He's a natural person to become popular considering the promotion of high-protein diets and misinterpretation of research on fructose. The truth is that there is lots of evidence high protein diets can be harmful and no evidence that fruit is harmful (purified fructose does not equal fruit). The truth is you don't need much PUFA, though I'm not sure PUFA from natural sources will be proven harmful. People are flocking to Peat because they have bad experiences with high-protein diets. Unfortunately, he's just as much of a charlatan as the rest. His evidence that vegetables are poisonous is complete misreading of the studies he cites.

I think Peat is mostly kind of a wackjob. I sites really old editions of encyclopedia brittanica and funny little websites as citations, so he kind of misleads as to the quality of information backing claims.

That said, many of his articles are at least funny to read, so I'd go through them at least once. Just not as a serious "wow I should eat a quart of ice cream everyday" advice source.

I spoke with him on the phone a couple of times (Ray Peat) and I asked him point blank about sugar. He thinks it is a very clean, good substance. He advocated ice-cream as a good source of calcium and good sugars. I never understood exactly his theory of glycination. He believes that you need to keep your blood sugar up. He is especially fond of orange juice. I bloated up to 230 pounds, which was ok at the time since I was bulking for my weightlifting, but would not be a good idea in general.

He advocates coffee is a way of boosting your metabolism. I tried this and, honestly, for the first time in my life I had high blood pressure. I probably am extremely sensitive to caffeine, though to be honest.

I think he has some good ideas, but I find him quirky. I don't have the background in physiology to get one-on-one with him. He's a smart guy. However, I was not too pleased with the results. That's what I have to go on.

I like the 'ol bastard. But mostly as a check against what others say.

He cites evidence, but not comprehensively. In other words, he seems to only approach one side of the story sometimes. His article on vegetables did not have a real conclusion-- we breed vegetables for food that are safe for us to eat, for the most part. This is not addressed by him.

Fructose is a hepatotoxin, like alcohol. It has no effect on blood sugar or the insulin response. It is fine in fruit, as the fiber of the fruit that comes along with it keeps it in check and makes it more difficult to eat large amounts. Fruit juice is worse than regular Coke.

Vegetables give us fiber and minerals without fructose.

This guy sounds wacky.

Someone just post a list of what he says to do so I can do the opposite.

On that note it seems like the toxins found in plants, a reason for why Ray Peat avoids vegetables, is to the contrary mentioned as a good thing in this fascinating article on antioxidants (it was mentioned on Paleohacks on the subject of supplement abuse):

http://gettingstronger.org/2011/03/the-case-against-antioxidants/

there is logic behind the paleo diet principal, what is his logic? why vegetables no, but fruit yes?
sure people might get results following his advice, people get "results" eating 50 bananas a day. Most of it seems good though, try it if you want..

Peat is not totally anti veggie.. He promotes intake of carrots before starchy meals and promotes some root/tuber veggies..

3 questions:

(1) Is he advocating fruit juice as in commercial fruit juice or home-made, hand-squeezed fuit juice devoid of HFCS?

(2) Is he advocating sugar as in granulated white sugar or sugar that's naturally in fruit and vegetables (endogenous sugar)?

(3) How old is Mr. Peat? Judging by his voice, he is quite up there. If he is, he could cite himself as the best example of his own diet for promoting longevity.

I do agree with his general opinion that PUFA is harmful, even Omega 3 FAs. But his other opinions are hard to square with current research.

Other than high blood sugar possibly causing myopia (he wears glasses), could work for some people.

I've been listening to one of the followers of Ray Peat's diet... and I must agree that his ideas just don't "ring true." Based on common sense, leading edge nutrition doctors, and intuition and gut instinct they don't make sense. I tried listening to them and tried thinking outside of the box but I couldn't believe it.

I do believe some vegetables are hard to digest (Kale) and require juicing, etc. and I do believe pasture-organic dairy is good when raw an un-altered but to live on only protein and dairy and carrots just doesn't do it for me. It goes against every grain of knowledge.

Your synopsis of Peat is so cryptic and oversimplified any response is difficult. The term 'peleohacks' seems geared to excite readers to criticize first and think later, and calling Peat a charlatan only wastes intelligent readers time, whether it provides a cathartic outlet for others or not. I'll take on one critical arena -

Peat's point about vegetables if vital and helpful. Many families today are so brainwashed by popular and chaotic claims for foods in the mass media that they forget ordinary caution and common sense. I've seen families here in the bay area of California who think they are advanced and enlightened, while their children are so thin it's frightening. And vegetables are always, not sometimes but always, high up on their list of things to eat all the time, morning noon and night. Under those circumstance you can the signs of poisoning related to the natural feature of vegetables to defend themselves with bio toxins. Their children are not just thin, but gaunt, also tired, listless, poorly coordinated, and withdrawn. These are more than signs of starvation - which is probably a factor in their plight - these are signs of downright poisoning, and it doesn't take long to find out what the culprit it - mountains of root and other vegetables that are often eaten uncooked, and a marked absence of milk, meat, other proteins and fats. Humans need fats in moderate, not small amounts, and a lack of fats encourages too rapid and incomplete digestion that is a large factor in making vegetables a problem.

The healthiest, most sustainable and most economical diet in the world is a vegan diet.

Ray Peat is a charlatan. He avoids rigorous peer review and seems to have recruited a team of white, upper middle-class women (with too much time on their hands and imaginary intolerances) to endlessly recite his groundless 'research' [SIC]. Most of which seem to be offering paid-for consultancy services - shock, horror.
