Hang in there. When you find yourself taking one step forward and two back, crank up the music, you just learned to line dance!
You have to reframe your thinking, it is not an easy task, but can be done.
As far as kids, spouses, etc., eating the yuk food, they most likely do not need it either. Make it a mission to slowly wean them off that junk.
There are tons of fun ways to eat fresh, crunchy veg! Even my veg hating husband, who had never eaten a veg other than a green bean for the first 20 years of his life, now likes salad, and fresh cucumbers, and tomatoes, and even asks for more veg!
Took me awhile! But I did not give up! I did let the kids have some junk, but that was the now and then. It was so funny when I caught my 5 year old hiding in the closet, eating the green pepper, I told him not to eat because it was for a holiday dish! I so could not get mad, bought another pepper.
