NEGATIVE CALORIES

Negative calorie diet: The Negative calorie diet is a weight loss concept based upon the premise that consumption of foods with a “negative caloric effect” (meaning that the calories burned by chewing, digesting, and eliminating the food are greater than those contained in the food itself) will lead to rapid weight loss of up to two pounds per day.
