<human>: Can you condense the text into a few key points?

my bf and i are both overweight (there's no question or doubt about that). i have several health problems, so i'm trying to become healthier and slimmer. my bf supports me and wants to do the same for himself. i admit we become lazy about it and put it off sometimes, but i think i feel stronger about it than he does. he constantly complains about his weight and denies his weight to be a factor in minor health problems that he has. i care about him and don't want him to get into any serious health problems. how can i push him to finally work out/eat better without hurting his feelings? or should i just let him do it on his own? i love him regardless of his weight, but i think we BOTH need the right motivation. he gets offended or mad if i tell him something simple, like "don't add too much salt." am i going to far by saying anything? thanks

p.s.
i hate it when my mom nags to me about losing weight, so i know how he must feel. but he has said waaay more than once that he wants to lose weight as well. i think i just need to find the right words. sorry this is long!
