After filming War Dogs, Hill asked his 21 Jump Street costar Channing Tatum for some fitness tips.

"And he said, 'Yes, you dumb motherf--er, of course you will. It's the simplest thing in the entire world."

The Oscar nominee has credited clean eating for his incredible weight loss. "It was just mostly diet," he told ABC News in 2012. "I wish there was some crazy thing that I did, like a pill or a genie or something. ... 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."
