When making your own diet to lose weight, it is important to include foods that are the lowest in calories. So, what can be lower than negative-calorie food? Let us learn more about such food and decide which products are the best in this category.
What are Negative-Calorie Foods?
Negative-calorie foods are products that require more energy to be digested than they provide. This means your body should spend more calories to digest the product than there are in its content.
Even though there is no actual scientific evidence on any food being negative-calorie, it does help lose weight a lot.
You cannot certainly put a product in the list of negative-calorie foods, as the amount of energy, needed to digest it, depends on your weight, health and genetics. However, if it is in the list, then it is very healthy and really low in calories. It does not matter if you have lost 5 calories by eating anything or gained them, as long as you have not eaten much, but received the necessary amount of nutrients.
