Hi, Jillybean! I don't think there's any real instant epiphany, psychological, physical or behavioral, that can create perfect eating habits, whatever those are. I'll give my $.02 (which I have stated before) based on my personal experience as a person who used to be bulemic (mind AND body) and lived to tell the tale . . .
Food used to be completely an emotional item for me. Good foods and bad foods. Scary foods and safe foods. Too much food and too little food. It was all driven by my head, and I was totally out of touch with my appetite. This was true throughout my teen years, kind of went underground as alcoholism took over, and then reared its ugly head a couple of years after I quit drinking (and immediately lost, then regained a good portion of, approximately 35 lbs.). I quit drinking a few days before my 26th birthday in 1987, and after a couple of years of my body adjusting nutritionally to NOT having gallons of alcohol pumped through it on a weekly bases, I started "puffing up" again. Of course, I wasn't exercising in any meaningful or consistent way.
I've found over the past 10 years in general (when I began to move every day by walking, and them swimming, the Nordic Track, then videos, then aqua instruction while continuing videos) that the more intelligently I exercise (i.e. paying as much attention to strength and muscle mass development as I do to cardio, AND consistently increasing the cardio and strength challenges) the more intelligent my body became, and what I crave for food, both in terms of type and amount, is driven by what I need physically. Without arbitrarily telling myself I can't have this or that 'cause it's bad, or I should have thus and so 'cause it's "good", I am able now to just go with what I feel like having, and Ye Olde Bod knows what it needs and how much.
I do not weigh myself. I don't count calories, fat grams, or measure portions. During exercise, I don't take a heart rate check during my land cardio workouts. I do pay attention to the number of workout sessions I complete per week, and I log strength and cardio performance increases consistently.
I firmly believe that the more attention one pays to developing superior physical capabilities and muscle mass the less conscious "control" one needs to exercise (or exorcise) over one's nutrition beyond the basics. It doesn't happen overnight, however, and it doesn't happen in a linear way. But it can happen, and I am here to say that it does.
Whew! I hope this doesn't sound sanctimonious; I think I'm exceedingly fortunate to have found a way out of food obsession. I hope this helps a bit.
