There's also a lot of evidence that whatever "will-power" is, it requires a rested, well-fed mind. Dieting fundamentally decreases your ability to have "will-power". So perhaps what we call "will-power" is only a correlative trait--not a causative one--for people who lose weight. People lucky enought to have bodies that can easily switch to consuming fat instead of storing fat will probably find themselves with a lot more energy throughout the day to be able to think clearly, exercise, and make good eating decisions, but then call their good fortune "will-power" as a result.
