To live in a body at the intersection of fat, Black, and female is to be on the margins. From concern-trolling—"I just want you to be healthy"—to outright attacks, fat Black bodies that fall outside dominant constructs of beauty and wellness are subjected to healthism, racism, and misogynoir. Fat Girls in Black Bodies breaks down the myths, stereotypes, tropes, and outright lies we've been sold about race, body size, belonging, and health. Cox's razor-sharp cultural commentary exposes the racist roots of diet culture, healthism, and the ways we erroneously conflate body size with personal responsibility. She explores how to reclaim space and create belonging in a hostile world, pushing back against tired pressures of "going along just to get along," and dismantles the institutionally ingrained myths about race, size, gender, and worth that deny fat Black women their selfhood.
