The Theory Behind the "Negative Calorie Effect"
All foods have a nutrient (carbohydrate, fat, protein), caloric (calories) and vitamin & mineral content. Vitamins stimulate living tissues to produce enzymes that breakdown the caloric nutrients of that food.
Foods with negative calorie contain sufficient vitamins & minerals that produce enzymes in quantities sufficient to break down not only its own calories, but additional calories present in digestion as well. This is called "negative calorie effect".
