She wants it in the "wouldn't it be nice if I was skinny???" sense, but she doesn't actually want to work for it. Not to defend her at all, but it's probably because she was just handed everything in her life and never had to work for anything. As a result, she acts like an overgrown, obese baby. Fitness is the one thing that nobody else can give you; you have to work hard to earn it yourself, and that fact is lost on her. I really hope she has a massive coronary and dies soon.
