EXERCISING ON AN EMPTY STOMACH: DON’T DO IT

If I perform cardiovascular exercise on an empty stomach–will doing so result in greater fat loss?

This is another popular myth that needs to be discussed! Performing cardiovascular exercise on an empty stomach for the purpose of burning more fat, is in fact, an empty promise!

The truth: It is VERY important to eat a small, approximately 100-calorie snack, about an hour before exercising so your body has enough fuel to power through your workout! A combination of carbohydrate, protein and fat is acceptable. The issue here is really one of “carbohydrate burning” versus “fat burning.” Experts across the world, while acknowledging that intensity of effort (how hard you workout) is the determining factor with regard to how much fat or carbohydrate will be burned per single calorie—agree that the overlying factor that contributes to greatest weight or fat loss, is total calories used or burned.

The take away message here is…. from a fat loss standpoint it is not important to differentiate what types of energy sources–fat or carbohydrate—are being burned (utilized). Period.
