What is ObesityWeek®?
The Obesity Society’s annual meeting brings together cutting-edge basic and clinical research, state‑of‑the‑art treatment and prevention strategies, the latest advances in advocacy and public policy, real-world insights, and meaningful collaboration to move the field forward.
Because obesity is a complex chronic disease, effective treatment requires a multidisciplinary approach. ObesityWeek brings together the full spectrum of obesity science—from basic research to translational studies and clinical application, to policy and population health.
