Although, almost their whole life was in Mexico eating a "one-ingredient" diet, which after all was remarkeably low in carbs, minus the occasional "rice and beans" sides ... they did fast extensively just because of the lifestyle here. They are in exceptional health, and were always at the top of their classes, etc. They loved fat and butter. :D The cool thing, Stephanie is that we know now. It's never too late.

Hey Paul, what’s your explanation on physiological insulin resistance when long term ketosis causes blood sugar to slowly but surely rise over 12 months? I reached Pre diabetic levels after a year 90-110 mmol. Do you think that’s normal? Or do you think the introduction of carbs at certain times of the year is the way to go to keep the body from becoming metabolically inflexible. Low carb, carnivore, keto is my preferred way to be but I think a lot of these lectures and presentations fail to mention the long term effects of high bg caused by the diet.

[@bijanbonyadi1787]

I don't know why he never mentions anything about this. I'm also concerned although ketosis is my preferred state to be due to anxiety and depression

[@juice1884]

Eat some carbs, man

[@7arik1]

Maybe you eat too much protein, Amber suggest you should be a Lipovore

[@shozby]

@@juice1884 yeah I’ve been eating fruit, starchy veg and honey to spike insulin, get my liver to down regulate glucose production and get the muscles to take up blood glucose. Problem is my body goes right back to ketosis or doesn’t even go out of ketosis at 100-150g of carbs! I might have to add even more. My theory is that i am highly fat adapted, ketones always 0.2, used to get up to 3mmol but slowly went down over 12months with no change in macros or protein amount which shows high ketone utilisation from the extended low carb lifestyle. I have a Physical job, do jujitsu and lift heavy weights every week which has my liver working overtime to produce bg for all of the anaerobic activity. I just want an expert to address it in detail.

[@spin564]

Oh my! Amber is the reason I ditched plants, and now this makes SO much sense it is, for me, the way to go. I never used to be able to eat most fat, yet after two years plant free I relish it. So eat carbs, make body fat, the more body fat we have the more it tells us to use it, a huge benefit in temperate winters..... Modern carb food is addictive, add to that the low fat dogma and hey, disaster. Done deal. So sad. Once again Paul, thatnks for posting, I will promote this hard!

[@johnchardine1886]

Many large carnivores preferentially eat the fat component of their prey rather than the protein component.

[@hisroyalblueness]

You're absolutely correct, most large carnivores firstly attack the gut of their prey, seeking out the liver, heart kidneys and the fat layers. I noticed that little area of poor focus but it didn't detract from thesis overall. Maybe the human ability, to smash and crush large bones meant that they had ready access to a wealth of bone marrow from the remains of large animals killed by others? I think that what she should use as an exemplar is the more recent Eskimo / Inuit diet which was essentially a seal blubber main with a side of raw fish. There never were healthier people . . . until they were introduced to the western diet.

Nice hypothesis on how stone cutting tools would have been a natural by product of using percussive stones to get to marrow.

This was very interesting and informative. Ive lost over 100 lbs on keto but I'm wondering now though, since I've been doing a mostly carnivore diet for the past year and a half (higher protein than fat) im finding it much harder to lose the last 60 lbs than when I was doing keto. I'm in mild ketosis but weightloss is very slow, i usually end up gaining like 10 lbs if I add any carbs in over the course of say a week. Then I struggle for a month to lose it again. I have vitiligo and I find veggies hard on my digestion so I'd like to keep them to a minimum. Do you think increasing my fat and lowering my protein could kickstart my fat burning again? theres so many conflicting opinions out there from different low carb docs with regards to eating too much fat and not utilizing your fat stores so I'm not really sure what to do. Any advice would be greatly appreciated.

[@whittlejoe]

Increase stearic acid while reducing linoleic acid. See Knobbe, and Saladino videos on KZbin.

[@sadrien]

I recommend sticking to a ratio of 1:1 fat to protein or higher (on the fat side) IE: 2:1 fat to protein. This is easily determined by making sure the ratio of visible fat / adiposites in your meal is >20% of the volume.

[@kassandraclinch3688]

More fat for sure. Eat high fat meat 30/70 ground beef is a great place to start. I use butter on the lean cuts (it’s a cheap solution for me - I can’t afford ribeyes) and don’t waste a drop. Eat the fat first and then fill on protein. A lot of people lose weight faster this way. I didn’t think it was possible until I tried it. Now I even like extra fat on my burgers and weight I’ve had since childhood is falling off - almost too easy.

[@bryanb3083]

Watch out for eating/drinking things that will spike your insulin levels, even in the absence of carbohydrates. Artificial sweeteners - aspartame, stevia, sucralose - will all increase insulin levels. Eating too much protein will also cause an insulin reaction. Insulin stops lipolysis (fat burning). It was hard for me to give up Diet Coke (sweetened with aspartame and acesulfame-potassium), but when I did my weight loss plateau ended.

[@GTE_Channel]

Switch it up a little try very high protein moderate fat and as low carbs as you can for a while. Search for P:E diet, I feel its complimentary to the keto approach. It's normal for weight loss to stabilize at one point, I do love keto but more fat is not always the answer, in my opinion. I believe switching between high fat and high protein is beneficial, that's my personal experience anyway.

Dr, I have a question about the low carb diet and testosterone level. Why do many carnivore dieters have a lower level of free testosterone and a higher level of SHBG than average lines? I've been on a carnivore diet for 3 weeks, and I'm worried about my T level.

[@andreafalconiero9089]

If you didn't know what your "T level" was, would you be worrying about it? The reason I ask is because people on carnivore diets sometimes fret about the fact that lab measurements of certain biomarkers happen to fall outside the "normal" ranges that have been established from those on omnivorous diets, and assume that this must indicate some pathological condition. It may in fact indicate a state that is physiologically *normal* for our species that is rarely seen because people in agricultural societies are not eating a species-appropriate, ancestral diet. The more pertinent questions are: how is your libido? your fertility? In the end, those are the parameters that actually matter when it comes to reproductive health, not whether particular sex hormones fall within a range that doctors (perhaps mistakenly) regard as normal.

G S BMI is not accurate for anyone who is not close to an "average" Western person. Better to use waist to height ratio. You measure your height and then you measure your waist circumference (half-way between the lowest rib and top of the hip). Divide waist measurement by height measurement. If the result is over 0.5 you're overweight. If it's less than 0.35 you're heading towards underweight. Anything in between is Ok.

The only thing that does not fit into the "we only need Meat as fuel"-theory is the point that we have glycogen-storages in every muscle and that just with glycogen we are able to get out maximal power. That's why for example the anabolic diet included "refeed days" to refuel the storages. Which at the same time does not seem to make sense to me, because the full glycogen storages are getting used for energy in the following 1-2 days and are already empty afterwarsds without really benefitting to your workout .. ? Can anyone tell why we have glycogen-storages and why these storages make us perform better, if we are originally just running on proteins and fat?

[@ekondigg6751]

Enn Dee Glycogen storage is short term only. It's good, even essential, for short term strenuous exercise, like getting away from a predator or enemy. It's not efficient in terms of energy density so the body only stores enough for such use. Longer term energy storage is fat, which is more energy dense but takes a bit of time to mobilise. So both are used by the body, complementary to each other. (The body can replenish glycogen stores without eating carbs because of gluconeogenesis.)

No mother should be harmed through her child, and no father through his child. And upon the [father's] heir is [a duty] like that [of the father]. And if they both desire weaning through mutual consent from both of them and consultation, there is no blame upon either of them.

[@nicholastidemann9384]

Great theory; except it is in blatant contradiction with everything we know about human biochemistry. www.quora.com/Why-can-t-the-brain-use-fatty-acids-for-fuel/answer/Israel-Ramirez «Why can’t the brain use fatty acids for fuel? The answer to the question tells us something about the disadvantages of oxidizing fat instead of carbohydrate. [...] Summary The brain doesn’t oxidize very much fat because doing so is harmful, partly on account of increased production of superoxide, a substance known to injure cells. Mitochondria don’t work as efficiently when they contain large amounts of fatty acids. The brain is uniquely susceptible to problems of this sort because it has a very high rate of metabolic activity and cannot afford to let neurons die in the process. This high rate of metabolic activity also means that burning a substance, fat, that increases oxygen demand isn’t a good idea.» The brain is never "starving for ketones"; the brain absolutely detests having to rely on fatty acid oxidation for fuel. It has an incredibly strong preference for simple sugars. Also, long-chain fatty acids don't even cross the blood-brain barrier, which makes the problem even worse. Anyone who tries to argue that the brain prefers to run on ketones literally needs to get their own brain checked, and not surprisingly. This also means that cholesterol doesn't cross the blood-brain barrier at all, a fact often glossed over by advocates of exogenous fat consumption. That means that literally all the cholesterol in the brain is biosynthesized de novo in situ from products of the citric acid cycle, which again, works optimally on simple sugars; yet another reason for why the brain has such an incredibly strong preference for carbohydrate.

That figure is surely way out, and good luck trying to consume 200g of fat with bugger all else really...(at 10g carbs I'd go carnivore you'd probably get that from 6 eggs and 100g of liver...) I thought Ketogenic was closer to 5% Carb/20% Protein/75% Fat ??!!

Maybe this was a bit misleading, but she mentioned (and the text in the slide said it, too) that this extreme keto example was for therapeutic treatment in cases of epilepsy. So I would agree that "normal" keto would be more in the range you've written.

@@kstoeb yeah and I heard back when they would prescribe these therapeutic numbers, they would have the patient hit the fat macro by drinking vegetable oil, so not really good
