So, Jonah Hill definitely knows he looks good!

The actor, wearing a green sweatshirt and black shorts, couldn’t stop smiling as he flaunted his fit figure on Tuesday, May 16, while taking a walk in LA. Since packing on the pounds for his 2016 movie War Dogs, the 33-year-old appears to have dropped it all, plus a little extra.

The Oscar nominee opened up about his transformation during a recent appearance on The Tonight Show. “I gained weight for this movie War Dogs and then I wanted to get in better shape, so I called Channing Tatum, and said, ‘Hey, if I ate less and go to a trainer, will I get in better shape?’ And he said, ‘Yes, you dumb motherf–ker, of course you will, it’s the simplest thing in the entire world,’” Jonah revealed.

The 21 Jump Street star first slimmed down for a role in 2011, explaining at the time, “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.”

Jonah, who became a household name after the 2007 comedy Superbad, added, “Being healthier came along with maturity and it’s hard, because a lot of times people want you to be the guy you were when they met you. And I love doing funny movies, but I want to mature, literally, in how I treat myself. I’m not living in a frat house with a bong plastered to the table… I just want to be a good man and to make my family proud. And, you know, I want to live a long time.”

Keep up the good work!
