I suspect there is no one-size-fits-all solution for obesity: some people experienced sustained weight loss only after undertaking a vegetarian diet, some only by a ketogenic diet, some only by getting into sustained exercise, and some only by a laproscopic band. For some people, obesity isn't even associated with poor health.
