If you over eat, try to control your thoughts by immediately change your thought pattern you get the urge and substitute a different image, perhaps, if you overweight then you look like a Bond girl stay with that thought and any consequences that come to pass until the urge passes. Do this continually and the urges will disappear. (if you are a man, become your favourite 007 for a while !! - that shouldn't be a difficult distraction.
