The theory of zero calorie foods is that the body will burn more calories metabolizing and cooking the food than the calories the food contains.
This is a process called thermogenesis, and it’s how your body heats itself up.
So it doesn’t mean that the food literally contains ZERO calories. It does contain some calories, but the body burns off more calories eating and digesting the food than the food itself contains.
So make sure you add more of these foods to your diet any chance you get! They will keep you away from calories and still fill you up.
The zero calorie foods for weight loss were selected based on two criteria:
- The first was that they must be full of nutrients like vitamins and antioxidants for your health.
- The second is that they must be under 100 calories per 1 cup serving
Apples are one of the healthiest fruits on the planet, containing antioxidants, vitamins, minerals, and even pectin (which has been shown to reduce hunger).
Eating an apple can be a great snack between lunch and dinner because it will keep the body full while providing a small energy boost.

Celery has long been touted as a zero calorie food.
It is a good source of vitamin K and water, so it can be filling. However, there is an obvious problem with this food: It has virtually no taste. People tend to add peanut butter or cream fillings to this snack, which runs up the calorie count.
