Why “The Game Changers” is persuasive—and why that’s a problem
- JRJoe Rogan
Ladies and gentlemen, Chris Kresser.
- CKChris Kresser
Joe, good to be back.
- JRJoe Rogan
How are you, buddy? Good to see you.
- CKChris Kresser
Great. Yeah.
- JRJoe Rogan
Uh, we are here because of the film The Game Changers. Um, I watched it. I watched it today. Uh, I watched the whole thing from start to finish. Um, and I have to say before we even start, I like the guy who's in it very much. James Wilks, very nice guy.
- CKChris Kresser
Yeah.
- JRJoe Rogan
He's, uh, an excellent fighter. He won The Ultimate Fighter. Um, and, uh, I don't think he's a bad person.
- CKChris Kresser
I, I, I've only had a little bit of interacts with him just over the past couple of days via email. He seems like a, a really great guy.
- JRJoe Rogan
Yeah, very good guy.
- CKChris Kresser
Genuine.
- JRJoe Rogan
I, I would... Well, we're gonna talk. We're just gonna get into it. So, let's-
- CKChris Kresser
Let's do it.
- JRJoe Rogan
... what, what did, what was your thoughts on the film, and, uh, what did, what stood out immediately?
- CKChris Kresser
Okay. So, little bit of context, um, you know, I think this film was the best of all the vegan documentaries that have been made. I'll just say that upfront. I think it's pretty well done as a film.
- JRJoe Rogan
Yes.
- CKChris Kresser
You, you know, it's got a big budget, pretty good storyline.
- JRJoe Rogan
James Cameron, Jackie Chan-
- CKChris Kresser
Lots of celebrities.
- JRJoe Rogan
... Arnold Schwarzenegger.
- CKChris Kresser
Arnold, um, you know, it's good graphics. Like, it's just-
- JRJoe Rogan
Mm-hmm.
- CKChris Kresser
... a well-made film.
- JRJoe Rogan
Yeah.
- CKChris Kresser
And I think it's, especially for someone who doesn't have the background to, you know, or, uh, science awareness to critique some of the claims, it's gonna be really persuasive and compelling. And I've definitely... You know, whenever a film like this comes out, my email inbox just blows up. Like, "Have you seen this film?"
- JRJoe Rogan
Right.
- CKChris Kresser
"What? Oh my God." You know, like-
- JRJoe Rogan
Right.
- CKChris Kresser
... "I'm eating meat. I'm gonna kill myself." (laughs) And-
- JRJoe Rogan
Right.
- CKChris Kresser
... it's just like, uh, and-
- 3:20 – 5:53
Gladiators as “plant-based” athletes: the prison-food framing
- JRJoe Rogan
The beginning of it I thought was so strange, when James talked about being injured and doing all the research that he did, which, uh, seems like an extraordinary amount of r- what did he say, like 1,000 hours of research? And that the thing that stood out was that the Roman gladiators, at least in this one particular location, um, according to the analysis of their bones, uh, it appears that they had a vegetarian diet.
- CKChris Kresser
Yeah. So-
- JRJoe Rogan
That they ate a lot of grain.
- CKChris Kresser
That was strange too. I mean, first of all, gladiators were basically prisoners of war or criminals, so the diet they're being fed is not-
- JRJoe Rogan
Prison food. Yeah.
- CKChris Kresser
Yeah. It's prison food.
- JRJoe Rogan
They're, they're slaves that are forced to fight to the death.
- CKChris Kresser
They had a life expectancy of about two years once they became a gladiator. And, um, it, it's interesting. They featured Fabian Konz, who is a scientist, you remember-
- JRJoe Rogan
Mm-hmm.
- CKChris Kresser
... who they talked to and definitely seemed to kind of buy into the plant-based diet idea, or the idea that they were, um, vegetarian, you know, by design or, or by choice. Uh, they didn't talk to his collaborator, Carl, Carl Grossschmidt, who's been quoted in the media saying... Here's a quote. Uh, and by the way, all of the references, full bibliography, show notes, everything are at kresser.co/gamechangers 'cause I want this to be totally evidence-based. People can check what I'm saying right there. So he said, "The vegetarian diet had nothing to do with poverty or animal rights. Gladiators, it seems, were fat. Consuming a lot of simple carbohydrates such as barley and legumes like beans was designed for survival in the arena. Packing in the carbs also packed on the pounds. Gladiators needed subcutaneous fat. A fat cushion protects you from cut wounds and shields nerves and blood vessels in a fight." So they were basically fattening them up so they could survive longer in, in the arena. It's not an ideal diet for, you know, fighting and muscle protein synthesis and nutrition. It was basically to fatten them up so they could survive longer.
- JRJoe Rogan
Yeah, this seems so obvious that I couldn't believe it was actually in the film. And it seemed, it just seemed blatantly deceptive because-
- CKChris Kresser
Yeah.
- JRJoe Rogan
... everyone knows what their life was. It's not like these were these elite athletes that were competing in the Olympic Games. These were people that they were sending out to die for other people's enjoyment.
- CKChris Kresser
Right. And the name, uh, um, my Latin's terrible. I bet... I think it was hortiari or something-
- JRJoe Rogan
Mm-hmm.
- CKChris Kresser
It means, like, barley eater.
- JRJoe Rogan
Yes.
- CKChris Kresser
It was an epithet. It was an insult. It wasn't, you know-
- JRJoe Rogan
Yes.
- CKChris Kresser
... a compliment.
- JRJoe Rogan
Right.
- CKChris Kresser
It was like, "Ha ha, you can, you only can, can afford to eat barley." (laughs) Um.
- JRJoe Rogan
Right.
- 5:53 – 9:38
From “possible” to “optimal”: claims about performance and the “vegan honeymoon”
- CKChris Kresser
So yeah, it was a bizarre way to start the film, I thought. There could, could've been better ways to do it. And let me also just say, like-If this film... If the purpose of this film was to say, "It's possible to thrive on a plant-based diet. And look, here are some athletes that have done that," I wouldn't have had any qualms with it. Clearly, there are examples of people who thrive on a plant-based diet.
- JRJoe Rogan
Yes. If you-
- CKChris Kresser
You know.
- JRJoe Rogan
... follow the diet correctly, it can be done.
- CKChris Kresser
Rich Roll, we talked about last time.
- JRJoe Rogan
Mm-hmm. Sure.
- CKChris Kresser
Scott Jurek, who's one of the athletes in the film, seemed to do well. Dottie Bausch, who's one of the athletes in the film. If you really plan it well, and you understand what you're doing, and you're on it, it's totally possible. I... No dispute with that. But where I take issue with it is it went a step further and said, "This is the optimal diet for athletes and everybody else." Which, you know, even though it was a film ostensibly about athletes, it, it definitely crossed the line into, "This is the approach that everybody should do."
- JRJoe Rogan
Yeah, I mean, they made these claims like all of a sudden people got stronger and faster and more endurance.
- CKChris Kresser
Right.
- JRJoe Rogan
Like, there's no evidence to support that.
- CKChris Kresser
Yeah.
- JRJoe Rogan
There's no evidence other than their anecdotal statements of what they did. There's... No one has ever put anyone on a vegan diet and then run them through extreme endurance tests and found a significant increase in VO2 max or-
- CKChris Kresser
Yeah.
- JRJoe Rogan
... muscle strength or any of those things.
- CKChris Kresser
Yeah.
- JRJoe Rogan
None of this has ever been done. So if it's, if it's true anecdotally for these people, it would have been really interesting if there was some actual data to go with that where they showed studies.
- CKChris Kresser
Right.
- JRJoe Rogan
I mean, we have James talking about his ability to do the battle ropes, that all of a sudden he could do an hour, and before, he could only do 10 minutes. Well, I find that really hard to believe, that you gained 50 minutes of your battle rope time just from ropes? And if that was the only thing in the film that I found hard to believe, I... you know, I'd have to let it go. I mean, the guy's an athlete. He's an amazing athlete.
- CKChris Kresser
Yeah.
- JRJoe Rogan
He was a great fighter.
- CKChris Kresser
True.
- JRJoe Rogan
He's got fantastic endurance. He has excellent martial arts technique. I would just buy it at, at face level, or at, uh, face value. But there's a lot of those.
- CKChris Kresser
There's a lot, and the th- ... I mean, we can go through it and talk about ... I mean, there's that problem, which is there's no peer-reviewed evidence to back that up. But even the anecdotal evidence is a little shaky is, is when we start to talk about some of the athletes in the film, and then also examples of athletes outside of the film who, you know, switched to a vegan diet, and we look and see what happened to them after they did that. The problem here is something that I call the vegan honeymoon, which is, you know, you take someone who's been on a standard American diet, they're eating KFC and McDonald's, et cetera, and they switch from that to a plant-based diet. Well, of course they're gonna feel better. (laughs) They've gone from eating absolute crap to real foods.
- JRJoe Rogan
Yes.
- CKChris Kresser
And so for a period of time, they're going to feel better, for sure. But then what happens over a longer period of time? You know, uh, some... Not getting enough protein, just in terms of quantity, and not getting the right quality of protein, that starts to have an impact. Micronutrient deficiencies, you know, vitamin A, zinc, calcium, iron, things like that take a while to develop. So you're not gonna see that decline in performance happen right away. It might take three months, it might take six months, it might take nine months. It depends on all kinds of factors: genetics, health status going into it, the type of exercise and activity that they're doing, the way they're implementing the diet, et cetera. So you have to not just look at what happens a month after someone goes vegan. You have to look at what happens six months, a year after, or two years after. And we can look at specific examples of that.
- JRJoe Rogan
So i- in the absence of the correct amount of amino acids, the correct amount of, uh, specific nutrients, you start to see a slow decline?
- CKChris Kresser
Right.
- JRJoe Rogan
So... And this is something that they're not taking into account?
- CKChris Kresser
Yeah.
- 9:38 – 10:36
Protein comparison controversy: peanut butter sandwich vs steak, calories, and absorption
- JRJoe Rogan
Uh, one of the things they talked about was protein content. And I immediately knew that this was not correct, or that they were being deceptive. They were talking about three ounces of steak versus, uh, what did they compare? A peanut butter sandwich-
- CKChris Kresser
(laughs)
- JRJoe Rogan
... and maybe some lentils? Is that what it was?
- CKChris Kresser
Oh, boy. Yeah. (laughs)
- JRJoe Rogan
Well, the problem is, the amino acid profile of that steak is far superior.
- CKChris Kresser
Yeah.
- JRJoe Rogan
The amount of protein that your body absorbs is far superior. It's-
- CKChris Kresser
Yeah.
- JRJoe Rogan
It's, uh, the... You're talking about a completely different thing. This is known science.
- CKChris Kresser
But-
- JRJoe Rogan
That you can get as many amino acids from plant-based proteins, but you e- need to eat a higher quantity.
- CKChris Kresser
Yeah.
- JRJoe Rogan
Right? And that's the... That's what's important. It's not the overall grams of protein. It's the quality of the protein. What's the amino acid of the b- profile of the protein, and how does your body absorb it? Again, this does not mean... Like, I'm a giant fan of hemp protein.
- CKChris Kresser
Yeah.
- JRJoe Rogan
I eat that stuff all the time.
- CKChris Kresser
Yeah.
- JRJoe Rogan
It's great. Y- y- y- It's just you can't say that protein grams are equal to protein grams, 'cause they're n- they're not.
- 10:36 – 17:25
How protein quality is actually measured: DIAAS and limiting amino acids
- CKChris Kresser
No, but it's even worse than that. J- Jamie, pull up slide four if you can. There's... I made some graphics here, 'cause, um, it's sometimes easier to understand when you're looking at a picture. So for the pro- the peanut butter sandwich thing, it was like, there's a... There's the same amount of protein in a peanut butter sandwich as there is in three ounces of beef. So I, I looked up the data, of course. (laughs) So three ounces of 90% lean ground beef has 24 grams of protein. You get two slices of wheat bread, we'll give them the benefit of the doubt that it's whole wheat and not white bread. (laughs)
- JRJoe Rogan
Okay.
- CKChris Kresser
That's five grams. One tablespoon of peanut butter is four grams. So you'd have to have five tablespoons of peanut butter in that sandwich to equal three ounces of beef. That's a third of a cup of peanut butter.
- JRJoe Rogan
That's a lot of fucking peanut butter.
- CKChris Kresser
You ever made a peanut butter sandwich with a third cup of peanut butter? (laughs)
- JRJoe Rogan
I probably have, but I'm a glutton.
- CKChris Kresser
(laughs)
- JRJoe Rogan
I'm a legit glutton.
- CKChris Kresser
(laughs)
- JRJoe Rogan
I've probably done that many times. (laughs)
- CKChris Kresser
So... And that's 600 calories-
- JRJoe Rogan
Yes.
- CKChris Kresser
... versus 200 calories from the ground beef.
- JRJoe Rogan
For the... Just for the same amount of protein-
- CKChris Kresser
Same amount. Just quantity.
- JRJoe Rogan
Quantity. Yes.
- CKChris Kresser
And we're not even getting into quality yet.
- JRJoe Rogan
Yes.
- CKChris Kresser
I'm gonna get into that in a second.
- JRJoe Rogan
Okay.
- CKChris Kresser
But we're just talking about quantity of protein.
- JRJoe Rogan
But I think they were saying peanut butter sandwich and a cup of lentils, right? Wasn't it the combined...
- CKChris Kresser
No, I think they said a th- three... Or-
- JRJoe Rogan
Or a-
- CKChris Kresser
Or a cup of lentils.
- JRJoe Rogan
Or, oh, was it or?
- CKChris Kresser
Yeah.
- JRJoe Rogan
Okay.
- CKChris Kresser
So, um...But then as you pointed out-
- JRJoe Rogan
The reality is, it'll probably be wood plus a couple wa- of lentils.
- 17:25 – 23:44
Ethics and environment: animal deaths in industrial crop farming and the scaling question
- CKChris Kresser
Um, yeah, so where to start with that? Um, so first of all, you know, the, the idea that plant-based agriculture doesn't kill animals is just false. I mean, there have been studies that show that particularly mono cropping type of plant agriculture kills far more animals than are killed in, you know, from eating cows, for example. The insects, rodents, you know, mice, birds, fish, all, uh, you know, killed in the process of industrial agriculture, and so that presents an-... an ethical dilemma, really. If you are saying I'm a vegan because I don't want my food choices to involve killing animals, is killing, you know, a whole bunch of small non-mammal animals better than killing mammals? Or what about killing more small animals than one cow?
- JRJoe Rogan
Right.
- CKChris Kresser
You know? Is, is that-
- JRJoe Rogan
Size. The size matter.
- CKChris Kresser
... ethically ... Does size matter? Does it ... You know, where do you draw the line between an animal that is, like, sentient enough or cute enough maybe to not be killed versus-
- JRJoe Rogan
Let me clarify what you're saying too. You're saying more animals per meal. So you, like, if you wanna have a meal out of wheat, you're pro- most likely, more animals are going to die than if you want... It's like if you have 100 meat wheels, uh, me- uh, wheat meals rather, 100 meals with wheat in them, you're probably killing more animals than if you have 100 meals with cows in em, because that's like a cow.
- CKChris Kresser
Yeah, I don't know the answer to that question. I just, I'm comparing kind of the whole process, you know, like eating animals versus eating plants.
- JRJoe Rogan
Mm-hmm.
- CKChris Kresser
And, uh, and, and I don't know if that per meal comparison has ever been done, but I'm just saying that that's an interesting ethical question. You know, if-
- JRJoe Rogan
Well, let me give you their argument for that. The, they say that most of these mono crops are to feed animals.
- CKChris Kresser
Uh, yeah, that is a problem. I mean, I, I fully ... Where I agree with this film is that conventional, uh, livestock practices are harmful to the planet.
- JRJoe Rogan
Right. But what they're saying is that you're saying that eating a vegan diet and all these mono crops, that these mono crops are killing all these small animals. They're saying, no, these mono crops, most of them actually exist to feed livestock.
- CKChris Kresser
That's, that's not true. I mean, if, if you follow this through, I mean, especially when you start talking about, like, fake meat and some ... You know?
- JRJoe Rogan
Yes.
- CKChris Kresser
They're, they're all ... What are, what are those based on?
- JRJoe Rogan
Soils.
- CKChris Kresser
Soil.
- JRJoe Rogan
Yeah.
- CKChris Kresser
Yeah. They're industrial crops. They're not, you know, grown on the family farm.
- JRJoe Rogan
Right.
- CKChris Kresser
These are industrial GMO mono crops.
- JRJoe Rogan
Massive, massive fields.
- CKChris Kresser
On a massive scale. Um, there was a great study published in the journal PNAS in 2017, and th- it was specifically addressing this claim of would removing animal products from our diet have, you know, saved the world basically? Would it reduce greenhouse gases? Would it improve our nutrition? Um, basically, they found that it would only reduce greenhouse gas emissions by 2.6%, but our intake of carbohydrates, total calories, um, would go way up, and the incidents of nutrient deficiencies would go way up. And they did the math and found that without animal products, domestic supplies of calcium, EPA, and DHA, which are the long chain omega-3 fats, retinol and B12 were, quote, "insufficient to meet the requirements of the US population." So translation, everybody would have to be supplementing with those nutrients if everyone went on a vegan diet. And they went on to say that, um, basically, the, there's already a surplus of calories in the diet of 145%. If everyone went ... if we removed animal products entirely, that would go up to 230%. So the, because the volume of calories in food that would be required to meet basic nutrient and protein needs would be that much higher. So, you know, there's a lot of downstream consequences that I don't think have been fully thought through. Even if a plant-based diet might work for one person, does it, will it scale? You know, if you, if you take that to the full level of, like, everyone eating a plant-based diet, which is the argument that is being made, does it really work from a nutritional perspective, from an, from an environmental perspective, and even from an ethical perspective?
- JRJoe Rogan
The environ- the environmental perspective is legitimate. They both cause environmental damage, both animal agricultural and plant agriculture. There's just no way around it.
- CKChris Kresser
Industrial ag-
- JRJoe Rogan
Yes.
- CKChris Kresser
Industrial practices cause environmental damage, yeah.
- JRJoe Rogan
And if you wanna feed 320 million people, you're not gonna do it through organic farms. You're gonna, you're gonna have to ... I mean, you can grow food in your neighborhood. I mean, if you live in a small town, you guys can have a co-op. You can have food in your backyard that you can grow. But if you're living in a city like Los Angeles, it's highly likely your food is not coming from that city itself. So that, that means it has to be grown.
- CKChris Kresser
Yeah. Yeah.
- JRJoe Rogan
And if you're gonna grow food for 20 million people, you need a giant chunk of land. If you need that giant chunk of land, even if everybody's eating vegan, that means wildlife is gonna be deplased- displaced. The, the area where you're growing crops, it's going to be a mono crop culture. You're not gonna have all these plants living together like they do in the wild. That's n- just not how you grow food for 20 million people in a very specific area.
- 23:44 – 31:32
Greenhouse gases: life-cycle accounting tricks and regenerative livestock as a carbon sink
- JRJoe Rogan
Th- there's a thing that they keep saying that you brought up slight- you l- you touched on it a little bit earlier. The, the thing is that greenhouse gases.
- CKChris Kresser
Mm-hmm.
- JRJoe Rogan
And they were talking about the greenhouse gases from meat, and it's just a fake number.I mean, it's over the top-
- CKChris Kresser
It is.
- JRJoe Rogan
... it's over the top not true.
- CKChris Kresser
Yeah.
- JRJoe Rogan
The specific number's 9% for all agriculture. All agriculture, including growing crops. The vast majority of all of our greenhouse gas issues are coming from transportation and from industry. This is, this is undisputable.
- CKChris Kresser
So this, this is where I wonder too about-
- JRJoe Rogan
So for them to s-
- CKChris Kresser
... like whether it's, is this disingen- like is this... Are they not aware of the, what's happening here or is it disingenuous? Because... So, so here's the thing, here's what they did, Joe. So the, the number in the... The specific number in the film, they say, uh, greenhouse gas emissions from cattle are 15%. And that... And they compared that to 14% for all of transportation. But the problem with that is that they're using the full life cycle analysis for cal- for livestock. So that means, um, you know, the carbon needed for feed, for transport, for processing all the cattle, not just emissions, not just methane burps-
- JRJoe Rogan
Right. Yes.
- CKChris Kresser
... from the cattle. Whereas for transportation, they're only looking at what are, what are called direct and tailpipe emissions, just the emissions that come out of the tailpipe. They're not looking at the carbon needed to manufacture the vehicle, the cars, the buses, the air- (laughs) airplanes, the inputs for making the fuel, the fuel production and distribution, the final, uh, use of the fuel. That life cycle analysis for transportation hasn't been done just because it's enormously complex and it would be a phenomenally big number. Um, the EPA has estimated that something around 80% of the greenhouse gas emissions comes from industry.
- JRJoe Rogan
Yes.
- CKChris Kresser
Basically fossil fuel. So there... It's not an apples to apples comparison. They're-
- JRJoe Rogan
Right.
- CKChris Kresser
... they're doing the full life cycle for livestock versus just the direct emissions for transportation. Well, if we look at just the direct for both, it's 5% for livestock globally and 14% for transportation. But in the US, it's only 3.9% for livestock 'cause we have more efficient practices here versus 14% for transportation. So not even in the same ballpark and it's, it just, it's... Yeah. I mean, they can just say that in a film. Most people will hear that and nod their head because they've heard those numbers before, but the devil is always in the details.
- JRJoe Rogan
Well, what's going on is what, what you see in a lot of these videos where only one person gets to talk.
- CKChris Kresser
Yeah.
- JRJoe Rogan
Right? One person who has a specific agenda, gets to cherry-pick the data and distort it, and then put it on the film. I mean, and you can accuse us of doing that right now 'cause both of us are clearly on the same page.
- CKChris Kresser
Yeah.
- JRJoe Rogan
And, uh, I would be happy to have James come in with you afterwards.
- CKChris Kresser
Yeah.
- JRJoe Rogan
We're, uh... Just... But we decided-
- CKChris Kresser
We did it with Joel.
- JRJoe Rogan
Yes. And we did... Well, James is way more reasonable than Joel.
- CKChris Kresser
Yeah.
- JRJoe Rogan
And, and not slimy. So I'd be happy to do that. And I think that when, when it's all said and done, I, I would just like people to be informed. And, uh, you're, you're... Everyone is going to have their own ideological bias. Everyone's gonna have their own preference. Everyone... But to make poorly informed decisions or... That's being kind. To be more blunt, deceptive information, forming your decisions and, and, uh, and having health consequences because of that, to me, pisses me off and freaks me out.
- CKChris Kresser
Yeah.
- JRJoe Rogan
'Cause it's, it's not... The, the, the health aspects are not being represented accurately.
- CKChris Kresser
Yeah. It particularly bothers me when kids are involved. Um-
- 31:32 – 37:43
Can regenerative agriculture feed everyone? Land constraints, soil loss, and system change
- JRJoe Rogan
Okay. Um, so this animal produ- like the, the, the, the regenerative livestock production, the- doing it in this method, is that sufficient to feed everyone? The production? I mean, how much land do you need to do something like this?
- CKChris Kresser
So I, I knew you were gonna ask that question.
- JRJoe Rogan
Okay.
- CKChris Kresser
And I talked to, um, Savory Institute about this and a few other people, and, um, basically, one response is it's the only way we're gonna feed everybody because, as I mentioned, there are only 60 harvests left because of soil degradation. So continually, you know, trying to scale up industrial plant agriculture with soy and corn and, and all of these kinds of crops is gonna further degrade the soil. And at some point, we're not gonna have any (laughs) soil left to grow stuff with.
- JRJoe Rogan
That's an important factor, right? And we, we should talk about this, that you need compost and you need fertilizer, and you need something that replenishes the soil. And doing these large-scale monoculture crops, when you have these enormous areas, they're just depleting, right? They're just pulling-
- CKChris Kresser
Yeah.
- JRJoe Rogan
... and then they have to add.
- CKChris Kresser
You can't make something from nothing.
- JRJoe Rogan
They have to add bags of minerals, right?
- CKChris Kresser
That's the thing. We're not just, we're not choosing between like, you know, two, one really good alternative and one terrible alternative. That's not a choice, (laughs) like you were saying-
- JRJoe Rogan
Right, right.
- CKChris Kresser
... before the show. Like, eh, that's not even a choice. You just do, you just obviously do the right thing. We're choosing, it's like on the one hand, if we try to scale up plant agriculture in an environment where, according to the F- FAO, our soils are in only, quote, "Fair, poor, or very poor condition," and we only have 60 harvests less, left due to rapidly deteriorating soil due to erosion and nutrient depletion, then we desperately need new methods of restoring healthy soil. And if we can do that with regenerative, holistically managed livestock, which has been shown, you know, in the scientific literature to be possible, then that may be the only way we can feed everybody.
- JRJoe Rogan
So we would need to almost have a reversal, if that was the case, and have more animal agriculture than plant agriculture.
- CKChris Kresser
But not the way it's being done now-
- JRJoe Rogan
Right, it would have to be-
- CKChris Kresser
... in the feedlot.
- JRJoe Rogan
So they would have to be l- like Joel Salatin set up-
- CKChris Kresser
Yeah, so there, there-
- JRJoe Rogan
... where he's got Polyface Farms.
- CKChris Kresser
... we would need i- three things to happen. One would be we'd need to return all the crop lands that are being used to feed livestock in feedlots right now to grassland. And number two, we'd need to put all unused land, like the rocky, hilly soil that, or, or land that can't be used for plant agriculture into production f- with animals. And number three, farmer, farmers and ranchers would need to adopt regenerative practices, you know. So I'm not saying... This is an enormous undertaking.
- JRJoe Rogan
Yes.
- CKChris Kresser
We're not, we're talking... But so is feeding the world with plant-based agriculture.
- JRJoe Rogan
Right.
- CKChris Kresser
Like, whichever direction we go, we're talking about-
- JRJoe Rogan
I understand what you're saying.
- CKChris Kresser
... you know, really, uh, systemic change that needs to happen in a big way.
- JRJoe Rogan
What percent... and then this would have, uh, you'd have to have all of the meat be grass-fed meat, 'cause they'd be e- eating what they naturally eat. Now, what is the percentage of grass-fed meat in this country currently?
- CKChris Kresser
Uh, I don't know for sure. I think the number I read was something like 2 or 3%, so very low.
- JRJoe Rogan
Very small.
- CKChris Kresser
Yeah.

Conflicts of interest and institutional influence: CEUs, Adventists, and lifestyle medicine
- CKChris Kresser
The thing is, like, we can go down that road of we can say, okay, so this film was made by James, you know, James Cameron was one of the filmmakers. He also is the owner of Verdient Foods, which is a pea protein company. And he said that he has the goal of it becoming the biggest organic pea protein company in the, in the world. He's invested $140 million into it. His wife, Susie Cameron, is founding a chain of vegan schools. And so, you know, from one perspective, that's conflict of interest. You know, this, it, this is an agenda-driven film. It's not a dispassionate, objective look, you know, scientific look at the, at the vegan diet. But, you know, (laughs) I mean, you can make that argument about just about anyone at this point. Like is it that surprising that a vegan film has a bunch of vegan medical experts in it? Is it surprising that those experts invest in what they believe in and that they write books about it? I don't think so, you know. But, but it's important to know (laughs) that and to not confuse a film like that with a scientific work.
- JRJoe Rogan
Yes.
- CKChris Kresser
And that's my problem with this is oc- the, um, what is it? The American College of Lifestyle Medicine. I have to look this up. One of these organizations is offering CEUs to doctors who watch this film and complete a quiz. That's absolutely ridiculous. (laughs) This fi- this has not been peer- this is not peer-reviewed science. This is not something that doctors should be getting CEUs for.
- JRJoe Rogan
What is a CEU?
- CKChris Kresser
Continuing education units.
- JRJoe Rogan
Mm. Oh, boy.
- CKChris Kresser
So like basically doctors have to do, any medical professional has to do a certain amount of continuing education. You know, y- generally you go to like an accredited (laughs) , um, seminar or class or, or whatever, and l- and that's how you do it. But they're actually offering those for people who, doctors who watch this film and complete a short quiz. And-
- JRJoe Rogan
Wow.
- CKChris Kresser
Yeah. That's freaky. So I don't know if we talked about this on the con show or at one of the previous one. Yeah, it was American College of Lifestyle Medicine. Well, they were founded by Seventh-day Adventists at Loma Linda University. The Seventh-day Adventist Church, do you know about this?
- JRJoe Rogan
They're vegetarians.
- CKChris Kresser
Yeah. So-
- JRJoe Rogan
Yeah.
- CKChris Kresser
... it was, uh, one of the founders was Ellen White and she taught that meat was a toxic substance and that flesh should be avoided because it increases our carnal urges.
- JRJoe Rogan
Holla.
- CKChris Kresser
(laughs) So-
- JRJoe Rogan
Yeah.
- CKChris Kresser
... it was, (laughs) it was a moral religious thing at first.
- JRJoe Rogan
Mm-hmm.
- CKChris Kresser
And then, uh, one of the other, um, an early Adventist Church member, uh, Lena Cooper, she co-founded the American Dietetic Association, which is still to this day one of our major dietetics, uh, organizations. And she wrote textbooks that were used in dietetic and nursing programs all around the y- the world for, for 30 years. So we have this weird meshing-
- JRJoe Rogan
Mm.
- CKChris Kresser
... that goes back to like the early 20th century between religion and science.
- JRJoe Rogan
Do the Seventh-day Adventists have better health overall in general? Do-
- CKChris Kresser
They do.
- JRJoe Rogan
... they like one of those Blue Zone people?
- CKChris Kresser
But, but the argument is often made that that's related to diet. Well, it could be that it's, it's related to, you know, th- part of their creed is to eat healthy whole foods, but they're also, don't smoke, they don't drink. They're a- they're advised to exercise. So it's kind of like the Dean Ornish studies where-
- JRJoe Rogan
Mm-hmm.
- CKChris Kresser
... you know, you put together all these interventions that one of which is low fat diet, and then you say that the benefit was because of the low fat diet.
- JRJoe Rogan
What you're, what you're referring to is the study that showed that... And this is what vegans like to say, that vegan diet is the... And Joel u- loves to use this one. A vegan diet is the only diet that's ever been shown in a study to reverse heart disease.
- CKChris Kresser
To clinically reverse heart disease, yeah.
- JRJoe Rogan
But what this study actually shows is these people had terrible diets. They smoked and they drank. And then they put them on a vegan diet, no smoking, no drinking, and exercise. And what do you know? Their health improved.
- 50:43 – 1:24:52
Athletes, supplements, and selective storytelling: from strongmen to MMA and “vegan after” declines
- CKChris Kresser
Yeah. He, he's mostly keto. So yeah, I mean, anyways, my point was just like I'm try, I try... I'm not super dogmatic. I'm just like I, I'm interested in what works for the most people, essentially.
- JRJoe Rogan
Right.
- CKChris Kresser
And, you know, uh, sc- you mentioned Scott Jurek, a Belgian dentist shattered his record by five days a couple years ago, and that guys was eating like Snickers and-
- JRJoe Rogan
Really?
- CKChris Kresser
... tons of crap. So I'm, I'm not saying that, that, that's-
- JRJoe Rogan
He shattered his record by five days?
- CKChris Kresser
Yeah. (laughs)
- JRJoe Rogan
Oh, Jesus.
- CKChris Kresser
I'm not saying that that's what you should-
- JRJoe Rogan
Why wasn't that in the movie?
- CKChris Kresser
(laughs) I'm not saying that's what you should do, but I'm saying there's more to athletic performance than food.
- JRJoe Rogan
I guess that's not really deceptive 'cause he did break the record. When he broke it, he did break it.
- CKChris Kresser
Yeah, he broke it.
- JRJoe Rogan
But then-
- CKChris Kresser
He's a phenomenal athlete.
- JRJoe Rogan
Yeah. But then someone else broke it again.
- CKChris Kresser
We don't... I don't wanna take that away from him, you know. And then like Michael Phelps, you know.
- JRJoe Rogan
Guy eats pizza.
- CKChris Kresser
Guy eats 12,000 calories of like sugar-
- JRJoe Rogan
(laughs)
- CKChris Kresser
... Swiss, French toast-
- JRJoe Rogan
Yeah.
- CKChris Kresser
... pizza. Um, Usain Bolt in the Beijing Olym- Olympics when he shattered those records, he fa- he ate a thousand, over a thousand chicken nuggets, I think. Somebody calculated it.
- JRJoe Rogan
(laughs) That's amazing.
- CKChris Kresser
So, you know, there's more, there's more to it than that.
- JRJoe Rogan
Well, I think when you're at that level of performance, you, you are burning off such an insane amount of calories-
- CKChris Kresser
It almost doesn't matter.
- JRJoe Rogan
... and you're working so hard, you can kind of almost eat anything.
- CKChris Kresser
When you're, when you're in that mode, for sure. Yeah.
- JRJoe Rogan
Yes. Yeah. When we d- when we... And this is obviously not comparable, but when we did Sober October last year and we had this fitness challenge, I was doing cardio, no, no joke, f- it... A minimum five hours a day, sometimes six and seven.
