The Zone diet is based on the concept that hormones are kept in areas that are carefully balanced. By controlling the balance of these hormones, you increase fat loss and decrease the likelihood of developing diabetes and heart disease, in addition to improving your physical and mental endurance.

This diet program has been designed to balance your intake of proteins and carbohydrates: one part protein for 4 parts of carbohydrate. This suggests a moderate intake of carbohydrates, proteins and fats in order to control insulin.

The majority of carbohydrates from the diet zone comes from fruits and vegetables but it also includes a limited amount of bread, rice, potatoes and grains. Most of the fat intake should come from monounsaturated fats, like olive oil and other oils that are good for your heart.

The other component of the Zone Diet is the oil that comes from fish supplies omega 3 fatty acid which is an important component for maintaining healthy cells.
Numerous studies over the past five years have confirmed the importance of joining the fish and omega 3 fatty acids in the diet of everyone.

The Zone diet combines small servings of protein low in fat, vegetables rich in "good" fats, fiber, and fresh fruit. The plan also suggests eating protein at every meal or snack and suggested to take at least 3 meals and 2 snacks per day.
