Nutritionist Debunks the Idea of ‘Negative Calories’

A calorie is a unit of energy, usually expressed as kilocalories (kcal) for the energy content in food. The theory behind negative-calorie foods is that some foods have lower calorie (energy) content than the amount of energy it takes to digest and absorb the food into the body.
