Zayn Malik reveals he had eating disorder while in One Direction

In excerpts from his new book, the 23-year-old says seeing pictures from 2014 makes him realise "how ill" he was.

"Something I've never talked about in public before, but which I have come to terms with since leaving the band, is that I was suffering from an eating disorder," he writes.

"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 straight - without eating anything at all.

"It got quite serious, although at the time I didn't recognise it for what it was."

It's not clear from the extracts published in The Sun whether Zayn had an official diagnosis, or got medical treatment for his condition.

He quit One Direction in March last year, having missed out on a number of appearances with the rest of the band due to stress.

Since then he has launched his own solo career, releasing his first album Mind of Mine in March and has started dating Gigi Hadid.
