1 00:00:02,560 --> 00:00:05,080 Speaker 1: Guess what, Mango, what's that? Will do? You remember back 2 00:00:05,080 --> 00:00:07,120 Speaker 1: in two thousand and eight when Michael Phelps had that 3 00:00:07,240 --> 00:00:09,600 Speaker 1: daily diet that got so much attention because he was 4 00:00:09,640 --> 00:00:12,360 Speaker 1: eating these insane amounts of food. Yeah, he was eating 5 00:00:12,400 --> 00:00:15,200 Speaker 1: something like eight thousand calories a day. You try twelve 6 00:00:15,240 --> 00:00:17,680 Speaker 1: thousand cowers a day during his peak training, he need 7 00:00:17,720 --> 00:00:21,560 Speaker 1: a whole pizza, pound of pasta, three fried eggs, French toast, 8 00:00:21,640 --> 00:00:24,560 Speaker 1: multiple burgers, and it seemed like anything else he could 9 00:00:24,560 --> 00:00:27,440 Speaker 1: get his hands on, which seems so gross but also 10 00:00:27,680 --> 00:00:31,360 Speaker 1: kind of the best thing ever. And during those same Olympics, 11 00:00:31,440 --> 00:00:35,280 Speaker 1: Hussein Bolt reportedly ate forty seven thousand calories worth of 12 00:00:35,360 --> 00:00:40,000 Speaker 1: chicken McNuggets. Yeah, he was eating them with fries for breakfast, lunch, 13 00:00:40,240 --> 00:00:44,199 Speaker 1: and dinner. That seems at less great. Yeah, but wouldn't 14 00:00:44,240 --> 00:00:47,040 Speaker 1: sixteen year old Mango think of it's pretty incredible. So 15 00:00:47,080 --> 00:00:49,279 Speaker 1: I started thinking about this, and I know you've been 16 00:00:49,280 --> 00:00:51,239 Speaker 1: getting back into the tennis, and I've been running a 17 00:00:51,240 --> 00:00:53,920 Speaker 1: good bet these past few years. But I thought, if 18 00:00:53,960 --> 00:00:56,120 Speaker 1: I could just take this to the extreme, I may 19 00:00:56,120 --> 00:00:58,959 Speaker 1: be able to follow a similar diet. Like let's say 20 00:00:59,000 --> 00:01:01,240 Speaker 1: I'm running twenty miles a week, right, now, and I 21 00:01:01,320 --> 00:01:04,440 Speaker 1: just keep doubling that for the next five weeks, I'd 22 00:01:04,480 --> 00:01:07,160 Speaker 1: be running six hundred and forty miles a week by 23 00:01:07,200 --> 00:01:09,440 Speaker 1: the end of this. I'm so excited about this. Then 24 00:01:09,480 --> 00:01:12,360 Speaker 1: I could eat like twelve Chipotle burritos every day and 25 00:01:12,440 --> 00:01:15,040 Speaker 1: still have room for a half dozen Wendy Spicy Chicken 26 00:01:15,080 --> 00:01:17,880 Speaker 1: sandwiches and maybe even a couple of those naked chicken 27 00:01:17,920 --> 00:01:20,520 Speaker 1: choloopas after I run for the border. It's gonna be great. 28 00:01:21,200 --> 00:01:24,280 Speaker 1: But after our research for today's episodes, Science may have 29 00:01:24,360 --> 00:01:27,720 Speaker 1: crushed my dreams again. It turns out there's not quite 30 00:01:27,760 --> 00:01:30,480 Speaker 1: as strong of a connection between exercise and weight loss 31 00:01:30,520 --> 00:01:32,960 Speaker 1: as we once thought. So that's what we're gonna talk 32 00:01:33,000 --> 00:01:58,160 Speaker 1: about today, Stupid Science Day their podcast listeners, Welcome to 33 00:01:58,200 --> 00:02:00,600 Speaker 1: Part Time Genius. I'm Will Pearson and as always I'm 34 00:02:00,680 --> 00:02:03,520 Speaker 1: joined by my good friend Manes Ticketer, and today we're 35 00:02:03,520 --> 00:02:07,640 Speaker 1: diving into the topic of exercise, its benefits, it's limitations, 36 00:02:08,120 --> 00:02:10,520 Speaker 1: whether it can actually help us shed some unwanted pounds, 37 00:02:10,680 --> 00:02:13,800 Speaker 1: and if it really makes us healthier people. And fear not, 38 00:02:13,960 --> 00:02:16,520 Speaker 1: we also have a couple of our patented, ridiculous quizzes 39 00:02:16,560 --> 00:02:18,799 Speaker 1: along the way. Who've we got on the line today, Mango. 40 00:02:18,880 --> 00:02:21,800 Speaker 1: So we'll be talking to Herman Pontzer, and anthropology professor 41 00:02:21,800 --> 00:02:24,720 Speaker 1: at Hunter College in New York City. He's responsible for 42 00:02:24,800 --> 00:02:28,080 Speaker 1: some truly incredible research on exercise, and he's gonna help 43 00:02:28,160 --> 00:02:30,240 Speaker 1: us get to the bottom of just how useful physical 44 00:02:30,280 --> 00:02:33,360 Speaker 1: activity really is for burning calories. We're also going to 45 00:02:33,400 --> 00:02:35,600 Speaker 1: talk to a couple of personal trainers and see if 46 00:02:35,600 --> 00:02:37,320 Speaker 1: we can whip them into shape through the power of 47 00:02:37,320 --> 00:02:41,320 Speaker 1: our trivia. Right, So, before today's episode, I would have 48 00:02:41,320 --> 00:02:43,800 Speaker 1: told you that exercising is probably the best way to 49 00:02:43,840 --> 00:02:47,000 Speaker 1: lose weight simply based on the conventional wisdom of calories in, 50 00:02:47,200 --> 00:02:50,359 Speaker 1: calories out. I mean that sounds sensible, right, Sure, We're 51 00:02:50,360 --> 00:02:52,760 Speaker 1: taken calories through what we eat and drink and then 52 00:02:52,840 --> 00:02:55,640 Speaker 1: burn them up through exercise. The more you exercise, the 53 00:02:55,680 --> 00:02:58,120 Speaker 1: more calories you burn, and the more weight you lose. 54 00:02:58,320 --> 00:03:00,959 Speaker 1: It just makes sense, it does. But there are actually 55 00:03:01,000 --> 00:03:03,120 Speaker 1: all these studies conducted over the last few years that 56 00:03:03,200 --> 00:03:06,760 Speaker 1: suggests exercise really isn't an effective way to lose excess weight. 57 00:03:07,200 --> 00:03:10,400 Speaker 1: For example, Dr Timothy Church at the Pennington Biomedical Research 58 00:03:10,440 --> 00:03:13,119 Speaker 1: Center at l s U. He held an experiment where 59 00:03:13,200 --> 00:03:16,639 Speaker 1: hundreds of overweight women were given strict workout regiments for 60 00:03:16,680 --> 00:03:19,720 Speaker 1: six months. The one group of them exercised a little 61 00:03:19,720 --> 00:03:22,160 Speaker 1: over an hour each week, another one for a little 62 00:03:22,160 --> 00:03:25,799 Speaker 1: over two hours, and another for over three hours. There 63 00:03:25,880 --> 00:03:27,960 Speaker 1: was also a fourth group that stuck to their typical 64 00:03:28,080 --> 00:03:31,720 Speaker 1: routine and didn't exercise at all. And against all logic 65 00:03:31,760 --> 00:03:34,200 Speaker 1: and fairness, there was no major difference in the weight 66 00:03:34,240 --> 00:03:36,680 Speaker 1: loss between the women who had exercised and the ones 67 00:03:36,720 --> 00:03:38,360 Speaker 1: who had And how pissed would you be if you 68 00:03:38,400 --> 00:03:41,120 Speaker 1: were that three hour group. In fact, some of the 69 00:03:41,160 --> 00:03:44,600 Speaker 1: women in the exercise groups actually gained weight, which doesn't 70 00:03:44,640 --> 00:03:47,360 Speaker 1: seem fair at all. I mean, they put into work, 71 00:03:47,400 --> 00:03:49,840 Speaker 1: they deserve a reward. Well, it's funny you should say that, 72 00:03:49,920 --> 00:03:53,720 Speaker 1: because Church actually concluded that the rewards were the problem. 73 00:03:53,760 --> 00:03:56,760 Speaker 1: You know, exercise stimulates appetite, and many of the women 74 00:03:56,800 --> 00:04:00,640 Speaker 1: counteracted their work by over eating afterward. Church suggested that 75 00:04:00,640 --> 00:04:02,560 Speaker 1: it was justified in their minds. Is kind of a 76 00:04:02,640 --> 00:04:06,120 Speaker 1: self reward for all the energy that exerted through exercise. Yeah, 77 00:04:06,160 --> 00:04:07,880 Speaker 1: we hear that sort of thinking all the time, like 78 00:04:08,040 --> 00:04:10,800 Speaker 1: cheat days and junk food rewards for going to the gym. 79 00:04:10,960 --> 00:04:14,280 Speaker 1: But if we're canceling out the calories we burn, then 80 00:04:14,280 --> 00:04:17,520 Speaker 1: we're probably imagining our workouts to be much more effective 81 00:04:17,560 --> 00:04:20,080 Speaker 1: than they really are. I mean, the Department of Health 82 00:04:20,080 --> 00:04:23,000 Speaker 1: and Human Services recommends people aim for at least thirty 83 00:04:23,000 --> 00:04:26,039 Speaker 1: minutes of physical activity every day, but at thirty minute 84 00:04:26,080 --> 00:04:29,360 Speaker 1: workout that only burns about two hundred calories, and the 85 00:04:29,440 --> 00:04:32,800 Speaker 1: average slice of pizza contains close to like three hundred calories. 86 00:04:33,120 --> 00:04:35,200 Speaker 1: So you can see how the map doesn't quite work. 87 00:04:35,360 --> 00:04:38,800 Speaker 1: It's really just not fair at all. But it isn't 88 00:04:38,800 --> 00:04:42,600 Speaker 1: just those powerful post workout indulgences that counteract calories burned 89 00:04:42,640 --> 00:04:45,760 Speaker 1: through exercise. You know, the things we consume in preparation 90 00:04:45,880 --> 00:04:48,880 Speaker 1: for even during a workout can also take a toll, 91 00:04:49,080 --> 00:04:51,200 Speaker 1: which is a good point. I mean, those two hundred 92 00:04:51,200 --> 00:04:53,680 Speaker 1: calories you burned during your thirty minutes on the treadmill, 93 00:04:54,040 --> 00:04:56,400 Speaker 1: every single one goes right back into your body thanks 94 00:04:56,400 --> 00:04:58,960 Speaker 1: to that bottle of gatorade or that energy bar you 95 00:04:59,000 --> 00:05:01,560 Speaker 1: might have scarfed down while running right right, And the 96 00:05:01,600 --> 00:05:03,719 Speaker 1: same goes for the bagel or the oatmeal used to 97 00:05:03,760 --> 00:05:06,839 Speaker 1: carbo load before your workout, And we think the energy 98 00:05:06,880 --> 00:05:09,040 Speaker 1: from these meals is going to help us power through 99 00:05:09,200 --> 00:05:11,880 Speaker 1: and burn more calories at the gym, But it's actually 100 00:05:11,920 --> 00:05:14,279 Speaker 1: the calories from those pregame foods that are going to 101 00:05:14,320 --> 00:05:16,840 Speaker 1: get burned off first. And why is that Well, because 102 00:05:16,839 --> 00:05:19,640 Speaker 1: sugar from what you've just consumed will still be floating 103 00:05:19,680 --> 00:05:23,120 Speaker 1: freely in your bloodstream, and it takes muscle tissue much 104 00:05:23,200 --> 00:05:25,440 Speaker 1: less energy to take that sugar than it does to 105 00:05:25,480 --> 00:05:28,720 Speaker 1: burn off the existing fat stores. So your most recent 106 00:05:28,800 --> 00:05:31,480 Speaker 1: meal will always be the first to go during a workout. 107 00:05:31,680 --> 00:05:34,160 Speaker 1: But we can always just exercise a little longer, right, 108 00:05:34,200 --> 00:05:37,599 Speaker 1: I mean, once those preliminary calories are gone, our muscle 109 00:05:37,640 --> 00:05:40,480 Speaker 1: cells will start chipping away at storage fat for fuel. Well, 110 00:05:40,520 --> 00:05:43,400 Speaker 1: I mean yes and no. According to some breakthrough research 111 00:05:43,440 --> 00:05:45,840 Speaker 1: from Herman Ponzer, there are a lot of assumptions we've 112 00:05:45,880 --> 00:05:49,240 Speaker 1: been making about human metabolism that they're not quite right. 113 00:05:49,360 --> 00:05:52,039 Speaker 1: So you know, it's true that a longer workout would 114 00:05:52,080 --> 00:05:55,599 Speaker 1: result in more calories burned and even some from storage fat. 115 00:05:56,240 --> 00:05:58,279 Speaker 1: But we know there's a limit to how many calories 116 00:05:58,320 --> 00:06:00,719 Speaker 1: your body will metabolize in any gift and day, So 117 00:06:00,920 --> 00:06:03,760 Speaker 1: I'm definitely intrigued. But before we get too far into this, 118 00:06:03,880 --> 00:06:07,760 Speaker 1: we should probably clarify the basics of metabolism, all right, well, 119 00:06:07,760 --> 00:06:11,760 Speaker 1: I'll let you do that. Go for it, okay. So 120 00:06:12,480 --> 00:06:15,719 Speaker 1: metabolism is basically the sum of all the processes that 121 00:06:15,760 --> 00:06:19,960 Speaker 1: takes place in our bodies. We're talking digestion, respiration, the 122 00:06:20,000 --> 00:06:23,359 Speaker 1: production of cells, the movement of substances between cells, you 123 00:06:23,440 --> 00:06:27,080 Speaker 1: name it, and all these processes require energy, which our 124 00:06:27,120 --> 00:06:30,800 Speaker 1: bodies released from the calories we consume. So even without 125 00:06:30,839 --> 00:06:34,359 Speaker 1: exercise and other forms of physical activity, we still burned 126 00:06:34,440 --> 00:06:38,120 Speaker 1: through or metabolize a huge number of calories simply by 127 00:06:38,160 --> 00:06:41,560 Speaker 1: being alive. Yeah, exactly. So back to Herman Ponsers World 128 00:06:41,640 --> 00:06:46,080 Speaker 1: Shattering Research and February's issue of Scientific American, Herman shared 129 00:06:46,120 --> 00:06:49,720 Speaker 1: findings from his study of the Hadza tribe and rule Tanzania. 130 00:06:49,880 --> 00:06:52,440 Speaker 1: He and other researchers spent a whole month living with 131 00:06:52,480 --> 00:06:55,200 Speaker 1: the Hatsa, who were one of the last traditional hunter 132 00:06:55,200 --> 00:06:58,400 Speaker 1: gatherer cultures left on earth. That was during this time 133 00:06:58,400 --> 00:07:01,200 Speaker 1: that Herman and his partners recorded measurements of the daily 134 00:07:01,320 --> 00:07:05,080 Speaker 1: energy expenditures of a couple dozen tribesmen and women. So 135 00:07:05,160 --> 00:07:07,520 Speaker 1: this allowed them to compare the daily calorie burn of 136 00:07:07,520 --> 00:07:10,440 Speaker 1: a society in which every member is highly active to 137 00:07:10,520 --> 00:07:12,960 Speaker 1: a Western society like our own, and which members are 138 00:07:12,960 --> 00:07:17,080 Speaker 1: more you know, sedentary. Well, back up a second. You 139 00:07:17,080 --> 00:07:21,040 Speaker 1: said the researchers measured the hadzas daily energy expenditure, But 140 00:07:21,080 --> 00:07:23,760 Speaker 1: I'm wondering how they pull that off. Are you really 141 00:07:23,800 --> 00:07:25,840 Speaker 1: wondering that mango or are you just sensing there's an 142 00:07:25,840 --> 00:07:30,200 Speaker 1: opportunity here to talk about doubly labeled water? Of course 143 00:07:30,240 --> 00:07:32,320 Speaker 1: it is, you know, I love the d l W. 144 00:07:33,360 --> 00:07:36,360 Speaker 1: Doubly Labeled water is the special water in which the 145 00:07:36,480 --> 00:07:40,640 Speaker 1: hydrogen and oxygen molecules have been either partly or entirely 146 00:07:40,680 --> 00:07:43,880 Speaker 1: replaced with heavy isotopes that aren't usually found in the 147 00:07:43,960 --> 00:07:47,200 Speaker 1: human body. And it's safe to drink this stuff completely. 148 00:07:47,520 --> 00:07:51,160 Speaker 1: They're stable isotopes, so they're non radioactive. But here's what's 149 00:07:51,160 --> 00:07:54,160 Speaker 1: great about them. After somebody drinks d l W that's 150 00:07:54,160 --> 00:07:58,480 Speaker 1: been enriched, researchers suddenly have this tracking mechanism. Basically, by 151 00:07:58,520 --> 00:08:02,360 Speaker 1: measuring the concentration found in urine samples, researchers can determine 152 00:08:02,360 --> 00:08:05,880 Speaker 1: a person's daily rate of carbon dioxide production. And since 153 00:08:05,920 --> 00:08:08,800 Speaker 1: carbon dioxide is a waste product of our bodies energy 154 00:08:08,840 --> 00:08:12,560 Speaker 1: making processes, calculating how much C O two someone produces 155 00:08:12,560 --> 00:08:14,880 Speaker 1: in a day is the best way to measure their 156 00:08:15,000 --> 00:08:18,760 Speaker 1: energy expenditure. That is pretty neat. Yeah, Doubly labeled water 157 00:08:18,840 --> 00:08:21,600 Speaker 1: has become the gold standard for measuring how much energy 158 00:08:21,640 --> 00:08:25,520 Speaker 1: a person consumes. Like, the margin of error is pretty small, 159 00:08:25,840 --> 00:08:28,360 Speaker 1: and in fact, the only downside is the cost. D 160 00:08:28,560 --> 00:08:32,199 Speaker 1: LW is expensive, Like are we talking smart water expensive 161 00:08:32,400 --> 00:08:35,439 Speaker 1: or like Fiji water expensive? No, it's so much more 162 00:08:35,480 --> 00:08:40,959 Speaker 1: than that. Dl W runs researchers about dollars per test subjects. Actually, 163 00:08:41,000 --> 00:08:43,640 Speaker 1: you know what this really expensive water reminds me of? 164 00:08:43,760 --> 00:08:46,000 Speaker 1: And I know that this is totally off topic, but 165 00:08:46,440 --> 00:08:48,439 Speaker 1: did you know that the federal government actually sells a 166 00:08:48,520 --> 00:08:53,199 Speaker 1: two jar of peanut butter and there's just six ounces 167 00:08:53,200 --> 00:08:55,440 Speaker 1: of peanut butter in there. It's like a tiny jar. 168 00:08:56,040 --> 00:08:58,800 Speaker 1: And it also goes by this incredibly catchy name. Are 169 00:08:58,840 --> 00:09:02,640 Speaker 1: you ready for it? Standard Reference Material number two three 170 00:09:02,679 --> 00:09:05,760 Speaker 1: eight of it? Oh? That sounds delicious, But why is 171 00:09:05,760 --> 00:09:08,600 Speaker 1: it actually so expensive? Is it more delicious? No, it's 172 00:09:08,640 --> 00:09:12,240 Speaker 1: the wonkiest reason ever. It's the super precise like peanut butter, 173 00:09:12,360 --> 00:09:16,600 Speaker 1: with specific levels of amino acids and fats and carcinogens. 174 00:09:16,679 --> 00:09:19,719 Speaker 1: And it's mostly used for quality controls so companies can 175 00:09:19,760 --> 00:09:22,800 Speaker 1: test their standards against the governments and make sure it 176 00:09:22,840 --> 00:09:26,079 Speaker 1: measures up. But as a result, no one actually eats 177 00:09:26,080 --> 00:09:29,120 Speaker 1: the peanut butter. It's just for lad purposes, which only 178 00:09:29,120 --> 00:09:31,160 Speaker 1: makes me want to try it more like with a 179 00:09:31,280 --> 00:09:35,319 Speaker 1: really cheap jelly. All right, well, let's get back to D. L. W. 180 00:09:35,480 --> 00:09:37,280 Speaker 1: Let me tell you what herman and his partners were 181 00:09:37,320 --> 00:09:39,559 Speaker 1: actually able to learn from having the Hods of tribe 182 00:09:39,600 --> 00:09:41,960 Speaker 1: drink it. Lay it on me. Well, first, let me 183 00:09:42,000 --> 00:09:44,200 Speaker 1: preface this by saying that the Hods are the kings 184 00:09:44,240 --> 00:09:47,840 Speaker 1: and queens of exercise. Every single day, the men trek 185 00:09:47,960 --> 00:09:50,520 Speaker 1: miles and miles to hunt for game with homemade bows 186 00:09:50,559 --> 00:09:53,840 Speaker 1: and arrows. They scale forty foot trees to hack tree 187 00:09:53,880 --> 00:09:57,160 Speaker 1: limbs with hatchets and gather wild honey. Now, the women 188 00:09:57,240 --> 00:09:59,959 Speaker 1: forage all day for wild berries and other edible plants 189 00:10:00,120 --> 00:10:02,680 Speaker 1: like tubers that they dig out of the ground with sticks. 190 00:10:03,280 --> 00:10:05,360 Speaker 1: Even the kids of the tribe are put to work 191 00:10:05,360 --> 00:10:09,120 Speaker 1: by hauling pails of water from a mile or more away. Okay, 192 00:10:09,160 --> 00:10:12,400 Speaker 1: so they're seriously active and no one sitting at their desks, right, 193 00:10:12,480 --> 00:10:14,880 Speaker 1: definitely not. But what the researchers found was that even 194 00:10:14,880 --> 00:10:18,160 Speaker 1: though the Hadzas lives are far more physically demanding. The 195 00:10:18,200 --> 00:10:20,440 Speaker 1: amount of calories day ate and burned through in the 196 00:10:20,520 --> 00:10:23,640 Speaker 1: day was the same as in Europe and the US. Now, 197 00:10:23,640 --> 00:10:26,439 Speaker 1: the men went through about twenty six hundred calories a 198 00:10:26,559 --> 00:10:30,040 Speaker 1: day and the women burned through about nineteen hundred. According 199 00:10:30,080 --> 00:10:32,760 Speaker 1: to Herman, we looked at the data every way imaginable, 200 00:10:32,800 --> 00:10:36,199 Speaker 1: accounting for the effects of body size, fat percentage, age, 201 00:10:36,280 --> 00:10:39,920 Speaker 1: and sex. No difference at all, which is insane, isn't it. 202 00:10:39,920 --> 00:10:42,880 Speaker 1: I mean that you naturally assume that physically active people 203 00:10:42,920 --> 00:10:45,959 Speaker 1: would burn more calories, of course, but the research really 204 00:10:45,960 --> 00:10:48,400 Speaker 1: doesn't bear that out. In fact, they did a follow 205 00:10:48,480 --> 00:10:51,240 Speaker 1: up study with about three hundred participants and it showed 206 00:10:51,240 --> 00:10:54,079 Speaker 1: the exact same thing. The people who were the most 207 00:10:54,120 --> 00:10:56,800 Speaker 1: active burned the same daily amount of calories as those 208 00:10:56,800 --> 00:11:00,439 Speaker 1: who were only moderately active, and the participants who barely 209 00:11:00,480 --> 00:11:03,280 Speaker 1: left the couch at all burned about two fewer calories 210 00:11:03,280 --> 00:11:05,560 Speaker 1: than them, the same amount they would have burned from 211 00:11:05,559 --> 00:11:08,600 Speaker 1: a mere thirty minutes of exercise. Doesn't seem to suggest 212 00:11:08,640 --> 00:11:12,360 Speaker 1: that our metabolisms are like fixed like. It almost seems 213 00:11:12,400 --> 00:11:14,720 Speaker 1: like there's a preset amount of calories that your body 214 00:11:14,800 --> 00:11:17,719 Speaker 1: is willing to burn in any given day. And no 215 00:11:17,760 --> 00:11:20,360 Speaker 1: matter how far you run or how many push ups 216 00:11:20,400 --> 00:11:22,680 Speaker 1: you do, you won't be able to top that max limit. 217 00:11:23,200 --> 00:11:26,360 Speaker 1: But my bigger question is this, why doesn't the Hadza 218 00:11:26,480 --> 00:11:29,360 Speaker 1: hunter burn more in a day than the average office worker. Well, 219 00:11:29,400 --> 00:11:31,680 Speaker 1: I'm not sure we really have the answer to that yet, 220 00:11:31,720 --> 00:11:34,520 Speaker 1: but one thing I've seen researches suggest is that our 221 00:11:34,520 --> 00:11:37,680 Speaker 1: bodies account for the calories burned through physical activity by 222 00:11:37,760 --> 00:11:40,400 Speaker 1: dialing back on the number of calories we devote to 223 00:11:40,440 --> 00:11:45,120 Speaker 1: the background functions that keep us alive. About six of 224 00:11:45,120 --> 00:11:48,440 Speaker 1: the calories we burn each day go to these unseen 225 00:11:48,640 --> 00:11:52,280 Speaker 1: or unconscious processes, so it's possible that when our physical 226 00:11:52,280 --> 00:11:57,040 Speaker 1: activity pushes us beyond that other of daily cloric expenditure, 227 00:11:57,520 --> 00:11:59,680 Speaker 1: our body is just cut back on the calorie spin 228 00:11:59,720 --> 00:12:02,920 Speaker 1: on tobolic processes. This would help even the scales and 229 00:12:03,000 --> 00:12:05,800 Speaker 1: keep us from exceeding our preset energy budget for the day, 230 00:12:05,920 --> 00:12:10,000 Speaker 1: which is really cool but also disheartening. Right, no wonder, 231 00:12:10,040 --> 00:12:13,959 Speaker 1: I've got this paunch. I feel so betrayed. Don't take 232 00:12:14,000 --> 00:12:17,280 Speaker 1: it too hard. So a fixed daily energy expenditure limit 233 00:12:17,400 --> 00:12:20,000 Speaker 1: is likely, and evolved trade meant to help conserve our 234 00:12:20,040 --> 00:12:23,040 Speaker 1: fat stores for when we really need them. I mean, 235 00:12:23,080 --> 00:12:25,400 Speaker 1: imagine if the Hotsa hunters were free to burn through 236 00:12:25,440 --> 00:12:28,120 Speaker 1: ten thousand calories during a hunt instead of the typical 237 00:12:28,160 --> 00:12:30,520 Speaker 1: two thousand or so, if they were to come up 238 00:12:30,520 --> 00:12:33,120 Speaker 1: empty handed, they would have lost five days worth of 239 00:12:33,200 --> 00:12:37,200 Speaker 1: calories in one with no prospects for replacing them. And 240 00:12:37,240 --> 00:12:39,560 Speaker 1: at that rate they're already limited. Fat stores will be 241 00:12:39,600 --> 00:12:41,840 Speaker 1: depleted in no time, and they'd find themselves on the 242 00:12:41,840 --> 00:12:44,720 Speaker 1: brink of starvation. Which is a great point, but still 243 00:12:44,880 --> 00:12:47,199 Speaker 1: doesn't make you feel like maybe all that time spent 244 00:12:47,280 --> 00:12:50,040 Speaker 1: exercising was I don't know, kind of a waste. Want 245 00:12:50,080 --> 00:12:52,840 Speaker 1: no hold on a second, So don't forget that exercise 246 00:12:52,880 --> 00:12:56,080 Speaker 1: has all kinds of great benefits beyond weight loss. For starters, 247 00:12:56,120 --> 00:12:59,680 Speaker 1: exercises fantastic for your heart and blood vessels. It makes 248 00:12:59,679 --> 00:13:03,559 Speaker 1: your heart contract with greater force and frequency, which increases 249 00:13:03,559 --> 00:13:06,920 Speaker 1: blood flow leads to less artery clogging. There's also plenty 250 00:13:06,960 --> 00:13:09,920 Speaker 1: of evidence that exercise helps reduce the risk of some cancers, 251 00:13:09,920 --> 00:13:13,640 Speaker 1: as well as type two diabetes and cardiovascular disease. But 252 00:13:13,679 --> 00:13:16,760 Speaker 1: one of my favorite benefits of exercise that often goes overlooked. 253 00:13:17,120 --> 00:13:19,480 Speaker 1: Not only does it help strengthen your muscles, it helps 254 00:13:19,480 --> 00:13:23,160 Speaker 1: strengthen your bones too. Just like muscles, bones grow stronger 255 00:13:23,160 --> 00:13:25,440 Speaker 1: when they've been made to carry more weight than normal. 256 00:13:25,800 --> 00:13:28,839 Speaker 1: So your muscles contract during exercise, they apply force to 257 00:13:28,920 --> 00:13:31,800 Speaker 1: the bones that support those parts of the body. The 258 00:13:31,880 --> 00:13:34,679 Speaker 1: added force stimulates the bones and causes them to reinforce 259 00:13:34,720 --> 00:13:37,480 Speaker 1: themselves by building new tissue, which is really cool. But 260 00:13:37,600 --> 00:13:40,000 Speaker 1: you know, Will, I'm pretty sure we'd have to forfeit 261 00:13:40,040 --> 00:13:42,400 Speaker 1: our part time Genius membership cards if we miss the 262 00:13:42,440 --> 00:13:44,760 Speaker 1: chance to talk about some of the more amazing mental 263 00:13:44,800 --> 00:13:49,040 Speaker 1: benefits of exercise, like thanks to Fernando Gomez Pinia, a 264 00:13:49,160 --> 00:13:51,800 Speaker 1: neuro surgery professor at U c l A, we now 265 00:13:51,800 --> 00:13:54,600 Speaker 1: have some firm evidence of that connection. Namely, we know 266 00:13:54,720 --> 00:13:57,520 Speaker 1: that exercise increases the number of certain molecules in the 267 00:13:57,520 --> 00:14:00,719 Speaker 1: brain that are crucial for cognition. Because apple, there's one 268 00:14:00,720 --> 00:14:05,360 Speaker 1: molecule called brain derived neurotrophic factor, or b d NF, 269 00:14:05,640 --> 00:14:08,360 Speaker 1: and that stimulates the growth and survival of brain cells 270 00:14:08,440 --> 00:14:11,800 Speaker 1: and even helps facilitate communication between them. And there have 271 00:14:11,840 --> 00:14:14,360 Speaker 1: been some studies on rats that have shown that physical 272 00:14:14,400 --> 00:14:17,080 Speaker 1: activity boost b d n F levels in the hippocampus, 273 00:14:17,400 --> 00:14:19,360 Speaker 1: which is a part of the brain that's super important 274 00:14:19,400 --> 00:14:22,360 Speaker 1: for learning and even memory function, all right, but how 275 00:14:22,440 --> 00:14:25,120 Speaker 1: exactly does that help the rats? Well, that higher level 276 00:14:25,160 --> 00:14:27,800 Speaker 1: of b d NF actually allowed them to better remember 277 00:14:27,840 --> 00:14:30,720 Speaker 1: how they find their way through underwater mazes, and there 278 00:14:30,760 --> 00:14:33,280 Speaker 1: are tons of studies that suggest that same kind of 279 00:14:33,320 --> 00:14:36,680 Speaker 1: mental improvement from fitness happens in humans as well well. 280 00:14:36,680 --> 00:14:38,920 Speaker 1: A better brain is definitely a nice perk. But there's 281 00:14:38,920 --> 00:14:41,720 Speaker 1: another mental benefit to exercise that I like even more, 282 00:14:41,800 --> 00:14:44,600 Speaker 1: and that's mood enhancement. You probably heard of runners high 283 00:14:44,640 --> 00:14:47,320 Speaker 1: or exercise high, sure, and I've heard of both of those. 284 00:14:47,720 --> 00:14:50,160 Speaker 1: That's the euphoric feeling you get when you're need even 285 00:14:50,200 --> 00:14:52,960 Speaker 1: a strenuous workout, right. And while most people think it's 286 00:14:53,000 --> 00:14:56,440 Speaker 1: caused by endorphins, you know, those dandy neurochemicals that minimize 287 00:14:56,480 --> 00:15:00,200 Speaker 1: pain and stir up feelings of well being, exercise eyes 288 00:15:00,200 --> 00:15:03,240 Speaker 1: are actually do more to neurotransmitters like sarah tonin and 289 00:15:03,320 --> 00:15:06,760 Speaker 1: neuro epinephrin. So our bodies pump more of these throughout 290 00:15:06,760 --> 00:15:10,080 Speaker 1: our nervous systems during workouts, which elevates our mood and 291 00:15:10,120 --> 00:15:13,400 Speaker 1: helps fight back feelings of stress and depression. Okay, so 292 00:15:13,840 --> 00:15:16,000 Speaker 1: maybe our bodies aren't quite the turn coats. That made 293 00:15:16,040 --> 00:15:19,040 Speaker 1: them out to be. But we've definitely been misinformed about 294 00:15:19,080 --> 00:15:21,200 Speaker 1: the role of exercise and weight loss. How do you 295 00:15:21,200 --> 00:15:24,520 Speaker 1: think this misunderstanding got started? And uh, is there really 296 00:15:24,560 --> 00:15:28,160 Speaker 1: no basis for thinking exercises an effective way to lose weight? Well, 297 00:15:28,160 --> 00:15:30,800 Speaker 1: there's are great questions, but before we exhaust ourselves, but 298 00:15:30,840 --> 00:15:32,560 Speaker 1: we check in with our guests for a little quiz. 299 00:15:32,600 --> 00:15:41,880 Speaker 1: Sound so our guest today is partially responsible for our 300 00:15:41,920 --> 00:15:45,240 Speaker 1: interest in today's topic. His research has contributed to a 301 00:15:45,320 --> 00:15:48,720 Speaker 1: much better understanding of the relationship between our daily activity, 302 00:15:48,720 --> 00:15:52,800 Speaker 1: our daily calorie consumption and energy use and calorie burning 303 00:15:52,840 --> 00:15:54,920 Speaker 1: and all of that. And his name just kind of 304 00:15:54,960 --> 00:15:57,280 Speaker 1: sounds like he should have a theory named for him. 305 00:15:57,400 --> 00:16:00,680 Speaker 1: Herman Ponzer welcomed his part time genius. Hi, how you 306 00:16:00,760 --> 00:16:03,920 Speaker 1: doing doing well? Thank you? See what I mean, Manga, 307 00:16:03,880 --> 00:16:06,600 Speaker 1: I mean, can't you just imagine something called the Herman 308 00:16:06,640 --> 00:16:12,640 Speaker 1: Ponser theory of why we're still so freaking fat? Sounds right? Yeah, yeah, 309 00:16:12,640 --> 00:16:15,160 Speaker 1: we'll see if we can make that happen. So all right, Herman, Well, 310 00:16:15,240 --> 00:16:17,800 Speaker 1: let's just start with your research. And Tanzania, I mean, 311 00:16:17,840 --> 00:16:19,920 Speaker 1: which got a lot of attention a few years ago, 312 00:16:20,000 --> 00:16:22,480 Speaker 1: and people are still talking about it. Can you tell 313 00:16:22,560 --> 00:16:24,840 Speaker 1: us why you were studying there and and and just 314 00:16:24,920 --> 00:16:29,120 Speaker 1: let our listeners know about your findings from that research. Sure. Well, 315 00:16:29,120 --> 00:16:32,080 Speaker 1: I'm an evolutionary biologist who's interested in how humans got 316 00:16:32,120 --> 00:16:33,440 Speaker 1: to be the way they are and how the human 317 00:16:33,480 --> 00:16:37,040 Speaker 1: body works from a kind of an evolutionary perspective. Um. 318 00:16:37,080 --> 00:16:41,040 Speaker 1: And of course humans we've all spent the most most 319 00:16:41,080 --> 00:16:44,080 Speaker 1: of our history as hunter gathers. If you go back, 320 00:16:44,120 --> 00:16:46,120 Speaker 1: you know, a couple of thousand years, all of us 321 00:16:46,120 --> 00:16:49,080 Speaker 1: are hunting and gathering, and you know, back two million 322 00:16:49,120 --> 00:16:50,960 Speaker 1: years ago and didnting gathering kind of starts. So we 323 00:16:51,000 --> 00:16:54,440 Speaker 1: have a long evolutionary history of hunting the gathering. Uh. 324 00:16:54,480 --> 00:16:58,240 Speaker 1: Not many populations hunt and gather anymore, um, but that 325 00:16:58,280 --> 00:17:02,280 Speaker 1: makes sort of understanding how their lifestyles and their you know, 326 00:17:02,320 --> 00:17:04,880 Speaker 1: their physiology works all the more important because we think 327 00:17:04,880 --> 00:17:08,240 Speaker 1: it's a really important sort of uh touchstone for understanding 328 00:17:08,240 --> 00:17:11,040 Speaker 1: how our bodies work, even in our weird environments today. 329 00:17:11,520 --> 00:17:14,439 Speaker 1: So in northern Tanzania, there's a population called the Hadza, 330 00:17:14,520 --> 00:17:17,600 Speaker 1: who are one of the last UH populations on Earth 331 00:17:17,680 --> 00:17:21,080 Speaker 1: that are still hunt and gather regularly, so they don't 332 00:17:21,119 --> 00:17:24,959 Speaker 1: have any crops or domesticated animals or vehicles or guns 333 00:17:25,000 --> 00:17:27,560 Speaker 1: or machines or anything like that. They wake up every 334 00:17:27,600 --> 00:17:31,040 Speaker 1: morning and go off and hunt wild game and gather 335 00:17:31,359 --> 00:17:34,160 Speaker 1: wild plant foods, just like you know all of us, 336 00:17:34,200 --> 00:17:38,439 Speaker 1: did you know, just a few generations ago. Uh. And 337 00:17:38,520 --> 00:17:42,480 Speaker 1: so there's this really amazing and cool and generous and 338 00:17:42,480 --> 00:17:45,320 Speaker 1: wonderful population to work with to try to understand how 339 00:17:45,359 --> 00:17:48,560 Speaker 1: that lifestyle affects the way our bodies work. And one 340 00:17:48,560 --> 00:17:50,560 Speaker 1: of the fundamental things we wanted to understand was how 341 00:17:50,600 --> 00:17:52,960 Speaker 1: many calories they burn every day, because we thought, well, 342 00:17:53,000 --> 00:17:55,960 Speaker 1: they're so active. We know they're extremely active, but they've 343 00:17:55,960 --> 00:17:58,960 Speaker 1: burned tons more calories every day than we do here 344 00:17:59,000 --> 00:18:00,800 Speaker 1: in you know, in the US, US and Europe another 345 00:18:00,960 --> 00:18:05,639 Speaker 1: kind of westernized societies. And what we found instead, to 346 00:18:05,720 --> 00:18:08,440 Speaker 1: our huge surprise, was they burned the same number of 347 00:18:08,440 --> 00:18:11,560 Speaker 1: calories every day as you and I do. Wow. So 348 00:18:11,680 --> 00:18:14,960 Speaker 1: if they were wearing a fitbit or something like that, 349 00:18:15,040 --> 00:18:16,840 Speaker 1: would it, I mean, it would tell them that they 350 00:18:16,840 --> 00:18:20,360 Speaker 1: had burned probably thousands more calories than they actually had. 351 00:18:20,480 --> 00:18:22,520 Speaker 1: Is that true? Or you're right, yeah, the fit that 352 00:18:22,560 --> 00:18:25,160 Speaker 1: would tell them the same lies that it tells you, 353 00:18:25,480 --> 00:18:28,840 Speaker 1: which you know, however, active you are, determines how many 354 00:18:28,840 --> 00:18:31,320 Speaker 1: calories you burned. So we know from other studies that 355 00:18:31,320 --> 00:18:35,720 Speaker 1: we've done since that they just to confirm our intuitions there. Uh, 356 00:18:35,760 --> 00:18:37,680 Speaker 1: and this is obvious to anybody who's works with these 357 00:18:37,760 --> 00:18:41,520 Speaker 1: With these folks, Uh, they are incredibly physically active, sort 358 00:18:41,520 --> 00:18:43,880 Speaker 1: of like three to five times more physically active every 359 00:18:43,960 --> 00:18:48,280 Speaker 1: day than the average westerner. Um. And yet despite that, 360 00:18:48,920 --> 00:18:51,040 Speaker 1: they're still burning the same number of calories as we do. 361 00:18:51,320 --> 00:18:53,400 Speaker 1: So you know, they're also really healthy. They have really 362 00:18:53,440 --> 00:18:56,040 Speaker 1: healthy hearts and immune systems. They don't have diabetes or 363 00:18:56,000 --> 00:18:58,119 Speaker 1: anything like that. We think the physical activity is a 364 00:18:58,160 --> 00:19:00,800 Speaker 1: big part of that. So it's important for health, but 365 00:19:00,920 --> 00:19:04,720 Speaker 1: it's not what keeping them, you know, sort of protected 366 00:19:04,720 --> 00:19:07,320 Speaker 1: from obesity. Yeah, and that's a big part of what 367 00:19:07,320 --> 00:19:09,439 Speaker 1: we're trying to remind our listeners of today is just 368 00:19:09,520 --> 00:19:12,439 Speaker 1: because there's not this as strong of a connection as 369 00:19:12,480 --> 00:19:16,080 Speaker 1: we might have thought between exercise and weight loss, they're 370 00:19:16,200 --> 00:19:20,400 Speaker 1: obviously very real benefits to doing the exercise that we do. Yeah, 371 00:19:20,440 --> 00:19:22,040 Speaker 1: that's a really important point because you know, when we 372 00:19:22,080 --> 00:19:23,719 Speaker 1: came out with this study and said, hey, look, these 373 00:19:23,800 --> 00:19:27,760 Speaker 1: hunter gather folks who are important to understand our history 374 00:19:27,800 --> 00:19:31,320 Speaker 1: and and how our bodies work. Um, and we thought 375 00:19:31,320 --> 00:19:32,879 Speaker 1: that they would burn so many work colgies and and 376 00:19:32,960 --> 00:19:36,320 Speaker 1: the rest of us do. Turns out that that's not true. Um. 377 00:19:36,440 --> 00:19:39,880 Speaker 1: The response that we got was, you know, emails from 378 00:19:39,920 --> 00:19:41,720 Speaker 1: out of the blue saying, you know, you're destroying the 379 00:19:41,760 --> 00:19:45,160 Speaker 1: world because you're telling people not to exercise, right, And 380 00:19:45,200 --> 00:19:46,680 Speaker 1: of course that's not what we were saying at all. 381 00:19:46,840 --> 00:19:48,840 Speaker 1: You still to exercise is still important for your health. 382 00:19:48,920 --> 00:19:50,359 Speaker 1: It's just that it doesn't work the way that we 383 00:19:50,600 --> 00:19:52,920 Speaker 1: thought it work, which was the exciting and fun part 384 00:19:52,920 --> 00:19:55,320 Speaker 1: of the science. You know, something that's been puzzling to us. 385 00:19:55,359 --> 00:19:57,919 Speaker 1: And this really isn't related exactly to the HODSA, but 386 00:19:58,640 --> 00:20:01,040 Speaker 1: you know, you remember during previous summer Olympics when you'd 387 00:20:01,080 --> 00:20:03,560 Speaker 1: see all these stories on Michael Phelps and his daily 388 00:20:03,600 --> 00:20:07,720 Speaker 1: diet and Michaels questions. I knew it was exactly So yeah, 389 00:20:07,800 --> 00:20:10,240 Speaker 1: you had to know it was coming. So so just 390 00:20:10,400 --> 00:20:14,880 Speaker 1: I mean, and again of that's that this is called 391 00:20:14,880 --> 00:20:18,600 Speaker 1: the Ponser effect. So, um, so the the insane amount 392 00:20:18,640 --> 00:20:21,400 Speaker 1: of food that he would eat in order to keep 393 00:20:21,480 --> 00:20:24,679 Speaker 1: up with his fitness regiment. I mean, how was he 394 00:20:24,760 --> 00:20:28,360 Speaker 1: not super fat during this process? Yeah? Well, so there's 395 00:20:28,400 --> 00:20:31,240 Speaker 1: two cans. There's at least two pieces of this. One 396 00:20:31,320 --> 00:20:34,920 Speaker 1: is that, um, Michael Phelps is not a normal human 397 00:20:35,600 --> 00:20:38,720 Speaker 1: and uh that's obvious if you watch him swim and 398 00:20:38,760 --> 00:20:42,720 Speaker 1: how fast he is an amazing as he is an athlete. UM. 399 00:20:42,800 --> 00:20:46,360 Speaker 1: And so you know what he's doing during those those 400 00:20:46,800 --> 00:20:49,760 Speaker 1: workout you know cycles where he's burning ten talent colories. 401 00:20:50,320 --> 00:20:53,200 Speaker 1: By the way, actually measured how many calories he's bringing 402 00:20:53,280 --> 00:20:55,560 Speaker 1: during these cycles, So we don't really know. You see 403 00:20:55,600 --> 00:20:58,640 Speaker 1: number thrown around like eight thousand calories a day, um, 404 00:20:58,920 --> 00:21:02,520 Speaker 1: which maybe is to um. We know that if you 405 00:21:02,560 --> 00:21:05,159 Speaker 1: look at like a Tour de France cyclist like is 406 00:21:05,160 --> 00:21:08,000 Speaker 1: happening right now um, or where you look at Michael 407 00:21:08,040 --> 00:21:12,040 Speaker 1: Phelps during or another Olympic athlete during these really intense 408 00:21:12,160 --> 00:21:15,119 Speaker 1: training and competition times that for a few weeks or 409 00:21:15,160 --> 00:21:18,080 Speaker 1: even you know a couple of months, your body can 410 00:21:18,240 --> 00:21:23,320 Speaker 1: burn tons more calories than that would be normal. UM. 411 00:21:23,440 --> 00:21:25,760 Speaker 1: What we don't know is what are the limits to that. 412 00:21:26,280 --> 00:21:28,560 Speaker 1: I don't think Michael Phelps can burn itsels and colors 413 00:21:28,600 --> 00:21:31,720 Speaker 1: to day forever. I think that you know, his body 414 00:21:31,720 --> 00:21:34,720 Speaker 1: would break down. UM. And I think that you know, 415 00:21:34,920 --> 00:21:37,880 Speaker 1: we can do that during certain periods. And the other 416 00:21:37,880 --> 00:21:39,480 Speaker 1: piece of this is that you know, there's a reason 417 00:21:39,480 --> 00:21:41,560 Speaker 1: that not everybody's Michael Phelps, and it might well be 418 00:21:42,240 --> 00:21:45,160 Speaker 1: that people who are flexible enough in their metabolic rate 419 00:21:45,240 --> 00:21:46,920 Speaker 1: to to sort of be able to handle that huge 420 00:21:46,960 --> 00:21:50,880 Speaker 1: influx are the people who end up being Olympic athletes, 421 00:21:51,119 --> 00:21:53,520 Speaker 1: you know. Um. And I think the third thing I'd 422 00:21:53,560 --> 00:21:56,480 Speaker 1: say is it just goes to show you, um, you know, 423 00:21:56,520 --> 00:21:59,760 Speaker 1: we we think of I think sometimes the paleo diet, 424 00:22:00,320 --> 00:22:04,919 Speaker 1: imagine these elite athletes as being kind of indicative of 425 00:22:04,960 --> 00:22:07,520 Speaker 1: what our path was like, right Like if we were 426 00:22:07,560 --> 00:22:10,840 Speaker 1: only if we only exercise like Michael Phelps, we'd all 427 00:22:10,880 --> 00:22:13,720 Speaker 1: be back in this sort of state of nature. Um. 428 00:22:13,760 --> 00:22:16,240 Speaker 1: And in fact, people like Michael Felts are way on 429 00:22:16,320 --> 00:22:19,040 Speaker 1: the extreme of of beyond what's what's normal for any 430 00:22:19,119 --> 00:22:24,120 Speaker 1: human society anywhere. The cycial activity levels extremely too, extremely high. Well, 431 00:22:24,160 --> 00:22:26,040 Speaker 1: I feel like we've been ponsored. So it's time to 432 00:22:26,080 --> 00:22:29,720 Speaker 1: turn the tables here and put into the test. We're 433 00:22:29,720 --> 00:22:31,919 Speaker 1: gonna play a little quiz with herman here. What's our 434 00:22:31,960 --> 00:22:34,679 Speaker 1: quiz called today, Mango, It's called real vintage diet or 435 00:22:34,720 --> 00:22:36,639 Speaker 1: something we just made up all right, So this is 436 00:22:36,640 --> 00:22:38,600 Speaker 1: a pretty simple game. We're going to read you a 437 00:22:38,640 --> 00:22:40,560 Speaker 1: list of diets and you're going to tell us if 438 00:22:40,600 --> 00:22:43,359 Speaker 1: they're real or whether we just made them up.

Um, I'll tell you this. 442 00:22:54,960 --> 00:22:57,560 Speaker 1: A guy ran across the US in two other fift 443 00:22:57,840 --> 00:23:02,480 Speaker 1: drinking almost drinking milk and almost nothing else. So I 444 00:23:02,520 --> 00:23:05,680 Speaker 1: want to say. I want to say true, because full 445 00:23:05,720 --> 00:23:10,400 Speaker 1: a lot of good stuff. Worth that sounds terrible, Yeah, 446 00:23:09,840 --> 00:23:14,159 Speaker 1: it's true. In seventies, pamphlet put off by the California 447 00:23:14,200 --> 00:23:17,639 Speaker 1: Milk Advisory Board advised eating less and drinking milk with 448 00:23:17,680 --> 00:23:20,920 Speaker 1: every meal. Wow, that sounds horrible, and then running it 449 00:23:21,080 --> 00:23:24,160 Speaker 1: just sounds then run across the country. Alright. Number two 450 00:23:24,320 --> 00:23:29,000 Speaker 1: the sexy pineapple diet, which happens to come from Denmark. Um, 451 00:23:29,240 --> 00:23:32,960 Speaker 1: the sexy pineapple diet. I'm gonna say there's no. But 452 00:23:33,119 --> 00:23:35,680 Speaker 1: there's no way. I studied people, and I can tell 453 00:23:35,720 --> 00:23:41,160 Speaker 1: you about people.

And where did this come from. Yeah, Buzzby 456 00:23:48,640 --> 00:23:50,879 Speaker 1: had found this diet book from nineteen seventy and the 457 00:23:51,040 --> 00:23:54,639 Speaker 1: Chicago Tribune it actually reviewed it and they panned it, saying, 458 00:23:54,680 --> 00:23:57,439 Speaker 1: if you're ready to be miserable about something, this diet 459 00:23:57,560 --> 00:24:03,400 Speaker 1: guarantees twenty four hour dismay. Yeah. That so there we go. Alright, 460 00:24:04,359 --> 00:24:08,439 Speaker 1: one out of two. Number three, Chowder through the thirty 461 00:24:08,480 --> 00:24:12,640 Speaker 1: day Chowder, Power diet.

So yes, this is 467 00:24:28,440 --> 00:24:31,720 Speaker 1: this is in fact fault. Right, Yeah, it's false. There 468 00:24:31,800 --> 00:24:33,800 Speaker 1: was a tune around the clock diet for a while. 469 00:24:34,000 --> 00:24:36,320 Speaker 1: Tune around the clock. Alright, So he's two for three. 470 00:24:36,359 --> 00:24:39,880 Speaker 1: Let's see the next one. Skinny like Lincoln the Gettysburg 471 00:24:40,080 --> 00:24:47,040 Speaker 1: ration diet um fault because Lincoln was skinny because he 472 00:24:47,160 --> 00:24:49,879 Speaker 1: was he had a condition. I think I don't think 473 00:24:49,920 --> 00:24:55,040 Speaker 1: he was skinny because I would ate. Yeah, right, So 474 00:24:55,119 --> 00:24:58,000 Speaker 1: the last one here, he's three out of four. The 475 00:24:58,119 --> 00:25:02,800 Speaker 1: drinking Man's diet. Do you have any details on this? 476 00:25:02,920 --> 00:25:07,119 Speaker 1: I mean, what man side? And I got to you 477 00:25:07,119 --> 00:25:10,080 Speaker 1: give me details. It kind of gives it away, doesn't it. Um, 478 00:25:10,119 --> 00:25:15,919 Speaker 1: So so tell me nothing, tell me nothing. True, Absolutely true, 479 00:25:16,359 --> 00:25:19,560 Speaker 1: it's true. I like that. You didn't need any more detail, 480 00:25:19,640 --> 00:25:22,280 Speaker 1: but we'll give you a little. It was subtitled how 481 00:25:22,320 --> 00:25:25,520 Speaker 1: to Lose Weight with Minimum Willpower and it was basically 482 00:25:25,520 --> 00:25:29,639 Speaker 1: in nineteen sixties Atkins Diet. It was based on eating 483 00:25:29,640 --> 00:25:32,160 Speaker 1: steak and drinking nothing but whiskey. All right, well that's 484 00:25:32,160 --> 00:25:35,879 Speaker 1: pretty impressive. So so how's herman done today? Herman did 485 00:25:35,880 --> 00:25:38,920 Speaker 1: an incredible four for five, and in addition to our 486 00:25:39,040 --> 00:25:41,280 Speaker 1: harder than admiration, we're actually gonna send him a copy 487 00:25:41,320 --> 00:25:43,359 Speaker 1: of a book we found called Help Lord the Devil 488 00:25:43,400 --> 00:25:47,800 Speaker 1: Wants Me Fat, a scriptural approach to trim and attractive bodies. 489 00:25:48,280 --> 00:25:50,879 Speaker 1: That's gonna be a great prize. Well, Herman, thanks so 490 00:25:50,920 --> 00:25:53,399 Speaker 1: much for joining us today. Thank you. It was a 491 00:25:53,400 --> 00:26:11,080 Speaker 1: lot of fun. You're listening to part time genius and 492 00:26:11,119 --> 00:26:15,080 Speaker 1: we're talking about the surprising truth behind exercise. So mego. 493 00:26:15,119 --> 00:26:17,159 Speaker 1: Before the break, I was wondering who to blame for 494 00:26:17,200 --> 00:26:19,679 Speaker 1: the fact that exercise has sort of become synonymous with 495 00:26:19,720 --> 00:26:22,240 Speaker 1: weight loss in our minds. Any ideas on that. You're 496 00:26:22,240 --> 00:26:26,679 Speaker 1: asking me to name names, I actually am. Yeah. Well, 497 00:26:26,720 --> 00:26:28,720 Speaker 1: I did some digging, and while it might be a 498 00:26:28,720 --> 00:26:31,720 Speaker 1: little unfair to lay the entire blame for a widespread 499 00:26:31,800 --> 00:26:36,439 Speaker 1: cultural misunderstanding on one individual, there's no denying that John 500 00:26:36,440 --> 00:26:39,359 Speaker 1: Mayor makes a pretty good scapegoat. I'll take it. So 501 00:26:39,480 --> 00:26:42,840 Speaker 1: who is who is John? Mayer? Said? Well, John is 502 00:26:42,880 --> 00:26:46,440 Speaker 1: this French American scientist and nutritionists who did some high 503 00:26:46,440 --> 00:26:50,680 Speaker 1: profile research on the physiology of hunger and metabolism during 504 00:26:50,680 --> 00:26:54,000 Speaker 1: the mid twentieth century. In fact, thanks to his breakthrough 505 00:26:54,080 --> 00:26:57,640 Speaker 1: studies on rats, babies, and school girls in the nineteen fifties, 506 00:26:58,000 --> 00:27:00,919 Speaker 1: Mayor became the first researcher to make a connection between 507 00:27:01,119 --> 00:27:04,520 Speaker 1: exercise and weight loss. He showed that the less physically 508 00:27:04,520 --> 00:27:07,159 Speaker 1: active a person was, the more likely they were to 509 00:27:07,200 --> 00:27:09,240 Speaker 1: be overweight. All right, hold on, so you're saying that 510 00:27:09,359 --> 00:27:12,760 Speaker 1: prior to Mayor, nobody thought that burning calories through exercise 511 00:27:12,840 --> 00:27:15,880 Speaker 1: might result in weight loss. Yeah, it sounds so crazy, 512 00:27:16,000 --> 00:27:18,520 Speaker 1: but that line of thinking was unpopular in the scientific 513 00:27:18,520 --> 00:27:22,920 Speaker 1: community before Mayor came along. In fact, during the nineteen thirties, 514 00:27:22,960 --> 00:27:25,640 Speaker 1: some scientists actually argued that bed rest was the most 515 00:27:25,640 --> 00:27:28,879 Speaker 1: effective way to treat best patients, not exercise. Can you 516 00:27:28,920 --> 00:27:30,960 Speaker 1: imagine this? Aw Are you guys going to hike without me? 517 00:27:31,000 --> 00:27:32,680 Speaker 1: And my doctor says I need to shut a few pounds. 518 00:27:32,680 --> 00:27:35,560 Speaker 1: I'm just gonna lie right here right. It sounds like 519 00:27:35,600 --> 00:27:38,520 Speaker 1: one of those crazy diets or miracle cures you sometimes 520 00:27:38,600 --> 00:27:42,560 Speaker 1: hear about that you know, never actually works. But back 521 00:27:42,600 --> 00:27:45,400 Speaker 1: to Mayor. He actually served as an advisor to both 522 00:27:45,440 --> 00:27:48,040 Speaker 1: the White House and to the w h O, which 523 00:27:48,080 --> 00:27:50,200 Speaker 1: made him a top name in nutrition and one of 524 00:27:50,240 --> 00:27:53,280 Speaker 1: the most influential figures in the public health sphere thanks 525 00:27:53,320 --> 00:27:55,960 Speaker 1: to the connections he made between exercise and weight loss. 526 00:27:56,280 --> 00:27:58,520 Speaker 1: The idea of getting fit took off in the sixties 527 00:27:58,520 --> 00:28:02,840 Speaker 1: and seventies, which led to this uh thriving gym industry 528 00:28:02,920 --> 00:28:05,240 Speaker 1: in a cultural obsession with working out as a way 529 00:28:05,280 --> 00:28:08,280 Speaker 1: to lose weight and to live healthier, and it clearly 530 00:28:08,280 --> 00:28:11,560 Speaker 1: snowballed from their Obesity rates have risen dramatically over the 531 00:28:11,640 --> 00:28:14,119 Speaker 1: last few decades as more and more of the population 532 00:28:14,160 --> 00:28:17,320 Speaker 1: began trading jobs on farms and in factories for these 533 00:28:17,320 --> 00:28:20,439 Speaker 1: desk jobs. It probably made sense to conclude that this 534 00:28:20,520 --> 00:28:23,880 Speaker 1: more sedentary lifestyle was the cause of all that weight gain, right, 535 00:28:23,960 --> 00:28:27,200 Speaker 1: But today's scientists, no, that's not the full story. It's 536 00:28:27,200 --> 00:28:29,879 Speaker 1: actually a case of mixing up cause and effect. People 537 00:28:29,920 --> 00:28:33,560 Speaker 1: aren't overweight because they're inactive. They're inactive because they're overweight. 538 00:28:33,880 --> 00:28:35,919 Speaker 1: It's harder to stay active when you weigh more, so 539 00:28:36,240 --> 00:28:38,440 Speaker 1: many people just don't. Well, it makes sense because it 540 00:28:38,480 --> 00:28:41,480 Speaker 1: points back to the real culprit behind the obesity epidemic, 541 00:28:41,520 --> 00:28:44,680 Speaker 1: and that's diet. We really have an obscene amount of 542 00:28:44,680 --> 00:28:47,280 Speaker 1: food options today, and thanks to lifestyles that are more 543 00:28:47,320 --> 00:28:51,360 Speaker 1: sedentary compared to previous generations, we have plenty of opportunities 544 00:28:51,400 --> 00:28:54,360 Speaker 1: to over indulge on all of that variety, and we 545 00:28:54,480 --> 00:28:57,960 Speaker 1: take full advantage of this. For instance, researchers at Harvard 546 00:28:58,000 --> 00:29:01,160 Speaker 1: conducted to surveys on food consume. One was in the 547 00:29:01,160 --> 00:29:03,600 Speaker 1: mid nineteen seventies and then a second in the mid 548 00:29:03,680 --> 00:29:06,240 Speaker 1: nine nineties, and they found that although the number of 549 00:29:06,280 --> 00:29:09,440 Speaker 1: calories expended didn't change significantly in that time period, the 550 00:29:09,520 --> 00:29:12,120 Speaker 1: number of calories consumed in a day increased by two 551 00:29:12,240 --> 00:29:15,040 Speaker 1: hundred and sixty eight calories for men and a hundred 552 00:29:15,040 --> 00:29:17,480 Speaker 1: and forty three for women. Yeah, it really does sound 553 00:29:17,560 --> 00:29:21,200 Speaker 1: like our unfettered access to affordable, no muss prepared foods 554 00:29:21,240 --> 00:29:24,320 Speaker 1: has taken a toll on our waistlines. I mean, we're 555 00:29:24,400 --> 00:29:29,160 Speaker 1: constantly surrounded by food, and according to Brian wantsonk uh Cornell, 556 00:29:29,280 --> 00:29:32,080 Speaker 1: researcher who studies how we eat, we eat the amount 557 00:29:32,120 --> 00:29:34,320 Speaker 1: of food we do mostly because of what's around us. 558 00:29:34,760 --> 00:29:38,480 Speaker 1: In his book Mindless Eating, Brian writes, we overeat not 559 00:29:38,560 --> 00:29:41,880 Speaker 1: because of hunger, but because of family and friends, packages 560 00:29:41,920 --> 00:29:46,120 Speaker 1: and plates, names and numbers, labels and lights, colors and candles, 561 00:29:46,160 --> 00:29:50,600 Speaker 1: shapes and smells, distractions and distances, cupboards and containers. This 562 00:29:50,640 --> 00:29:53,480 Speaker 1: list is almost as endless as it's invisible. I think 563 00:29:53,520 --> 00:29:57,040 Speaker 1: he was just showing off his illiterative ability. That was impressive. 564 00:29:57,680 --> 00:29:59,960 Speaker 1: So it's not so much that are less active lifestyle 565 00:30:00,080 --> 00:30:02,080 Speaker 1: have made us gain weight, but that we've developed a 566 00:30:02,120 --> 00:30:05,280 Speaker 1: bad habit of filling that downtime with mindless eating brought 567 00:30:05,280 --> 00:30:08,280 Speaker 1: on by food cues. Exactly. It's the reverse principle of 568 00:30:08,320 --> 00:30:11,200 Speaker 1: out of sight, out of mind. Brian calls it insight 569 00:30:11,320 --> 00:30:14,200 Speaker 1: in stomach creative. This guy is just full of them, 570 00:30:14,240 --> 00:30:17,040 Speaker 1: and it's a serious problem. For example, if you have 571 00:30:17,080 --> 00:30:19,400 Speaker 1: cookies or chips sitting out on your counter, there's a 572 00:30:19,440 --> 00:30:22,040 Speaker 1: strong chance you'll weigh about eight pounds more than a 573 00:30:22,040 --> 00:30:25,120 Speaker 1: person who doesn't. Oh wow, we really are that suggestible, 574 00:30:25,120 --> 00:30:27,880 Speaker 1: aren't we. Yeah, and it gets much worse. Soda is 575 00:30:27,880 --> 00:30:29,800 Speaker 1: one of the big examples that gets brought up as 576 00:30:29,840 --> 00:30:33,160 Speaker 1: a contributor to rising ob CD rates, and it looks 577 00:30:33,200 --> 00:30:35,479 Speaker 1: like that's for a good reason. Apparently, if you keep 578 00:30:35,560 --> 00:30:38,320 Speaker 1: soda on hand in plain sight, like front and center 579 00:30:38,360 --> 00:30:42,080 Speaker 1: in your fridge, you're gonna weigh on average twenty pounds 580 00:30:42,120 --> 00:30:44,240 Speaker 1: more than a person who doesn't. Okay, you're just scaring 581 00:30:44,240 --> 00:30:46,720 Speaker 1: me now, My god. So we've got to figure out 582 00:30:46,720 --> 00:30:48,280 Speaker 1: a way to keep our weight in check. And it's 583 00:30:48,320 --> 00:30:51,800 Speaker 1: clear now that exercise alone isn't going to cut it. Still, 584 00:30:51,840 --> 00:30:54,080 Speaker 1: I don't want to write off weight loss through exercise 585 00:30:54,160 --> 00:30:57,160 Speaker 1: completely like the nineteen thirties type. So let's try to 586 00:30:57,200 --> 00:31:00,280 Speaker 1: make sense of how to really maximize its benefits. Great, 587 00:31:00,400 --> 00:31:02,840 Speaker 1: but before we get into that, let's break for a quiz. 588 00:31:12,120 --> 00:31:15,160 Speaker 1: Welcome back to part time Genius. So here we are mango, 589 00:31:15,440 --> 00:31:20,640 Speaker 1: four chiseled bodies all in one room, or rather rather, 590 00:31:20,760 --> 00:31:24,520 Speaker 1: two personal trainers and two podcasters. I think yeah, but 591 00:31:24,520 --> 00:31:28,200 Speaker 1: there's a twelve tip between the fourmus I'm with you 592 00:31:28,280 --> 00:31:30,120 Speaker 1: on that. So, so who do we have us with 593 00:31:30,200 --> 00:31:33,200 Speaker 1: us in studio today? Mango, We've got Jenet words and 594 00:31:33,320 --> 00:31:36,400 Speaker 1: Mario Jordan's from the form Athletic Club in Pont City 595 00:31:36,400 --> 00:31:39,280 Speaker 1: Market right here in Atlanta. That is just right downstairs 596 00:31:39,320 --> 00:31:41,960 Speaker 1: from us. So welcome guys, thanks for having us having us. 597 00:31:42,040 --> 00:31:44,680 Speaker 1: All right, So we were just talking before before we 598 00:31:44,720 --> 00:31:47,160 Speaker 1: started out that, Mario, you were telling us a little 599 00:31:47,160 --> 00:31:50,040 Speaker 1: bit about your your breakfast regiment every single day. What 600 00:31:50,120 --> 00:31:54,400 Speaker 1: is it that usually? Um, it's basically two cups of 601 00:31:54,400 --> 00:32:02,080 Speaker 1: old meal and six hard boarding me. So say, okay, 602 00:32:02,080 --> 00:32:03,760 Speaker 1: hard ball. You didn't say that before because I was 603 00:32:03,760 --> 00:32:07,040 Speaker 1: gonna ask if we're doing this like Rocky? So no, no, yeah, 604 00:32:07,520 --> 00:32:11,080 Speaker 1: have you have you ever done that? Can't do it? Okay, 605 00:32:11,120 --> 00:32:14,360 Speaker 1: it's horrible. I don't do scrambled eggs or yeah, you're 606 00:32:14,400 --> 00:32:17,320 Speaker 1: just always horrible. How about you, Janee? Do you how 607 00:32:17,360 --> 00:32:20,760 Speaker 1: many do you have? Eight eggs? Oh? No, probably throughout 608 00:32:20,800 --> 00:32:23,840 Speaker 1: the day I could, but um, generally I'll have about 609 00:32:23,920 --> 00:32:27,920 Speaker 1: four egg whites, sometimes one whole egg and either protein 610 00:32:28,000 --> 00:32:32,120 Speaker 1: pancake or ezekiel bread oatmeal. It just takes so long 611 00:32:32,240 --> 00:32:34,560 Speaker 1: to eat for me, so I really don't know how 612 00:32:34,600 --> 00:32:39,440 Speaker 1: Mario gets through. And actually, with the hard boiled eggs, 613 00:32:39,480 --> 00:32:41,160 Speaker 1: I have this problem where I used to when I 614 00:32:41,160 --> 00:32:42,959 Speaker 1: would travel a lot and I would stop in and 615 00:32:43,000 --> 00:32:45,080 Speaker 1: grab a couple of hard boiled eggs real quick, and 616 00:32:45,080 --> 00:32:47,840 Speaker 1: I would eat them too fast, and I just knew 617 00:32:47,840 --> 00:32:49,960 Speaker 1: that I was dying because I couldn't breathe, like you're 618 00:32:50,080 --> 00:32:52,760 Speaker 1: choking up because they're so dry. Does that ever happen 619 00:32:52,760 --> 00:32:56,400 Speaker 1: to you? Sometimes? Most of them. I mean it depends 620 00:32:56,440 --> 00:32:58,480 Speaker 1: on how long you cook it. Something just overcooked and 621 00:32:58,560 --> 00:33:07,960 Speaker 1: it will it'll be dry. Ye. This actually speaks to 622 00:33:08,000 --> 00:33:11,800 Speaker 1: what we've been talking about today. That is important as exercises. Clearly, 623 00:33:11,920 --> 00:33:14,000 Speaker 1: diet is very important. That's why these two are in 624 00:33:14,080 --> 00:33:16,520 Speaker 1: such great shape because they're not exactly slacky. Now do 625 00:33:16,560 --> 00:33:19,400 Speaker 1: you guys have your cheat days or how does that 626 00:33:19,440 --> 00:33:22,600 Speaker 1: work for you? Guys? Um? For me, I prep my 627 00:33:22,680 --> 00:33:26,240 Speaker 1: food um pretty much weekly, whether it's for seven days 628 00:33:26,360 --> 00:33:29,240 Speaker 1: or three days. And then yes, I do cheat. I'm human. 629 00:33:29,360 --> 00:33:32,040 Speaker 1: I actually work out and eat right, so I can't 630 00:33:32,040 --> 00:33:34,200 Speaker 1: eat it like that's one of the things I do. 631 00:33:34,280 --> 00:33:38,120 Speaker 1: So yes, okay, how about you? I'm the same way. Um, 632 00:33:38,320 --> 00:33:44,040 Speaker 1: I have cheap meals here and there that Doritos locos, Uh, 633 00:33:44,480 --> 00:33:49,280 Speaker 1: milkshakes from Chick fil A good, Those are insane.

They're so good at this, all right, 669 00:35:43,280 --> 00:35:45,960 Speaker 1: it is something we made up. Mangoes a threat on this. 670 00:35:46,000 --> 00:35:47,719 Speaker 1: He's pretty good at making these things up, all right. 671 00:35:47,840 --> 00:35:51,320 Speaker 1: Number three, this is back to you, Janet.

Is 675 00:36:01,880 --> 00:36:04,400 Speaker 1: this a real exercise fat or something we made up? 676 00:36:04,920 --> 00:36:07,439 Speaker 1: I was trying to visualize it, and I couldn't even 677 00:36:07,520 --> 00:36:10,920 Speaker 1: visualize that, So I'm gonna say it's made up. We 678 00:36:11,000 --> 00:36:14,920 Speaker 1: finally have a wrong answer. They're not perfect. This is 679 00:36:14,920 --> 00:36:18,279 Speaker 1: a real exercise fat and super bizarre to see a 680 00:36:18,320 --> 00:36:21,799 Speaker 1: picture of this. Number four, Mario, this was back to 681 00:36:21,840 --> 00:36:25,920 Speaker 1: you air shorts great for shedding body moisture. These versatile, 682 00:36:25,960 --> 00:36:29,839 Speaker 1: inflatable shorts were supposed to bake your stomach, thighs, and bottom, 683 00:36:29,880 --> 00:36:32,360 Speaker 1: causing you to sweat as you worked out or wandered 684 00:36:32,400 --> 00:36:36,400 Speaker 1: about town. Is this a real exercise fad or something 685 00:36:36,520 --> 00:36:42,520 Speaker 1: we made up? Uh? As ridiculous as it sounds, let's 686 00:36:42,520 --> 00:36:49,800 Speaker 1: say it's real. Look ridiculous. The pressure is on. Okay, 687 00:36:50,520 --> 00:36:52,800 Speaker 1: I think this is a two pointer, though if I'm mistaken, 688 00:36:52,840 --> 00:36:55,239 Speaker 1: if I'm reading the rules correctly, the official rules of 689 00:36:55,239 --> 00:36:58,839 Speaker 1: our game here, Okay, tag suit the it new way 690 00:36:58,920 --> 00:37:01,400 Speaker 1: to weight loss, A weighted suit you can wear as 691 00:37:01,440 --> 00:37:04,640 Speaker 1: you run around playing adult tag with your friends. Just 692 00:37:04,760 --> 00:37:08,120 Speaker 1: don't stay on base. Is this a real fat or 693 00:37:08,200 --> 00:37:15,759 Speaker 1: something we made up? A real thing? Oh no, it's 694 00:37:15,760 --> 00:37:18,360 Speaker 1: equipment we made off. She didn't see as I was 695 00:37:18,400 --> 00:37:21,920 Speaker 1: trying to make eye contact. All right, here we go. 696 00:37:22,600 --> 00:37:25,120 Speaker 1: Now this one, actually, unfortunately Mario comes with a penalty 697 00:37:25,120 --> 00:37:27,279 Speaker 1: if you miss it of negative one. So let's see. 698 00:37:27,320 --> 00:37:31,759 Speaker 1: So the pressure is on the game. One last one. 699 00:37:31,840 --> 00:37:35,800 Speaker 1: This one is called Twist in Tone, the exerciser that's fun, 700 00:37:35,920 --> 00:37:39,400 Speaker 1: easy and works. Basically, it was a plastic lazy Susan 701 00:37:39,600 --> 00:37:42,560 Speaker 1: that you could stand on while doing the twist. Totally 702 00:37:42,560 --> 00:37:46,840 Speaker 1: worth the five dollars and cents. Real fat or something 703 00:37:46,920 --> 00:37:56,680 Speaker 1: we made up? It's real? Oh I remember seeing something 704 00:37:56,719 --> 00:37:59,440 Speaker 1: like that on TV. Oh wow. All right, we'll tell 705 00:37:59,520 --> 00:38:01,359 Speaker 1: us how our can testants have done here today, Mango 706 00:38:01,600 --> 00:38:04,440 Speaker 1: Well as always, first place wins a handwritten note from 707 00:38:04,520 --> 00:38:07,440 Speaker 1: us to your mom or boss, singing your praises. So Mario, 708 00:38:07,640 --> 00:38:10,280 Speaker 1: that's coming your way. And because we don't want anyone 709 00:38:10,320 --> 00:38:12,880 Speaker 1: going home empty handed, Janet, you're getting a pair of 710 00:38:12,920 --> 00:38:16,040 Speaker 1: hander pants, the number one underwear inspired gloves on the 711 00:38:16,080 --> 00:38:22,399 Speaker 1: market today. Well, thank you guys, so much for joining 712 00:38:22,440 --> 00:38:24,799 Speaker 1: us today on part time Genius. Thank you for having us. 713 00:38:39,400 --> 00:38:41,719 Speaker 1: So we were talking before about how we've been conditioned 714 00:38:41,719 --> 00:38:44,759 Speaker 1: over the last fifty years or so to associate exercise 715 00:38:44,880 --> 00:38:46,759 Speaker 1: with weight loss and what has turned out to be 716 00:38:46,800 --> 00:38:49,680 Speaker 1: a fairly unhealthy way. Yeah. I mean, a lot of 717 00:38:49,719 --> 00:38:52,360 Speaker 1: people start workout routines because they expect the pounds to 718 00:38:52,480 --> 00:38:55,319 Speaker 1: just melt off based on everything we've been told about 719 00:38:55,320 --> 00:38:57,719 Speaker 1: how to stay fit. But when that doesn't happen as 720 00:38:57,800 --> 00:39:00,880 Speaker 1: much as we expect, and the payoffs seems too slow 721 00:39:01,120 --> 00:39:03,239 Speaker 1: or too little for the amount of effort, well, then 722 00:39:03,239 --> 00:39:06,160 Speaker 1: it's good body or gym membership exactly. And that's the 723 00:39:06,200 --> 00:39:09,120 Speaker 1: real shame. So many of us put unhealthy pressure on 724 00:39:09,120 --> 00:39:12,719 Speaker 1: ourselves as a result of these unrealistic expectations that we 725 00:39:12,760 --> 00:39:15,479 Speaker 1: put on an exercise, and the end result is often 726 00:39:15,480 --> 00:39:17,799 Speaker 1: that we blame ourselves and just give up on losing 727 00:39:17,840 --> 00:39:20,520 Speaker 1: weight altogether. And that also causes us to miss out 728 00:39:20,520 --> 00:39:24,000 Speaker 1: on the very real mental and physical benefits of regular exercise. 729 00:39:24,440 --> 00:39:26,520 Speaker 1: So let's try to help avoid that, Mango. Let's put 730 00:39:26,560 --> 00:39:30,959 Speaker 1: the true effectiveness of exercise for weight loss into perspective. Okay, Well, 731 00:39:31,320 --> 00:39:33,239 Speaker 1: first off, I think we should say that the main 732 00:39:33,280 --> 00:39:35,680 Speaker 1: reason why a lot of people's exercise routines go could 733 00:39:35,680 --> 00:39:38,600 Speaker 1: put is the same reason why sixty of diet or 734 00:39:38,680 --> 00:39:41,560 Speaker 1: is returned to their original weight within three years, As 735 00:39:41,640 --> 00:39:45,840 Speaker 1: diet and behavior expert Charlotte Markey told Scientific American, people 736 00:39:45,920 --> 00:39:48,680 Speaker 1: think too much about short term goals and don't think 737 00:39:48,800 --> 00:39:52,040 Speaker 1: enough about sustainable changes. If you're going to lose weight, 738 00:39:52,080 --> 00:39:53,920 Speaker 1: you have to change your behaviors for the rest of 739 00:39:53,960 --> 00:39:56,640 Speaker 1: your life for otherwise you gain it back. And that's 740 00:39:56,680 --> 00:39:59,680 Speaker 1: not a sexy message because it seems daunting. Yeah, it does. 741 00:39:59,800 --> 00:40:01,680 Speaker 1: And does she have any suggestions on what kind of 742 00:40:01,719 --> 00:40:05,239 Speaker 1: lifelong behavioral changes people might actually be able to stomach. Yeah, 743 00:40:05,280 --> 00:40:08,360 Speaker 1: it's all about sustainability. So for example, people don't have 744 00:40:08,400 --> 00:40:11,240 Speaker 1: to completely cut out entire food groups or ice cream 745 00:40:11,360 --> 00:40:13,959 Speaker 1: or anything like that. But we should strive for small 746 00:40:14,000 --> 00:40:17,280 Speaker 1: scale changes that we stick to, like dropping a soda 747 00:40:17,360 --> 00:40:19,200 Speaker 1: or two from our daily diet so we can cut 748 00:40:19,200 --> 00:40:22,120 Speaker 1: a few hundred calories from our intake, or staying on 749 00:40:22,160 --> 00:40:24,839 Speaker 1: the lookout to avoid mindless eating. Well, I think that's 750 00:40:24,840 --> 00:40:27,120 Speaker 1: the kind of sustainability is what we should aim for 751 00:40:27,239 --> 00:40:29,919 Speaker 1: with exercise too. I mean, once you stop thinking about 752 00:40:29,960 --> 00:40:32,520 Speaker 1: the physical activity primarily is a way to lose weight. 753 00:40:33,000 --> 00:40:35,640 Speaker 1: It frees us up to add exercise into our routines 754 00:40:35,680 --> 00:40:38,040 Speaker 1: and enjoyable ways that will be less likely to give 755 00:40:38,160 --> 00:40:41,080 Speaker 1: up on totally. And despite all we've learned about the 756 00:40:41,080 --> 00:40:44,440 Speaker 1: limitations of calorie burning through workouts, there actually are some 757 00:40:44,440 --> 00:40:47,040 Speaker 1: ways to use exercise to help us with our weight 758 00:40:47,080 --> 00:40:50,200 Speaker 1: loss efforts like what. Well, for one thing, exercise helps 759 00:40:50,239 --> 00:40:53,120 Speaker 1: distract us from our food cravings. It gives people something 760 00:40:53,120 --> 00:40:56,040 Speaker 1: else to concentrate on, and there are some forms of 761 00:40:56,080 --> 00:40:58,480 Speaker 1: exercise that can help maximize the amount of weight you 762 00:40:58,520 --> 00:41:01,319 Speaker 1: lose from fat rather than must. Well that's a good point. 763 00:41:01,400 --> 00:41:04,320 Speaker 1: So we've mostly been talking about exercise in broad terms, 764 00:41:04,320 --> 00:41:07,120 Speaker 1: but it's worth mentioning that most forms of exercise fall 765 00:41:07,160 --> 00:41:10,840 Speaker 1: into one of two broad groups. So we've got aerobic 766 00:41:10,880 --> 00:41:15,160 Speaker 1: type exercise like running, biking, swimming, rowing, etcetera, which helps 767 00:41:15,200 --> 00:41:18,880 Speaker 1: strengthen your heart and build stamina, and then anaerobic exercise 768 00:41:18,920 --> 00:41:22,719 Speaker 1: such as weightlifting or sprinting, which helps increase lean muscle mass. Right, 769 00:41:22,800 --> 00:41:26,040 Speaker 1: and both types of workout will burn fat and help 770 00:41:26,040 --> 00:41:28,360 Speaker 1: you lose a little weight, but studies have found that 771 00:41:28,400 --> 00:41:31,479 Speaker 1: aerobic training does provide the advantage in terms of most 772 00:41:31,520 --> 00:41:33,719 Speaker 1: weight and fat burned. So if you're looking for the 773 00:41:33,719 --> 00:41:35,680 Speaker 1: best way to burn the most fat and the least 774 00:41:35,719 --> 00:41:39,160 Speaker 1: amount of time, aerobic exercises probably the way to go. 775 00:41:39,400 --> 00:41:41,279 Speaker 1: That's true, but I wouldn't trade in your barbells for 776 00:41:41,360 --> 00:41:44,760 Speaker 1: running shoes just yet. If sustainability really is the goal, 777 00:41:45,239 --> 00:41:47,760 Speaker 1: it's not a bad idea to gain some extra lean muscle. 778 00:41:48,280 --> 00:41:50,720 Speaker 1: The research shows that an increase in muscle can speed 779 00:41:50,800 --> 00:41:53,960 Speaker 1: up your resting metabolic rate, plus booster strength, and even 780 00:41:54,040 --> 00:41:56,600 Speaker 1: lead to a better night's sleep. So if you're really 781 00:41:56,640 --> 00:41:58,880 Speaker 1: in it for the long haul, the best strategy is 782 00:41:58,920 --> 00:42:00,920 Speaker 1: probably do a little bit of both, which sounds like 783 00:42:00,920 --> 00:42:03,640 Speaker 1: a smart plan. Another thing I always wonder about is 784 00:42:03,719 --> 00:42:07,320 Speaker 1: fitness trackers like garments and Tom Tom's and fit fits. 785 00:42:07,880 --> 00:42:10,880 Speaker 1: Lots of people swear by them, and they're everywhere nowadays. 786 00:42:10,960 --> 00:42:13,359 Speaker 1: Like I even saw that McDonald's was giving them away 787 00:42:13,360 --> 00:42:15,759 Speaker 1: in happy Meals last year and what had to have have 788 00:42:15,800 --> 00:42:19,960 Speaker 1: been one of the most ironic promotions. Articulous. So everybody 789 00:42:20,000 --> 00:42:22,040 Speaker 1: has these things draped to their risk, But did they 790 00:42:22,120 --> 00:42:25,279 Speaker 1: really help us lose weight or the com any healthier. Well, 791 00:42:25,320 --> 00:42:27,840 Speaker 1: you know, we recently had a listener ask a similar question. 792 00:42:27,920 --> 00:42:30,800 Speaker 1: So I did some digging and it turns out not really. 793 00:42:31,239 --> 00:42:33,280 Speaker 1: I mean, there isn't a ton of long term research 794 00:42:33,360 --> 00:42:36,719 Speaker 1: yet on the effects of wearable fitness technology. It hasn't 795 00:42:36,800 --> 00:42:39,360 Speaker 1: yet been around long enough. But most of the short 796 00:42:39,440 --> 00:42:42,560 Speaker 1: term studies have found that wearing fitness trackers only lead 797 00:42:42,600 --> 00:42:46,040 Speaker 1: to a small boost and physical activity, not nearly enough 798 00:42:46,080 --> 00:42:49,440 Speaker 1: to lead to any improvements in overall health. And what's worse, 799 00:42:49,800 --> 00:42:51,920 Speaker 1: one study found that when people were given the option 800 00:42:51,960 --> 00:42:54,640 Speaker 1: of wearing a fitness tracker or not, the people who 801 00:42:54,760 --> 00:42:57,439 Speaker 1: chose to wear it actually lost less weight than those 802 00:42:57,440 --> 00:43:00,360 Speaker 1: who didn't know. It was seven point seven pounds compared 803 00:43:00,400 --> 00:43:03,520 Speaker 1: to the thirteen pounds of those who went techless, which 804 00:43:03,520 --> 00:43:06,600 Speaker 1: isn't exactly a bringing endorsement, no, but it's not completely 805 00:43:06,640 --> 00:43:09,000 Speaker 1: a lost cause. I mean, keeping track of steps and 806 00:43:09,040 --> 00:43:12,240 Speaker 1: calories can be a useful motivator for some folks, provided 807 00:43:12,280 --> 00:43:15,280 Speaker 1: they don't take that success as an excuse to reward 808 00:43:15,320 --> 00:43:18,839 Speaker 1: themselves with their extra large pizza. Right, and uh, we've 809 00:43:18,880 --> 00:43:21,800 Speaker 1: seen how that goes, right, So, fitness trackers can definitely 810 00:43:22,000 --> 00:43:24,279 Speaker 1: be a helpful weapon in the never ending battle of 811 00:43:24,320 --> 00:43:27,480 Speaker 1: the bulge. But just like exercise or dieting, there no 812 00:43:27,560 --> 00:43:30,560 Speaker 1: guarantee of weight loss on their own. Well. I don't 813 00:43:30,560 --> 00:43:32,960 Speaker 1: know about you will, but all this talk about exercise 814 00:43:32,960 --> 00:43:35,680 Speaker 1: has me feeling a little competitive. Where do you say 815 00:43:35,719 --> 00:43:37,320 Speaker 1: we go toe to toe in the part time genius? 816 00:43:37,480 --> 00:43:52,040 Speaker 1: All right, I'm ready when you are a mango. M alright. 817 00:43:52,040 --> 00:43:53,960 Speaker 1: So here's a tip that comes straight from one of 818 00:43:54,000 --> 00:43:59,480 Speaker 1: America's favorite fitness gurus, Barbie. In slumber Party, Barbie came 819 00:43:59,520 --> 00:44:01,880 Speaker 1: to your play with a diet book in hand, and 820 00:44:01,960 --> 00:44:05,959 Speaker 1: the only tip in it don't eat terrible. Uh though, 821 00:44:06,160 --> 00:44:09,440 Speaker 1: here's one that's even worse, the tapeworm diet. Back in 822 00:44:09,480 --> 00:44:12,560 Speaker 1: the early twentieth century, diet pills filled with tapeworms were 823 00:44:12,600 --> 00:44:14,600 Speaker 1: sold over the counter with the promise that you could 824 00:44:14,640 --> 00:44:17,440 Speaker 1: eat more and still lose weight. And of course, when 825 00:44:17,480 --> 00:44:20,240 Speaker 1: the baby tapeworms grew up to be like these twenty 826 00:44:20,320 --> 00:44:24,120 Speaker 1: five foot monstrosities and started causing things like meningitis and 827 00:44:24,200 --> 00:44:26,919 Speaker 1: dimension in their hosts, the government decided that the weight 828 00:44:26,960 --> 00:44:29,760 Speaker 1: loss through worms was overrated and the band the pills. 829 00:44:30,360 --> 00:44:32,279 Speaker 1: Diet coke might not be that much better for you 830 00:44:32,280 --> 00:44:35,560 Speaker 1: than regular coke, but it certainly is lighter. While I 831 00:44:35,600 --> 00:44:37,920 Speaker 1: can of coke will sink in water, you know, kind 832 00:44:37,920 --> 00:44:41,400 Speaker 1: of like a bulldog. Diet coke actually floats more like 833 00:44:41,440 --> 00:44:45,359 Speaker 1: a hot dog. I'm glad you put the dog just 834 00:44:45,400 --> 00:44:49,640 Speaker 1: really helps you understand what floating is. My favorite exercise 835 00:44:49,640 --> 00:44:52,799 Speaker 1: item from the seventies is the Sauna exercise suit, which 836 00:44:52,840 --> 00:44:55,680 Speaker 1: looks nothing like a suit. It's more like a tinfoil 837 00:44:55,719 --> 00:44:59,279 Speaker 1: and marshmallow man contraption that promised to help you shed 838 00:44:59,320 --> 00:45:02,880 Speaker 1: pounds as you us went about your daily business. Calvin 839 00:45:02,920 --> 00:45:06,280 Speaker 1: Coolige's main exercise in the office was through an electric horse, 840 00:45:06,560 --> 00:45:09,320 Speaker 1: kind of like a mechanical bull. He'd write it three 841 00:45:09,360 --> 00:45:12,400 Speaker 1: times a day on various settings, from saunter to gallop, 842 00:45:13,000 --> 00:45:15,239 Speaker 1: but the regiment sounded so silly he kept it a 843 00:45:15,320 --> 00:45:18,080 Speaker 1: secret until it accidentally bucked him from the saddle and 844 00:45:18,160 --> 00:45:21,600 Speaker 1: had to be put down by an electrician. So that's 845 00:45:21,640 --> 00:45:25,080 Speaker 1: pretty good. But here's a great tip from the seventeen hundreds. 846 00:45:25,480 --> 00:45:28,239 Speaker 1: If you want to lose weight, stay away from swamps. 847 00:45:29,000 --> 00:45:32,880 Speaker 1: In seventeen seven, a so called scientist named Thomas Short 848 00:45:32,920 --> 00:45:35,960 Speaker 1: observed that beast people seemed to live near swamps, so 849 00:45:36,000 --> 00:45:39,360 Speaker 1: it was important work on the matter, titled The Causes 850 00:45:39,400 --> 00:45:42,640 Speaker 1: and Effects of corpulents naturally suggested there was only one 851 00:45:42,680 --> 00:45:46,200 Speaker 1: smart way to lose weight, move away from swamps. Yeah, 852 00:45:46,239 --> 00:45:48,640 Speaker 1: that swamps. It makes a whole lot of sense. I 853 00:45:48,640 --> 00:45:51,680 Speaker 1: think I gotta give you the title on this whe Congratulations, Mango. 854 00:45:52,120 --> 00:45:54,000 Speaker 1: I think that's it for today's show.
