Natalie Hayden, 21, of Lexington, Ky., has been naturally thin her entire life. “People have always made comments, like, ‘Oh, are you anorexic?’ or ‘You look like an Ethiopian child.’” Hayden believes most of her friends mean no harm, yet sometimes the remarks dig deep. “I remember when the ‘Zero is not a size’ campaign started and it upset me. It is; it’s my size. They made me feel ashamed, like I don’t exist.” BY KAYLA GRORUD
