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. 

TOS publishes two journals, including the leading peer-reviewed scientific journal in the field, Obesity, and an open-access journal, Obesity Science & Practice. 

The preeminent international conference for obesity researchers and clinicians, ObesityWeek® is home to the latest developments in evidence-based obesity science: cutting-edge basic and clinical research, state-of-the-art obesity treatment and prevention, and the latest efforts in advocacy and public policy. Overcoming obesity requires multi-disciplinary approaches. This is the conference that encompasses the full spectrum of obesity science: from basic science research, to translational research and clinical application, to public policy; from diet, exercise, lifestyle, and psychology to medical and surgical interventions; from pediatric to geriatric to underserved populations. 

TOS is engaged in many other efforts to serve our members and the field, including our nearly 50 grants and awards, weekly news distribution through our eNews, political advocacy and clinical education.
