Warren Buffett is a big practitioner of this kind of diet. In his biography, there is a segment about his dieting habits and he used a two pronged approach: 1. Calorie restriction but eat a food he loved - so ice cream or milk shakes all day one day. 2. Make it so if he didn't stick to the diet, he'd have to pay one of his friends a large sum of money. The combination of greed and eating what you love seemed to pay off in terms of keeping his weight in line.
