My DD has been on a diet since December. She was slightly overweight for her height when she started, about 10 and a half stone, but now she's 8st 6 and not planning on stopping dieting. She lost it by eating healthily at first but this week alone she's lost 3lb, and just won't eat a lot. She had a period where she was about 12/13 where she would make herself sick to try and loose weight, but I thought it had been sorted after some therapy. I don't know what I can do, she's not little anymore and I can't make her eat but I'm just so worried.
