Angry at husband for refusing to take care of his body

I just got married in September, and at 46, my husband is slightly overweight and is becoming very unhealthy. I just looked at his lab results from his recent check-up and he's pre-diabetic and has high cholesterol. I want to have at least 40 years with him, and I DON'T want him to become diabetic and lose limbs, have ED, have to inject himself with insulin, etc.

His sugar crashes are AWFUL when he goes too long without eating. He's grumpy, forgetful, etc. I have diabetics in my family and I've seen the terrible damage it does and how badly it brings down the quality of your life.

The thing is, he "talks" change, but does nothing. I get on the elliptical and he says he'll get on after I'm done, but then he gets busy doing something else and doesn't do it. He eats HUGE portions of food, especially carbs, and he's a chocolate junkie.

I could, since I'm really the only one who cooks, make only healthy meals that he won't be tempted to eat too much of, but I think he should just learn damn portion control. For example, tonight I'm making tuna and noodles and a vegetable. My kids love it, and I know how to eat only a small portion (like a cup) and fill up on vegetables. My husband, however, will eat a HUGE plate, and a tiny dollop of vegetables. Plus he'll drink a big glass of orange juice with it. I'll drink water or unsweetened tea. I don't think it's fair to have to make only "health foods" just so that he doesn't have to worry about trying to control himself.

Plus, I'm angry that he leaves it all to me. I don't want to have to tell him to work out or tell him to only eat so much of something or only make certain foods. He's a grown man, and should be able to self-monitor.

We are trying to have a baby, and I want him to be around well into old age to see that child grow up! I love him so much that it angers me that he cares so little about his own health.

Should I nag him? I remind him to work out but then don't get on his case if he doesn't, because I don't want to seem like a controlling bi#*ch. I don't say anything when he overeats, but I frequently remind him he should eat less carbs (because of the blood sugar issues) and more vegetables and protein. But I haven't come down on him hard, it's just been suggestions.

As a side note, I AM attracted to him, so I'm not doing this because I want a hotter husband. I do think it would improve my desire for him some though if he were a bit slimmer and more muscular. It's not that big of a deal though, more like a "wouldn't it be nice" type of wish than anything. I mostly want him to be healthy!

Please, any suggestions would be appreciated.
