The Negative Calorie Food is a food that creates negative calorie effects, which helps to lose weight.

The Negative Calorie Foods are foods that consume more calories to digest than the calories food actually contains. The Negative Calorie Foods produce fewer food calories than the calories needed to digest them.
The calories provided by these foods are much harder for the body to use. In simple words, the body has to work hard in order to extract calories from these foods. Even though foods may contain equal amount of calories, much less of these calories can possibly turn into fat in fat burning foods (negative calorie foods) as fewer calories are actually available to the body. This gives these foods a tremendous natural fat-burning advantage.

The Negative Calorie Foods have maximum benefits when eaten without any empty calorie foods (junk foods). There are several vegetables and fruits that have negative calorie effect. The foods highly generous in the negative calorie effect include Asparagus, Beets, Carrot, Zucchini, Papaya, Strawberry, Raspberry, etc.

The Negative Calorie vegetables include Asparagus, Beet Root, Broccoli, Cabbage, Carrot, Cauliflower, Celery Chicory, Hot Chili, Cucumber, Garden cress, Garlic, Green Beans, Lettuce, Onion, Radish, Spinach, Turnip, and Zucchini etc.

The Negative Calorie Fruits include Apple, Blueberries, Cantaloupe, Cranberry, Grapefruit Honeydew, Lemon/Lime, Mango, Orange, Papaya, Peach Pineapple, Raspberry, Strawberry, Tomato, Tangerine, Turnip, Watermelon etc.

Working:

The normal foods have a nutrient (carbohydrate, fat, and protein), caloric (calories) and vitamin & mineral content. Vitamins stimulate living tissues to produce enzymes that breakdown the caloric nutrients of that food.

The weight losing process requires to burn more calories than one consumes. The Negative Calorie diet works on the concept that certain negative calorie foods contain a surplus of vitamins and minerals which can speed up enzyme production in quantities sufficient to break down not only its own calories, but possible additional calories present in the digestion system. This is the wonderful secret of The Negative Calorie Foods.

Opinion:

The Negative Calorie Food theory is controversial because it is not scientifically well accepted. There is no clear evidence that any foods are truly negative calorie. The critics of the Negative Calorie food argue that no foods possess ‘negative’ calories and one cannot eat in one’s own way to weight loss. They also purport that by following the Negative Calorie food one is potentially offsetting one’s positive calorie energy reserves, cancelling out the effectiveness of weight training. This criticism argues that one needs calories to create energy both for exercise and for recovering from exercise.

On the contrary, the advocates of the Negative Calorie Diet concede it is true that there is no such food, which contain ‘negative calories’. However, they do argue that the by ingesting certain foods certainly increases the metabolic processes that can result in weight loss.
