In her latest book Unshrinking: How to Face Fatphobia, Kate Manne, Ph.D., an associate professor of philosophy at Cornell University, delivers a definitive takedown of fatphobia, drawing on personal experience as well as rigorous research to expose how size discrimination harms everyone, and how to combat it.

Blending intimate stories with the trenchant analysis that has become her signature, Manne shows why fatphobia has become a vital social justice issue. She 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.

In this urgent call to action, Manne proposes a new politics of “body reflexivity”—a radical reevaluation of who our bodies exist in the world for: ourselves and no one else. When it comes to fatphobia, the solution is not to love our bodies more. Instead, we must dismantle the forces that control and constrain us and remake the world to accommodate people of every size.

Manne will be in conversation with Roxane Gay, Ph.D., a contributing opinion writer for the New York Times and the acclaimed bestselling author of Bad Feminist, Difficult Women, and Hunger. Gay is also the author of World of Wakanda for Marvel. She has a newsletter, The Audacity, and once had a podcast, The Roxane Gay Agenda.
