A negative calorie food is one which burns more calories during digestion than your body gets from the food itself. These foods are supposedly helpful for weight loss, since you are actually burning calories the more you eat them.
What about bananas? Do bananas contain negative calories?
No, they do not.
They average banana contains quite a lot of calories, with approximately 108 calories per banana. This is far more than it would take to digest that banana!
If you’re looking to lose weight, it’s probably best to limit the amount of bananas in your diet, as they are high in both calories and carbohydrates.
