A negative-calorie food would be a food that required more food energy to be digested than it provided. That is, itsthermic effect – the caloric "cost" of digesting the food – would be greater than its food energy content. The thermic effect is scientifically called specific dynamic action. While this concept is popular in dieting guides, there is no scientific evidence supporting the idea that any food is a negative-calorie food.Some soft drinks are erroneously advertised as having "negative calories". The only truly negative-calorie beverage is ice water, which has no calories but requires the body to expend a very small amount of energy to raise the liquid to body temperature.
