Photographing while fat: Turning the lens on those who stare
BBC 13 December 2015 Last updated at 00:23 GMT
Haley Morris-Cafiero has travelled the world to capture how people judge one another.
Working with an assistant, she photographs herself in various locations being leered at, laughed at or ignored by people on the street.
After posting some of her images online last year, Morris-Cafiero was met with a mixture of disgust and praise for her work.
Her book, The Watchers, collects both the photos and the online comments. After struggling with her own eating disorder, she hopes her photography can provide others with confidence in their own skin.
