The rapper admits that he went running because he wanted to look as emaciated as Christian Bale in 'The Machinist', saying '(I was) just replacing one addiction with another.'
Eminem swapped his drug addiction for a running obsession in 2008 and reveals he secretly wanted to look as emaciated as Christian Bale in "The Machinist". The rapper piled on the pounds at the height of his drug dependency depression in 2007 and chose to become a runner to lose the weight as part of his rehab.
He tells Rolling Stone magazine he would run up to 17 miles a day and became obsessed with the way he looked. He explains, "(I was) just replacing one addiction with another. I had days where I could hardly walk. In my mind I was trying to get down to - what's his name, in 'The Machinist?' Christian Bale, which was really f**king stupid."
"But I'd get a number of calories in my head I needed to burn, and no matter what, I would do it. I have a slight bit of OCD (obsessive compulsive disorder), I think. I'm not walking around flipping light switches, but when I say I'm going to do something, I have to do it."
