the zone diet plan
The Zone Diet plan consists of balancing your diet and ensuring 40% of your daily caloric intake is in the form of carbohydrate, 30% protein, and 30% fat.
The reasoning is that when you eat food, it is broken down into it's basic components, glucose, amino acids, and fatty acids, and enters you bloodstream. The Zone Diet argues that food should be though of as a drug that has a powerful effect on the body.
Therefore every meal and snack needs to have the right levels of nutrients (protein, carbohydrate and fat) to produce an appropriate hormonal response
A key point of the diet plan is not to focus on calories but the ratio of protein to carbohydrate. You need to aim for a ratio of 0.75 protein to carbohydrate. i.e. 1 gram of carb to 0.75 grams of protein.However, the amount of protein required by each of us is different. It is based on your physical activity, weight and body fat.
