Or they create, that undertone bleeds into the topic so they do mental gymnastics in order to negate or ignore or overlook what I'm actually trying to say, which it might be a very precise statement. For people with treatment resistant inflammatory bowel disease, this might make sense as a therapeutic.
And so I think it's important to acknowledge that diet touches on a lot of different things, animal welfare, climate change, and that while all these things are important, We do need to parse them in order to have precise conversations. I agree. Where we actually like evaluate the data as objectively as possible.
Well, I would say by and large, I'm diet agnostic when it comes to metabolic health. And what I mean by that is the great thing about metabolic health is the proof is in the pudding, how you feel in your biomarkers. So if an individual achieves great health, biomarkers, disease remission on a vegan diet, I will applaud them and be happy for them. Have you seen that?
i've seen people who profess to it i i mean i believe it's doable i believe it's not necessarily easy it might require supplementation i i believe it is possible i i don't have any reason to like fully doubt it and i will give that the benefit of the doubt i i don't think it's a fair assumption which is often a common assumption that eating the higher proportion plant-based you can eat the healthier you are i think that is a problematic reasoning
Again, it comes down to biomarkers. Well, not biomarkers, but like, what is the proof? How are you actually doing? And what does a particular dietary intervention actually do to you? So I'll give an example where I can actually construct a scenario where I go from a very saturated, fat-rich, animal-based, carnivoresque diet to a vegan diet and spike my LDL. and Applebee. I've done this.
I have the video breaking down how I did it. Yes, it's a party trick. Nevertheless, it's, again, legitimate and resulting in a change in a biomarker that I would say the vegan community thinks is particularly important. Probably LDL. So it's just like throwing the wrench in there of saying, look, there's so much context around this that
Do whatever you want with your diet, but don't be deluded to think that just eating more plants is gonna make you healthier.
I like it.
All right. I'm going to tease you before I talk about carnivore. Yeah. Brian Johnson. Is he healthy?
One thing you said there stood out to me, which is not for most people. And I think something we both agree on is that it doesn't really matter what works for most people if it works for you at the end of the day. With that, it's probably a good transition to talk about benefits of carnivore.
We've gotten most of our protein sources from animal-based foods, I think. for most of our evolutionary history.
But one would also argue that like when we were evolving, there wasn't a selection pressure for like longevity that our priorities as individuals and organisms have shifted. So how far can the evolution perspective really take us in assessing what's best for our health?
mentioned earlier in the pod that i had a very negative view of keto before i started it but over time i've developed an interest in probing areas of taboo carnivore is definitely one of them when it came up on my radar my first response was like this is absurd i can only meet diet this can't be healthy for you despite how i'd changed my mind on things before but i like playing devil's advocate so it started i started to dig into it a little bit more and what i found
was that there was actually a lot of basic physiology and biological plausibility
to align with some of the things that people report clinically on a carnivore diet like remission of inflammatory bowel disease which is obviously of interest to me so since that point in time i've been delving into it as a topic a little bit with respect to you know writing case series we had one on a carnivore diet for anorexia because that's obviously very controversial one for a carnivore diet for inflammatory bowel disease where we're like you know we did full medical histories we had lab reports colonoscopy reports
And we interviewed, I interviewed like 10 patients and to hear their stories, people saying like, you know, that they had had Crohn's or colitis for a couple of decades, been through a litany of immunosuppressants, been through surgeries. And this was the first thing that really like brought them back to life and gave them a new life. Like you can't ignore that. No.
especially when it's dozens of people. 10 were reported, but there are many more. And then you square that up with physiology that actually makes a lot of sense, like carnivore is usually keto, ketones in the gut reduce inflammation, higher ketone levels in the gut associated with lower IBD activity,
There's even literature showing how fiber elimination can have a therapeutic effect via changing called mucosporilium, I think, a pathobiont on the gut that can put pediatric Crohn's disease into remission. I didn't know before studying it, but actually fiber-free liquid diets are quite commonly prescribed for refractory pediatric.
And it's like 60 to 85% of cases respond. They don't teach you that in medical school because it's like, you know, I guess heresy against the beneficial effects of fiber. But say for that particular use case, I was seeing so many stories. And when I say stories, I do mean like with medical histories, lab reports, colonoscopy reports that are just overwhelming along with interesting physiology.
And it comes back to this question of, or the topic of absence of evidence isn't evidence of absence. Like nobody's done, the $3 to $5 million randomized control trial of a strict carnivore diet versus a vegan diet for IBD. I have my hypotheses about how it might turn out. I'd like to see it done.
