Do negative calorie diets work?
The only problem with the negative calorie diet is that no negative calorie foods exist. The foods mistakenly believed to be negative in calories are low-calorie high-fiber foods such as fruits, berries and non-starchy vegetables. Though your body does not burn more calories to digest the foods than you take in with the foods, they still help you lose weight as fiber fills you up and you avoid overeating.
