Negative calories

From Wikipedia, the free encyclopedia

Negative calories are Calories which burn more energy during the digestive process than they themselves physically comprise. Negative calorie discussion is found in both the dieting and eating disorders communities.

The theory of negative calories, which is not formally supported by physicians or other scientists, states that the calories eaten in certain foods, especially those such as vegetables and fruits, will be expended in physiological excess in digestion. This means that not only will the calories from the food itself be burned, but that extra calories are required by the body, from other fuel or bodily sources, to fully complete digestion.

The existence of negative calories is widely debated, and its scientific validity has yet to be determined.
