"Hi Ray, I'm wondering about fruit and its avenues of metabolism. Regarding this study, The effect of two energy-restricted diets, a low-fructose diet versus a moderate natural fructose diet, on weight loss and metabolic syndrome param... - PubMed - NCBI
A commenter said,"
That study does''t eliminate fructose as one of Kurt Harris‚ neolithic agents of disease. Nor does it even mean much in the real world.
Note that both groups were on a calorie restricted diet. The negative effects of fructose consumption are due to the limited avenues available for its metabolic disposal via the liver (glycogen or triglycerides), the limited capacity of those avenues, and its availability in drinkable form (sodas, fruit juices, smoothies).
Putting people on a calorie restricted diet ˆ and one that also doesn‚t include liquids (their most common delivery form, by far) ˆ purposely eliminates the real-world consumption and metabolic scenario. The danger of fructose is that its sweet taste tempts us to consume giant boluses of it, which overwhelm in the short term the ability of our liver to process it (= glycation = heart disease). In the longer term they overwhelm the ability of our liver to store it (= NAFLD, T2D, etc.) None of this happens on a calorie-restricted diet or under conditions of daily intense exercise that continually depletes glycogen reserves. Thus Grok and the fruitarians.
I don't enjoy being the wet blanket here, but this study still tells us nothing about the effects of fruit-sourced fructose eaten as part of a non-restricted diet ˆ in other words, the real-world case.
Seriously: I know it's fun to question authority, maaaaaan, but please: let's all think a bit about the metabolic pathways involved before gleefully setting fire to everything that got us where we are."
I'm very curious what you think about it."

"I keep thinking about doing a newsletter about fructose, but I think the ideology behind the hatred of fructose is the real issue. The typical internet libertarian ideology thinks the killer ape doctrine of Konrad Lorenz, Robert Ardrey, and Desmond Morris is the essence of anthropology. For most of these people, hunter-gatherers were just hunters who found some seeds occasionally."
Ray Peat Email Advice Depository
I find it interesting that Ray Peat was willing to make that argument. It seems as though Ray Peat believes that certain political ideas seem to reinforce nutrition and health trends. But I think he is right. Libertarians definitely hold onto certain ideas that makes it harder for people to see reality. Or in this case, health and nutrition.
It's also interesting that Ray Peat incorporates Konrad Lorenz with the libertarians. Even though that is a radical statement. There are certain members on this forum who have openly promote libertarianism while promoting ideas from Konrad Lorenz like genetic theory of intelligence or the greed and violence theory of human nature. Which ties nicely into the killer ape ideology. And that with the hatred of Fructose.
I think Ray Peat is more aware of political trends then what we give him credit for. And that we are closer to understanding his political ideas in total. One thing is for sure, he isn't big on libertarianism.
