*1 AMENDMENT* AMENDMENT: Someone pointed out that my assertion that pooping more frequently does not necessarily mean improved health. Upon reflection, and with some excellent examples offered to me, I agree - it is incorrect to attribute stool frequency as a necessarily 'good' outcome, so long as a person reaches the minimum frequency for maintaining health. Thank you to Albert Manson for the correction! Nuance, a lost science in KZbin science...

Maybe it is not so much about 'gut in very bad state' but maybe different people respond differently to different diets. Some cope with fiber and others don't. My mother eats a high fiber diet, has bowel issues swapping between diarrhea and severe constipation, also has diverticulitis. My wife is vegetarian and regularly has constipation. I'm almost exclusively carnivore and never have a problem. When I was vegetarian/vegan I had IBS. It was worst when vegan.

Some studies (mentioned in the gut health video I posted in the other comment) of people with healthy gut biome did show no change after they followed no fiber keto diet for a year, so I think fiber has it's place but it's not like we need to constantly feed ourselves with it if we are otherwise healthy.

Masais and Inuits didn't eat a lot of fibers either and they were perfectly healthy. So all this fiber propaganda is probably just a narrative to make us eat still more plant foods. If fibers look good in epidemiology it's due to the fact than people who eat a lot of vegetables and fruits (and thus fibers) tend to eat less ultra-transformed food.

I'm not exactly having one bowel movement per day, sometimes there's one or two days between bowel movements, but then it doesn't feel like being full of it, I would guess that without that much fiber there just isn't that much stuff to push out. And I have tried increasing fiber - It Did Not Work, quite opposite.

This was not addressed in the video but my life-long) constipation issues were completely resolved after I followed my new doctor's recommendation to increase my water intake. From age 10 through 60 I had severe constipation and no drugs or (food) diet changes had any impact. Over my lifetime my various diets were sometimes mostly meat and other times high in fruit/fiber but no relief. My long time PCP retired and I saw someone new. He suggested trying to significantly increase my water intake. I increased intake from my lifetime average of about 60-80oz/day to an average of about 150-170oz/day. I made no changes to my food item intake but within a few days my bowel movements went from lifelong of about once every 5 days to about 3 times/day. I have maintained that level of water intake for the past 7 years (except for one short experimental period - see next sentence) with the noted improvement still. As an experiment about two years ago I reduced my water intake back to the approx. 60-80oz level and within a few days my bowel movements began decreasing back to once every few days. That experiment was sufficient demonstration of the positive impact so I resumed 150-170oz consumption and back to my improved bowel situation. One caveat and warning is that all my life I have practiced high intensity aerobic exercises (5 days/week) so my water needs are much greater than the average person. Practice great care when increasing daily water intake to avoid negative impacts of overconsumption.

I solved my guts issues with lacto ferments. Following Innuit and mongolian diet with fermented meat or dairy.

Dr Paul Mason is absolutely right. His comments about fibre has been taken out of context - u need to be eating low carb/carnivore diet and u wont be needing the fibre. Fibre is absolutely needed when u are eating the 'well balanced' meal plan which has resulted in so much problems. Paul Mason is excellent

[@Jayla-dj2gj]

Once your immune system/ gut is messed up you aren't able to take in much fiber. It's not that fiber is bad just that some people can't tolerate it and others can eat a ton of it no problem. I know my gut is messed up and I only eat small amounts or I get symptoms. My mom has eaten beans every day for decades and has no bloating or constipation. I think we need to ask why do we have bacterial overgrowths when eating fiber what is it that keeps bacteria in check and how is this system broken.

H pylori and candida might affect fibre sensitivity

[@dionysusnow]

Bingo! it's a dysbiosis.

[@jennysiepka9900]

[@Murgot73736]

Fiber is still non essential and you can’t breakdown the fiber one bit. What is the uplift of having to pass large stools often vs small ones not so often on a carnivore diet? The body takes up more or less every bit of the meat and fat and the only residue is bacteria and epithelial cells. Daily of when needed. Big volume stools just put pressure on your colon. I’ll bet that is the road to diverticula disease.

[@goranhemstrom3355]

Totally agree with Dr Mason! Was predominantly vegetarian for 27 years. Was not really a smart move! And stupidly kept following it for so long. Weight fluctuations over all those years and bloating after most fiber rich carb loaded meals. Just thought it was normal. Found a picture of myself from the ‘90’s and thought what did I eat then? Predominantly meat! Switched to Carnivore in late Feb and have easily lost 13kgs, not had a single day of bloating and toilet time is perfectly fine.

[@midwestcarnivore1857]

Since going carnivore my digestive system is happier than it’s ever been-no more bloating and gas. After a routine colonoscopy, the Dr. said, “Your colon is pristine. I’ll see you in ten years.” Meanwhile, my vegetarian husband had to have several pre-cancerous polyps removed and needs to be monitored more closely. My vegetarian mother has IBS and other gut issues, which keep getting worse. I realize that three people do not constitute a proper scientific study, but as someone who’s been vegetarian, carnivore, and in between, my personal experience is that I feel better eating meat. Blood work and other health markers (triglycerides, blood pressure, etc.) are also all improved since eliminating most fiber from my diet. Maybe it’s not for everyone, but it’s working for me. 🥩 💪🏼 😊

Now, no meds and no acid reflux! I don’t know if the fiber had anything to do with it, but before I went on meds (nexium) my reflux felt like a heart attack in the middle of the night. It would wake me up and keep me up all night. Now - zero refux, zero pain, and at 73 I feel great.

I now have reversed all of the above symptoms by eliminating fiber. I eat the correct amount of protein and fat and have perfect, daily bowel movements.

[@christopherl4249]

I am sure you have heard about blue zone study. Years ago, Dan Buettner wanted to find out what regions of the world had people who had exceptional longevity and what their secrets were. Unlike Dr. Mason, Buettner had no agenda to promote any specific diet before he started his study. Among the factors listed (there were 8) is a plant based (high carbohydrate) diet (90% or more). What would have happened if the research had come up with the opposite - a high animal protein diet as a factor for longevity? You can bet people like Dr. Mason would include the “Blue Zone” results in every talk he gives. A great majority of independent studies (studies not funded by the egg council, McDonalds, the dairy industry…) conclude that consumption of animal products increases the risk of diabetes, heart disease, and cancer. Why weren't these 90+ and 100+ year olds suffering from gas, bloating, and other gastro-intestinal problems? And it appears that there was no "fiber dogma" among these people, nor did they go out of their way to consumer fiber. It's amazing that the people on the carnivore diet have only their own anecdotes. Remember doctor Atkins - one of the early promotors of Keto and meat based diets? Well he felt great too, right up to the point he died of a heart attack at age 73. Of course the anecdotes we are not hearing about on this comment board are ones like Dr. Atkins.

Yes but what were you eating though. If you are eating bread and cheese, chicken breast and veggies and not enough water or fat... it will absolutely cause constipation. If you eat low residue ( ie; butter, fatty fish, fatty red meat, rugs etc) you would not need fiber supplements.

Fibre (prebiotic fibre) feeds the good bacteria in the gut and improves gut health, adds bulk to the stool by absorbing water as it passes through the digestive system make it easier to pass. Improving your gut health means food gets digested better so that it does not cause leaky gut, IBS etc.

He stated in the video that this criticism doesn’t completely invalidate the results of the study. He said he believed the results. It’s just important to point out that the study lacks important information that limits the inferences we can draw from this particular study. It’s also important not to get stuck on studies in isolation and instead look at the overall balance of evidence on a given topic

[@Mallchad]

​@@clarebagsYes. The genetics and studied on that are that which informs us we physically lost the ability to process fibre when we diverged from the great apes and homonids species. Coincidentily this means no human (homo-sapien sapien) on Earth can digest fibre in any capacity. There is some (significant) wiggle room when talking about dairy, gluten, tubers, and other things. Some of this is genetic, some of this is environmental, some of this is environmental triggered genetics. Ruminant meat seems to have a very high tolerance in 99% of humans but it difficult to test because it requires a large scale experiment of people eating nothing but meat...

If you do an overview - it's clear that fibre is largely beneficial for digestion (but obviously there's nuance to this - and there may be some individuals who would benefit from reducing total fibre or focusing on the TYPE of fibre in their diets)

The reason why some people benefit from going carnivore is because those people have dysbiosis in their gut microbiome, usually from so past usage of antibiotics.

I’ve been on a carnivore diet in the past. I was able to get rid of the bloating and digestive issues after a couple months. But… I was dogmatic with my views as keto and carnivore was my entry into the health space. I then opened my mind and looked at the revolving studies around the gut microbiome and the importance it plays on that whole body. I then started implementing a pro-pre biotic supplement, and saw even further improvements in my overall digestion. Then I started to add small amounts of fiber from fruits and vegetable. I did get bloating and gas at the beginning, but slowly ramped up how much I was eating. I also exchanged the probiotic supplement for home made water kefir, which also helped with the overall digestion with the new fibers, providing the proper beneficial microbes to break down these foods. I started feeling more energetic and less bloated and left overall more satisfied with my diet. I haven’t measured how much fiber I consume daily, but I’d say I’m getting around 30-40 grams of fiber a day and have little to no digestion issues and have seen increases in my overall mental functioning when it comes to focus and sense of well being. I think when it comes to fiber, if people have messed up microbiomes from previous diets including hyper palatable processed foods and from other negative lifestyle factors, any fiber will feed whatever good and bad bacteria within your gut. And for most people, there’s more bad bacteria already in the first that will over react to these fibers resulting in negative effects rather than the beneficial ones that we get from some strains that produce short chain fatty acids. This is all speculation but it would make sense.

When I consume fiber, I have bloating, gas, cramps, diarrhea, etc. It can get so bad at times that I miss out on travel and/or social engagements because I'm practically housebound for fear of not being able to go to the restroom when I need to. But when I eliminate the fiber, symptoms decrease and eventually disappear altogether.

I looked up the study and it also says fiber didn't help relieve pain which is a common problem associated with constipation. There are also many other meta analysis on fiber intake, some of which show benefits but every single one cautions things like "data subject to high variability" or "strong indications of bias in study". I wouldn't trust those studies, and the actual data isn't statistically impressive at all. Increasing stool frequency isn't a good thing either. Who cares if you run to the toilet more often if one of your symptoms is constipation, pain, etc.? There are other studies that show the more fiber people consume the worse the outcomes are on a variety of issues. Check IBS, IBD, Chrons, and colitis studies for more relevant information. You can't appreciate how worthless fiber is until you consume none for a long period of time, like going carnivore. Fiber is not helpful in my opinion in any way whatsoever.

[@MrMeat_eatmeatliketheelite]

Why would you want something ,fibre, in your colon to holds onto water. The whole job of the colon is to absorb water. From an evolutionary perspective it makes no sense to consume something that holds onto water. That would be working against yourself. Secondly why consume something that irritates the colon. Again this makes no sense. The colon wouldn't evolve to work better in an irritated state. What matters is fat. Fat makes the stools soft and passable gently. To much fat will cause diarrhoea. In the absence of disease its the amount of fat that is key. The third point I would make is that fibre will block the absorption of nutrients all the way through the gut. From an evolutionary perspective it would make no sense to consume something that blocks nutrients from being absorbed. We wouldn't evolve to waste nutrition in that way. On the point about the study and high and low fibre being ill defined thats fair. But zero fiber is zero. And that is the group n=41 that all had complete resolution. That is the salient point. Finally it maybe the case that some fibre is less worse than other fibre. Soluble vs non soluble but that isn't an argument to eat fibre in the first place.

Increased stool frequency IS NOT the same thing as cessation of constipation. Constipation is stools that are hard, dry, or lumpy, difficult or painful to pass, or a feeling that not all stool has passed. Also in there is fewer than 3 stools a week. Increasing trips to the bathroom beyond that is not an "improvement". Yes, if you put more stuff you can't digest into your diet, you go to the bathroom more. The study Mason talks about is interesting, but you are correct in that it's not a well designed study. At the end of the day though, considering every participant suffered from a lot of symptoms, the fact that all symptoms of the zero fiber diet ceased, that is actually damning in it's scope. I get it, the study could be better, but the results of the zero fiber diet are insanely good. Maybe they didn't change anything else about their diet except fiber, or maybe they did. But not being sure is not the same as assuming they made other changes. This is one of those videos that is like, "I'm gonna toe the line and talk only about the science", but you literally discussed nothing else about the other studies that show benefits in fiber. You spent more time discussing what you didn't like about the one study then you did about all the other studies combined, you simply showed results. This also in the face the Paul Mason didn't hold this study up as the end all be all, but he did say that he follows the logic of that study with his patients and has seen large improvements in his own patient population who have issues with constipation. I probably eat about 10 grams of fiber a week, and my movements are consistently good. This coming off of a having constipation issues and trying to solve them with a high fiber diet. I used to eat 60 grams of fiber per day. I ended up with little more than extremely hard and large stools, and ultimately ended up with a hemorrhoid issue that has followed me for years. And once you have a bad hemorrhoid issue, no amount of dietary change makes a difference. No matter how easy my bowel movements are, I am still left with discomfort. I only wish I stopped eating fiber a lot sooner.

As a Dairy herdsman over a good bit of my life, I realized in my 20's that animal nutrition was much better understood than human nutrition, and I'm talking the 1970's here. Find a copy of "Feeds and Feeding" published by Morrison, first published in 1917 and updated regularly after that. One issue that I think is very important, based on my personal experience in feeding cattle of all ages as well as my own diet, is the need to understand the time it takes for the microbiome to adjust and normalize to whatever the foodstock is. Changes to the foodstock can cause profound changes in the microbiota. Stabilization of the microbiota must certainly take some days or weeks and must be considered as very important. Keeping a certain "consistency" in my diet has been important to minimize things like bloating and discomfort. My staple is legumes, not grains, and should I make a switch from one to the other there will be some noticeable issues until my system normalizes. If I throw in the occasional day of travel, for instance, where grains are about all that is available, I will have issues, not severe in any way but I will notice them for sure.

For reference these core daily foods of mine are whole grain and grain fibre products, vegetables, fermented foods and dairy.

It produced massive amounts of anxiety with frequency issues being the main concern to the point where i considered leaving my vocational field due to its requiring me to travel. Travel had almost become a deal breaker. On a chance discussion, i decided i had only one option left and that was to cut out every single source of irritants, including fiber. I reduced my diet to nothing but fat and animal protein and now i am essentially 90% healed mentally and physically. It is unlikely that i will ever eat a food item containing fiber again.

[@Sobchak2]

How did you test gut diversity?

[@heatherschramm]

Yes that is my question as well. I have always struggled with constipation and went on to develop SIBO for several years, which led me to eliminate fiber because it eliminates the symptoms. I have had multiple tests of my gut bacteria and it’s not been great, so I have worked very hard to get my gut better so I can consume fiber again and get my gut bacteria in good shape, and my understanding is that fiber is what feeds that bacteria. Really would love to hear that people who feed bacteria less have a diverse colonization. After all regular pooping is not just great in itself, but it’s a proxy for good gut health, which can be more directly measured by bacteria and gut lining quality.

My father had a Helicobacter presence in this upper GI tract, which caused him problems (bloating, cramps) when eating fruits. After taking anti-biotics for a while, he could eat these fiber rich fruits again. Without going into specifics and conditions of these patients, the results don't tell you anything conclusive.

I just started keto about 2 weeks ago, My ketones are in the upper 2's so I'm restricting carbs. On my normal diet I was having bowel movements everyday. But when I started keto I was going once every other day, then once every 3 days, then I got impacted stool. I was eating 40-50 grams of fiber before. Now I was below 20 grams even though I did my best to get in fiber and keep up my fat. The pain wasn't nice. I had to go fish the feces out of my arse but I still couldn't get it all out and ended up bleeding. I was about to quit keto. I thought maybe if I eat more fiber it will help. So I ate half a cup of wild blueberries and some cooked spinach and the this morning it came out. Here it is an hour later and I'm still in pain. So I will increase my fiber as much as I can to keep me from going under 1.5 ketones. For me keto isn't worth the pain and discomfort if this becomes a normal thing.

If your heuristic for gut health is the number of bowel movements you have then of COURSE fiber supplementation is going to increase those numbers. So would eating a handfull of gravel each morning. The problem is that the supplements increase your NEED for bowel movements over what they would need without them. When I am on carnivore I will usually have 1 or two BMs a day (a fatty meal like brisket will induce a second one), small in volume, and pass quickly. When I am not on carnivore, I have one per day in the morning, with much greater volume and take a long time to pass. I also have gas and bloating (I was the farty kid in school). When I am not on carnivore and take fiber supplements I again have two BMs per day and they are equally as slow and uncomfortable. More gas. More bloating.
