What is a "negative calories" diet?

Answer by  mem4dr (1378)

A negative calories diet usually means that you only eat food (like celery) that takes more calories to digest than it contains. Very low calorie/negative calorie diets are dangerous.

The negative calorie diet is when you take in less calories than your body needs to survive, either by excessive exercising or extreme dieting. This is very harmful to your body becuase your body needs positive calories for fuel and to function.

It means that you burn more calories than you consume. It can hurt you. Pro athletes sometimes do it supervised a few days before competitions.
