What is the Negative Calorie Diet
The Negative Calorie Diet is based on the theory that some foods use more calories to digest than are contained in the foods and that this can be used to produce weight loss.
The idea is that some foods take more calories for the body to process and digest than are contained in the foods themselves.
When a person eats a piece of food the first thing that happens is chewing and this action consumes energy. Foods that are higher in stringy fibers, such as celery, generally require more chewing, and hence more energy expenditure, than other foods such as cake which do not require as much chewing. After chewing, the food is moved down the esophagus and into the stomach, where it begins to be broken down as it mixes with stomach acid. Then it is moved into the small intestine where it is liquefied and absorption into the body begins. Then the mass moves into the large intestine where fluids are absorbed and then the residual mass is excreted.
The Negative Calorie Diet believes that this entire process of digestion uses many calories, and so by eating foods that are low in calories, and take longer to digest, the body will actually be using more calories than are taken by processing the foods. The diet claims that these extra calories required for digestion are taken from fat stores in the body, and that the more of these negative calorie foods the dieter eats, the more weight will be lost.
The Negative Calorie diet gives, as an example, the net calorie consumption from eating broccoli. It says that if you eat a serving of 100 grams of broccoli, which contains 25 calories, it will take the body 80 calories worth of energy to digest it. This results in a negative net calorie use of 55 calories which are supposed to be taken from fat stores on the body. As a counter example the diet says that if a dieter eats a piece of cake that contains 400 calories, it will take the
body 150 calories to digest it, and the net 250 calories taken into the body will be stored as fat.
