Do you have a problem if not eating is based on controlling your weight and self discipline and having the feeling that you fail every time you eat something knowing you can stop whenever you want?

Possibly. Not eating is a poor way to lose or to control your weight. Exercise and proper nutrition are far better ways of dealing with weight issues, and improve self-esteem, outlook, and overall health. If you feel that you must not eat, you should see a counselor, as this can become a life-threatening problem. Simply walking briskly several miles a day can do amazing things for your weight, and will make you feel better, too. Eat slowly, so that your body can tell you when it is full. It can take as long as 20 minutes for your stomach to let your brain know that you are full. Take smaller portions, don't go back for seconds, and don't eat anything for the two or three hours before you go to bed. Go to bed hungry, instead of stuffed, eat a good breakfast, and a good lunch, and a small dinner. If you can, try to go swimming a couple of times a week, or ride a bicycle several miles, or split wood, or rake leaves, shovel snow, dig holes or trenches, stack wood, whatever you can to be active. Being outside, away from the television, is one of the most critical parts of weight control.
