I'd really recommend reading Eating in the Light of the Moon too Carrie.
Bingeing can have many causes. Most often the main reason people end up bingeing is (amazingly) because they are hungry! Consistently trying to lose weight, restricting food and depriving your body of the nutrients it needs...there is only one natural outcome for most people, the biological command to eat will win-but by that point, reason has flown out the window and we reach for rubbish that still doesn't give us what we need. Added to which we feel guilty and horrible, a failure because we don't have enough willpower. When what you actually have is a properly functioning body (once you can genuinely and consistently suppress hunger you are in a whole different area of even more serious issues, such as anorexia). And the spiral continues.
So start from a point of view of trying to make sure you give your body good food, the stuff it needs, regularly - three meals a day, each with protein, good fat, whole foods. Eat them slowly, pay attention, enjoy. Feel your hunger, try and recognise satiety. Forget about calories/portion size/carbs or fat, it's just for a short period. Also pay attention to how you feel after different meals. Energised, sluggish, poor digestion?
Many people find the need to binge disappears simply by eating properly, letting go of the diet. If not, then you can begin to identify the triggers that are related to emotions etc.
