I think as women we always just want to make our families happy. I would eat terribly all the time because my husband didn't like what I made.
Finally I told him one day that
I needed to be selfish and think about me. If we had children I'd tell him that we need to think of our children's health and that we can't eat this way anymore.
My husband wasn't too happy with it- we went from things like fried chicken, steak, mashed potatoes, and so on each night. To things like grilled chicken with tomatoes and zuccini- and so on.
At first he wasn't too happy with it- but with time he's found things he likes and things he hasn't liked. But my husband has lost 20 lbs since all the changes and I've lost 8 so far, so it's obviously working.
I would speak with hubby and tell him that things will change for dinner and that you want him to be supportive and tell the kids eat their dinner- and hey if they don't- then go to bed hungry- pick one

it's tough love but with time they'll learn to like other things and will just eat it without fuss. I know I always ate what my mother put before me because if I didn't then I didn't get to eat anything else.
