Thanks for the advice. In my experience, honest concern has been the most effective way to encourage him, but it didn't last. It's like every time I think I'm getting through to him, he just reverts back a few weeks later (and it's always weeks, never months). I still hope that one of these days he'll change, but I just don't think I can be a part of it. I told him as much the last time he tried to lose weight. The fact that he still expects my help after that is seriously pissing me off (obviously lol).
