I'm not great at doing healthy things, but one thing I try to do is, even if I'm eating something unhealthy, if it has veggies, eat more of the veggies so I eat less of the less-healthy stuff. I had Chinese food the other night (and leftovers last night), General Tsao's Chicken. This dish includes big pieces of broccoli mixed in, and while the sauce may not be the healthiest, the broccoli isn't usually covered that much in it, so I try to eat plenty of the broccoli, and less of the chicken (which has plenty of the sauce, and it's fried). Filling up on veggies is a good way to help yourself eat less of "the bad stuff."
