Noun

Also known as anti-fat, is the implicit and explicit bias of overweight individuals that is rooted in a sense of blame and presumed moral failing. Being overweight and/or fat is highly stigmatized in Western Culture. Anti-fatness is intrinsically linked to anti-blackness, racism, classism, misogyny, and many other systems of oppression. 

Anti-fatness contributes to individuals not receiving adequate healthcare for a number of reasons, 1) the assumption is if someone is overweight they cannot be healthy, 2) clinical care teams typically lack experience in treating diverse body sizes, 3) weight related structural barriers, e.g., size of exam tables, gowns, blood pressure cuffs, and scale limits.
