I concur with CG on this. I have been told to loose weight by friends, family, strangers, coworkers, and 3 doctors. It did nothing but make me feel worse about myself. It wasn't until I made the decision to loose weight that I did.
It's not an easy decision, and it's not a temporary one, it's a lifestyle change. Some people find it easy, some find it hard, and others find it impossible. But ultimately, it is up to the individual to make the call, not someone else.
