[@Elliot_97]

9:21 That's because there hasn't been a study comparing Carnivore Diet + Fiber supplement vs Carnivore Diet and no Fiber supplement. My understanding is that fiber dampens blood sugar/insulin spikes and so in standard diets consuming carbs and sugar, fiber can offset some of that blood sugar/insulin elevation and thus provides a benefit. But if your diet has no carbs or sugar, that function of fiber is no longer relevant and thus has no positive benefit. You also don't need whatever particular bacteria that fiber feeds if you're on a carnivore diet. You can process all the food on that diet without it. Furthermore Butyrate is not some unique must have molecule - it get's converted to Ketones according to Dr Paul Mason, which we have plenty of on Carnivore. Curious to hear any counterarguments to all this. I'm not an expert but this is what I've come to understand in my research.

[@Physionic]

All good points, Elliot. You're right - there haven't been any studies making those comparisons - I'm looking forward to when there are (it'll be a few years). However, fiber's microbiome effects extend far beyond butyrate - that was just one example of many. So, taking care of the microbiome is essential, regardless of diet - especially since it has wide reaching effects, beyond blood sugar and insulin, as well.

[@Sundara229]

No counterargument to your points specifically, but to the Carnivore diet as a whole: There is still the potential issue of elevated LDL and oxidative stress (which some people claim doesn't matter, but so far I haven't seen concrete, bullet-proof evidence why it wouldn't), the carcinogenic effect of heme-iron and significantly elevated cortisol levels (due to it's role in blood sugar regulation) and TMAO's.

[@Elliot_97]

@@Sundara229 The argument for LDL is that there's actually like 4 or 5 subgroups within 'LDL', varying in size. Only the smallest ones cause problems because it makes them unrecognizable to the liver and thus the liver doesn't properly uptake that circulating LDL. But what happens in blood tests of people on the carnivore diet is their total LDL goes up yes, but its almost entirely made up of the larger forms of LDL that are still recognised by the liver, and thus cause no harm. Furthermore, its general poor metabolic health, perhaps seed oils, perhaps alcohol/tobacco, that cause the oxidative stress which transforms LDL into these smaller versions that the liver can't recognise. And those things are not caused by the carnivore diet.

[@gungadin164]

Wish I could remember the details of the research I recently came across while looking into probiotics for my post-surgical child--the gist of it was that, when one takes a course of antibiotics and disrupts one's intestinal biome, there are three conceivable ways of proceeding after treatment has ended. (1) Perform a stool substitute transplant; (2) do nothing; (3) take probiotics. The study found that, if course 1 is followed, re-population of the gut occurs within a few days; if course 2 is followed, the re-population process takes a couple of weeks; if course 3 is followed, re-population is delayed by five months or more. As I recall, the theory advanced to explain this counterintuitive result was that the microorganisms that were introduced in the probiotic package were not native species and in fact competed against the indigenous microorganisms, delaying their proliferation and enabling the rise of rogue strains that, in the ordinary course of affairs, would have been suppressed by the native flora. Lactobacillus, especially, seemed to be a major antagonist of native species and a disruptor of gut equilibrium (and, of course, it's probably the most commonly-consumed probiotic).

[@sophie4636]

It makes sense, doesn't it? A huge amount of one strain will just fill the gut with that one type, usually lactobacilius... I don't think enough is known about the gut microbiome for us to fall for the huge marketing put into making us buy these products...

[@reinerheiner1148]

I'd be highly sceptical of anything norton says that is not his main area of expertise. Once he made a video about hydrolized collagen saying it does nothing if i remember correctly. But the funny thing was that he instead said one should supplement with hydroxproline instead. Which is completely absurd. For those who don't know: hydroxyproline is part of collagen which would seem like a good choice to supplement with. But, the body cannot use hydroxyproline directly, it has to be broken up to get proline, then used to create procollagen. And only afterwards proline is hydroxylated. On the contrary, hydroxyproline increases the chance for kidney stones. And on a high protein diet, proline is not in short supply anyways( better supplement with glycine...) Long story short, he had no idea what he was talking about and from that time on I was very sceptical about what he says.... Thanks for the commentary.

[@Physionic]

Thanks for sharing, Reiner. I haven't run across that statement by him, but I could easily have missed it. Like you, I feel collagen supplementation has more in its favor than Dr. Norton seems to think, although, admittedly, the evidence is sparse.

Hi Nick. I just subscribed to your podcast a couple of weeks ago and already become attached to catch up with all of your previous videos. I am chemical Engineer and have been involved in nutrition for a long time. I am subscribed to a number of podcasts on this, including Peter Attia, Huberman, Thomas DeLauer… and one that I want you to follow: fitness revolucionario by Marcos Vazquez. I would like you to talk about “good” saturated fats. I believe that there have been satanized by mixing them in the same bowl as PROCESSED saturated fats. “Good” saturated fats: chicken skin, pork skin, lard, butter… “Bad” saturated fats: processed meats: jam, bacon, salami… We would love your breakdown on these and learn what has been published on this.

Would love to see a study done with strict carnivores divided into carnivore as usual and the other half carnivore plus prebiotic...maybe using the markers for the Horvath clock, or similar aging clock as the reference - taken before and and at end of study. Carnivore certainly cuts down on the dietary variables.

[@MarmaladeINFP]

It would be difficult, maybe impossible, to create a strict carnivore diet without prebiotics. Many substances in animal foods, such as collagen and fat, will feed gut microbes.

[@ThingsYoudontwanttohear]

Isn't healthy user bias something different than what Norton and Hubberman discussed? Healthy user bias as they described it is quite easily controlled for by matching participants with similar confounders like exercise, protein content of diet, smaking until only the fiber intake is different between matched groups. Actual healthy user bias is a selection bias that cannot be controlled for after the participants have been selected for the study. People that are actively trying to be healthier tend to be more likely to sign up for a health study so the study population ends up not being representative of the general much unhealthier population. Like all those people that signed up for that carnivore study for instance.

[@Physionic]

You could have a point there. I suppose one could interpret it either way; with both being important. The scenario you're describing definitely happens, but often researchers will screen participants pre-study to make sure they meet eligibility criteria for "unhealthy". So, for example, a study on fiber and hypertension would make sure all participants meet the requisite pathology of hypertension. If they do not, they are deemed ineligible to be part of the study. I think there are some populations that this still doesn't address (like race, ethnicity, etc.), but it would address the health aspects of people's lives.

[@ThingsYoudontwanttohear]

@@Physionic I agree that both interpretations of health user bias are important to combat and these are thankfully properly combatted in the majority of studies. Yet, my interpretation of healthy user bias is not limited to epidemiology and is combatted in the participant selection phase of the research process in contrast to the data analysis phase. Because of this the interpretation of this bias by Norton and Huberman might be better described by 'multicollinearity' as multicollinearity means several independent variables in a model are correlated like high fiber intake and exercise, processed food intake. I will admit I am nit-picking, but seeing that many people think epidemiological studies are useless no matter how well they are done (and their participants are selected with incredible care) because "healthy user bias cannot be controlled for in such studies" I hope you understand my nit-picking.

[@VegetaPrinceOfSaiyans]

There are some studies that use multiple models to produce the final measurements, and one i read recently used 4 or 5 different models and accounted for factors like you mentioned in one of them.

[@Pyjam-0702]

Context is certainly important. On a high-carbohydrate diet, fiber seems essential. On a strictly carnivorous diet, why would a diverse microbiome be necessary when the diet is not? Isn't the important thing for health the butyrate? And isn't butyrate one of the ketone bodies produced in abundance when one is on a carnivorous diet and the body is in ketosis? We know of at least one example in the carnivore community of someone who has been a carnivore for 40 years and has not seen a doctor or dentist in over 30 years. We should not make a generalization, but this diet does not seem to be fatal in the short term in any case.

[@MarmaladeINFP]

I think it was Dr. Shawn Baker and/or Dr. Paul Saladino who measured the microbiomes of patients on the carnivore diet. As I recall, their microbiomes were as large and diverse as the microbiomes of people on a so-called 'balanced' diet with plenty of fiber.

I think with the study of the microbiome still in its infancy, we should be careful not to read too much into them. For instance, is more diversity good or bad? Probably depends on what kind of diversity I'd imagine. One of the things that struck me was on bowel movement when Dr Norton was talking about fiber. I started thinking, how do we know what is even optimal? "You go more often and had bulk to stool". Is that good or bad? I think the biggest caveat is that some folks may think that optimal gut health is the end all, be all. Even if it were, we don't know exactly how to achieve it. Then there's the whole psychological aspect of nutrition. Probably the best advice at this time would be to get as far away from the Standard American diet as possible. Minimize processed foods and go for whole foods as much as possible.

yep that's what i got from the Podcast.. he is basically insinuating More diverse gut microbiome means good for you. How can he say that when this is a relatively new field in health and medicine.

[@RHIMYM]

it's been proven that a diverse microbiome tends to be more healthy than a less diverse. Now what's true is to know exaclty wht is diverse or not but the fact that diversity is important is known

[@icebox_Intruder]

The question isn't: "Is low gut diversity bad?" The question is: "Is diversity good or even necessary?" It's simply supply and demand. As you stated, if saturated fats go up (which require their own bacterial type), then fiber (and like) intake goes down. If there's no or lesser fiber or plant material, then it stands to reason the bacteria won't be there or are less likely to be there, i.e., "less diversity." If the body doesn't need it, then why would it have it?

The are also studies that point to higher cardiovascular risk (lower risk of diabetes) and more prevalence of gout (as with Taiwanese aboriginals and Maori). As for diet I understand Inuit consume mostly marine and terrestrial mammals, and sea birds and fish, but what would be relevant is the role of salt (higher levels of uric acid when in a carnivore diet) and calcium intake, lack of vitD during the darker months (which helps to absorb calcium in the bones) and the pollutants present in the meat they consume.

Getting SCFAs in the gut creates solid barrier in the large intestine. Inside your gut microbiota is a large amounts of bacteroides, which are gram-negative bacteria. On the shells of these microbes are lipopolysaccharides or LPS. These LPS molecules are harmless if they stay inside your intestine, but if they leak out into your bloodstream, they hook up with LDL cholesterol start a chain reaction of a lot of bad stuff that's going to hit you down the road. The butyrate prevents this.

Thank you for this thoughtful analysis. Assume for a minute that humans evolved primarily from eating meat often with little or no plant material except in extreme survival situations. Why would we give any credence to studies where the pool of subjects are plant stuffed? Of course they will have a more diverse microbiome, they are trying to digest non-optimal material. Of course they will benefit from fiber, they have a challenging and unnatural digestive task.

Fiber rich food are not processed foods, so that's a big confounder. But before getting into details I always first like to look at some high level properties. Here are some high level properties of vegan vs carnivore diet which means high fiber vs low (zero) fiber: Vegans get sick more often than average. Carnivores get sick less often than average. This always needs to be taken into account. No matter what aspect you study, you always need to be aware of those aspects. High fiber, low saturated fat,... means you get sick more often? While low fiber, high saturated fat,.. means you get sick less often. Whatever you say about fiber and saturated fat, it can't be the case that getting sick more often is the healthier way to eat.

Check out the biome of hunter gatherers, such as the Hadzas and Yanamamo, most diverse on the planet.

[@apocalypze83]

Hadzas diet consist of 70 percent plant foods. Looks like fiber doing it's job. Don't know much about yanamamo but looks like lots of fiber too. Go fiber tribe.

Isn’t the fiber argument the definition of healthy user bias? “People who seek more fiber for health reasons are healthier” Compare obese high fiber consumers with fit carnivores and let’s see what happens.

[@heidiharris1381]

Of course the studies be used by the Dr. will show fiber will benefit. The question is what diet was used for these studies. Usually its the SAD standard American Diet. You need all the help you can get when consuming SAD foods. Fiber will help to reduce the insulin responses from the SAD and help with the gut because of all the sugar and synthetic consumed. Also the other question is , did any of those involved in The study have diagnosed diseases like SIBO, leaking gut, or autoimmune disease? Oh , i forgot. Most of these studies where done on rats and not humans. There to many factors to address before sating fiber best. It may be for the SAD just because its horrible and mostly not real food. Sighhhhh

[@ChadCilli]

It’s hard to take Layne seriously. He doesn’t know the difference between diverticulosis and diverticulitis, and he’s not familiar with any of the research from Dr. Justin Sonnenberg. so, when he discusses gut Health, I take it with a grain of salt since he has no idea what he’s talking about, and it’s outside of his field of study. just like when he decides to comment on cancer and pretend that he’s an oncologist, he’s so far off base it’s actually kind of frightening that people look to him as an expert.

[@Ratchetti]

Ummm what 😅😅

[@ChadCilli]

@@Ratchetti he studied protein and leucine. You can go read his dissertation. He thinks that oncology experts are idiots about cancer, and he thinks that Sonnenberg doesn’t know anything about gut health. Just because you have a PhD doesn’t mean that you’re an expert on every single field. In fact, having a PhD pretty much requires that you focus on one single field of study at the expense of everything else. And when he debated Paul Saladino, Layne had no idea that diverticulosis and diverticulitis were different conditions. You can’t act like you’re an expert on gut health and gastroenterology, and then not know the difference between diverticulitis and diverticulosis.

I've tended to really like Dr. Norton's interpretations of the data. I've been a bit less convinced of Dr. Huberman, but I still feel he's doing well enough. Like you, I think he stretches interpretations, at times. Would love to do a video with Dr. Norton.

[@azdhan]

Just a couple of things I love Layne, find him to be one of the most reputable You Tubers , and I subscribe to his channel. Having said that if you search Simon Hill’s podcasts where he interviews some of the top gut microbiome researchers in the field, there seem to be differences in their views. One side says your gut microbiome bacterial makeup is pretty much established at birth and what diarupts their existance is exposure to SAD diet consisting of emulsifiers and other potentially additives and chemicals that kill off the bacteria. This also includes antibiotic use. So if you attempt to repopulate your gut with a cocktail of peobiotics and probiotics , it may not result in resolving the issue as your original strain of bacteria will always atrempt to repopulate and take priority. The other side says not totally true and consuming more prebiotic and probiotic foods like kefir, kombucha, kimchi, and sauerkraut can and will change your gut microbial makeup for the better and significantly improve your gut microbial makeup. There is also some debate as to why people have issues with fibre and probiotics or things getting worse. It is like the what came first tge chicken or the egg debate. Some claim that absence of fibre can cause some microbes in your gut to cannibalize your gut mucosal layer which can lead to leaky gut. Others say if you don’t have enough of a gut microbial makeup and you consume more fibre to start with, all that you will end up doing is p*oing the limited gut microbial bacteria as the fibre will act as a sponge. This long term can do more harm than good. Bro,now you understand why people can become so mistrustful and suspicious of Science and Research when even top experts in the field cannot agree among themselves and disseminate conflicting if not contradictory messages.

Short chain fatty Acid in Ghee and Goat cheese of course if the source coming from a good clean source

[@okaynope5197]

Didn't he just say saturated fat decreases gut microbiome? Why would you assume the net effect would be positive from ghee if there is no fiber for the biome to feed on and it is 50 percent saturated fat? Also the net effect on longevity from poor lipids? Fiber seems like a much safer option unless you have outcome data for your position.

I found Huberman's podcast refreshing in its infancy, but got an undeniable hunch that compelled me to unsubscribe when during one of his episodes he started talking about the characteristics of victims in muggings. What exactly is to be gleamed from observations like these? Who gets to benefit from the findings? Who is the research for; narcissists and psychopaths? On the contrary it would be prudent to expose the psychology of perpetrators: perpetrators attack the disempowered. This research exposes the wrong party. I have since unsubscribed and am not too surprised to learn that he does not in fact reject the carnivore diet. He shows poor judgement.

[@ThingsYoudontwanttohear]

I might have a good case for you to review. A few days ago a "documentary" started to pop up in my YT feed named 'Burzynsky: A cancer cure cover-up'. I have not seen it yet, but the red flag title and description makes my bs-senses tingle. You might know more about the subject and be able to distinguish fact from fiction. Btw: I forgot to tell you: Good job on this video. I learned a lot!😁

I'd love to cover it, but it's an hour and a half and seems like it would attract battalions of people that would just bash me for making any corrections.

Appreciate the suggestion, though - as always.

@@Physionic Your response is understandable. I also don't want to watch a (likely) conspiracy video like this one of 1.5hours long. However, maybe you will find the time to make an unbiased short video to explain the biochemistry of "antineoplastons" without mentioning Burzynsky too much. That way it might help drive some more attention to your channel from people that are searching for some clarity on the subject. Anyway, good luck on the backlog.🙂
