Hi.
According to Dr. Karen Rosewater, binge eating affects your metabolism, which controls the efficient use and burning of the calories we ingest. Binge eating confuses the metabolism into thinking that the "dry times"--those times in which you're eating very little--is starvation. Therefore, the body holds on to more of what you eat.
So, while the goal of binge eating may be to maintain control over your weight, binging can often make people gain even more weight and feel even more out of control and powerless in their lives. It's a vicious circle.
Binging can also be hard on various systems of the body, including your liver and bowels, so try to get some help to stop this pattern.
Many people are helped by therapy in which they learn to recognize the feelings associated with their binges, and change their behaviors in response to those feelings. In some cases, anti-depressants have been helpful in calming the urge to binge. Talk to your school counselor or your parents about seeking help, and get an evaluation by a trained mental health care provider.
Take care.
