When it comes to what I find attractive physically in guys, it has become more about moderation. I don't find obesity to be attractive just as I don't find starved bodies to be. If it is down to a medical or poverty issue, then that gets my sympathy but I still won't find it attractive. It's even less attractive when done deliberately.

On the other side, I actually don't find really bulked up guys to be attractive. It's just lumps of muscle, and some bodies really start to look deformed when overdone. But you'd have to go on steroids or go to extremes for that look. 
These things can work for certain sports or other competitive things, but it won't make me find that attractive. I would have to overlook it and try to find other points that i do find attractive which I have done before.
