On the causes of obesity and its treatment: The end of the beginning

Abstract

Over the last 30 years, our understanding of the causes of obesity has been transformed, and new, highly effective medicines for reducing weight have been developed. This remarkable progress marks an end and a beginning. By establishing that obesity is a biologic disorder amenable to scientific inquiry and rational drug development, simplistic notions about its causes and treatment should be laid to rest. The future holds the promise that additional therapeutic approaches for inducing or maintaining weight loss will be developed, and that these treatments will be tailored to different subgroups to potentially address the pathogenic mechanisms.
