If you're eating excess carbohydrate (defined as when your glycogen stores are full) then that energy is converted to body fat in a process called de novo lipogensis. Insulin plays a major part in this process.
If you are doing regular *high intensity* weight training then you will be depleting glycogen stores in the muscle and can afford to eat more carbs without storing body fat.
If you're not weight training hard, and eating lots of carbs, your waistline will be expanding.
