Sigh.

Yes, it is well supported by the research, did you actually read it?

I actually had a nice phone call with the lab that produced this paper. You can explain a percentage of weight changes by calorie intake, but the factors that explain glucose curves (and thus uptake of calories) require far more data (like genetics, etc).

Your call with the lab is an attempt to appeal to authority. Also, thanks for the "sigh".

I read your link. It's about blood glucose. Not about weight. The crux of your argument is that blood glucose response equals uptake of calories, which is not supported by your link, and which is not true. If it were, you could eat 5000 calories of fat in a day, have no blood glucose response, thus not get fat.

Are you really trying to claim that the outlier participants of whom the blood glucose plots are shown in your link are unable to use any of the calories in bananas/cookies, because they had no blood glucose response?

Apologies, but the "sigh" was for the "not supported by the study, and also nonsense" comment. I find it annoying when supported arguments are dismissed out of hand without compelling counter evidence. It sounds childish, like "no you are wrong, because naaaah". If that wasn't what you meant, please be more thoughtful.

Regardless, we can talk about metabolic pathways. If you consume carbohydrates, they eventually get dumped into your bloodstream as glucose (minus fructose, which is special). The level of glucose then absorbed into fat cells is regulated by insulin, and insulin production (while more complicated) is determined by the level of glucose in the blood.
