can someone explain how the GI diet works????

Answer 1

By eating meals that have a low GI you will feel less hungry. This means that rather then controlling your cravings for food by will-power alone your are controlling them by satisfying your body. On the GI diet your desire to snack or over eat should be greatly reduced, therefore by eating fewer calories you can control your weight.
