Negative calorie foods are foods high in dietary fiber, vitamins, and minerals that make you expend more calories digesting them, more than what they offer.

For example, a stalk of celery contains about 6 calories. But due to its high dietary fiber content, your body will burn more than 6 calories to process the celery. So, basically, you will burn calories without even hitting the gym.

Sounds amazing, right? Before I unravel the negative calorie foods list, let me address a popular question – do negative calorie foods exist?

No, these are not foods without calories. Neither do they contain calories in the negatives. To enjoy the benefits of these foods, you must first know how they work. Take a look.

Low In Calories – Whole food sources that are low in calories but loaded with nutrients are great for weight loss. But you should not only look at the calories. For example, avocados are high in calories, but they are also nutritious. On the other hand, diet soda has zero calories, but it contains other additives that make it harmful.

Calories Burnt While Chewing – Negative calorie foods are loaded with dietary fiber and take longer to chew – this helps you burn calories (like how you burn calories while chewing gum (3)).

Calories Burnt While Digestion – Foods rich in dietary fiber are tough to break down. So, the stomach has to work extra hard and burn more calories to ensure the food gets absorbed easily.

When we talk about “negative calorie” foods, we strictly mean foods that are low in calories, nutritious, and require the body to burn more calories in processing them for energy. Now, let’s take a look at such foods.
