I stumbled on a nice anti-weight-loss site a few days ago called bodypositive.com It has some good resources, although it hasn't been updated in a while. But something that caught my notice were these door hangers. Talk about a great back-to-school item! You can write to the site and get some for yourself. I think they would be perfect at any dorm, and would help students stop worrying needlessly about the "freshman 15" but instead feel good about themselves if they get curvier at school- where their parents aren't nagging them any more.
I think this message applies to this website as well.
