Potatofree, I think that this is one of those issues where some hormones are pro-burn and some are pro-fat accum. As for John Pruns, I'm not sure what I think about his ideas on diet affecting fat storage either, so I'm guessing that in an interview situation, he made A LOT OF OPINION comments that were not based on his research or anyone else's, but were just conversational (re: the comment i posted that he said dietary fat makes for stored fat better than sugar, as well as that eating fat makes people more hungry than sugar). I'm taking his opinions with a BIG grain of salt and that's why I went directly to his published research where you aren't allowed to make those kinds of reaching assumptions without data to back them up.
