If you want to get in more carbs just for the calories go for the sugars not the starchs. It the fiber that makes you feel full and slows digestion. Fresh fruit juices would be your healthiest choice but drink chocolate milk, gatorade, even soda. The liquids will go down easier without filling you up. Dried fruits are also very calorically dense and not too filling, tasty as well.[/quote]
Starches can be as fast or faster then sugars Look at Maltodextrin, white potatoes, white rice, white bread. all primarily starch based but FAST as shit.
Try and get in high impact quickly digested food like those and fats.
