How long before I can expect to see results on the Zone Diet?

Within two to three days you should see a noticeable reduction in your carbohydrate cravings with increased mental focus. Within five days you will notice a significant decrease in hunger throughout the day coupled with greater physical performance and less fatigue as the day wears on. Keep in mind that this is a fat loss program and don't expect rapid weight loss. The maximum fat loss you can expect, no matter how strictly you follow the program or how much you exercise, is one to one and a half pounds of fat per week. It is simply impossible to reduce excess body fat any faster on any dietary program. Within two weeks, you will notice that your clothes are fitting much better. Although you will not experience dramatic weight loss, judge your success by the fit of your clothes and changes in body composition.
