The only truly zero calorie substance is water, but there are many foods that are listed as negative calorie foods. This is because the process of digesting your food uses energy and therefore burns calories. Indeed, while your body is digesting your food, it is channeling most of your energy in that direction. Negative calorie foods are those that do contain calories but in such small amounts that your body needs to use more calories to digest them than they contain. Hence, including a significant percentage of negative calorie foods in your everyday diet will inevitably provide a big boost for your fat loss efforts and nutrition health plan. Some negative calorie foods:
