Our televisions bulge with weight-loss shows, as the news warn of the obesity epidemic. Fat is such a villain that larger people are stigmatized and we all are seduced by life-changing claims of a multi-billion pound diet industry. Yet, when we question if our bathroom scales can really tell us about our health, we start to ask just why and how fat holds such fascination.In this book, Jayne Raisborough explores interpretations of fat bodies from Palaeolithic Europe to Poverty Porn TV to argue that fat's materiality makes it ripe for stigmatising associations. However, especially in a social context that presents health as a matter of choice, fat also emerges as an ideal redemptive substance to be pummelled and starved into submission. This book presents a `fat sensibility' to demonstrate how fat is helping us all become responsibilised healthy-citizens. It asks just what self are we being asked to diet ourselves into?
