There are certain types of food which when consumed, actually burn more fat than the calorific value of the food itself. These kinds of foods are also known as negative calorie foods. They are classified into three different groups such as the citrus group ? consisting of lemons, limes, tangerines, grapefruit, oranges, kiwi fruit etc, the cellulose rich fruits and vegetables group consisting of cabbage, asparagus, beetroot, broccoli, blueberries, apple, watermelon etc and the dairy group of foods including non fat milk, white cheese and low fat yogurt. As far as dairy products are concerned, they have clinically proved it that calcium rich dairy foods help in weight loss by increasing the breakdown of fat in fat cells. Hence, non-fatty dairy products should be included in the diet towards weight loss. When these foods are combined with mild exercise, tremendous results are achieved.

Cinnamon is the oldest spice which was once considered to be more precious than gold and were used by the early Egyptians for medicinal purposes and for flavor in foods. It was accidentally found that foods containing cinnamon helped in reducing the blood sugar level in the body. If cinnamon is added to the diet in any of the forms such as herbal tonic, or as a capsule or by sprinkling over foods, it tends to reduce weight.

Foods which are metabolism friendly and the carbohydrates with lower or moderate glycemic indexes help in weight loss. Normally foods which are rich in protein are low in carbohydrates and in turn are with low glycemic index. Such foods are eggs, turkey, fish, red meat, ostrich, chicken etc. To minimize fat, lean cuts of meat, or chicken without skin can be eaten. Soy products like tofu, soymilk, soy powder etc are very good for weight reduction.

Raw vegetables and green leafy vegetables are lower in glycemic index, carbohydrates and fat and they are very much higher in minerals, vitamins, anti oxidants and fiber than when they are cooked. Fruits with high glycemic index need to be avoided and those with lower glycemic index can be consumed.
