Eating a breakfast made with "slow-release" carbohydrates, such as oatmeal or bran cereal, three hours before you exercise may help you burn more fat, suggests a recent study in the Journal of Nutrition. Here's why: in the study, eating "slow-release" carbohydrates didn't spike blood sugar as high as eating refined carbohydrates, such as white toast. In turn, insulin levels didn't spike as high and because insulin plays a role in signaling your body to store fat, having lower levels may help you burn fat. Want options beyond oatmeal? Here are 10 breakfast recipes to help you fight fat.
