So ridiculous that that was even a thing. 253 00:16:33,702 --> 00:16:36,413 But you do feel the need to cultivate this image 254 00:16:36,413 --> 00:16:40,167 of the goth, cute pastry chef with tattoos. 255 00:16:40,167 --> 00:16:43,420 There was just a massive amount of pressure on me, 256 00:16:43,420 --> 00:16:48,133 and so then I kind of just let it get out of control. 257 00:16:51,595 --> 00:16:56,433 I was really anorexic for a long time. 258 00:16:57,976 --> 00:17:02,814 But now, my eating disorder has kind of shifted to orthorexia, 259 00:17:02,814 --> 00:17:08,403 where I'm very obsessed with wellness and maximizing your nutrition. 260 00:17:09,446 --> 00:17:13,158 So this is, yeah, like, guarana, suma, reishi, lion's mane, 261 00:17:13,158 --> 00:17:16,578 Cordyceps, the spirulina, Chlorella, moringa. 262 00:17:18,330 --> 00:17:19,831 Basically, I eat a lot of vegetables 263 00:17:19,831 --> 00:17:22,501 and then supplement it with potions and powders 264 00:17:22,501 --> 00:17:25,212 and things that the Internet tells me that I probably need. 265 00:17:28,882 --> 00:17:31,259 I have taken so many things out of my diet 266 00:17:31,259 --> 00:17:34,679 and tried to reintroduce, you know, "fun foods." 267 00:17:36,264 --> 00:17:39,559 But when I eat sugar, pork, butter, things like that, 268 00:17:39,559 --> 00:17:42,437 then I feel bloated, and I feel like I have to throw up 269 00:17:42,437 --> 00:17:44,564 for three, four days afterwards. 270 00:17:46,733 --> 00:17:50,445 Which is really hard because I am trying to fix my relationship with food. 271 00:17:51,488 --> 00:17:55,117 And then when it feels like your body is betraying you, 272 00:17:56,034 --> 00:17:57,828 it's, um... 273 00:17:57,828 --> 00:18:01,206 It's hard to... to get past that. 274 00:18:06,378 --> 00:18:09,840 I think ultimately I would really love to know 275 00:18:10,423 --> 00:18:13,051 what I should be eating, or what I shouldn't be eating, 276 00:18:13,760 --> 00:18:16,930 and what healthy is for me, specifically. 277 00:18:23,353 --> 00:18:27,107 When my patients ask me, "What makes a microbiome healthy?" 278 00:18:27,107 --> 00:18:29,025 I like to compare it to a forest. 279 00:18:31,486 --> 00:18:35,532 You can't put a few healthy plants in it and expect everything to change. 280 00:18:36,616 --> 00:18:38,660 A forest needs a healthy balance 281 00:18:38,660 --> 00:18:43,999 where the plants and the life can be okay with the circumstances, 282 00:18:43,999 --> 00:18:47,043 with the light, with the water, with the nutrients from the soil 283 00:18:47,043 --> 00:18:48,962 and function together. 284 00:18:51,840 --> 00:18:55,260 Our gut bacteria, they want just a few grams of fiber 285 00:18:55,260 --> 00:18:58,138 from vegetables and fruits every day, 286 00:18:58,138 --> 00:19:02,475 and it's weird that it's so hard for us to manage this. 287 00:19:03,435 --> 00:19:06,188 Current recommendations in the United States suggest 288 00:19:06,188 --> 00:19:10,567 {\an8}that we should be eating 28 to 40 grams of dietary fiber per day. 289 00:19:10,567 --> 00:19:14,696 {\an8}And we're only eating 15 grams in the average American diet. 290 00:19:14,696 --> 00:19:17,532 {\an8}The field of microbiome science is realizing 291 00:19:17,532 --> 00:19:22,245 {\an8}that we probably should be eating in excess of 50 grams per day. 292 00:19:56,321 --> 00:19:58,949 How much fiber is in one hot dog? 293 00:20:00,742 --> 00:20:02,452 What? Zero grams! 294 00:20:05,872 --> 00:20:08,375 Whether you have meat on your plate or not... 295 00:20:08,375 --> 00:20:11,253 You can be vegan, non-vegan. Doesn't matter. 296 00:20:11,253 --> 00:20:16,007 The key is getting the diversity of plants in all their forms, 297 00:20:16,007 --> 00:20:19,678 as many as you can on your plate to feed your microbes. 298 00:20:21,471 --> 00:20:23,598 Why should I eat my veggies? You know? 299 00:20:23,598 --> 00:20:26,977 I'm a big fan of understanding this. Of course, there are many nutrients in it, 300 00:20:26,977 --> 00:20:29,771 and not so many bad things that are in processed foods. 301 00:20:32,607 --> 00:20:35,277 But also if the front part of your body was see-through, 302 00:20:35,277 --> 00:20:39,572 you could actually see digestion, and you would be able to very easily see 303 00:20:39,572 --> 00:20:42,242 the difference between processed foods and vegetables. 304 00:20:43,493 --> 00:20:45,203 With processed foods, you could see 305 00:20:45,203 --> 00:20:47,872 that within the first centimeters of the small intestine, 306 00:20:47,872 --> 00:20:50,166 it's basically all taken up in the blood. 307 00:20:51,584 --> 00:20:54,170 There's a surge of sugar in the bloodstream, 308 00:20:54,170 --> 00:20:56,423 and we have to pack it in the cells really fast. 309 00:20:56,423 --> 00:20:59,759 It's, like, almost a stressful event, actually, for the body, 310 00:20:59,759 --> 00:21:02,887 because, "Where should I put all this sugar?" You know? 311 00:21:02,887 --> 00:21:04,639 It has to really push it everywhere. 312 00:21:05,807 --> 00:21:08,226 But with the fiber that we have in vegetables, 313 00:21:08,226 --> 00:21:09,978 it's just more stable. 314 00:21:10,937 --> 00:21:14,024 It would be taken up a little bit, go further, 315 00:21:14,024 --> 00:21:15,900 be taken up a little bit, go further. 316 00:21:15,900 --> 00:21:17,819 It would even land in the colon 317 00:21:17,819 --> 00:21:21,323 and would be a good source of food for the microbes there. 318 00:21:21,323 --> 00:21:22,240 Delicious! 319 00:21:22,240 --> 00:21:24,868 So it's a completely different mode of digesting. 320 00:21:24,868 --> 00:21:27,871 You know, like a long walk instead of sprinting. 321 00:21:32,334 --> 00:21:37,005 If a gut microbiome is very diverse, has many different kinds of bacteria, 322 00:21:37,005 --> 00:21:39,382 it'll just have this bouquet of possibilities 323 00:21:39,382 --> 00:21:41,926 to react to what life throws at us. 324 00:22:00,070 --> 00:22:03,323 Kobayashi continues to just pound 'em down. 325 00:22:05,408 --> 00:22:09,454 Putting on a clinic. Look at him go. He's moving his arms and... 326 00:22:10,038 --> 00:22:14,751 So what happens if we don't eat enough fiber to feed these microbes? 327 00:22:14,751 --> 00:22:17,212 Takeru Kobayashi! 328 00:22:17,212 --> 00:22:20,340 If you're not feeding your gut microbes dietary fiber, 329 00:22:20,340 --> 00:22:22,759 your gut microbes will start eating you. 330 00:22:24,969 --> 00:22:28,264 All these microbes are great. They help your body a lot. 331 00:22:29,599 --> 00:22:31,017 But they're also microbes. 332 00:22:31,017 --> 00:22:34,938 So there has to be a friendly border of respect, and this is produced by mucus. 333 00:22:36,022 --> 00:22:39,317 Mucus is a good way of doing that because it's also a bit permeable, 334 00:22:39,317 --> 00:22:41,945 {\an8}so nutrients and everything can come through, 335 00:22:41,945 --> 00:22:45,115 {\an8}but the microbes are being held a little bit distant. 336 00:22:46,199 --> 00:22:48,993 Well, it turns out if you stop eating dietary fiber... 337 00:22:48,993 --> 00:22:49,994 No! No! No! 338 00:22:49,994 --> 00:22:52,997 ...the gut microbes still need to eat something, 339 00:22:52,997 --> 00:22:57,127 so they will start eating that mucus lining as a backup food source. 340 00:22:58,378 --> 00:23:01,589 And gradually, over time, they'll deplete that mucus lining. 341 00:23:02,424 --> 00:23:05,760 Your bacteria are going to places in the body 342 00:23:05,760 --> 00:23:07,303 where they're not supposed to go. 343 00:23:08,471 --> 00:23:11,808 And when immune cells that reside there see that, 344 00:23:11,808 --> 00:23:14,060 - they go into a defense mode. 345 00:23:15,145 --> 00:23:17,897 And this can cause a battle of inflammation, 346 00:23:17,897 --> 00:23:22,026 and it can change the microbial composition of your gut. 347 00:23:22,735 --> 00:23:26,114 And that is one of the things that can lead to many diseases 348 00:23:26,114 --> 00:23:28,074 like inflammatory bowel disease, 349 00:23:28,074 --> 00:23:30,869 or some types of irritable bowel syndrome. 350 00:23:36,082 --> 00:23:39,627 When we started to explore chronic inflammatory diseases, 351 00:23:39,627 --> 00:23:42,046 scientists had this thought of, 352 00:23:42,046 --> 00:23:45,216 can we find the microbe or the microbial community 353 00:23:45,216 --> 00:23:49,220 that makes this disease or creates that feeling that's bad? 354 00:23:49,888 --> 00:23:53,641 But now when we think about how this ecosystem interacts, 355 00:23:53,641 --> 00:23:57,479 we have this newer approach where we also ask ourselves 356 00:23:57,479 --> 00:24:01,399 if we are missing certain bacteria that are usually there to protect us. 357 00:24:14,454 --> 00:24:16,414 My name is Daniell Koepke, 358 00:24:16,414 --> 00:24:20,793 {\an8}and I am a clinical psychology doctoral student. 359 00:24:21,794 --> 00:24:25,089 It's really hard for me to remember what it was like to eat food 360 00:24:25,089 --> 00:24:31,054 before it became associated with anxiety and pain and discomfort. 361 00:24:32,180 --> 00:24:36,518 When I was in undergrad, I had a pretty bad diet. 362 00:24:37,060 --> 00:24:40,271 And that diet, the high-sugar foods 363 00:24:40,271 --> 00:24:43,733 and the absence of more fruits and vegetables, 364 00:24:43,733 --> 00:24:45,693 led to IBS-like symptoms. 365 00:24:46,277 --> 00:24:48,780 So I was experiencing indigestion, 366 00:24:48,780 --> 00:24:51,157 stabbing pains from trapped gas, 367 00:24:51,157 --> 00:24:54,285 constipation, not being able to go to the bathroom at all. 368 00:24:55,995 --> 00:25:00,667 When you have multiple gut symptoms that can't be easily put into a box, 369 00:25:00,667 --> 00:25:03,294 a lot of doctors don't know what to do. 370 00:25:04,420 --> 00:25:07,173 Antibiotics are given out like candy. 371 00:25:07,173 --> 00:25:09,509 "You don't feel good or think you might have this thing?" 372 00:25:09,509 --> 00:25:10,843 "Here. Take some antibiotics." 373 00:25:12,387 --> 00:25:17,100 In the last five years, I've been on six rounds of antibiotics in a year. 374 00:25:18,977 --> 00:25:21,980 I lost a lot of weight when I started getting sick 375 00:25:21,980 --> 00:25:24,524 and had to cut all of these things out of my diet. 376 00:25:26,317 --> 00:25:28,236 I don't know how many things I can eat now, 377 00:25:28,236 --> 00:25:32,282 but it's probably anywhere between 10 and 15. 378 00:25:33,408 --> 00:25:39,539 It feels really limiting, and I often feel really deprived. 379 00:25:41,666 --> 00:25:48,006 So I have to take these supplements to maintain my baseline functioning. 380 00:25:49,465 --> 00:25:52,010 These are even more supplements that... 381 00:25:52,010 --> 00:25:55,972 ...I've taken in the past that no longer work. Um... 382 00:25:56,514 --> 00:25:58,558 I know that pills aren't the answer, 383 00:25:58,558 --> 00:26:04,856 {\an8}but I feel stuck because I don't know how to grow these new bacteria that I need 384 00:26:04,856 --> 00:26:07,358 {\an8}when I can't eat a lot of these foods, uh, 385 00:26:07,358 --> 00:26:10,903 {\an8}that are required to, like, have a healthy gut microbiome. 386 00:26:13,281 --> 00:26:18,328 If we cut foods out of our diet, we'll change our microbes drastically, 387 00:26:19,162 --> 00:26:21,789 because who can live there if you don't feed them? 388 00:26:24,334 --> 00:26:27,045 And if we want to reintroduce fiber, 389 00:26:27,045 --> 00:26:29,130 we'll have a far more difficult time. 390 00:26:30,214 --> 00:26:34,344 So people who suddenly eat healthy again will be bloated, 391 00:26:34,344 --> 00:26:36,387 will have some stomach pain. 392 00:26:37,180 --> 00:26:40,516 So it's a process of changing their diet, but not too drastically, 393 00:26:40,516 --> 00:26:44,562 in a way that all the microbes in the gut can adjust. 394 00:26:46,773 --> 00:26:49,651 Since I've had such a restrictive diet, 395 00:26:50,610 --> 00:26:56,699 I wonder was I also starving the microbes in my body at the same time? 396 00:26:58,534 --> 00:27:01,371 And has that changed how my body can process foods, 397 00:27:01,371 --> 00:27:03,915 and does that mean, like, my future, 398 00:27:03,915 --> 00:27:06,542 I'm always going to have issues with eating something, 399 00:27:07,794 --> 00:27:10,254 or is it partially a mental block? 400 00:27:10,254 --> 00:27:13,966 I'm not really sure... ...what's going on. 401 00:27:15,385 --> 00:27:18,429 It's something that I would love to actually learn more about. 402 00:27:27,105 --> 00:27:29,107 Oh.

This is like a spoon. 413 00:28:18,030 --> 00:28:19,615 I guess you do this. 414 00:28:21,117 --> 00:28:23,035 I've always found the idea 415 00:28:23,035 --> 00:28:25,037 of gut testing really fascinating. 416 00:28:25,621 --> 00:28:28,124 It would be awesome if I could understand 417 00:28:28,124 --> 00:28:29,959 what's happening in my own body. 418 00:28:31,294 --> 00:28:34,172 I've tried so many different things to lose weight. 419 00:28:34,881 --> 00:28:37,133 Hopefully, this might be the thing for me. 420 00:28:37,800 --> 00:28:41,095 I want the test to tell me why I don't have an appetite. 421 00:28:41,095 --> 00:28:44,807 And about the relationship between my organs and eating. 422 00:28:45,600 --> 00:28:48,853 I've never had my gut microbiome tested. 423 00:28:48,853 --> 00:28:52,982 I don't think, at this point of time, it makes a lot of sense. 424 00:28:53,858 --> 00:28:55,860 All the things you can do to have a healthy gut, 425 00:28:55,860 --> 00:28:58,946 eating differently, treating your gut nicer, 426 00:28:58,946 --> 00:29:02,617 you can do them without having an analysis first. 427 00:29:04,035 --> 00:29:06,621 But if you just want to do a fun experiment, go ahead. 428 00:29:06,621 --> 00:29:09,207 And for research, it's a great tool. 429 00:29:15,755 --> 00:29:18,216 At the beginning of microbiome science, 430 00:29:18,216 --> 00:29:20,384 we were really our own guinea pigs. 431 00:29:21,302 --> 00:29:24,555 So myself and my colleagues were collecting our own poop 432 00:29:24,555 --> 00:29:26,307 and sticking it in freezers. 433 00:29:28,100 --> 00:29:31,771 {\an8}So you take a little piece of used toilet paper, you color the piece you swab 434 00:29:31,771 --> 00:29:34,023 {\an8}with a little bit of poop, make it a bit brown, 435 00:29:34,023 --> 00:29:35,775 then we extract the DNA from that. 436 00:29:35,775 --> 00:29:39,737 But now we've expanded to thousands of thousands of samples 437 00:29:39,737 --> 00:29:41,823 from thousands of people around the United States 438 00:29:41,823 --> 00:29:43,407 and, indeed, around the world now. 439 00:29:47,620 --> 00:29:50,957 If you gave me your microbiome sample, I wouldn't be able to tell you 440 00:29:50,957 --> 00:29:54,335 a hell of a lot about how sick or healthy you are. 441 00:29:55,002 --> 00:29:59,507 I can only do that by comparing you to a really large group of people 442 00:29:59,507 --> 00:30:00,800 and seeing how you fit. 443 00:30:02,385 --> 00:30:05,513 Does your microbiome look like people who have asthma? 444 00:30:05,513 --> 00:30:06,597 Do you have asthma? 445 00:30:06,597 --> 00:30:09,016 Does your microbiome look like people who are obese? 446 00:30:09,016 --> 00:30:10,518 Are you obese? 447 00:30:10,518 --> 00:30:12,728 If that's true, then I can find a signature, 448 00:30:12,728 --> 00:30:14,522 which can help me unpin that. 449 00:30:15,857 --> 00:30:20,236 Each teaspoon of stool contains terabytes and terabytes of information 450 00:30:20,236 --> 00:30:22,822 encoded in the DNA of the microbes. 451 00:30:22,822 --> 00:30:27,493 {\an8}So each dot on the screen represents all the complexity of the microbiome 452 00:30:27,493 --> 00:30:30,705 {\an8}of one person distilled just down to one point. 453 00:30:31,998 --> 00:30:34,417 So what this display shows you 454 00:30:34,417 --> 00:30:37,253 is what kinds of microbes are shared between samples. 455 00:30:37,253 --> 00:30:39,338 So two samples that are close together 456 00:30:39,338 --> 00:30:42,633 are ones that have very similar microbial communities, 457 00:30:42,633 --> 00:30:44,302 whereas samples that are far apart 458 00:30:44,302 --> 00:30:46,679 have entirely distinct communities from one another. 459 00:30:50,224 --> 00:30:52,685 When we started studying the gut microbiome, 460 00:30:52,685 --> 00:30:54,395 the field assumed 461 00:30:54,395 --> 00:30:57,899 that if we looked at the gut microbiome of healthy Americans, 462 00:30:57,899 --> 00:31:01,903 we would get a good picture of what a healthy microbiome is. 463 00:31:04,989 --> 00:31:08,200 This visualization shows the differences between microbes 464 00:31:08,200 --> 00:31:11,120 {\an8}of the industrialized world down at the bottom, 465 00:31:11,120 --> 00:31:14,707 {\an8}versus the less industrial world up on the top there. 466 00:31:15,666 --> 00:31:19,712 {\an8}What you can see so clearly is how, in the non-industrialized microbiome, 467 00:31:19,712 --> 00:31:21,464 {\an8}you have more diversity. 468 00:31:22,924 --> 00:31:26,093 So if we only focus on the Western world, 469 00:31:26,093 --> 00:31:28,179 {\an8}then we are not getting a full picture 470 00:31:28,179 --> 00:31:32,266 {\an8}of what a healthy gut microbiome composition looks like, 471 00:31:32,266 --> 00:31:33,893 {\an8}or looked like in the past. 472 00:31:46,405 --> 00:31:49,116 It's difficult to walk here. 473 00:31:52,620 --> 00:31:55,331 We're going to traditional communities 474 00:31:55,331 --> 00:31:59,251 and asking people to donate their... their... their poop. 475 00:31:59,251 --> 00:32:01,212 - Namaste. - Namaste. 476 00:32:03,798 --> 00:32:05,800 When we go to communities 477 00:32:05,800 --> 00:32:07,426 and say "Can we collect your poop?" 478 00:32:07,426 --> 00:32:11,055 Most of the time people are like, "Oh no, no, no. Poop? No. Poop, no." 479 00:32:12,098 --> 00:32:17,645 But when I explain to them what I'm doing, they're like, "Sure. Why not?" 480 00:32:23,192 --> 00:32:27,446 It turns out that the gut microbiome of rural populations 481 00:32:27,446 --> 00:32:29,323 have hundreds of more species 482 00:32:29,323 --> 00:32:32,868 that we just don't see in the industrialized gut microbiome. 483 00:32:34,954 --> 00:32:40,418 By studying populations that are still practicing traditional lives, 484 00:32:40,418 --> 00:32:42,503 we will begin to understand 485 00:32:42,503 --> 00:32:46,757 what microbes have been lost from industrial populations, 486 00:32:47,466 --> 00:32:50,177 and how this is influencing our overall health. 487 00:32:58,561 --> 00:33:00,187 {\an8}We ready? 488 00:33:00,187 --> 00:33:02,023 {\an8}Hi, Maya.

Yeah. 491 00:33:06,694 --> 00:33:10,906 {\an8}What we found in our studies is that overall, you're pretty healthy. 492 00:33:10,906 --> 00:33:12,783 It's definitely above average. 493 00:33:12,783 --> 00:33:15,703 {\an8}All those vegetables you're eating every week have not gone to waste. 494 00:33:15,703 --> 00:33:16,620 Cool. 495 00:33:16,620 --> 00:33:20,833 {\an8}You know, I've also struggled with having a disordered relationship with eating. 496 00:33:20,833 --> 00:33:23,753 I've always been very, kind of, restrictive in my diet. 497 00:33:23,753 --> 00:33:26,130 {\an8}So, Maya, yeah, many people think like you, 498 00:33:26,130 --> 00:33:30,468 {\an8}that just having a really healthy kale salad every day 499 00:33:30,468 --> 00:33:32,595 {\an8}is going to keep them healthy. 500 00:33:32,595 --> 00:33:35,222 That's not as healthy as we thought. 501 00:33:35,222 --> 00:33:40,061 The more diversity you consume, the more rich your microbiome will be, 502 00:33:40,061 --> 00:33:43,105 the more species of bacteria that will be present inside your gut. 503 00:33:43,105 --> 00:33:48,319 And that does allow you to deal with allergies and intolerances better. 504 00:33:48,319 --> 00:33:50,988 {\an8}- Yeah. - It's not about restricting things. 505 00:33:50,988 --> 00:33:56,786 {\an8}It's about enlarging your world of foods that are possible for you to eat. 506 00:33:56,786 --> 00:34:01,582 Well, I think part of the problem is that I have some kind of, like, mental blocks 507 00:34:01,582 --> 00:34:03,417 for some foods, like pork, 508 00:34:03,417 --> 00:34:07,046 and occasionally my stomach just reacts really poorly to it. 509 00:34:07,046 --> 00:34:09,173 {\an8}Is that something that I can overcome, 510 00:34:09,173 --> 00:34:12,968 {\an8}or is it just I'm never gonna eat bacon ever again in my entire life? 511 00:34:12,968 --> 00:34:14,512 {\an8}Oh! Don't say that. Sounds horrible. 512 00:34:16,305 --> 00:34:18,599 - Yeah. It's a struggle, right? - Yeah. 513 00:34:18,599 --> 00:34:21,727 We do think to alleviate it, 514 00:34:21,727 --> 00:34:24,980 introducing these things in very small doses, microdosing, 515 00:34:24,980 --> 00:34:29,193 {\an8}and then building it up over time into large doses can play a role. 516 00:34:29,193 --> 00:34:32,822 Try small amounts, you know, bring them into your diet. 517 00:34:32,822 --> 00:34:35,407 And if you do that gradually over months, 518 00:34:35,407 --> 00:34:40,746 you might start to regain the ability to eat a much wider range of foods. 519 00:34:40,746 --> 00:34:44,583 I do really love the idea of microdosing chips, though. 520 00:34:44,583 --> 00:34:46,043 {\an8}Oh man.

554 00:37:20,656 --> 00:37:25,369 As a physician, when we try to explain to our patients 555 00:37:25,369 --> 00:37:28,831 why they're having such a hard time losing weight, 556 00:37:28,831 --> 00:37:32,876 {\an8}we have a tendency of blaming the individuals, blaming the patients. 557 00:37:35,212 --> 00:37:38,716 The population has been doing what we were recommending 558 00:37:38,716 --> 00:37:40,134 for many decades, 559 00:37:40,134 --> 00:37:45,514 yet the obesity epidemic has not slowed down or reversed. 560 00:37:48,934 --> 00:37:50,894 The word "diet" is really confusing. 561 00:37:50,894 --> 00:37:52,479 Low-fat versus low-carb. 562 00:37:53,230 --> 00:37:56,734 {\an8}Most people understand it to be really a sprint that I'm gonna do 563 00:37:56,734 --> 00:37:59,361 {\an8}for some period of time to lose weight, 564 00:37:59,361 --> 00:38:02,197 and then I can go back to my previous patterns 565 00:38:02,197 --> 00:38:04,450 of eating whatever I want to eat. 566 00:38:05,534 --> 00:38:09,621 But a diet, it's really about changing your lifestyle for life. 567 00:38:12,916 --> 00:38:17,379 Another reason why diets don't work is that they really focus on the wrong thing. 568 00:38:17,379 --> 00:38:21,675 And in that sense, they actually could be misdirecting us. 569 00:38:23,886 --> 00:38:26,805 When we put these calorie labels on boxes, 570 00:38:26,805 --> 00:38:28,849 we think, "Okay, this is the amount of energy 571 00:38:28,849 --> 00:38:31,894 that we will all extract if we ate that same food." 572 00:38:31,894 --> 00:38:33,687 But of course, that is not true. 573 00:38:38,150 --> 00:38:40,736 If you would give an identical apple 574 00:38:40,736 --> 00:38:42,654 to three different people, 575 00:38:42,654 --> 00:38:47,618 each of these individuals would show a different response to the same apple. 576 00:38:52,956 --> 00:38:54,833 You know I can't eat this, right? 577 00:38:55,667 --> 00:38:58,587 They will each process it in a different way. 578 00:38:58,587 --> 00:39:02,257 They will each extract different nutrients from it. 579 00:39:04,218 --> 00:39:06,845 They will each extract different amounts of energies. 580 00:39:07,679 --> 00:39:10,682 You go your whole life thinking, "Okay, it's calories." 581 00:39:10,682 --> 00:39:12,643 "Me and you can eat the same thing, 582 00:39:12,643 --> 00:39:15,187 and we should both have the same results, ultimately," 583 00:39:15,187 --> 00:39:17,439 and that's just not what it is. 584 00:39:18,816 --> 00:39:21,652 So, rather than measuring the apple, 585 00:39:21,652 --> 00:39:24,571 one needs to start measuring the people who eat the apple. 586 00:39:25,864 --> 00:39:27,908 Now we focus on blood glucose levels 587 00:39:27,908 --> 00:39:29,910 in the two hours after you eat a meal 588 00:39:29,910 --> 00:39:33,747 because we understand that your blood sugar levels after a meal 589 00:39:33,747 --> 00:39:37,501 are directly connected to weight loss and weight gain, 590 00:39:38,335 --> 00:39:41,296 and also to the development of multiple diseases. 591 00:39:43,757 --> 00:39:44,967 Good, good, good. 592 00:39:44,967 --> 00:39:47,177 Some cream cheese. 593 00:39:49,388 --> 00:39:51,598 I ought to check my sugar levels this morning. 594 00:39:51,598 --> 00:39:53,016 Especially after that. 595 00:39:53,016 --> 00:39:54,476 Let's see if I beat you. 596 00:39:55,436 --> 00:39:57,229 Oh my God, you're going up really fast. 597 00:39:57,229 --> 00:39:59,565 {\an8}- Definitely beat you this time.
