<human>: Summarize the given text in a few sentences.

My boyfriend is receiving injections to "help him lose weight easily." He's mentioned being self-conscious about his body and I think weight loss would be fantastic for his confidence and his health. And although I'm definitely attracted to him as is, I think he'd look a lot better without so much excess weight. I've avoided the topic though, since he seemed interested in losing weight without me saying anything (so why hurt his feelings unnecessarily right?)

My issue is that he is horribly sabotaging his own weight loss. He will take the elevator for 1 floor. He will eat past when he admits to being full, apparently just for the sake of finishing (this happens often). He eats fast food on a daily basis. It's painful to watch, really.

I'm opposed to the injections, honestly. They seem like a really lazy way to handle a health issue. I think I'd be able to put up with the injections if he made an effort as well, but its infuriating to watch him treat the injections like magic fat removers.

I brought it up once and he kind of shrugged it off. His attitude was basically "yeah, you're probably right.." but then went back to the same thing. I don't want to nag him too much. I've already been on his ass about needing to get a job, so I'm afraid additional nagging will be bad for the relationship. He already has a mother and sister who nag him a lot and I don't want to be another critical opinion in his life.  We've only been together for about 6 months, so maybe it's just not my place.

Should I just shut up? Should I bring it up again? What should I say differently, if I do?
<bot>: Boyfriend receives "weight loss injections" and then eats horribly. Worried I nag him too much as is, don't know if I should say anything.
