(Cover) - EN Showbiz - Jonah Hill has opened up about his stunning weight loss, saying it was important for him to drop some pounds so he could become "healthier".

The actor, who is well recognised for his large frame and comedic talent, looked decidedly thinner when out promoting his new movie over the weekend.

Jonah told the LA Times that he was not sure how much weight he had lost but said he began working out and changing what he ate because he "thought it was important to be healthier".

"It's not fun," he said of his weight loss journey. "I wouldn't say it's the most fun endeavour I've ever taken on in my life, but it's important. And I'm enjoying it."

He also said he's already noticing how his change in lifestyle has affected his taste buds.

"If I eat something unhealthy now, I kind of feel a little weird and my body hurts," he mused.

Jonah has a lot on his plate work wise and is set to star in the upcoming film adaptation of hit Eighties show 21 Jump Street and appears alongside Brad Pitt in Moneyball. (C) Cover Media
