There are a number of diet plans around these days promoting these so called "negative calorie" foods.
But it must be remembered that all food contains calories.
But the diet plans on the term "negative calorie" foods are refering to how your body processes these foods.
They claim that these "Negative Calorie Foods" take up more caloric energy to digest then the calories that are in the food.
The "negative calorie" foods allowed in this diet are mainly vegetables and fruits.
The theory of negative calories, is not formally supported by physicians or other scientists.
