Jonah Hill Dramatic Weight Loss Photos

Jonah Hill is known for his roles in the hit movies Superbad and Get Him to the Greek, but audiences might see him looking a bit different after his dramatic weight loss.

The actor had set a goal of losing 30 pounds before filming 21 Jump Street, Us Weekly reported.

Hill said he gained weight at first, but then lost it after he enlisted the help of a trainer and a nutritionist.

I wouldn't say it's the most fun endeavor I've ever took on in my life, he told the Los Angeles Times, although he did say he was enjoying it.

The weight loss has also had an interesting effect on Hill.

If I eat something unhealthy now, I kind of feel a little weird and my body hurts, he told the LA Times.
