My FI has finally decided to start "dieting" which consists of him not eating. It's really stressing me out because we all know that, even if he loses weight, it'll just come right back. It's also unhealthy. His argument is that that's how "he's always done it" and that at least he's doing something instead of nothing. i realize i can't control what he does but does anyone have any insight on how to tackle this? i just want him to be healthy. thanks in advance
