  • 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.
