Emotional eating is a big one for me. (no pun intended)
I've found that the exercises in the book "
The Four Day Win" has really helped me to identify and disassociate myself from some of those emotional triggers. It deals not so much with a diet, but rather how we motivate ourselves (and sabotage ourselves) in any life-change, and gives tools for identifying and dealing with the cycle.
For instance, one of the exercises I go back to over and over again has me identifying the "health dictator" part of me who wants me to stick by a draconian diet/exercise regime, and listen to her. Then identify the "wild child" part of me that wants me to eat enough to take care of myself in situations of famine, flood, and disease, and listen to her. And then to "step back" and observe, and LOVE, both of these parts of me. When I become "the watcher" rather than the dictator or the wild child, I remove myself from the conflict itself. I can more calmly observe and assess both sides, and appreciate both sides, so they are no longer at war in me (at least for that hour or so). But the more I do this, the less I am likely to binge, to eat for no reason, to find myself with a box of Cheezits in hand and not remember getting them, etc.
It sounds pretty touchy-feely, psycho-babble, doesn't it? I was really skeptical when I first began the book (and didn't do the exercises wholeheartedly until my second read-through). But I can't argue with the results. I'm amazed at how much less emotional my eating has become.
