This is going to sound bad, but back in October I sat my ex-fiance/now boyfriend type thing (who was a meat and potatoes only kind of guy) down and said:

"I love you, and even though women typically live longer, I don't want to out live you by twenty years or more. Please eat some veggies that are not full of starch, and please be more conscious of what you eat. Your metabolism is going to slow more as you age, and your eating habits are already affecting your appearance. I love you no matter what, but you've said you don't like the fact that you're putting on weight. A more balanced diet in addition to your current workout will go along way."

He still eats mostly meat and favors potatoes, but he will eat more veggies and fruit if it is around. He also stopped eating fast food all the time and started buying leaner cuts of meat and drinking skim milk. While that isn't a huge change, it's a change that he's managed to stick with.

I agrree with KDDani. I've been dating my boyfriend for nearly 5 years now. When we started dating, he had the worst diet in history ,was a very picky eater, hated veggies/fruit and had never eaten a salad. It frustrated me at first, but over time, we've both changed our diets for the better by trying new things together, working out together, and sharing meals at places where the portions are huge (see also: Mad Mex burrito). It can be frustrating, but my suggestion is maybe make the option available, but don't push it.

I just started cooking meals instead of going out. If he didn't like it, he could go get something else. Living in a small town like mine, there are few options (Dairy Queen and Mexican places get old after a while) and he gets lazy and doesn't want to go get anything else. He also hates to grocery shop. So, he eats what I make or he fends for himself. It is working pretty good.

Hang out with people who are vegetarians and know how to cook veggies etc to make it really delicious...not just steaming stuff. I went to a cookout w/ the ex a few years ago and we didn't notice till afterward that except for the wings, the whole cookout was vegetarian because everything tasted so fantastic.

Very good point. And maybe he just doesn't like her cooking.

I think it is a requirement...if you're veg or vegan, you've got to be a good cook. A friend of mine I stayed with in Scotland was a strict vegan, and with the exception of his tea (decaf tea w/ soy milk= not good), was an amazing cook. He just whipped these awesome meals up from stuff that you wouldn't think of combining...and he made the best Thai green curry I've ever eaten. I refused to eat mushrooms until he made them in a stir fry for me...delicious. Since coming back to the states, I've gotten much more adventurous with veggies, even exploring the treacherous world of asparagus (mmmm).

And if all else fails, use olive oil, I swear, it's the solution to every culinary problem.

I love asparagus. I have some great recipes for it.

When I moved in with my husband I did the cooking, so I would just prepare veggies and more healthy choices. We found out that way what he did and didn't like.

But 9 months in... I might just go the route of plate sharing. 9 months is still early in a relationship - we were on year 6.
