Oh man, I am 100% behind this post. Hearing stories like this make me both incredulous (I've been so lucky as to be in not just a family, but an environment, be that school or work, where eating is relatively angst-free) and sad, because -- why? The situation which you describe is -- it's ridiculous and it isn't healthy.

One thing I wouldn't agree about, though, is maybe what you named your tag. It isn't even about weight. Like you said, it's a body issue.
