Despite the undeniable importance of lifestyle, I've always thought lifestyle coaching is an exercise in futility. Lifestyle is primarily a behavioral issue. If a patient has the motivation and discipline to change his lifestyle, he doesn't need coaching. And if he doesn't have the motivation and discipline, coaching isn't going to accomplish anything. The majority of people who lose weight and make lifestyle changes do so without coaching or support of any kind. Furthermore, given the current state of things, I would be extremely apprehensive about trusting the medical community to be the purveryors of lifestyle, as they would probably be more prone to give bad advice than good. Look at how many physicians are overweight! Most doctors know nothing about nutrition or exercise.
