Zayn Malik shocked his devoted fanbase when he announced that he's an eating disorder survivor. The 23-year-old singer revealed the heartbreaking news in his self-titled autobiography, released on November 1.

His eating disorder manifested in November 2014 while he toured with One Direction.

"It wasn't as though I had any concerns about my weight or anything like that, I'd just go for days — sometimes two or three days — without eating anything at all," he wrote in the book. "It got quite serious, although at the time I didn't recognize it for what it was. I think it was about control. I didn't feel like I had control over anything else in my life, but food was something I could control, so I did."

While Malik's confession definitely astounded those who've followed his career, it also continued breaking down the stigma around men and eating disorders.
