He was having the time of his life in one of the biggest boy band in the world but it seems things where not so rosy for Zayn Malik while he was in One Direction.

Now in his eponymous autobiography what is set to hit the shops soon it will tell all about his time in the band and his health troubles.

Writing in his book he said:

‘When I look back at images of myself from around November 2014, I can see how ill I 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 continued:

‘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.’

When you look back at the photos he really didn’t look well at all.

No one know about his eating troubles so this has came completely out of the blue.
