> if everyone who was obese in this country all of a sudden started eating a diet that was macronutriently ideal and consumed at the perfect times, but maintained the same number of calories, there would be no difference in the prevalence of obesity. I think the science really confidently supports that position, and I'd be happy to look at anything you think denies it.

Again, no. You are tautologically restating CICO. We have no evidence of this being true. You are implicitly assuming that CO will be constant and would be independent of CI... We do not know that to be true.

> I am very familiar with Dr Fung's work and don't think that any of it makes the case you are trying to make. All of his work provides proof for what I've been saying over and over in this thread: IF and Keto can be great ways to create compliance to a diet, but there is no evidence, including the work of Dr Fung, that shows these diets behaving differently from simple calorie control outside of the compliance aspect.

I seem to recall a bunch of animal models where compliance was controlled for and still showed a strong correlation between insulin and set weight.
