ABSTRACT Fat social justice and fat liberation movements share language, symbols, and strategies with many other movements striving to fight discrimination and stigma, such as movements centered on race, gender, sexuality, and disability. These communities should be natural partners with fat activists in striving for intersectional liberation and in fighting existing structures of privilege. It is less clear, however, the degree to which fat activism and activists are welcome in spaces explicitly constructed to address comprehensive approaches to social justice. To address this question, we examine a setting specifically built to address issues of privilege, oppression, and discrimination: diversity, equity, and inclusion organizations at US colleges and universities. We compile a data set of diversity, equity, and inclusion offices at 200 four-year colleges and universities in the US, with stratified samples to ensure inclusion across regions of the US, a broad variety of educational settings from large Research 1 institutions to small liberal arts colleges, and a subset of historically black colleges and universities. We examine whether and to what degree issues of fat social justice and liberation are included in university diversity and inclusion offices, websites, and materials. Findings show fat people, their experiences, and fat social justice issues are generally excluded in DEI spaces. We provide potential explanations for this exclusion and outline possible steps forward for those interested in fat social justice.
