The thing with carbohydrates is that ,complex or simple, once they are in the blood, sooner for the simple et later for the complex, they have a very simple fat(e): if one's very active, physical, they are burnt as fuel for the muscles. If one does nothing physical afterward, they are stocked as fat.If one hasjust done some difficult exercice, they are stocked as glycogen in the muscle in the first place because the glycogen stocks are depleted. So for dinner,when bedtimei s coming the one who wants to lose weight should avoid them and eat plenty of green veggies instead unless he just has done aerobic sport.
