Negative Calorie Foods
With negative calorie diet and several versions of this diet, dieters are to eat and drink food products that are nutritous but are said to have a negative caloric effect; i.e., they provide fewer food calories than the calories needed to digest them.

Some criticize that such dieters use the concept of negative calories to justify eating unlimited quantities of such foods, and that doing so is not healthy. In all cases, when in doubt, ask your physician.
