Great lecture, thank you so much for honestly educating people

[@ashleymccracken]

I believe you dabbled in the carnivore diet. Do you now think that you need vegetables for probiotics? I'm asking because my husband is 7 months into his carnivore diet and all of his auto immune conditions have cleared up and he has lost almost 30 lbs, is stronger at the gym and has never felt better. So I am trying to wrap my brain around why he seems to be doing great but his autoimmune conditions should be full blown because his gut bacteria should have long eating his mucus protecting his intestines. I have crohns disease and have done the carnivore diet twice for 30 days each and I didn't flare up and my other autoimmune issues improved. Just like everyone here, I am trying to navigate all of this information from you, low carb down under drs and speakers, Mike mutzel dave feldman, Shaun Baker and many more. And of course make sure we are getting healthier rather than unknowingly sicker.

[@dmackle3849]

@@SulthanMuhammad she’s saying that, but it might not be true in all cases. I suspect Pat is taking issue with the assertion that sufficient fibre is NECESSARY to maintain flora. Thus theoretically sparing the mucus layer and preventing gut content coming in contact with internal surfaces that trigger an immune response in which the internals become collateral damage. Many 100% carnivore (~0% fibre) are not finding this theory to be borne out in practice (unless there is an animal derived fibre substitute not yet accounted for). As per the last section of the lecture the devil may be in the details of the exact diet. Which is best of well managed some fibre vs well managed no fibre, and is it depending on the exact microbial spectrum and the individual? Possibly the sensible approach is to bias the diet to enable microbes that won’t resort to cannibalise the mucus layer that go ahead and outcompete those that would cannibalise: before going to zero fibre. Or at least understand and minimise components of the diet that might be present and promote an immune response during any mucus depletion phase. Carnivore seems to present little challenge that results in an immune response. Transitioning to or from, probably requires a robust strategy to avoid any inadequate defence condition that cascades toward bowel illness.

We have a very small cecum and a useless appendix that aren't designed to be fermentation chambers like ruminant animals are. Carnivores have no issue with constipation.

I agree this video and others like it are essential and needed. Obesity and inflammation, though, can start early in childhood before we have control over what we eat. I don’t know any children who do the shopping and buy the groceries. Babies sure don’t. No control. Diet during pregnancy affects fetus, and breastfeeding or not affects infant, baby food choices affect toddler, and so on. My mother followed the government Canada Food Guide. Who knew back then in the 1970s, that the diet was based on Ancel Keyes flawed and cherry picked study? If a baby/child had Celiac Disease and fed pablum and later toast, crackers, cookies, first birthday cake, then their gut will already be compromised. By the time you figure out the problem that person could be consuming an inflammatory food for 20-30+ years. Many never realize until too late. My friend with Celiac Disease was never diagnosed until she was 60+. 60+ years of damage and suffering. It would have been even longer if she counted on her doctor to figure it out. Or for economic reasons, parents could only afford cheap food products. Or war time nutritional depravities stunting growth, and causing damage later on if they did survive. Not everyone has a cell phone or computer to access information. There are more organized vegan information sites for those looking to improve their diet than low carb/keto diets. It doesn’t help people still don’t realize doctors have no proper correct nutritional training, or even dieticians who are required to preach the gov’t approved high carb diet. Because of this, there are an enormous amount of people suffering out there. We need to organize better access and share the information; these presentations are vital to give more people healthy options to prevent chronic diseases, complications from disease and show that a lot of current information out there is misinformation. Independent studies need to be done right. It is slowly getting there, slowly.

Days after consuming them, my digestion was completely out of whack, I felt like crap, I was bloated, I felt like I wanted to puke, and I never lost weight for almost an entire week despite having 2+ month history of consistently losing 4.3 pounds per week on average with keto. Now because of that 1 failed weight loss week, my average has tanked to just 4 lbs per week, and I will never consume such noodles again.

First of all, it's ok to have a bad week. You will not continue to lose 4 lbs/week realistically closer to your goal weight. We all need to adjust how we see food and measure progress. As someone else said, fiber is carbs, so it's important to consider total carbs and net carbs, as some foods manipulate fiber content to decrease total carbs, think quest bars. Erythritol makes me bloat for five days after consumption, but once the bloat goes, my weight also caught up to previous losses. Your use could be straight up fiber, the bloat or a quantity consumption issue, or even the lye product it's put in, or other ingredients touched in the factory, like gluten or soy.

About a third of the way thru this vid I realized that she was not talking about humans. She's talking about gorillas. We have a carnivore digestive system. Our stomach is an acid wash meant to kill all bacteria in the swallowed meat. Our system is not meant to ferment fiber and turn it into saturated fat. That's what herbivores do, and a gorilla is a herbivore with one small difference. Herbivores have an alkaline wash meant to kill only some of the bacteria, because they need the rest for microbial fermentation of fiber, since most of their energy comes from saturated fat converted from fiber. Gorillas have a higher acidic level in their alkaline, because, being omnivores, they include bugs with their salads and fruits. Humans do not have an omnivore pH wash in the stomach. Our pH is 63 times greater than the gorilla pH. The reason our pH has remained so high despite millennia of plant inclusion in our diet (which causes all of our innate diseases) is our brain, its size and energy needs. We can't afford to be omnivores if we want to remain homo sapien and not become homo dumbo. We have no business putting fiber in our stomach. It ferments because fiber, and all plant life, is fundamentally sugar. We get the glycogen we need from a carnivore diet. Added sugars and carbs (and carbs are practically all sugar) are toxic to us. So ignore this girl's talk unless you're a gorilla or would like to be one.

[@DougHNuts-ee3vn]

[@bigtimbers9025]

Then can you please explain why so many studies find fiber to be very beneficial? Also it is fairly well established that we do have some light fermentation that occurs in our GI tract, but this is dependent on what you eat and the bacteria that are present. Also, there are some great studies comparing out GI tract to other predators that find most predators that eat meat have short GI tracts and creatures that eat mostly plants have long GI tracts to allow time for fermentation. Humans fall into the latter. Scientists are finding more and more that our ancestors most likely ate tons of leafy plants with occasional meat or dairy that they could acquire(personally I think they had to eat what was available to them which doesn't prove what the best diet is). While nothing is super conclusive yet, it seems safe to say our system is built for flexibility.

[@piiiiiiiiiina]

www.kevinstock.io/health/what-did-humans-evolve-to-eat/

[@Nmyers91]

BigTimbers our gi tract isn’t very long especially our long intestine which is where fiber is fermented. We also have a low intestinal surface area. The main benefits of fibrous foods are from the carbs and processed foods they replace. Our ancestors ate at least 70% animal foods for most of our evolution and likely more, with most of the plant food used for energy when fatty animal foods were scarce.

[@williamdavidhilton6659]

@@piiiiiiiiiina The length of the intestine is not the issue. It's the diameter. Humans have e a small diameter intestine, meant for nutrient dense foods, which means meat. You can sterilize the colon and do just fine. You can remove the colon as well, with no adverse effect on digestion. Apparently you haven't heard of "animal fiber." This is the small amount of undigested meat that can be fermented into butyrate. The body can make butyrate from amino acids. Plant fiber can add too much butyrate, which then damages the mucosal wall of the colon. Paleolithic man was a super carnivore, meaning he not only ate herbivores but also ate other carnivores. Paleoanthropologists can determine the the diet of any animal by using steady isotopes of carbon and nitrogen in examing the skeletal remains. This method shows that man was exclusively a meat eater, since there is no evidence whatsoever that plant material was part of his diet. (Though almost certainly he ate seasonal berries, but that's just a guess.) Where you got the idea that man ate "tons of vegetables" can only be a propaganda site full of psuedo science. You should broaden your research, preferably without ideological bias. When I wrote "high pH" I meant high acidic levels. Humans can generate a pH of 1, which is the most acidic stomach wash of any carnivore. If your digestion pH is at 2.5 or higher it is too alkaline and your microbial colonies are too numerous and diverse, giving you a greater risk of GI disorders. It has been conclusively shown in animal studies, using mice, rats, guinea pigs, chickens, and dogs (which have virtually the same GI system as humans) that animals do not require gut biome for good health. In fact, "sterilized" animals have greater longevity than non-sterile members of their species. Problem is, we can't prevent the bugs from getting in. But we can keep their number and diversity at a minimum if we maintain the proper carnivore pH and diet. Now let's take a look at the ancient Egyptians, who were called by the Greeks "Eaters of Bread." This was post-neolithic, well after the rise of crop agriculture. Egyptians had a very high carb diet. Autopsies of hundreds of mummies, and the evidence of medical reports found in papyrus sources, show that the Egyptians were riddled with arthritis, diabetes, and chronic cardiovascular disease. And looking further, we find that since the neolithic age man on average has suffered a decrease in the following: brain size, height, bone density, and overall health. Crop agriculture has stalled our evolutionary development. We're heading back to the trees.

Great talk, can you shed some light on yogurt how many carbs should we be counting from plain yogurt? I have seen onion on the list of the vegetables but are they not carby and should be eaten in small amounts? What if i eat more vegetables from the green list and exceed my net carbs limit am going to fall from ketosis

[@rageonyx]

Hassan eat as many green and leafy vegetables as you want. As long as you do not make juice out of them, you can eat them non-stop all day. The vegetables that are not good to eat for ketosis are the ones that are not green and grow under ground. Carrots, onions, potatoes, beets... all have too much starch and sugar. You can still have some, but very very little.

[@johnnypenso9574]

^^ Sorry but this is bollocks. Use an app, weigh your food, read your labels if you have them, count your carbs (net carbs) To get into ketosis at first it's best to go low 20-25. You can start experimenting with higher numbers later on, after a month or two. Try 30 for a month, then 35 etc. As long as you hit that target it doesn't matter what carbs you eat so long as you stay under your target and it's possible to easily go over that target eating a couple of large salads if you also eat avocados, nuts, seeds etc. The problem with carrots, potatoes etc. is that you can only eat a very small amount and it'll put you over your limit, but it doesn't mean you can't eat them if you really want to. Weight, measure, count, stay under your target.

isn’t it fascinating that stool transplants not only make you better but don’t disrupt the body. you’d think, given the nature of excrement, it wouldn’t be a good idea, and yet it works.

[@diablominero]

Short chain fatty acids cause Parkinson's in genetically susceptible mice. That's obviously not necessarily generalizable to humans, but I think it's worth at least being cautious before declaring them good.

[@doug5421]

Zero fiber, moreso zero carb, is the best approach. We were never designed to eat plants, that’s what our food eats.

[@LurkingCrassZero]

I half agree. I think the natural rhythm is for us to feast on more raw foods, carbs, fruits during the warmer months, seasonal fruit & veg etc, gaining some body fat. Then switch to a more ketogenic, cooked, high fat, lower carb foods during the cooler months, with periods of fasting here and there in winter. We're not meant to be in ketosis all the time. It's our backup survival mechanism.

[@FordyHunt]

That's not true, we can live without plants AND without meat. We're omnivores. Cows as an example are not designed to eat meat, and con not live on it.

[@jagshemashsagdiyev5966]

All the available evidence points to plants being pretty damn important. In fact, that's all we need.

Hey, how about addressing her points specifically? 'twould be a refreshing change from your beeswax.

really? what part of our digestive systems point to us being carnivores besides our pathetic little 'canines' ? From my own research it seems our digestive system has far more in common with herbivores.

finally a lowcarbdownunder that recognizes the importance of fiber..wish i had seen this years ago before going on low carb diet..ate high fat.. high protein..low carb ..no grains..now have cad..cardiovascular disease..arteries full of calcium deposits..now i have to make sure i consume minimum of 30 grams of fiber per day to stay alive

Every time she uses the word "evolution" we can insert "nature" and it makes her statements factual.

tl;dr version: Eat your veggies.

[@masonmmjmu]

I have to disagree. There is an abundance of research supporting increased fiber intake with longevity and gut health. Increasing animal protein intake from the wrong sources (grain fed animals, additives, or antibiotic induced) is going to lead to inflammation that can harm the microbiome and thus lead to possible weight gain. I love my meat, but it has to be balanced and chosen carefully from the right source. Eating mainly protein and too little complex carbohydrate (that takes out fiber) may help someone stay "thin" but it will not increase your life expectancy or quality of life in the long run.

[@WaitingForTheHook]

This is all wrong. Have a great day.

[@DougHNuts-ee3vn]

I don't agree with the carb intake part in Fiber Menace but I am enticed with raw carnivore because I did that for a short while and the results were amazing. I just got scared about it and quit.

Too complicated. Where would ancient man get fibre all the time? Wild fruit n nuts once a year perhaps. Eat raw meat don't worry be happy. 😊

Eat lots of veggies! Broccoli , peas, brussels sprouts. Ditch sugar and refined carbs. Keep insulin low!! And ...eat fewer meals...no grazing! No fruit juices either!

[@louisacapell]

G. Moore thats actually horrible advice for people with gut inflammation or infections ( which is a lot of people) SIBO , diverticulitis, colitis and many other issues are made horribly worse that way. Meat, butter, salt is the best way to heal the gut in this case.

[@Bodybypt]

Most people do better with less veg

[@swissladydriver8980]

No thanks to the Broccoli, Peas and brussels sprouts.No one Needs all that gas.

[@Aria-Invictus]

Unfortunately for the HFLC peeps, going keto will just cause you to cause you to break down protien into glucose. Ingesting more protien wont help since the process is highly inefficient, and the protien causes a rise in insulin anyway, especially coupled with fat, making you more insulin resistant. HFLC peeps arent aware intramayocellular lipids which causes IR. Fiber can cause gas depening on your gut flora. If you eat more meat it will only shrink the population of bacteria that can handle the fiber in favor for those that cant. Anyway gas is a small price to pay vs raising you all cause mortality rate. HFLC peeps, ask yourselves why arent there any centenarians that eat a primarily meat based diet? Zero.

[@ellenorbjornsdottir1166]

you're lying to yourself if you do not believe there are centenarians (or at least vigorous nonagenerians) who avoid the regular consumption of carbohydrates.

Dear Erynn, your presentation starts with beautiful fairy tail: 'In a rainforest, it's a beautiful. Peaceful. There are animals, plants, microflora.

[@marcierenee15]

My c-section son is far healthier than his older brother that was born vaginally. He was given a probiotic rich formula and his first food was yogurt. A day does not go by he doesn't eat a yogurt or two. His older brother was nursed well past two. C-section son his perfect digestion, amazing energy, strong athlete, super high metabolism. First son has been plagued with IBS and chronic cystitis since his youth, plagued with anxiety and depression, low energy and easily sick. SO- in my case my c-section son that had probiotic formula thrives while my vaginally born son that was nursed has the health/mental issues. Doesn't make sense, does it?

[@ellenorbjornsdottir1166]

Maybe increase probiotics in mr v-birth's diet if he likes them? Or change him to low-fibre since IBS is a fibre disorder

[@craigslitzer4857]

It could be that the mother's health or specific environmental variables factor greatly into what delivery environment a baby is exposed to. Very possibly a prerequisite before a baby can receive the benefits she alludes to in her talk.

[@sw6118]

Only one of my brothers was breast fed (both were c-section) and right from the start he has had a lot more issues with illness and obesity. Clearly c-sections and breastfeeding are only part of the picture. I sometimes think the entire c-section/breastfeeding arguments are really all about blaming the mother because doctors don’t have a clue and will seldom own up to ignorance.

[@marlenegold280]

Test their 25(OH)D, get the results in ng/mL or nmol/L and compare. Ask doctor for copy of labs; it is the patients legal right. Test with same blood draw iPTH Serum calcium just to rule out Parathyroid disease. Optimal 80 ng/mL 200 nmol/L Most people are Vitamin D3 deficient and have those symptoms you mentioned.

There are literally thousands if not hundreds of thousands if not millions of different confounding factors/variables, including what you ate while pregnant or months leading up to it.
