Cheri K. Erdman

Cheri K. Erdman is an American author, educator, and body-image activist whose book Nothing to Lose: A Guide to Sane Living in a Larger Body was among the early works in the fat acceptance and size positivity movement, advocating for the dignity and health of people in larger bodies at a time when such arguments were largely absent from mainstream discourse. Erdman earned her doctorate in counseling and taught at a college level for many years in Illinois, where her courses on body image and identity drew on both scholarly research and personal experience.

Her other books include Live Large!: Ideas, Affirmations, and Actions for Sane Living in a Larger Body, a companion volume offering practical guidance and affirmations for people navigating a culture hostile to larger bodies. Her work anticipated many of the arguments that would later become central to the Health at Every Size movement and to popular books by authors including Roxane Gay and Sonya Renee Taylor.

Erdman has spoken at conferences on body image, eating disorders, and size discrimination, and her work has been used in counseling programs, women’s studies courses, and health education settings. She argues consistently that the stigma attached to larger bodies causes more harm than the bodies themselves, and that genuine health is incompatible with shame.

Her career as an educator and writer has been dedicated to creating space for people to inhabit their bodies with dignity and to resist the cultural imperatives that equate thinness with worth. She is recognized as a pioneering voice in the scholarship and advocacy around size acceptance and body liberation.
