Eating disorder is something I can relate to. I had the inverse problem though, but maybe methods could work both ways? Your doctor probably could tell you what your weight should be to be healthy, just like my doctor told me. If you are over weight they can tell you how many calories your body burns in a day, so you could count calories and try to hit the marks set by your doctor. My low self-esteem really worked against me. One of the few things I could control in my life was food. Food was good, you generally eat with people you like, you look forward to the lunch hour, holiday food, alcohol and munchies, if my day sucked, I could get brownies and milk or something that sounded good.

Three years ago I was diagnosed with ADD (43 years old) and with all the baggage ADD adds along the way, My Addiction was Food! Adderall corrected most of my brain chemistry and I just stopped focusing on my next meal. I started feeling Good, losing weight and my wife was convinced the "Speed" was the only reason. Not anything to do with ADD or brain chemistry, or the exercise I have done since my diagnosis. I DO understand why losing weight feels good to you. My wife thought I was never going to stop losing weight, but I told her if I got to a weight that was unhealthy my doctor would say something. I am paranoid about gaining the weight back, so I let my pants do the talking. "The pants don't lie"

Sorry for the ADD ramble, but maybe a weight goal based on good health by your doctor is a way to know where to set the target? My family has always battled their weight and the stuff we see on TV is just ridiculous. It destroys our self worth.

Take care...
