How do I get my boyfriend (21) of 4 years to lose weight?

When we first met he was about 164lbs (he’s 5’10) now he’s just around 223lbs? A doctor has already told him he needs to lose weight for his futures sake. The doctor told him to lose some weight and to call him after 6 weeks. Well my bf never did. He currently in college online classes just started up and he works 6am-5pm. I keep

Begging him to lose weight, I’ve begged him in every way, We’ve even gotten into fights. His excuses are

-he doesn’t have time

-he doesn’t feel like it (he won’t admit that)

-he has school work

-it’s too late

-I’m not doing cardio I wanna do weights only (he wants to get muscular but doesn’t lose the weight?)

There’s more but ~~~

Anyways, how do I get him to lose weight? I’ve begged and begged nothing works. I’ve even given him “tough love” but he sees it a different way. He grew up as a chubby kid but lost his weight from playing soccer. What do I do now?

(We’re in a long distance relationship right now So I can’t do what I would want for him, I can only use my voice)

EDIT: people in the comments are telling me to love him the way he is. I do! I actually prefer chubby guys. But I will not let him die. The doctor told him he has a higher risk of a cancer if he doesn’t change. And he only went to the doctor because is side was hurting him bad and it was because of his weight. He’s obese and it’s affecting him. He wants to lose weight, he’s insecure as hell, wears double shirts and a hoodie to hide his “man boobs”. He wants me to lose weight too. So I’ve joined him in this, but I seem to be the only one doing anything. He definitely has the motivation, it’s the actual doing it part that just doesn’t come into play.
