About Us

Our Story

The Obesity Care Advocacy Network (OCAN) was formally announced during ObesityWeek® 2015. Our founding members formed an advocacy network to change how we perceive and approach obesity in the U.S.

OCAN works to increase access to evidence-based obesity treatments by uniting key stakeholders and the broader obesity community around significant education, policy and legislative efforts.

What We Do


OCAN’s mission is to change how the nation perceives and approaches obesity in the United States. We seek to elevate obesity on the national agenda by uniting and aligning obesity stakeholders and the community around key obesity-related efforts.

Who We Are

OCAN is a diverse group of organizations that have come together to change how we perceive and approach the problem of obesity in this nation.

Working Groups


The Congressional Advocacy Priorities and Strategies (CAPS) Workgroup advocates for policymakers to pass legislation, including the Treat and Reduce Obesity Act (TROA), that supports coverage of and access to obesity treatment, prevention and care.
