Have you ever noticed that you eat while you watch TV, drive, work, talk on the telephone? That sometimes you just eat, mindlessly? Just shoveling food in with no real thought about whether it tastes good, feels good, IS good?
Are you one of the many of us? The people who eat too fast, too thoughtlessly, too unhealthily? Are you so busy filling the next forkful that you don't even notice the wonderful bite of food already in your mouth?
Since your brain can only really focus on one thing at a time, when you eat while doing something else you far too often miss the subtle signs of fullness that tell you to STOP! At least not until you feel uncomfortable or until you run out of food.
