digestion itself does not burn fat. it is used in the absorption of fat, not burning it. same thing as with protein. protein is absorbed in the body, in turn, could possibly lead to weight loss or weight gain if not utilized properly. well, i'm not an expert too. i'm taking up nursing and i knew all of these stuffs from our nutrition subject from a professor who is a nutritionist. in that sense, i can't disagree with her coz that's her field and she's an expert.
interesting...we got a nice discussion here.. if you guys are confused. crashburn is right...do some research and leave it to the experts..
