For those of you who are unfamiliar with the concept of negative calories and negative calorie foods, here’s the short version:
The theory is that a negative calorie food is any food that requires more energy to digest than the energy (calories) actually contained in the food. The idea here is that by eating these foods, you can burn more calories than you consume and lose weight more rapidly and efficiently.
Whether this is true or not is not scientifically proven. But a diet that consists of these fruits and vegetables will help you lose weight. Just remember moderation is the key.
