I readily agree with the need for patience and persistence. But notice the one thing that is missing from that requirements list - for good reason - willpower.

With other diets you usually have to have superhuman levels of willpower to fight your body's demand for nurishment and to feed its carb addiction. On an LC WOE you need for willpower is very low once you make it past a couple of weeks. You are working WITH your body. You still have the frustrating times and you still have long time horizon to the final goal (for members of this club) and so you definitely need the patience and persistence, but that really is enough in most cases.
