'Well... I'm even older than you are! I keep my weight as low as possible. (We're not supposed to post specific numbers in this forum, so I won't say what I weigh. I weigh myself every morning. And if I see I'm gaining weight, I cut back until I've lost it. There are a number of reasons for this. I won't go into all of them.

I don't think this is a self-harm issue for me, although I have struggled with self harm issues in the past. We're always told that being thin is healthy to a point. I'm not sure at what point losing weight turns from being a healthy pursuit into a self-harm issue. But I presume there is one. It's an interesting question.
