The first thing many of us consider while losing or gaining weight is calorie intake. The energy stored in food or body tissues is measured as calories. So whether it is for weight loss or maintaining a healthy body, it is recommended to focus on eating fewer calories. Or you can use physical activity to burn more of your body’s stored calories. But there are “negative calorie foods” available that are becoming popular in weight loss diets. This means that the negative calorie foods consumption makes your body lose calories without adding any.

This article tells us everything we need to know about negative calorie foods and how they might aid in weight loss.

What are Negative Calorie Foods?

The three primary forms of calories that dole out energy to our body are carbs, proteins and fats from the food that provides our body with nutrients. So when you have to digest and process any food you eat, your body will expend energy. And the amount of energy your body requires depends on the type of food.

A Negative-calorie food is a food that supposedly requires calories to process, digest and eat rather than giving any calories to your body.
