Only Fat People Skip Breakfast

the long version

The reason why diets don't work for so many people is that they are actually binge eaters. This means that they can diet reasonably successfully until they get a taste of one of their trigger foods, whereupon they lose all self-control and eat as much food as they can physically cram in. The result is that a binger will be on a permanent see-saw of weight loss and weight gain, accompanied by varying degrees of guilt, anger, depression and frustration.
