A zone diet is important not only for weight loss but also for health. It helps prevent cardiovascular disease or diabetes. In addition to weight loss, the main goal is to maintain blood insulin and glucose levels by consuming low-calorie and low-carbohydrate foods. To achieve the ideal balance, it is recommended to take 40% calories from carbohydrates, 30% from proteins and 30% from fats. You should eat at regular intervals with a maximum of 5 hours between meals, based on 3 meals and 2 lead meals per day. The diet focuses on the intake of good fats (unsaturated) and sugars (low glycemic index). All food needs to be weighed; you can't eat as much as you want.
