-Dairy, meat and fruit are the core of his diet.
-He believes in consuming lots of gelatin and limiting muscle meats.
-States protein must be balanced with sugar, according to him protein alone lowers blood sugar so it must be eaten with fruit.
-He believes PUFA's are not essential, and most of our fat should be saturated from cream, butter, tallow and coconut oil.
-He believes vegetables are poisonous.
-Believes in the high consumption of fruit and fruit juices and I think he favors fructose over starches.
What is your opinion on his ideas, particularly his stance on fruit? Are they sound and based on science or are they pure speculation? His ideas do seem a bit out there, but I have read of many people having success on a diet similar to one that Ray Peat recommends?
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 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 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 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.
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):
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..
(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.
