The Obesity Society’s Annual Scientific Meeting has grown to be one of the world’s largest gatherings of obesity professionals at all stages of their careers, including leading obesity scientists presenting cutting-edge research. The meeting brings together the leading players in the field of obesity from world-renowned speakers, researchers and clinicians to educators, advocates, policymakers and practitioners. And, it provides essential educational and networking opportunities and is a forum for increasing knowledge, stimulating research, and promoting better treatment for those affected by this disease.

ObesityWeek is the combined annual meeting of The Obesity Society (TOS) and the American Society for Metabolic & Bariatric Surgery (ASMBS). The preeminent annual scientific and educational conference covers the full scope of the obesity issue, from cutting edge basic science and clinical research to intervention and public policy discussions that can impact the quality of life for millions affected by obesity.
