I have stuck to it without cravings or other problems for several years now. Here is some background on the Zone diet. I'll be as brief as possible here, but since this diet did make a major improvement in my condition, I feel I do need to explain how it works. The Zone diet is a diet that is very balanced. It also recommends the avoidance of high glycemic foods.
Every carbohydrate has a glycemic index .
This is a measurement of how quickly a person's blood glucose rises after eating the food. A food with a high glycemic index such as sugar will send a person's blood glucose level up quickly. The body will then respond by producing high levels of insulin. Insulin is a hormone that promotes the conversion of blood glucose into fat. Diabetics must avoid high glycemic foods since they are unable to produce the necessary insulin to counteract the blood glucose.
