Eating until you are full can be harmful for your health. If your stomach has to process an excess amount of food,all that will happen to it is that the excess food will be simply converted into fat and stored somewhere on your body, resulting in unwanted weight gain. You should always make it a point to stop eating just before you reach the point of feeling full. Your stomach should still feel light, but you should no longer have any feelings of hunger in your stomach. You should be willing to get up and walk away from the food on your table, even if you have leftovers.  Go to Ab Circle Pro for more info and details.
