I lost weight by measuring calories, shedding ~25% of my body weight. It's still a battle and will always be. I keep exercising the whole time - I'm training for my first marathon right now (I've run the distance before, just not in an official race), but my weight slides up, I adjust, it slides back down. I think some people are just built to like food, it's not a matter of education.
