Why did he send me a pic saying he needs to lose weight did I make him feel bad about himself?

Make him? Not likely. It is more likely he already felt that way. Seeing you likely made him take an ever longer look at himself upon seeing your level of fitness and he just voiced it. That you stick around you obviously like him on some level. Perhaps offer to a part of this weight loss he knows he needs to do. It might be a better approach then trying to reassure him or whatever.
It is more likely that he felt bad for being that way, specially since you have a nice body. And maybe wanted to show before things got more serious between you two.
Could be that he trusts you now enough.
In any case, it is highly unlikely that it has anything to do with you. Because then, he would not have sent the pic.

You'd have to ask him. Maybe he wanted your feedback? (ie not directly asking "do you think I need to loose weight?).
