It is a well-known criteria that when calorie consumed is < calorie output, people tend to lose weight. It is important to understand that all calories are not the same. Negative calorie foods do help in losing weight as they are not only low in calories but they also help in burning more calories during digestion. Let’s understand what are negative calories and why are they so important and popular to lose weight.

Negative calorie foods are those that are nutritious and low in calories. By consuming these foods, the body ends up burning more calories in digesting them than what they inherently contain. Generally, foods with high fibre and water content are low in calories and their digestion requires more energy.

These foods boost your metabolism as they are rich in fibre, which takes a longer time to burn and thus keeps your metabolism revved up. Foods that can act as negative calories in your body include:
