The National Association to Advance Fat Acceptance (NAAFA) is a U.S.-based non-profit organization founded in 1969. It is dedicated to advancing fat acceptance as a civil rights issue by eliminating body size discrimination and empowering individuals through advocacy, public education, and community support. NAAFA originated in Rochester, New York, and has evolved into a multigenerational social justice group that addresses fat discrimination in various aspects of life, including employment, healthcare, and education. NAAFA's core activities include advocacy campaigns like the Campaign for Size Freedom, public education initiatives that promote fat acceptance, and community building for fat individuals and their loved ones. The organization provides resources for self-empowerment and fosters connections through events and social media. NAAFA positions fat activism within the broader context of social justice, challenging negative perceptions of larger bodies and promoting dignity for people of all sizes.
