well lap-band doesn't fix the fatty mentality.  The only effective weight loss comes with self-realization of their fatness combined with a proper sense of shame for their state.  The diet and exercise stuff follow this mentality because the tools are available for FREE everywhere you look but it's truly up to the individual to seek those methods out vs. the "quick fix" of lap band. If they don't think anything is wrong with the way that they eat, they will continue to eat that way after the surgery.
