Anonymous wrote:OP here - thanks for all the advice so far. I should have been more specific: Both my other child and myself are in excellent shape. Honestly, I know more about fitness and food than most people. Perhaps that is where the problem lies - I make too much of a big deal over exercise and eating right. I have some junk food in the house, but not a lot. I made nothing forbidden because I didn't think that was the right way to go. I model the right behavior, but it has no impact. Because I also have a diet-obsessed mom I go out of my way not to specifically talk about diets, but about healthy eating. I almost feel like I'm doing her a disservice by *not* talking about it, but I'm afraid. I'm sure she knows! That's why I was thinking about a professional; I would still have to figure out a way to get her there, but it wouldn't be me doing the talking.
Well, how is she doing otherwise? It is so hard to opine about this on an anonymous internet forum and not sound like an uninformed jerk (and I swear I'm not trying to be), but is she otherwise well-adjusted and healthy? Is it from bad habits or is it possible she's just made this way/going through puberty differently than you and your other child did? Is it possible that there's something else going on with her emotionally? Is it a control thing for her, maybe? Subtle subconcious rebellion? There are so many possibilities. Has SHE ever mentioned it?
