I think there is still alot to be learned about eating disorders. I am a recovering binge eater. I would get stress, upset and then secretly eat everything. I sometimes would eat so much that it make me sick. I wasnt trying to throw up it would just happen. Sometimes it happened because of the guilt.

I was very upset about my weight and wanted something to work. I would not eat for days. One time I only drank protein for 14 days. I loss a little over 20 pounds in that time frame. However of course it all was gained back when I resumed eating "normal" again.
I tried to talk to my dr about what was happening. I dont think he understood my concerns and cries for help.
I finally went to a different dr. This dr did a ton of test on me to see if I was healthy, etc. Afterwards the dr told me that he did feel I had some food related problems. He suggested that I go to a nutritious. That seemed to help some. Later I found out that all my crash dieting has caused my metabolism to slow down. That I basically screwed up my own system by all the bad choices I have made.
At one point I was taking 15-20 diet pills a day. I think that was when my dr finally realized that I needed help. He was concerned what these pills were doing to me.
I am now on weight watchers. I have learned how to eat, what to eat. The meetings are a source of support for ppl who have been there just like me. Plus they understand all the crazy things I've done out of desperation to lose weight.

omg, I have gone on so many crash diets, I can not even count them, and yes I loss the weight but it all came back again, and again and again. the last diet that worked for me was a high fiber (25-30 grams)and lots and lots of water(yak) that was all i counted, it stayed off until I had my neck surgery, but I preey much stayed with that diet, but the diet was for other med. reasons weight loss was a plus
