First, i do enjoy the difference of your thread to others. Its very psychological. I like that. (It shouldn't be a surprise since you are studying the subject).
Second, about calories. I've done it once. I don't like it either. I'd rather think in food types and and portions sizes. I think its a lot easier and a lot saner. So that's what i do. Though i do look at labels and keep an awareness of how many calories are in things. Not that i know the numbers. I think counting calories once helped me in this. Its important to understand the difference in calories between fats and other types of foods. AFter you've grasped that idea, you've never any excuse for eatting too many fats on a diet, right?
Third, as to caring or not. I think this is the thing that matters. If you have a binge and you still care, you can bring yourself back to the right path. Once you stop caring, you will stay wandering, lost in the forest, so to speak. I may not ever bother counting calories again, but i have understood that i will always have to be vigilant about what i eat and my weight. I am willing to be always vigilant. If something happens and i am not able to maintain vigilance, i will fall back into that state of not caring and then It will just be a matter of time before i get to caring again and resuming vigilance.
(note by caring, i mean caring enough to do something about it.)I think as someone who suffers from depression, its important to keep on top of that too because when things elsewhere in life go wrong and i get depressed, that's when i will stop caring and lose vigilance.
