How the Zone Diet works for weight loss
The zone diet is based on the theory that a high-protein, low-carbohydrate diet can change a person's hormonal balance between fat-storing insulin and glucagon and send them into a state known as the ‘zone' where they will lose weight and not be hungry. According to the zone diet, if a person consumes the ideal ratio of carbohydrates, proteins, and fats (40-30-30 respectively) they can control their insulin production and burn excess body fat. While on the zone diet, it is recommended that people eat low-fat protein, carbohydrates rich in fiber, and monounsaturated fats. While on the zone diet, a person should make sure they get enough omega-3 fish oils from either their diet or a supplement in order to maintain good health.
Advantages of the Zone Diet for weight loss
On the zone diet, calories do not have to be counted. However, because many of the recommended foods on the zone diet are low in fat, a person may lose weight while being able to eat high protein foods such as steak. There are meal plans available to make meal planning easier for people on the zone diet.
The Zone diet is based on some physiologic principles and makes sense. The diet does have scientific studies that were not funded by Zone Diet.
Disadvantages of the Zone Diet for weight loss
It may be difficult to make each meal follow the 40-30-30 (C:P:F) ratio while on the zone diet. The zone diet is low in carbohydrates which can decrease a person's energy levels. The zone diet is also low in fiber and some vitamins and minerals since starches such as pasta, potatoes, and bread are severely restricted.
