Rational Criticism

When did Peat ever put fat in equivalent weight as carbs in a putative "Peat Diet?" I say putative because Peat vehemently denies there is such a thing as a Ray Peat diet in an email exchange I had with him. Yet it can't be helped when the tendency of most people is to categorize in pigeon boxes than to deal with the nuance of nutrition customized to the situational context of each individual.

Ray is pro carbs, but not as pro fats as he is pro carbs. He is pro sat fats and monounsaturated fats, but all manners of PUFAs are a big no no for him. He isn't very fond of starch , especially from grains, as he sees grains as coming from seeds, and seeds contain allergens or anti-nutrients that are the grain's way of protecting itself from being eaten too readily, as a means of survival by grain plants.

Still on the subject of starch, he has no objection on potatoes and on around tubers. In fact, he likes potatoes because it contains keto acids, which can be used by the body to convert keto acids with amino acids present in the body to form protein.

For this reason, he has no objection to simple sugar such as sucrose, and even likes Mexican cola for the cane sugar it contains. He also likes fruits for the half glucose and half fructose it contains, as they aid each other in getting absorbed and metabolized by the body.

He certainly prefers the body to burn more sugar than fats, as burning too much fats would leave little room for sugar to be burned mitochondrially, which is more efficient in terms of energy production and which also produces carbon dioxide, which the body needs, such as in maximizing tissue oxygenation (allowing blood to release oxygen to the tissues), as well as in maintaining a stable pH (aka acid base balance) to help the body operate without a lot of stress, which contributes to health and longevity.

His views on protein is dependent on the context of the stage of development of the person. A growing person needs plenty of animal protein that is rich in methionine and cysteine (as well as other essential proteins), as they are much needed for growth. But when a person has matured, and is no longer growing structure, he needs methionine, cysteine, and tryptophan much less, as these amino acids in large quantities, are often involved in creating more stress and aging. Instead, he favors glycine, which is found in gelatin or collagen, which helps preserve the structure in a mature person. He also believes less protein is needed in nutrition for mature individuals, though more is recommended for growth for children and adolescents and growing adults.
