Chapters examine the racist and colonial constructions of Western beauty norms as well as the evolution of anti-fat bias and fat liberation, before delving into the relationship between social media and body size activism, with a particular emphasis on social media companies censoring fat people. The authors draw on first-person narratives of artists, activists, and fat social media users to unpack how, these mostly women, have used their bodies to transform the negative social perceptions of fat people.This book will be of interest to scholars and students in Sociology, Gender Studies, History, and Media Studies who research body size activism and beauty norms.
