Sofie Hagen has announced that she is writing a book about fatness.

The award-winning Danish stand-up comedian has been signed up by 4th Estate to write FAT, an "intelligent, funny, provocative response to body shaming".

Her debut book, it promises to call-out those endorsing weight loss, as a "celebration of the fat body, and an agenda-setting call to arms to eradicate fat phobia", and "bust dangerous societal misconceptions about what constitutes a 'good' body and demand a redefinition of our current standards of beauty".

According to industry publication The Bookseller, the book will see Sofie share her experiences as part of the fat positivity movement, speak with fat liberation champions, describe how she ended a negative relationship with her own body and provide practical tips for readers to do the same.

Hagen says: "I was eight years old the first time it was decided that I should go on a diet, launching almost twenty years of self-loathing, eating disorders and depression. I have gone from someone struggling with being chubby to someone proud of being fat, and from feeling sad because of how my body looks to feeling furious that there are people who judge me because of how my body looks.

"I am so incredibly honoured that 4th Estate is willing to give me this chance, because I genuinely believe that if I had read this book when I was a teenager, I would have had a much better life from much earlier on, so that is what I am doing: I am writing this book for my teenage self."

Sarah Thickett, assistant editor at the publisher, adds: "I've been a huge admirer of Sofie's for a long time: her work as a comedian and podcaster is so original and intelligent, never afraid to shy away from complex issues, but also devastatingly funny and feminist. FAT will examine the overwhelmingly toxic consequences of body shaming, but also how to find self-acceptance outside of the ideals it promotes.

"I'm delighted that readers will now have a chance to enjoy Sofie's incredibly frank, funny and courageous debut, which introduces such an important new voice into this timely and urgent debate."

FAT will be published in Spring 2019.
