The Obesity Society (TOS) is the leading organization of scientists and health professionals devoted to understanding and reversing the epidemic of obesity and its adverse health, economic and societal effects. Combining the perspective of researchers, clinicians, policymakers and patients, TOS promotes innovative research, education, and evidence-based clinical care to improve the health and well-being of all people with obesity. The Society has more than 2,500 members, including researchers, healthcare providers and others working in obesity science, treatment and prevention.

ObesityWeek® is the premier annual scientific and educational conference bringing together the world's experts in obesity research, treatment and prevention - from clinicians and surgeons to educators and policymakers.
