I would like to know about the strategies to overcome binge eating. Please explain.

Counseling. Counseling and knowing how to normalize eating habits is essential in treating binge eating disorder, i recommend meeting with a dietition and a counseler to get a better idea about this, quickly .. Learning coping mechanisims and working on portion control is the best start to help overcome binge eating problems.
Seek help. Please consult a psychiatrist and psychologist as binge eating is difficult to fix by oneself - waiting too long often means that one has the added challenge of dealing with rapid weight gain.
