If your doctor is wise, s/he will suggest therapy as changes to the actual diet will not help until the binging is under control. I have binge eating disorder, however, I did not discuss it will my doctor but instead spent about a year with a therapist that specializes in eating disorders. I now only see my therapist about once every two or three months (I was going once weekly for a year) and I have been able to get my binging under control.
Good luck.
