,400 --> 00:13:26,439 Speaker 1: So your muscles contract during exercise, they apply force to 257 00:13:26,520 --> 00:13:29,400 Speaker 1: the bones that support those parts of the body. The 258 00:13:29,480 --> 00:13:32,280 Speaker 1: added force stimulates the bones and causes them to reinforce 259 00:13:32,320 --> 00:13:35,080 Speaker 1: themselves by building new tissue, which is really cool. But 260 00:13:35,200 --> 00:13:37,600 Speaker 1: you know, Will, I'm pretty sure we'd have to forfeit 261 00:13:37,640 --> 00:13:40,000 Speaker 1: our part time Genius membership cards if we miss the 262 00:13:40,040 --> 00:13:42,360 Speaker 1: chance to talk about some of the more amazing mental 263 00:13:42,400 --> 00:13:46,640 Speaker 1: benefits of exercise, like thanks to Fernando Gomez Pinia, a 264 00:13:46,760 --> 00:13:49,400 Speaker 1: neuro surgery professor at U c l A, we now 265 00:13:49,440 --> 00:13:52,200 Speaker 1: have some firm evidence of that connection. Namely, we know 266 00:13:52,320 --> 00:13:55,120 Speaker 1: that exercise increases the number of certain molecules in the 267 00:13:55,160 --> 00:13:58,280 Speaker 1: brain that are crucial for cognition. For example, there's one 268 00:13:58,320 --> 00:14:02,240 Speaker 1: molecule called brain derived I have neurotrophic factor, or b 269 00:14:02,360 --> 00:14:05,200 Speaker 1: d NF, and that stimulates the growth and survival of 270 00:14:05,200 --> 00:14:09,160 Speaker 1: brain cells and even helps facilitate communication between them. And 271 00:14:09,200 --> 00:14:11,360 Speaker 1: there have been some studies on rats that have shown 272 00:14:11,400 --> 00:14:14,680 Speaker 1: that physical activity boost b d NF levels in the hippocampus, 273 00:14:15,000 --> 00:14:16,960 Speaker 1: which is a part of the brain that's super important 274 00:14:17,000 --> 00:14:19,960 Speaker 1: for learning and even memory function, all right, but how 275 00:14:20,040 --> 00:14:22,720 Speaker 1: exactly does that help the rats? Well, that higher level 276 00:14:22,760 --> 00:14:25,400 Speaker 1: of b d NF actually allowed them to better remember 277 00:14:25,440 --> 00:14:28,320 Speaker 1: how they find their way through underwater mazes, and there 278 00:14:28,360 --> 00:14:30,920 Speaker 1: are tons of studies that suggest that same kind of 279 00:14:30,920 --> 00:14:34,280 Speaker 1: mental improvement from fitness happens in humans as well well. 280 00:14:34,280 --> 00:14:36,520 Speaker 1: A better brain is definitely a nice perk. But there's 281 00:14:36,560 --> 00:14:39,320 Speaker 1: another mental benefit to exercise that I like even more, 282 00:14:39,400 --> 00:14:42,200 Speaker 1: and that's mood enhancement. You probably heard of runners high 283 00:14:42,240 --> 00:14:44,920 Speaker 1: or exercise high, sure, and I've heard of both of those. 284 00:14:45,320 --> 00:14:47,760 Speaker 1: That's the euphoric feeling you get when you're need even 285 00:14:47,800 --> 00:14:50,560 Speaker 1: a strenuous workout, right. And while most people think it's 286 00:14:50,600 --> 00:14:54,040 Speaker 1: caused by endorphins, you know, those dandy neurochemicals that minimize 287 00:14:54,080 --> 00:14:57,800 Speaker 1: pain and stir up feelings of well being, exercise highs 288 00:14:57,800 --> 00:15:01,880 Speaker 1: are actually do more to neurotransmitters serotonin and neuro epinephrin, 289 00:15:02,360 --> 00:15:04,800 Speaker 1: So our bodies pump more of these throughout our nervous 290 00:15:04,800 --> 00:15:08,240 Speaker 1: systems during workouts, which elevates our mood and helps fight 291 00:15:08,240 --> 00:15:11,840 Speaker 1: back feelings of stress and depression. Okay, so maybe our 292 00:15:11,840 --> 00:15:13,960 Speaker 1: bodies aren't quite the turn coats I made them out 293 00:15:13,960 --> 00:15:17,000 Speaker 1: to be. But we've definitely been misinformed about the role 294 00:15:17,040 --> 00:15:19,080 Speaker 1: of exercise and weight loss. How do you think this 295 00:15:19,200 --> 00:15:22,720 Speaker 1: misunderstanding got started? And uh, is there really no basis 296 00:15:22,800 --> 00:15:25,760 Speaker 1: for thinking exercises an effective way to lose weight? Well, 297 00:15:25,760 --> 00:15:28,400 Speaker 1: there's a great questions. But before we exhaust ourselves, but 298 00:15:28,440 --> 00:15:30,440 Speaker 1: we check in with our guests for a little QUIZD. 299 00:15:37,440 --> 00:15:39,920 Speaker 1: So our guest today is partially responsible for our interest 300 00:15:39,960 --> 00:15:43,120 Speaker 1: in today's topic. His research has contributed to a much 301 00:15:43,120 --> 00:15:46,440 Speaker 1: better understanding of the relationship between our daily activity, our 302 00:15:46,520 --> 00:15:50,480 Speaker 1: daily calorie consumption and energy use and calorie burning and 303 00:15:50,840 --> 00:15:52,880 Speaker 1: all of that. And his name just kind of sounds 304 00:15:52,920 --> 00:15:55,320 Speaker 1: like he should have a theory named for him. Herman 305 00:15:55,360 --> 00:15:58,560 Speaker 1: Ponzer welcomed his part time genius. Hi, how you doing. 306 00:15:59,280 --> 00:16:01,520 Speaker 1: I'm doing well? Thank you? See what I mean, Mango, 307 00:16:01,520 --> 00:16:04,200 Speaker 1: I mean, can't you just imagine something called the Herman 308 00:16:04,280 --> 00:16:10,240 Speaker 1: Ponser theory of why we're still so freaking fast? Sounds right? Yeah, yeah, 309 00:16:10,280 --> 00:16:12,760 Speaker 1: we'll see if we can make that happen. So all right, Herman, Well, 310 00:16:12,840 --> 00:16:15,400 Speaker 1: let's just start with your research and Tanzania, I mean, 311 00:16:15,440 --> 00:16:17,520 Speaker 1: which got a lot of attention a few years ago, 312 00:16:17,600 --> 00:16:20,080 Speaker 1: and people are still talking about it. Can you tell 313 00:16:20,160 --> 00:16:22,440 Speaker 1: us why you were studying there and and and just 314 00:16:22,520 --> 00:16:26,720 Speaker 1: let our listeners know about your findings from that research. Sure. Well, 315 00:16:26,720 --> 00:16:29,680 Speaker 1: I'm an evolutionary biologist who's interested in how humans got 316 00:16:29,720 --> 00:16:31,040 Speaker 1: to be the way they are and how the human 317 00:16:31,080 --> 00:16:34,640 Speaker 1: body works from a kind of an evolutionary perspective. Um. 318 00:16:34,720 --> 00:16:38,640 Speaker 1: And of course humans we've all spent the most most 319 00:16:38,680 --> 00:16:41,640 Speaker 1: of our history as hunter gathers. If you go back, 320 00:16:41,720 --> 00:16:43,720 Speaker 1: you know, a couple of thousand years, all of us 321 00:16:43,760 --> 00:16:46,680 Speaker 1: are hunting and gathering, and you know, back two million 322 00:16:46,720 --> 00:16:48,560 Speaker 1: years ago with hunting gathering kind of starts. So we 323 00:16:48,600 --> 00:16:52,040 Speaker 1: have a long evolutionary history of hunting and gathering. Uh. 324 00:16:52,080 --> 00:16:55,840 Speaker 1: Not many populations hunt and gather anymore, um, but that 325 00:16:55,880 --> 00:16:59,840 Speaker 1: makes sort of understanding how they're lifestyles and they're you know, 326 00:17:00,000 --> 00:17:02,480 Speaker 1: their physiology works all the more important because we think 327 00:17:02,480 --> 00:17:05,800 Speaker 1: it's a really important sort of uh touchstone for understanding 328 00:17:05,840 --> 00:17:08,640 Speaker 1: how our bodies work, even in our weird environments today. 329 00:17:09,119 --> 00:17:12,040 Speaker 1: So in northern Candonia, there's a population called the Hotza, 330 00:17:12,119 --> 00:17:15,200 Speaker 1: who are one of the last um populations on Earth 331 00:17:15,280 --> 00:17:18,800 Speaker 1: that still hunt and gather regularly, so they don't have 332 00:17:18,840 --> 00:17:22,679 Speaker 1: any crops or domesticated animals or vehicles or guns or 333 00:17:22,720 --> 00:17:25,560 Speaker 1: machines or anything like that. They wake up every morning 334 00:17:25,800 --> 00:17:29,280 Speaker 1: and go off and hunt wild game and gather wild 335 00:17:29,280 --> 00:17:32,000 Speaker 1: plant foods, just like you know all of us, did 336 00:17:32,240 --> 00:17:36,439 Speaker 1: you know, just a few generations ago. Uh. And so 337 00:17:36,640 --> 00:17:40,480 Speaker 1: there's this really amazing and cool and generous and wonderful 338 00:17:40,520 --> 00:17:43,040 Speaker 1: population to work with to try to understand how that 339 00:17:43,119 --> 00:17:46,240 Speaker 1: lifestyle affects the way our bodies work. And one of 340 00:17:46,280 --> 00:17:48,400 Speaker 1: the fundamental things we wanted to understand was how many 341 00:17:48,400 --> 00:17:50,800 Speaker 1: calories they burned every day, because we thought, well, they're 342 00:17:50,840 --> 00:17:53,840 Speaker 1: so active. We know they're extremely active, but they've burned 343 00:17:53,840 --> 00:17:56,639 Speaker 1: tons more calories every day than we do here in 344 00:17:56,960 --> 00:17:58,840 Speaker 1: you know, in the US and Europe another kind of 345 00:17:58,880 --> 00:18:04,480 Speaker 1: westernized societies. And what we found instead, to our huge surprise, 346 00:18:05,040 --> 00:18:06,800 Speaker 1: was they burned the same number of calories every day 347 00:18:06,920 --> 00:18:09,920 Speaker 1: as you and I do. Wow. So if they were 348 00:18:09,960 --> 00:18:13,360 Speaker 1: wearing a fitbit or something like that, would it, I mean, 349 00:18:13,440 --> 00:18:16,440 Speaker 1: it would tell them that they had burned probably thousands 350 00:18:16,480 --> 00:18:18,800 Speaker 1: more calories than they actually had. Is that true or 351 00:18:19,040 --> 00:18:21,159 Speaker 1: they're right? Yeah, the fit that would tell them the 352 00:18:21,240 --> 00:18:25,040 Speaker 1: same lies that it tells you, which you know, however 353 00:18:25,080 --> 00:18:27,520 Speaker 1: active you are determines how many calories you burned. So 354 00:18:27,560 --> 00:18:29,680 Speaker 1: we know from other studies that we've done since that 355 00:18:29,840 --> 00:18:33,760 Speaker 1: they just to confirm our intuitions there. Uh, and this 356 00:18:33,800 --> 00:18:36,840 Speaker 1: is obvious to anybody who's worked with these With these folks, Uh, 357 00:18:37,000 --> 00:18:39,639 Speaker 1: they are incredibly physically active, sort of like three to 358 00:18:39,760 --> 00:18:44,600 Speaker 1: five times more physically active every day than the average westerner. Um. 359 00:18:44,680 --> 00:18:47,479 Speaker 1: And yet despite that, they're still burning in the same 360 00:18:47,520 --> 00:18:49,640 Speaker 1: number of calories as we do. So you know, they're 361 00:18:49,680 --> 00:18:52,680 Speaker 1: also really healthy. They have really healthy hearts and immune systems, 362 00:18:52,720 --> 00:18:54,760 Speaker 1: they don't have diabetes or anything like that. We think 363 00:18:54,800 --> 00:18:56,960 Speaker 1: the physical activity is a big part of that. So 364 00:18:57,000 --> 00:19:00,000 Speaker 1: it's important for their health, but it's not what keeps 365 00:19:00,000 --> 00:19:04,040 Speaker 1: and um, you know, sort of protected from obesity. Yeah, 366 00:19:04,040 --> 00:19:05,399 Speaker 1: and that's a big part of what we're trying to 367 00:19:05,400 --> 00:19:08,000 Speaker 1: remind our listeners of today is just because there's not 368 00:19:08,119 --> 00:19:10,480 Speaker 1: this as strong of a connection as we might have 369 00:19:10,520 --> 00:19:15,040 Speaker 1: thought between exercise and weight loss, they're obviously very real 370 00:19:15,080 --> 00:19:18,199 Speaker 1: benefits to doing the exercise that we do. Yeah, that's 371 00:19:18,200 --> 00:19:19,800 Speaker 1: a really important point because you know, when we came 372 00:19:19,840 --> 00:19:21,600 Speaker 1: out with this study and said, hey, look, these hunter 373 00:19:21,720 --> 00:19:26,080 Speaker 1: gather folks who are important to understand our history and 374 00:19:26,080 --> 00:19:29,000 Speaker 1: and how our bodies work. Um, and we thought that 375 00:19:29,000 --> 00:19:30,639 Speaker 1: they would burn so many work couties and then the 376 00:19:30,640 --> 00:19:33,919 Speaker 1: rest of us do. Turns out that that's not true. Um. 377 00:19:34,040 --> 00:19:37,480 Speaker 1: The response that we got was, you know, emails from 378 00:19:37,520 --> 00:19:39,320 Speaker 1: out of the blue saying, you know, you're destroying the 379 00:19:39,359 --> 00:19:42,760 Speaker 1: world because you're telling people not to exercise, right, And 380 00:19:42,800 --> 00:19:44,280 Speaker 1: of course that's not what we were saying at all. 381 00:19:44,440 --> 00:19:46,440 Speaker 1: You still to exercise, It's still important for your health. 382 00:19:46,560 --> 00:19:48,000 Speaker 1: It's just that it doesn't work the way that we 383 00:19:48,200 --> 00:19:50,520 Speaker 1: thought it worked, which was the exciting and fun part 384 00:19:50,520 --> 00:19:52,919 Speaker 1: of the science. You know, something that's been puzzling to us. 385 00:19:52,960 --> 00:19:55,520 Speaker 1: And this really isn't related exactly to the HODSA, but 386 00:19:56,240 --> 00:19:58,560 Speaker 1: you know, you remember during previous summer Olympics when you 387 00:19:58,640 --> 00:20:01,159 Speaker 1: see all these stories on Mike Phelps and his daily 388 00:20:01,200 --> 00:20:04,560 Speaker 1: diet and Michael Phelps questions, I knew it was exactly 389 00:20:04,840 --> 00:20:07,360 Speaker 1: so yeah, you had to know it was coming. So 390 00:20:07,359 --> 00:20:12,480 Speaker 1: so just I mean, and again that's this is called 391 00:20:12,480 --> 00:20:16,200 Speaker 1: the Ponser effect. So, um so, the the insane amount 392 00:20:16,240 --> 00:20:19,000 Speaker 1: of food that he would eat in order to keep 393 00:20:19,119 --> 00:20:22,280 Speaker 1: up with his fitness regiment. I mean, how was he 394 00:20:22,359 --> 00:20:25,680 Speaker 1: not super fat during this process. Yeah, well so there's 395 00:20:26,000 --> 00:20:28,439 Speaker 1: two I guess there's at least two pieces of this. 396 00:20:28,640 --> 00:20:32,160 Speaker 1: One is that, um, Michael Felts is not a normal 397 00:20:32,240 --> 00:20:36,240 Speaker 1: human and uh that's obvious if you watch him swim 398 00:20:36,240 --> 00:20:38,199 Speaker 1: and how fast he is an amazing as he is 399 00:20:38,240 --> 00:20:42,439 Speaker 1: an athlete. Um. And so you know what he's doing 400 00:20:42,520 --> 00:20:46,520 Speaker 1: during those those workout you know cycles where he's burning 401 00:20:46,520 --> 00:20:49,879 Speaker 1: ten talent colories. By the way, he's actually measured how 402 00:20:49,920 --> 00:20:51,960 Speaker 1: many calories he's bringing during these cycles. So we don't 403 00:20:52,000 --> 00:20:54,560 Speaker 1: really know. You see numbers thrown around like eight thousand 404 00:20:54,560 --> 00:20:59,320 Speaker 1: calories a thing, um, which maybe it is true. Um. 405 00:20:59,359 --> 00:21:00,760 Speaker 1: We know that if you look at like a Tour 406 00:21:00,840 --> 00:21:04,680 Speaker 1: de France cyclist like is happening right now, um, or 407 00:21:04,680 --> 00:21:07,520 Speaker 1: where you look at Michael Phelps during or another Olympic 408 00:21:07,680 --> 00:21:11,520 Speaker 1: athlete during these really intense training and competition times, that 409 00:21:11,680 --> 00:21:13,960 Speaker 1: for a few weeks or even you know a couple 410 00:21:14,000 --> 00:21:18,240 Speaker 1: of months, your body can burn tons more calories than 411 00:21:18,400 --> 00:21:22,240 Speaker 1: the would be normal. Um. What we don't know is 412 00:21:22,280 --> 00:21:24,800 Speaker 1: what are the limits to that. I don't think Michael 413 00:21:24,800 --> 00:21:27,960 Speaker 1: Pelps can burn it susan colories a day forever. I 414 00:21:28,040 --> 00:21:31,000 Speaker 1: think that you know, his body would break down. Um. 415 00:21:31,080 --> 00:21:33,160 Speaker 1: And I think that you know, he can do that 416 00:21:33,480 --> 00:21:36,239 Speaker 1: during certain periods. And the other piece of this is that, 417 00:21:36,359 --> 00:21:38,320 Speaker 1: you know, there's a reason that not everybody's Michael Phelps. 418 00:21:38,400 --> 00:21:41,560 Speaker 1: And it might well be that people who are flexible 419 00:21:41,640 --> 00:21:43,359 Speaker 1: enough and they're metabolic rate to to sort of be 420 00:21:43,359 --> 00:21:46,320 Speaker 1: able to handle that huge influx are the people who 421 00:21:46,720 --> 00:21:50,200 Speaker 1: end up being Olympic athletes, you know. Um. And I 422 00:21:50,240 --> 00:21:52,400 Speaker 1: think the third thing I'd say is it just goes 423 00:21:52,440 --> 00:21:55,040 Speaker 1: to show you, um, you know, we we think of 424 00:21:55,560 --> 00:21:59,520 Speaker 1: I think sometimes the paleo diet folks imagine these elite 425 00:21:59,560 --> 00:22:03,080 Speaker 1: athletes as being kind of indicative of what our path 426 00:22:03,280 --> 00:22:06,440 Speaker 1: was like, right Like if we were only if we 427 00:22:06,520 --> 00:22:08,800 Speaker 1: only exercise like Michael Phelps, we'd all be back in 428 00:22:08,840 --> 00:22:11,920 Speaker 1: the sort of state of nature. Um. And in fact, 429 00:22:12,240 --> 00:22:14,800 Speaker 1: people like Michael Felts are way on the extreme of 430 00:22:14,800 --> 00:22:17,760 Speaker 1: of beyond what's what's normal for any human society anywhere. 431 00:22:17,840 --> 00:22:21,800 Speaker 1: The cycial activity levels extremely too, extremely high. Well, I 432 00:22:21,840 --> 00:22:23,880 Speaker 1: feel like we've been ponsored. So it's time to turn 433 00:22:23,920 --> 00:22:27,600 Speaker 1: the tables here and put into the test. We're gonna 434 00:22:27,600 --> 00:22:29,840 Speaker 1: play a little quiz with herman here. What's our quiz 435 00:22:29,840 --> 00:22:32,600 Speaker 1: called today? Mango. It's called real, vintage diet or something 436 00:22:32,600 --> 00:22:34,359 Speaker 1: we just made up. All right, So this is a 437 00:22:34,359 --> 00:22:36,480 Speaker 1: pretty simple game. We're going to read you a list 438 00:22:36,480 --> 00:22:38,440 Speaker 1: of diets and you're going to tell us if they're 439 00:22:38,480 --> 00:22:41,119 Speaker 1: real or whether we just made them up. Does that 440 00:22:41,200 --> 00:22:44,960 Speaker 1: sound sound good to you? Herman? All right? Here we 441 00:22:45,000 --> 00:22:48,800 Speaker 1: go five questions. The first one the seven day milk diet, 442 00:22:49,000 --> 00:22:52,600 Speaker 1: real or made up? Um, I'll tell you this. A 443 00:22:52,680 --> 00:22:56,360 Speaker 1: guy ran across the US in two other drinking almost 444 00:22:57,040 --> 00:23:01,080 Speaker 1: drinking milk and almost nothing else. So I want to say. 445 00:23:01,119 --> 00:23:03,679 Speaker 1: I want to say true, because full a lot of 446 00:23:03,880 --> 00:23:08,639 Speaker 1: good stuff for you. That sounds terrible, Yeah, it's true. 447 00:23:08,720 --> 00:23:12,040 Speaker 1: In nine seventies, pamphlet put off by the California Milk 448 00:23:12,040 --> 00:23:16,320 Speaker 1: Advisory Board advised eating less and drinking milk with every meal. Wow, 449 00:23:16,560 --> 00:23:20,160 Speaker 1: that sounds horrible, and then running just sounds then run 450 00:23:20,200 --> 00:23:23,560 Speaker 1: across the country, all right. Number two the sexy pineapple diet, 451 00:23:23,600 --> 00:23:28,440 Speaker 1: which happens to come from Denmark. Um, the sexy pineapple diet. 452 00:23:29,000 --> 00:23:31,919 Speaker 1: I'm gonna say there's no but there's no way. I 453 00:23:31,960 --> 00:23:34,800 Speaker 1: studied people, and to tell you about people is no 454 00:23:35,080 --> 00:23:39,920 Speaker 1: human culture. Pines, pineapple sexy. I'm gonna say no to 455 00:23:40,000 --> 00:23:44,600 Speaker 1: the s this is actually true? And where did this 456 00:23:44,680 --> 00:23:47,160 Speaker 1: come from? Yeah, buzz, we had found this diet book 457 00:23:47,160 --> 00:23:50,520 Speaker 1: for nineteen seventy and the Chicago Tribune it actually reviewed 458 00:23:50,560 --> 00:23:52,919 Speaker 1: it and they panned it, saying, if you're ready to 459 00:23:52,960 --> 00:23:57,560 Speaker 1: be miserable about something, this diet guarantees twenty four hour dismay. 460 00:23:58,840 --> 00:24:03,600 Speaker 1: So here we go, alright, one out of two, number three, 461 00:24:04,480 --> 00:24:08,720 Speaker 1: Chowder through the thirty day Chowder, Power diet, Chowder through 462 00:24:08,800 --> 00:24:13,080 Speaker 1: the thirty day Chowder Power Diet. I just I don't 463 00:24:13,080 --> 00:24:14,840 Speaker 1: want that to be true, so I'm gonna say no. 464 00:24:19,119 --> 00:24:21,000 Speaker 1: You know, Mano, I don't know how many skills you have, 465 00:24:21,119 --> 00:24:22,960 Speaker 1: but this is one of your skills to make up 466 00:24:23,040 --> 00:24:25,560 Speaker 1: things like this that just sounds so real. So yes, 467 00:24:25,640 --> 00:24:28,679 Speaker 1: this is this is in fact fault. Right, Yeah, it's false. 468 00:24:29,160 --> 00:24:31,399 Speaker 1: There was a tune around the clock diet for a while. 469 00:24:31,600 --> 00:24:33,920 Speaker 1: Tune around the clock. Alright, so he's two for three. 470 00:24:34,000 --> 00:24:37,480 Speaker 1: Let's see the next one. Skinny like Lincoln the Gettysburg 471 00:24:37,680 --> 00:24:44,639 Speaker 1: ration diet um fault because Lincoln was skinny because he 472 00:24:44,760 --> 00:24:47,520 Speaker 1: was he had a condition. I think I don't think 473 00:24:47,520 --> 00:24:51,399 Speaker 1: he was skinny because I would he ate. I'm yeah, right. 474 00:24:52,520 --> 00:24:54,679 Speaker 1: So the last one here, he's three out of four 475 00:24:55,520 --> 00:25:00,200 Speaker 1: the Drinking Man's Diet. Do you have any deep held 476 00:25:00,200 --> 00:25:04,560 Speaker 1: on this? I mean man side and I got to 477 00:25:04,600 --> 00:25:06,480 Speaker 1: be give me detailed to kind of gives it away, 478 00:25:06,520 --> 00:25:11,719 Speaker 1: doesn't it. Um? So so tell me nothing, tell me nothing, um. True, 479 00:25:11,880 --> 00:25:16,320 Speaker 1: Absolutely true, It's true. I like that. You didn't need 480 00:25:16,359 --> 00:25:18,600 Speaker 1: any more detail, but we'll give you a little. It 481 00:25:18,680 --> 00:25:22,359 Speaker 1: was subtitled how to Lose Weight with Minimum Willpower and 482 00:25:22,440 --> 00:25:26,520 Speaker 1: it was basically in nineteen sixties Atkins Diet. It was 483 00:25:26,560 --> 00:25:29,439 Speaker 1: based on eating steak and drinking nothing but whiskey. All right, 484 00:25:29,480 --> 00:25:32,119 Speaker 1: Well that's pretty impressive. So so how's herman done today? 485 00:25:33,000 --> 00:25:36,200 Speaker 1: Herman did an incredible four for five, And in addition 486 00:25:36,240 --> 00:25:38,560 Speaker 1: to our harder than admiration, we're actually gonna send him 487 00:25:38,600 --> 00:25:40,560 Speaker 1: a copy of a book we found called Help Lord 488 00:25:40,600 --> 00:25:44,200 Speaker 1: the Devil Wants Me Fat, a scriptural approach to trim 489 00:25:44,240 --> 00:25:48,119 Speaker 1: and attractive bodies. That's gonna be a great prize. Well, Herman, 490 00:25:48,200 --> 00:25:50,800 Speaker 1: thanks so much for joining us today. Thank you. It 491 00:25:50,840 --> 00:26:08,200 Speaker 1: was a lot of fun. You're listening to part time 492 00:26:08,240 --> 00:26:11,800 Speaker 1: genius and we're talking about the surprising truth behind exercise. 493 00:26:12,240 --> 00:26:14,280 Speaker 1: So mego before the break I was wondering who to 494 00:26:14,359 --> 00:26:16,520 Speaker 1: blame for the fact that exercise has sort of become 495 00:26:16,560 --> 00:26:19,600 Speaker 1: synonymous with weight loss in our minds. Any ideas on that. 496 00:26:19,680 --> 00:26:24,280 Speaker 1: You're asking me to name names, I actually am. Yeah. Well, 497 00:26:24,320 --> 00:26:26,320 Speaker 1: I did some digging, and while it might be a 498 00:26:26,320 --> 00:26:29,320 Speaker 1: little unfair to lay the entire blame for a widespread 499 00:26:29,400 --> 00:26:34,000 Speaker 1: cultural misunderstanding on one individual, there's no denying that John 500 00:26:34,080 --> 00:26:36,959 Speaker 1: Mayor makes a pretty good scapegoat. I'll take it. So, 501 00:26:37,080 --> 00:26:40,439 Speaker 1: who is who is? John Mayor? Said? Well, John is 502 00:26:40,480 --> 00:26:44,040 Speaker 1: this French American scientist and nutritionists who did some high 503 00:26:44,040 --> 00:26:48,280 Speaker 1: profile research on the physiology of hunger and metabolism during 504 00:26:48,280 --> 00:26:51,600 Speaker 1: the mid twentieth century. In fact, thanks to his breakthrough 505 00:26:51,680 --> 00:26:55,280 Speaker 1: studies on rats, babies, and school girls in the nineteen fifties, 506 00:26:55,600 --> 00:26:58,600 Speaker 1: Mayor became the first researcher to make a connection between 507 00:26:58,720 --> 00:27:02,120 Speaker 1: exercise and weight loss. He showed that the less physically 508 00:27:02,119 --> 00:27:04,760 Speaker 1: active a person was, the more likely they were to 509 00:27:04,800 --> 00:27:06,840 Speaker 1: be overweight. All right, hold on, so you're saying that 510 00:27:06,960 --> 00:27:10,360 Speaker 1: prior to Mayor, nobody thought that burning calories through exercise 511 00:27:10,440 --> 00:27:13,480 Speaker 1: might result in weight loss. Yeah, it sounds so crazy, 512 00:27:13,600 --> 00:27:16,119 Speaker 1: but that line of thinking was unpopular in the scientific 513 00:27:16,119 --> 00:27:20,520 Speaker 1: community before Mayor came along. In fact, during the nineteen thirties, 514 00:27:20,560 --> 00:27:23,240 Speaker 1: some scientists actually argued that bed rest was the most 515 00:27:23,240 --> 00:27:26,360 Speaker 1: effective way to treat a beast patients, not exercise. Can 516 00:27:26,400 --> 00:27:28,200 Speaker 1: you imagine this a are you guys going to hike 517 00:27:28,240 --> 00:27:29,720 Speaker 1: without me? And my doctor says I need to shut 518 00:27:29,760 --> 00:27:32,400 Speaker 1: a few pounds. I'm just gonna lie right here right. 519 00:27:32,680 --> 00:27:35,160 Speaker 1: It sounds like one of those crazy diets or miracle 520 00:27:35,240 --> 00:27:39,040 Speaker 1: cures you sometimes hear about that you know never actually works. 521 00:27:39,440 --> 00:27:42,560 Speaker 1: But back to Mayor. He actually served as an advisor 522 00:27:42,640 --> 00:27:45,000 Speaker 1: to both the White House and to the w h O, 523 00:27:45,440 --> 00:27:47,720 Speaker 1: which made him a top name in nutrition and one 524 00:27:47,760 --> 00:27:50,240 Speaker 1: of the most influential figures in the public health sphere 525 00:27:50,600 --> 00:27:53,560 Speaker 1: thanks to the connections he made between exercise and weight loss. 526 00:27:53,880 --> 00:27:56,120 Speaker 1: The idea of getting fit took off in the sixties 527 00:27:56,119 --> 00:28:00,480 Speaker 1: and seventies, which led to this uh thriving jim industry 528 00:28:00,520 --> 00:28:02,840 Speaker 1: and a cultural obsession with working out as a way 529 00:28:02,880 --> 00:28:05,840 Speaker 1: to lose weight and to live healthier, and it clearly 530 00:28:05,920 --> 00:28:09,199 Speaker 1: snowballed from their Obesity rates have risen dramatically over the 531 00:28:09,240 --> 00:28:11,719 Speaker 1: last few decades is more and more of the population 532 00:28:11,760 --> 00:28:14,920 Speaker 1: began trading jobs on farms and in factories for these 533 00:28:14,920 --> 00:28:18,040 Speaker 1: desk jobs. It probably made sense to conclude that this 534 00:28:18,119 --> 00:28:21,480 Speaker 1: more sedentary lifestyle was the cause of all that weight gain, right, 535 00:28:21,560 --> 00:28:24,800 Speaker 1: But today's scientists, no, that's not the full story. It's 536 00:28:24,800 --> 00:28:27,480 Speaker 1: actually a case of mixing up cause and effect. People 537 00:28:27,520 --> 00:28:31,160 Speaker 1: aren't overweight because they're inactive. They're inactive because they're overweight. 538 00:28:31,480 --> 00:28:33,560 Speaker 1: It's harder to stay active when you weigh more, so 539 00:28:33,880 --> 00:28:36,040 Speaker 1: many people just don't. Well, it makes sense because it 540 00:28:36,080 --> 00:28:39,080 Speaker 1: points back to the real culprit behind the obesity epidemic, 541 00:28:39,120 --> 00:28:42,280 Speaker 1: and that's diet. We really have an obscene amount of 542 00:28:42,280 --> 00:28:44,920 Speaker 1: food options today, and thanks to lifestyles that are more 543 00:28:44,920 --> 00:28:48,960 Speaker 1: sedentary compared to previous generations, we have plenty of opportunities 544 00:28:49,000 --> 00:28:51,960 Speaker 1: to over indulge on all of that variety, and we 545 00:28:52,080 --> 00:28:55,560 Speaker 1: take full advantage of this. For instance, researchers at Harvard 546 00:28:55,600 --> 00:28:58,760 Speaker 1: conducted to surveys on food consumption. One was in the 547 00:28:58,800 --> 00:29:01,120 Speaker 1: mid nineteen seventies and then a second in the mid 548 00:29:01,280 --> 00:29:03,840 Speaker 1: nine es, and they found that although the number of 549 00:29:03,880 --> 00:29:07,040 Speaker 1: calories expended didn't change significantly in that time period, the 550 00:29:07,120 --> 00:29:09,760 Speaker 1: number of calories consumed in a day increased by two 551 00:29:09,840 --> 00:29:12,640 Speaker 1: hundred and sixty eight calories for men and a hundred 552 00:29:12,640 --> 00:29:15,080 Speaker 1: and forty three for women. Yeah, it really does sound 553 00:29:15,160 --> 00:29:18,800 Speaker 1: like our unfettered access to affordable, no muss prepared foods 554 00:29:18,840 --> 00:29:21,920 Speaker 1: has taken a toll on our waistlines. I mean, we're 555 00:29:22,000 --> 00:29:26,760 Speaker 1: constantly surrounded by food, and according to Brian wantsonk uh Cornell, 556 00:29:26,880 --> 00:29:29,680 Speaker 1: researcher who studies how we eat, we eat the amount 557 00:29:29,720 --> 00:29:31,960 Speaker 1: of food we do mostly because of what's around us. 558 00:29:32,360 --> 00:29:36,080 Speaker 1: In his book Mindless Eating, Brian writes, we overeat not 559 00:29:36,160 --> 00:29:39,480 Speaker 1: because of hunger, but because of family and friends. Packages 560 00:29:39,520 --> 00:29:43,720 Speaker 1: and plates, names and numbers, labels and lights, colors and candles, 561 00:29:43,760 --> 00:29:48,200 Speaker 1: shapes and smells, distractions and distances, cupboards and containers. This 562 00:29:48,240 --> 00:29:51,080 Speaker 1: list is almost as endless as it's invisible. I think 563 00:29:51,120 --> 00:29:54,640 Speaker 1: he was just showing off his illiterative ability. That was impressive. 564 00:29:55,280 --> 00:29:57,680 Speaker 1: So it's not so much that are less active lifestyles 565 00:29:57,680 --> 00:29:59,680 Speaker 1: have made us gain weight, but that we've developed the 566 00:29:59,680 --> 00:30:02,880 Speaker 1: bad habit of filling that downtime with mindless eating brought 567 00:30:02,920 --> 00:30:05,880 Speaker 1: on by food cues. Exactly. It's the reverse principle of 568 00:30:05,920 --> 00:30:08,800 Speaker 1: out of sight, out of mind. Brian calls it insight 569 00:30:08,920 --> 00:30:11,800 Speaker 1: in stomach creative. This guy is just full of them, 570 00:30:11,840 --> 00:30:14,640 Speaker 1: and it's a serious problem. For example, if you have 571 00:30:14,680 --> 00:30:17,000 Speaker 1: cookies or chips sitting out on your counter, there's a 572 00:30:17,040 --> 00:30:19,640 Speaker 1: strong chance you'll weigh about eight pounds more than a 573 00:30:19,640 --> 00:30:22,720 Speaker 1: person who doesn't. Oh wow, we really are that suggestible, 574 00:30:22,720 --> 00:30:25,480 Speaker 1: aren't we. Yeah, and it gets much worse. Soda is 575 00:30:25,520 --> 00:30:27,400 Speaker 1: one of the big examples that gets brought up as 576 00:30:27,440 --> 00:30:30,760 Speaker 1: a contributor to rising ob CD rates, and it looks 577 00:30:30,800 --> 00:30:33,120 Speaker 1: like that's for a good reason. Apparently, if you keep 578 00:30:33,160 --> 00:30:35,920 Speaker 1: soda on hand in plain sight, like front and center 579 00:30:35,960 --> 00:30:39,280 Speaker 1: in your fridge, you're gonna weigh on average twenty five 580 00:30:39,320 --> 00:30:41,480 Speaker 1: pounds more than a person who doesn't. Okay, you're just 581 00:30:41,520 --> 00:30:44,160 Speaker 1: scaring me now, my god. So we've got to figure 582 00:30:44,160 --> 00:30:45,680 Speaker 1: out a way to keep our weight in check. And 583 00:30:45,720 --> 00:30:49,400 Speaker 1: it's clear now that exercise alone isn't going to cut it. Still, 584 00:30:49,440 --> 00:30:51,680 Speaker 1: I don't want to write off weight loss through exercise 585 00:30:51,760 --> 00:30:54,760 Speaker 1: completely like the nineteen thirties type. So let's try to 586 00:30:54,800 --> 00:30:57,880 Speaker 1: make sense of how to really maximize its benefits. Great, 587 00:30:57,960 --> 00:31:00,440 Speaker 1: but before we get into that, let's break for quiz. 588 00:31:09,720 --> 00:31:12,280 Speaker 1: Welcome back to part time Genius. So here we are 589 00:31:12,400 --> 00:31:17,400 Speaker 1: Mango four chiseled bodies all in one room, or rather 590 00:31:18,040 --> 00:31:22,040 Speaker 1: rather two personal trainers and two podcasters. I think yeah, 591 00:31:22,040 --> 00:31:25,520 Speaker 1: but there's a twelve pack between the four most I'm 592 00:31:25,560 --> 00:31:27,160 Speaker 1: with you on that. So, so who do we have 593 00:31:27,240 --> 00:31:29,680 Speaker 1: us in with us in studio today? Mango, We've got 594 00:31:29,760 --> 00:31:33,120 Speaker 1: Janet Wortz and Mario Jordan's from the form Athletic Club 595 00:31:33,200 --> 00:31:35,680 Speaker 1: in Pont City Market right here in Atlanta. That is 596 00:31:35,720 --> 00:31:38,480 Speaker 1: just right downstairs from us. So welcome guys, thanks for 597 00:31:38,480 --> 00:31:40,600 Speaker 1: having us having us. All right, So we were just 598 00:31:40,680 --> 00:31:44,080 Speaker 1: talking before before we started out that, Mario, you were 599 00:31:44,080 --> 00:31:46,680 Speaker 1: telling us a little bit about your your breakfast regiment 600 00:31:46,760 --> 00:31:49,800 Speaker 1: every single day. What is it that usually? Um, it's 601 00:31:50,760 --> 00:31:54,240 Speaker 1: basically two cups of old meal and six hard boards. 602 00:31:57,200 --> 00:32:00,680 Speaker 1: It's basically, so say, okay hard Well, you didn't say 603 00:32:00,680 --> 00:32:02,600 Speaker 1: that before because I was gonna ask if we're doing 604 00:32:02,600 --> 00:32:05,720 Speaker 1: this like Rocky? So no, no, yeah, have you have 605 00:32:05,760 --> 00:32:09,360 Speaker 1: you ever done that? Can't do it? Okay, it's horrible. 606 00:32:09,760 --> 00:32:13,080 Speaker 1: I don't do scrambled eggs or yeah, you're always horrible. 607 00:32:13,680 --> 00:32:15,479 Speaker 1: How about you? Janee? Do you how many do you have? 608 00:32:15,560 --> 00:32:19,160 Speaker 1: Eight eggs? Oh? No, probably throughout the day I could, 609 00:32:19,320 --> 00:32:23,160 Speaker 1: but um, generally I'll have about four egg whites, sometimes 610 00:32:23,240 --> 00:32:28,360 Speaker 1: one whole egg and either protein pancake or ezekio bread oatmeal. 611 00:32:28,440 --> 00:32:31,160 Speaker 1: It just takes so long to eat for me, so 612 00:32:31,280 --> 00:32:35,840 Speaker 1: I really don't know how Mario gets through. And actually 613 00:32:35,840 --> 00:32:38,040 Speaker 1: with the hard boiled eggs, I have this problem where 614 00:32:38,040 --> 00:32:39,720 Speaker 1: I used to when I would travel a lot and 615 00:32:39,760 --> 00:32:41,640 Speaker 1: I would stop in and grab a couple of hard 616 00:32:41,640 --> 00:32:44,120 Speaker 1: boiled eggs real quick, and I would eat them too fast, 617 00:32:44,560 --> 00:32:46,560 Speaker 1: and I just knew that I was dying because I 618 00:32:46,560 --> 00:32:49,480 Speaker 1: couldn't breathe, like you're choking up because they're so dry. 619 00:32:49,600 --> 00:32:52,960 Speaker 1: Does that ever happen to you? Sometimes? Most of them? 620 00:32:53,280 --> 00:32:54,880 Speaker 1: I mean it depends on how long you cook it. 621 00:32:54,960 --> 00:33:04,520 Speaker 1: Something just overcooked and it will be watching. Yeah, this 622 00:33:04,640 --> 00:33:07,080 Speaker 1: actually speaks to what we've been talking about today. That 623 00:33:07,240 --> 00:33:10,840 Speaker 1: is important as exercises. Clearly, diet is very important. That's 624 00:33:10,880 --> 00:33:12,960 Speaker 1: why these two are in such great shape because they're 625 00:33:12,960 --> 00:33:15,960 Speaker 1: not exactly slacky. Now do you guys have your cheat 626 00:33:16,040 --> 00:33:18,760 Speaker 1: days or how does that work for you guys? Um? 627 00:33:18,800 --> 00:33:22,320 Speaker 1: For me, I prep my food um pretty much weekly, 628 00:33:22,440 --> 00:33:25,760 Speaker 1: whether it's for seven days or three days. And then yes, 629 00:33:25,800 --> 00:33:28,560 Speaker 1: I do cheat. I'm human. I actually work out and 630 00:33:28,640 --> 00:33:31,080 Speaker 1: eat right, so I can't eat it like that's one 631 00:33:31,120 --> 00:33:33,360 Speaker 1: of the things I do. So yes, okay, how about you. 632 00:33:33,720 --> 00:33:37,960 Speaker 1: I'm the same way. Um, I have cheap meals here 633 00:33:37,960 --> 00:33:43,200 Speaker 1: and there, that Derito's Loco stock, uh, milkshakes from Chick 634 00:33:43,240 --> 00:33:47,959 Speaker 1: fil A good, those are insane. That's my advice right now. Yea, 635 00:33:48,040 --> 00:33:53,680 Speaker 1: mine is case so Mexican food in case. All right. Well, 636 00:33:53,720 --> 00:33:56,240 Speaker 1: I know you guys have put yourself through a lot 637 00:33:56,360 --> 00:33:58,760 Speaker 1: as as as personal trainers, and you work really hard 638 00:33:58,760 --> 00:34:00,840 Speaker 1: every day. I don't think you've ever seeing anything like 639 00:34:00,840 --> 00:34:02,800 Speaker 1: you're going to see with today's quiz, though, Mango, what 640 00:34:02,840 --> 00:34:04,520 Speaker 1: are we putting them to the challenge with? Today? We're 641 00:34:04,520 --> 00:34:07,920 Speaker 1: gonna play a game called real Exercise fat or nonsensical 642 00:34:07,960 --> 00:34:10,279 Speaker 1: equipment we just made up? All right? So this game 643 00:34:10,360 --> 00:34:12,640 Speaker 1: is super easy. We're gonna read you six questions and 644 00:34:12,680 --> 00:34:14,480 Speaker 1: you just have to tell us if the gym equipment 645 00:34:14,480 --> 00:34:17,319 Speaker 1: we're talking about is real or something we made up. 646 00:34:17,360 --> 00:34:19,719 Speaker 1: You got it, got it, all right. So because we 647 00:34:19,760 --> 00:34:21,880 Speaker 1: know you like a challenge, we're gonna put you against 648 00:34:21,960 --> 00:34:24,879 Speaker 1: one another, all right, So, Janey, we're gonna let you 649 00:34:24,920 --> 00:34:28,000 Speaker 1: go first. Now. The first one is and I'll read 650 00:34:28,040 --> 00:34:31,800 Speaker 1: you the tagline along with it. Okay, it's Hawaii chair. 651 00:34:32,360 --> 00:34:35,239 Speaker 1: If you can sit, you can get fit.

Or was this a 656 00:34:47,600 --> 00:34:52,480 Speaker 1: real exercise fad? Oh god, I really I watch a 657 00:34:52,520 --> 00:34:56,160 Speaker 1: lot of infomercials. Yeah. Um, I'm gonna say that it's real. 658 00:34:56,480 --> 00:35:00,320 Speaker 1: It is real, a one for one so you really 659 00:35:00,320 --> 00:35:03,080 Speaker 1: like move around moves.

Is this a real 667 00:35:31,719 --> 00:35:35,919 Speaker 1: exercise fad or equipment we made up? Uh, I'm gonna 668 00:35:35,920 --> 00:35:41,480 Speaker 1: say it's they're so good at this.

Number three, 671 00:35:46,120 --> 00:35:50,000 Speaker 1: This is back to you, Janet. The mulby revolving hammock 672 00:35:50,320 --> 00:35:54,000 Speaker 1: guaranteed to make your spine young.

Is this a 675 00:35:59,760 --> 00:36:02,840 Speaker 1: real exercise fat or something we made up? I was 676 00:36:02,880 --> 00:36:05,719 Speaker 1: trying to visualize it, and I couldn't even visualize that. 677 00:36:05,880 --> 00:36:09,120 Speaker 1: So I'm gonna say it's made up. We finally have 678 00:36:09,160 --> 00:36:12,520 Speaker 1: a wrong answer. They're not perfect. We thought this is 679 00:36:12,560 --> 00:36:16,480 Speaker 1: a real exercise fat and super bizarre. A picture of this. 680 00:36:17,960 --> 00:36:20,800 Speaker 1: Number four, Mario, this was back to you air shorts 681 00:36:20,920 --> 00:36:24,719 Speaker 1: great for shedding body moisture. These versatile, inflatable shorts were 682 00:36:24,760 --> 00:36:27,960 Speaker 1: supposed to bake your stomach, thighs, and bottom, causing you 683 00:36:28,000 --> 00:36:30,680 Speaker 1: to sweat as you worked out or wandered about town. 684 00:36:31,520 --> 00:36:36,799 Speaker 1: Is this a real exercise fat or something we made up? Uh? 685 00:36:37,360 --> 00:36:44,480 Speaker 1: As ridiculous as it sounds, let's say it's real ridiculous. 686 00:36:45,800 --> 00:36:48,799 Speaker 1: The pressure is on. Okay, I think this is a 687 00:36:48,840 --> 00:36:50,959 Speaker 1: two pointer, though, if I'm not mistaken, if I'm reading 688 00:36:50,960 --> 00:36:54,080 Speaker 1: the rules correctly, the official rules of our game here okay, 689 00:36:54,480 --> 00:36:57,759 Speaker 1: tag suit, the it new way to weight loss, A 690 00:36:57,800 --> 00:36:59,959 Speaker 1: weighted suit you can wear as you run around playing 691 00:37:00,040 --> 00:37:03,640 Speaker 1: adult tag with your friends. Just don't stay on base. 692 00:37:04,520 --> 00:37:06,680 Speaker 1: Is this a real fat or something we made up? 693 00:37:09,719 --> 00:37:15,040 Speaker 1: A real thing? Oh no, it's equipment we made off. 694 00:37:15,040 --> 00:37:17,240 Speaker 1: She didn't see as I was trying to make eye contact. 695 00:37:18,640 --> 00:37:21,520 Speaker 1: All right, here we go. Now this one, actually, unfortunately 696 00:37:21,560 --> 00:37:23,520 Speaker 1: Mario comes with a penalty if you miss it of 697 00:37:23,600 --> 00:37:25,759 Speaker 1: negative one. So let's see. So the pressure is on 698 00:37:25,800 --> 00:37:30,960 Speaker 1: the game. One last one. This one is called Twist 699 00:37:31,000 --> 00:37:35,320 Speaker 1: in Tone, the exerciser that's fun, easy and works. Basically, 700 00:37:35,360 --> 00:37:38,000 Speaker 1: it was a plastic lazy Susan that you could stand 701 00:37:38,000 --> 00:37:41,360 Speaker 1: on while doing the twist. Totally worth the five dollars 702 00:37:41,360 --> 00:37:46,879 Speaker 1: and cents. Real fat or something we made up? It's real? 703 00:37:47,440 --> 00:37:56,759 Speaker 1: Oh I remember seeing something like that. Oh wow. All right, 704 00:37:56,800 --> 00:37:58,640 Speaker 1: we'll tell us how our contestants have done here today, 705 00:37:58,719 --> 00:38:01,719 Speaker 1: Mango well as all ways, first place wins a handwritten 706 00:38:01,719 --> 00:38:04,400 Speaker 1: note from us to your mom or boss, singing your praises. 707 00:38:04,480 --> 00:38:07,399 Speaker 1: So Mario, that's coming your way. And because we don't 708 00:38:07,400 --> 00:38:10,080 Speaker 1: want anyone going home empty handed, Jane, you're getting a 709 00:38:10,120 --> 00:38:13,440 Speaker 1: pair of hander pants. The number one underwear inspired gloves 710 00:38:13,480 --> 00:38:19,600 Speaker 1: on the market today. Well, thank you guys so much 711 00:38:19,640 --> 00:38:21,719 Speaker 1: for joining us today on Part Time Genius. Thank you 712 00:38:21,760 --> 00:38:38,440 Speaker 1: for having us. So we were talking before about how 713 00:38:38,480 --> 00:38:40,880 Speaker 1: we've been conditioned over the last fifty years or so 714 00:38:40,960 --> 00:38:44,040 Speaker 1: to associate exercise with weight loss and what has turned 715 00:38:44,040 --> 00:38:46,799 Speaker 1: out to be a fairly unhealthy way. Yeah. I mean, 716 00:38:46,960 --> 00:38:49,440 Speaker 1: a lot of people start workout routines because they expect 717 00:38:49,440 --> 00:38:52,319 Speaker 1: the pounds to just melt off based on everything we've 718 00:38:52,320 --> 00:38:54,480 Speaker 1: been told about how to stay fit. But when that 719 00:38:54,520 --> 00:38:57,520 Speaker 1: doesn't happen as much as we expect, and the payoff 720 00:38:57,560 --> 00:39:00,680 Speaker 1: seems too slow or too little for the amount of effort, well, 721 00:39:00,719 --> 00:39:03,640 Speaker 1: then it's good body or gym membership exactly. And that's 722 00:39:03,680 --> 00:39:06,640 Speaker 1: the real shame. So many of us put unhealthy pressure 723 00:39:06,640 --> 00:39:10,200 Speaker 1: on ourselves as a result of these unrealistic expectations that 724 00:39:10,239 --> 00:39:12,800 Speaker 1: we put on an exercise, and the end result is 725 00:39:12,840 --> 00:39:15,080 Speaker 1: often that we blame ourselves and just give up on 726 00:39:15,160 --> 00:39:17,960 Speaker 1: losing weight altogether. And that also causes us to miss 727 00:39:17,960 --> 00:39:20,360 Speaker 1: out on the very real mental and physical benefits of 728 00:39:20,440 --> 00:39:23,640 Speaker 1: regular exercise. So let's try to help avoid that. Mango. 729 00:39:23,719 --> 00:39:26,600 Speaker 1: Let's put the true effectiveness of exercise for weight loss 730 00:39:26,600 --> 00:39:30,120 Speaker 1: into perspective. Okay, Well, first off, I think we should 731 00:39:30,160 --> 00:39:32,040 Speaker 1: say that the main reason why a lot of people's 732 00:39:32,040 --> 00:39:34,759 Speaker 1: exercise routines go could put is the same reason why 733 00:39:34,840 --> 00:39:37,640 Speaker 1: sixty of diet or is returned to their original weight 734 00:39:37,680 --> 00:39:41,439 Speaker 1: within three years. As diet and behavior expert Charlotte Markey 735 00:39:41,520 --> 00:39:44,879 Speaker 1: told Scientific American, people think too much about short term 736 00:39:44,920 --> 00:39:48,759 Speaker 1: goals and don't think enough about sustainable changes. If you're 737 00:39:48,760 --> 00:39:51,000 Speaker 1: going to lose weight, you have to change your behaviors 738 00:39:51,040 --> 00:39:53,279 Speaker 1: for the rest of your life for otherwise you gain 739 00:39:53,320 --> 00:39:55,640 Speaker 1: it back. And that's not a sexy message because it 740 00:39:55,640 --> 00:39:58,160 Speaker 1: seems daunting. Yeah, it does. And does she have any 741 00:39:58,200 --> 00:40:01,000 Speaker 1: suggestions on what kind of lifelong they aavioral changes people 742 00:40:01,080 --> 00:40:04,320 Speaker 1: might actually be able to stomach. Yeah, it's all about sustainability. 743 00:40:04,600 --> 00:40:06,960 Speaker 1: So for example, people don't have to completely cut out 744 00:40:07,080 --> 00:40:09,799 Speaker 1: entire food groups or ice cream or anything like that. 745 00:40:10,200 --> 00:40:12,719 Speaker 1: But we should strive for small scale changes that we 746 00:40:12,840 --> 00:40:15,560 Speaker 1: stick to, like dropping a soda or two from our 747 00:40:15,600 --> 00:40:17,880 Speaker 1: daily diet so we can cut a few hundred calories 748 00:40:17,880 --> 00:40:20,720 Speaker 1: from our intake, or staying on the lookout to avoid 749 00:40:20,760 --> 00:40:23,680 Speaker 1: mindless eating. Well, I think that's the kind of sustainability 750 00:40:23,760 --> 00:40:26,200 Speaker 1: is what we should aim for with exercise too. I mean, 751 00:40:26,239 --> 00:40:29,160 Speaker 1: once you stop thinking about the physical activity primarily is 752 00:40:29,160 --> 00:40:31,480 Speaker 1: a way to lose weight, it frees us up to 753 00:40:31,520 --> 00:40:34,600 Speaker 1: add exercise into our routines and enjoyable ways that will 754 00:40:34,640 --> 00:40:37,680 Speaker 1: be less likely to give up on totally. And despite 755 00:40:37,719 --> 00:40:40,840 Speaker 1: all we've learned about the limitations of calorie burning through workouts, 756 00:40:41,040 --> 00:40:43,560 Speaker 1: there actually are some ways to use exercise to help 757 00:40:43,640 --> 00:40:46,440 Speaker 1: us with our weight loss efforts. Like what. Well, for 758 00:40:46,520 --> 00:40:49,520 Speaker 1: one thing, exercise helps distract us from our food cravings. 759 00:40:49,719 --> 00:40:52,560 Speaker 1: It gives people something else to concentrate on, and there 760 00:40:52,600 --> 00:40:55,440 Speaker 1: are some forms of exercise that can help maximize the 761 00:40:55,440 --> 00:40:58,200 Speaker 1: amount of weight you lose from fat rather than muscle. Well, 762 00:40:58,200 --> 00:41:00,439 Speaker 1: that's a good point. So we've mostly been talking about 763 00:41:00,440 --> 00:41:03,319 Speaker 1: exercise in broad terms, but it's worth mentioning that most 764 00:41:03,400 --> 00:41:07,000 Speaker 1: forms of exercise fall into one of two broad groups. 765 00:41:07,000 --> 00:41:12,000 Speaker 1: So we've got aerobic type exercise like running, biking, swimming, rowing, etcetera, 766 00:41:12,360 --> 00:41:15,160 Speaker 1: which helps strengthen your heart and build stamina, and then 767 00:41:15,200 --> 00:41:18,920 Speaker 1: anaerobic exercise such as weightlifting or sprinting, which helps increase 768 00:41:19,000 --> 00:41:22,160 Speaker 1: lean muscle mass. Right, and both types of workout will 769 00:41:22,560 --> 00:41:24,719 Speaker 1: burn fat and help you lose a little weight, But 770 00:41:25,040 --> 00:41:28,160 Speaker 1: studies have found that aerobic training does provide the advantage 771 00:41:28,160 --> 00:41:30,759 Speaker 1: in terms of most weight and fat burned. So if 772 00:41:30,760 --> 00:41:32,399 Speaker 1: you're looking for the best way to burn the most 773 00:41:32,440 --> 00:41:36,240 Speaker 1: fat and the least amount of time, aerobic exercises probably 774 00:41:36,280 --> 00:41:38,080 Speaker 1: the way to go. That's true, but I wouldn't trade 775 00:41:38,120 --> 00:41:41,200 Speaker 1: in your barbells for running shoes just yet. If sustainability 776 00:41:41,280 --> 00:41:43,920 Speaker 1: really is the goal, it's not a bad idea to 777 00:41:43,960 --> 00:41:47,000 Speaker 1: gain some extra lean muscle. The research shows that an 778 00:41:47,000 --> 00:41:49,960 Speaker 1: increase in muscle can speed up your resting metabolic rate, 779 00:41:50,040 --> 00:41:52,920 Speaker 1: plus booster strength, and even lead to a better night's sleep. 780 00:41:53,440 --> 00:41:55,239 Speaker 1: So if you're really in it for the long haul, 781 00:41:55,600 --> 00:41:57,720 Speaker 1: the best strategy is probably do a little bit of both, 782 00:41:57,800 --> 00:42:00,160 Speaker 1: which sounds like a smart plan. And other thing I 783 00:42:00,200 --> 00:42:03,680 Speaker 1: always wonder about is fitness trackers like garments and Tom 784 00:42:03,760 --> 00:42:06,960 Speaker 1: Tom's and fit fits. Lots of people swear by them 785 00:42:06,960 --> 00:42:10,200 Speaker 1: and they're everywhere nowadays. Like I even saw that McDonald's 786 00:42:10,239 --> 00:42:12,640 Speaker 1: was giving them away in happy Meals last year and 787 00:42:12,880 --> 00:42:16,560 Speaker 1: what had to have have been one of the most ironic promotions. 788 00:42:16,560 --> 00:42:19,239 Speaker 1: So everybody has these things drapped to their risks, But 789 00:42:19,400 --> 00:42:21,920 Speaker 1: did they really help us lose weight or to come 790 00:42:21,920 --> 00:42:24,320 Speaker 1: any healthier. Well, you know, we recently had a listener 791 00:42:24,320 --> 00:42:26,680 Speaker 1: asked a similar question. So I did some digging, and 792 00:42:26,719 --> 00:42:29,640 Speaker 1: it turns out not really. I mean, there isn't a 793 00:42:29,680 --> 00:42:31,880 Speaker 1: ton of long term research yet on the effects of 794 00:42:31,920 --> 00:42:35,640 Speaker 1: wearable fitness technology. It hasn't yet been around long enough. 795 00:42:35,719 --> 00:42:38,279 Speaker 1: But most of the short term studies have found that 796 00:42:38,280 --> 00:42:41,319 Speaker 1: wearing fitness trackers only lead to a small boost and 797 00:42:41,320 --> 00:42:44,840 Speaker 1: physical activity, not nearly enough to lead to any improvements 798 00:42:44,840 --> 00:42:48,319 Speaker 1: in overall health. And what's worse, one study found that 799 00:42:48,320 --> 00:42:50,520 Speaker 1: when people were given the option of wearing a fitness 800 00:42:50,520 --> 00:42:53,120 Speaker 1: tracker or not, the people who chose to wear it 801 00:42:53,239 --> 00:42:56,120 Speaker 1: actually lost less weight than those who didn't know. It 802 00:42:56,200 --> 00:42:59,120 Speaker 1: was seven points seven pounds compared to the thirteen pounds 803 00:42:59,120 --> 00:43:01,880 Speaker 1: of those who went to cliss Which isn't exactly a 804 00:43:01,920 --> 00:43:05,000 Speaker 1: bringing endorsement, no, but it's not completely a lost cause. 805 00:43:05,040 --> 00:43:07,440 Speaker 1: I mean, keeping track of steps and calories can be 806 00:43:07,520 --> 00:43:10,439 Speaker 1: a useful motivator for some folks, provided they don't take 807 00:43:10,480 --> 00:43:13,719 Speaker 1: that success as an excuse to reward themselves with their 808 00:43:13,760 --> 00:43:17,600 Speaker 1: extra large pizza. Right, and uh, we've seen how that goes, right, 809 00:43:17,760 --> 00:43:20,840 Speaker 1: So fitness trackers can definitely be a helpful weapon in 810 00:43:20,880 --> 00:43:23,200 Speaker 1: the never ending battle of the bulge. But just like 811 00:43:23,280 --> 00:43:26,360 Speaker 1: exercise or dieting, they're no guarantee of weight loss on 812 00:43:26,400 --> 00:43:29,120 Speaker 1: their own. Well, I don't know about you will, but 813 00:43:29,239 --> 00:43:32,560 Speaker 1: I'll just talk about exercise has me feeling a little competitive. 814 00:43:32,800 --> 00:43:34,120 Speaker 1: Where do you say we go toe to toe in 815 00:43:34,160 --> 00:43:36,279 Speaker 1: the part time genius? All right, I'm ready when you 816 00:43:36,280 --> 00:43:50,439 Speaker 1: are a mango m Yeah, alright. So here's a tip 817 00:43:50,480 --> 00:43:54,440 Speaker 1: that comes straight from one of America's favorite fitness gurus, Barbie. 818 00:43:54,880 --> 00:43:57,880 Speaker 1: In slumber Party, Barbie came to your place with a 819 00:43:58,000 --> 00:44:00,560 Speaker 1: diet book in hand, and the only tip in it 820 00:44:01,080 --> 00:44:05,080 Speaker 1: don't eat terrible. Uh though, here's one that's even worse, 821 00:44:05,360 --> 00:44:08,680 Speaker 1: the tapeworm diet. Back in the early twentieth century, diet 822 00:44:08,719 --> 00:44:11,279 Speaker 1: pills filled with tapeworms were sold over the counter with 823 00:44:11,320 --> 00:44:13,680 Speaker 1: the promise that you could eat more and still lose weight. 824 00:44:14,160 --> 00:44:16,520 Speaker 1: And of course, when the baby tapeworms grew up to 825 00:44:16,560 --> 00:44:20,360 Speaker 1: be like these twenty five foot monstrosities and started causing 826 00:44:20,400 --> 00:44:23,680 Speaker 1: things like meningitis and dimension in their hosts, the government 827 00:44:23,719 --> 00:44:26,440 Speaker 1: decided that the weight loss through worms was overrated, and 828 00:44:26,480 --> 00:44:29,040 Speaker 1: they banned the pills. Diet coke might not be that 829 00:44:29,160 --> 00:44:31,760 Speaker 1: much better for you than regular coke, but it certainly 830 00:44:31,920 --> 00:44:34,800 Speaker 1: is lighter. While I can of coke will sink in water, 831 00:44:35,120 --> 00:44:37,920 Speaker 1: you know, kind of like a bulldog, diet coke actually 832 00:44:37,960 --> 00:44:41,520 Speaker 1: floats more like a hot dog. I'm glad you put 833 00:44:41,520 --> 00:44:44,879 Speaker 1: the dog and just really helps you understand what floating is. 834 00:44:46,120 --> 00:44:48,920 Speaker 1: My favorite exercise item from the seventies is the Sauna 835 00:44:49,000 --> 00:44:52,239 Speaker 1: exercise suit, which looks nothing like a suit. It's more 836 00:44:52,280 --> 00:44:56,520 Speaker 1: like a tinfoil marshmallow man contraption that promised to help 837 00:44:56,520 --> 00:44:59,000 Speaker 1: you shed pounds as you just went about your daily business. 838 00:45:00,200 --> 00:45:02,880 Speaker 1: Calvin Coolige's main exercise in the office was through an 839 00:45:02,960 --> 00:45:06,439 Speaker 1: electric horse, kind of like a mechanical bull. He'd write 840 00:45:06,440 --> 00:45:09,160 Speaker 1: it three times a day on various settings, from saunter 841 00:45:09,360 --> 00:45:12,719 Speaker 1: to gallop, but the regiment sounded so silly he kept 842 00:45:12,719 --> 00:45:14,920 Speaker 1: it a secret until it accidentally bucked him from the 843 00:45:14,960 --> 00:45:17,520 Speaker 1: saddle and had to be put down by an electrician. 844 00:45:18,800 --> 00:45:21,759 Speaker 1: So that's pretty good. But here's a great tip from 845 00:45:21,760 --> 00:45:24,760 Speaker 1: the seventeen hundreds, if you want to lose weight, stay 846 00:45:24,760 --> 00:45:29,440 Speaker 1: away from swamps. In seventy seven, a so called scientist 847 00:45:29,520 --> 00:45:32,400 Speaker 1: named Thomas Short observed that beast people seemed to live 848 00:45:32,480 --> 00:45:35,040 Speaker 1: near swamps, so it was important. Work on the matter, 849 00:45:35,480 --> 00:45:39,640 Speaker 1: titled The Causes and Effects of Corpulents naturally suggested there 850 00:45:39,719 --> 00:45:42,800 Speaker 1: was only one smart way to lose weight, move away 851 00:45:42,840 --> 00:45:45,560 Speaker 1: from swamps. Yeah, that swamped. It makes a whole lot 852 00:45:45,600 --> 00:45:47,560 Speaker 1: of sense. I think I gotta give you the title 853 00:45:47,600 --> 00:45:50,440 Speaker 1: on this when congratulations, Mango. I think that's it for 854 00:45:50,440 --> 00:45:52,800 Speaker 1: today's show.

Kristin McNeil does the editing thing. 860 00:46:19,840 --> 00:46:21,799 Speaker 1: Noel Brown made the theme song and does the mixy 861 00:46:21,880 --> 00:46:25,279 Speaker 1: mixy sound thing.
