Added pressure
He's killing himself. Always pushing himself to lose the weight. In his head, he feels like he will gain acceptance once he loses the weight and is more attractive.
We all make up stories in our heads about the one thing that's missing. If we just solve that one problem or if he wond and pular thing came Improving is important, improving with balance is even more important. If the string is too tight it will eventually snap. Be kind to yourself. You are trying and the only person you have to prove yourself to is yourself. Only you know what you've personally gone through.
Don't put added pressure on because of others.
