My fiance and I are pretty honest with each how Do I get him to lose weight?

Be honest with him. If you met him that way then you can't really complain but tell him you're worried about his health or that you want to spice up your sex life and you've noticed he doesn't initiate it like before. YOu have to be honest...We can't expect men to know what we want or what we are thinking. We need to lay it out for them. Good luck.
