Carbohydrates and protein provide 4 calories of energy per gram while fat yields 9 calories per gram. Carbohydrates are broken down into glucose and absorbed into the bloodstream. Fat is a major source of stored energy and is held as a reserve in the body until we need it. Fat is the preferred source of energy for the heart.
