The fat acceptance movement is a fat activist movement (inspired by feminist values that push against thinness being the default for women) that challenges negative attitudes toward those who live in fat bodies. The movement pushes for changes in how people of size are treated. For example, fat activists confront and reject the pervasive (both public and veiled) discrimination against people of size in healthcare as well as sizeism in the fashion industry.
