Actor’s extreme weight loss stuns fans at SAG Awards

Actor Zach Galifianakis is certainly taking his New Year's resolutions seriously!

The star of The Hangover was looking dramatically slimmer at last night's Screen Actors' Guild Awards in Los Angeles, so much so that he looked almost nothing like his former self – especially without his signature beard! Having skipped the red carpet, it was only during the ceremony that viewers noticed his weight loss.

The actor showed he hadn't lost his funny side though, playing up to the cameras during the ceremony's opening sequence. While other actors gushed about their craft and the dedication it takes to become a star, Zach turned to the camera and simply said, "I'm Zach Galifianakis… I'm an actor."

Thanks for clearing that one up, Zach!

The 45-year-old first showed off a noticeably slimmer figure back in October at the New York Film Festival, looking dapper in a grey suit:

Speaking about his choice to drop the pounds, Zach said his weight loss was mainly to do with cutting out alcohol. "I stopped drinking and I just kind of put the weight off…I was having a lot of vodka with sausage…delicious but bad for you,” he told Conan O'Brien last year. "I was getting into too much trouble with the drinking, so I just kind of stopped."

Well done, Zach!
