Negative Calorie Food
Negative calorie foods are foods, which use more calories to digest than the calories the foods actually contain!
Calories from these foods are much harder for the body to breakdown and process. In other words, the body has to work harder in order to extract calories from these foods. This gives these foods a tremendous natural fat-burning advantage.
