- Raising awareness and improving access to prevention and treatment of the disease of obesity
- Providing evidence-based education on obesity and its treatments.
- Fighting to eliminate weight bias and discrimination.
- Elevating the conversation of weight and its impact on health.
- Offering a community of support for people affected.
Your support fuels our mission. When you participate, advocate and donate, you help us to create a better world for the more than 93 million Americans affected by the disease of obesity.
