For as long as she can remember, Kate Manne has wanted to be smaller. She can tell you what she weighed on any significant occasion: her wedding day, the day she became a professor, the day her daughter was born. She’s been bullied and belittled for her size, leading to extreme dieting. As a feminist philosopher, she wanted to believe that she was exempt from the cultural gaslighting that compels so many of us to ignore our hunger. But she was not.

Blending intimate stories with the trenchant analysis that has become her signature, Manne shows why fatphobia has become a vital social justice issue. Over the last several decades, implicit bias has waned in every category, from race to sexual orientation, except one: body size. Manne examines how anti-fatness operates—how it leads us to make devastating assumptions about a person’s attractiveness, fortitude, and intellect, and how it intersects with other systems of oppression. Fatphobia is responsible for wage gaps, medical neglect, and poor educational outcomes; it is a straitjacket, restricting our freedom, our movement, our potential.
