In China there exist a treatment "Use poison to cure poison". So in theory we could use another addiction to control eating addiction. For ex, we could be addicted to playing computer games all day then after a couple days we will feel that eating is very boring. I suggested choosing interactive games to play such as sports games (soccer,...) or character games (super mario,...) since they requires me to focus all my mind to control the ball or characters.
I had tried all methods to control my mind away from the desire to eat and had failed but playing games all day long had robbed me this eating desire and bring sunshine to earth.
Good luck!
If you can't be addicted to playing games , you should find a another addiction (such as studying,working in factory,...) . Otherwise, it is very hard to fight the eating addiction by your will. (Note that freedom/free time will bring us to bad addiction so find yourself a good way to use your time).
