High Quality Content by WIKIPEDIA articles! Fat feminism or fat-positive feminism is a form of feminism that argues overweight women are economically, educationally, socially and physically disadvantaged due to their weight. Instead of losing weight, fat-positive feminists promote acceptance for women of all sizes and oppose any form of size discrimination. Fat feminism originated during second-wave feminism, and has not met mainstream acceptance. While very closely affiliated with the fat acceptance movement, fat feminists focus on women who are discriminated against because of their size.
