I can't even imagine being willing to make separate meals. As others have said, cook dinner, and don't apologize for it. If he's old enough to get married, he's certainly old enough to turn on the stove and fix his own food if he doesn't like what you've made. And if you do get left with two servings of food, just stick the other in the fridge for the next day's lunch. That's one less meal for you to make. (OK, two--his dinner & your lunch.)

I had the same problem too, but I guess I'm devesious. I just don't tell him i'm dieting. I make the meals and he can eat them or not. I usually do add something that he likes that may be a little too high calorie for me, but I do try to make a lot of the meals I always made, just try to cut the calories in them. A long term diet doesn't have to be just "grilled chicken". I make baked chicken with campbells cream of chicken soup (gravy) low fat of course, add some mashed potatoes (no butter, skim milk) and some kind of vegetable. Dessert is every man for himself. Be inventive.
