Don't Eat Fast-Digesting Carbohydrates

Fast carbs spike insulin, which halts fat-burning and boosts fat storage, particularly on top of your abs. Carbs to avoid are white bread, white potatoes, regular sodas, sports drinks, table sugar, etc. Instead, choose whole-wheat, rye or sourdough breads, oatmeal, sweet potatoes, fruits, vegetables, quinoa, legumes and brown rice. One exception here: You can eat fast-digesting carbs right after workouts when they’ll be put to work boosting muscle recovery and growth.
