This is Big : How the Founder of Weight Watchers Changed the World (and Me) Hardback

'A life-changing book' Viv GroskopMarisa Meltzer was put on her first diet aged five: it was the beginning of a fraught relationship with food. Jean Nidetch was a housewife from Queens who defiantly lost 70 pounds after she was mistaken for being pregnant.

Taking everything she learned from this experience, in 1963 she founded Weight Watchers, a company that has shaped decades of diet culture. When Marisa reads Jean's obituary, she feels a moment of intense connection.

Curious about the woman and her legacy, she signs up for a year of Weight Watchers; counting points, weighing in and listening to her fellow members struggle with their bodies. This is Big is a biography of an idiosyncratic entrepreneur whose impact is still felt strongly today.

It is a history of dieting and body politics for anyone who has agonised over their weight or defiantly tried not to do so. And it is Marisa's funny and thoughtful journey towards a different way to live in the world. 'This is the anti-diet book I've been waiting for' Daisy Buchanan
