What would you do?

My husband has gotten severely overweight after dating me and it’s bothering me. I still love him but I’m not physically attracted to his body anymore. I wouldn’t ever leave of course but what would you do to get your partner to improve their health? I hate seeing people stuff their faces. unhealthy behavior in general bothers me and I don’t know what to do. I try to get him to workout and he doesn’t want to. He eats like 4k calories a day and doesn’t move from his desk at home. He doesn’t go for walks. Nothing. He jogs maybe once a week but still eats so much. I tried getting him to workout ( I offered to workout with him) and he snapped at me. He cries about his body and I tell him that I love him regardless of it all and that I’m his support system but he does not want to do anything to change. What should I do?
