Before the actor revealed that he slimmed down on sushi, many believed that his Moneyball co-star Brad Pitt had something to do with Hill's new leaner look.
It was just mostly diet, Hill said. I wish there was some crazy thing that I did, like a pill or a genie or something, but it was, unfortunately, I went to see a nutritionist, and he told me what to eat to change my habits and stuff... I found that Japanese food was very helpful to me.
Hill also said he had a moment in his life where he said he wanted to become a man. And that means with my career, with my life and that also means with my health.
I'm almost 30 years old - I'm not a foul-mouthed 17-year-old kid who's trying to get laid, Hill said. I'm an adult man who takes his work really seriously. I'm an actor, I'm not a comedian, I never was a comedian.
Hill has appeared in comedies such as Knocked Up, Forgetting Sarah Marshall and Get Him to the Greek. One of his most serious roles was playing a Yale-educated statistics nerd Peter Brand in Moneyball.
