Here is a list of negative calorie foods. No that doesn't mean the foods have negative calories ;) I wish lol. What it means is that when you eat these foods raw or in some cases slightly cooked with nothing on them your body burns more calories digesting and processing them than what is in the actual food itself. For a healthy weight loss and a little boost add some of these foods to your diet each day. Most are full of nutrients and won't weigh you down.
