Some researchers have considered the possibility that a food might be negative-calorie due to the calories exerted while chewing. The following are some of these allegedly negative-calorie foods: In most cases, these foods also provide valuable nutrients at no caloric cost. These foods use more calories for digestion than they provide to the body. ![]() Negative calorie foods are the exception. High-protein foods require a lot more energy to digest, so negative calorie foods are always low in protein.
