answer:I grew up as a chubby guy, and I would take the following approach if I was in your shoes: Tell him you, as a female, are more interested in the intangibles than men are. You care about the whole package. Tell him you find him attractive and want to be his girlfriend, but you wished he would focus more on his health. You think men who take care of themselves show a depth of character men who don’t lack. You dig him a lot, but you care about his health and you want him to focus as much on taking care of himself as he does on other things. You can’t stick around forever with a guy who doesn’t take care of himself, it is almost like he doesn’t like himself somehow, and it makes you wonder what is going on.
