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.
