Find an occupation or a hobby which require quiet a while and your full concentration!
By concentrating on other thinks than food you can get your head free and you might be able to ask yourself: "Do I really need to eat this? What is the sense of eating all this stuff?"
This might not be the most "healthy" solution, but by pushing your obsession from food to your hobby, e.g. sport, painting or blogging ;), you might be able to escape out of your binge eating!
Everyone has an obsession and nobody says something against an obsession for makeup or painting, so why not pushing your obsession to another way.
