Everybody is losing weight this season. From governors to actors to singers, this season is all about being healthy. Now the latest personality to catch up on the trend is the Hangover's Zach Galifianakis. The star shocked the red carpet when he appeared on Sunday's red carpet premier in a lean frame that was quite different from the roly poly image we had seen on the Hangover.

Zach Galifianakis was the talk of the red carpet community when he appeared before the cameras looking more lean and fit than he has ever been. Galifianakis had appeared to promote his latest film Birdman (or The Unexpected Virtue of Ignorance).

On the red carpet, E! News Alicia Quarles couldn't resist asking the actor about his dramatic weight loss. The actor clearly has not lost his funny side. He quipped, "No, I'm just ... I'm dying."

The reporter went ahead to re assure the actor, telling him that he looked good. The actor wasn't at a loss of jokes. "Thank you, it's a ladies' [size] 50," he said.

Zach Galifianakis mentioned in a recent interview that the secret to his shocking weight loss was quitting the bottle. He told Conan O'Brien that he stopped drinking and the pounds just sort of disappeared. "I was having a lot of vodka with sausage," he joked. "Delicious, but bad for you."

Galifianakis has kept a low profile this year, not appearing on any premiers or in public. This Sunday, he got back on the red carpet and onto the spotlight as he promoted his latest movie.

As it appears, Zach loves the red carpet. He revealed his true feelings about the red carpet on Tonight show with Jimmy Fallon. I live for the carpet. Salt-of-the-earth people there," he joked. "There's excitement and you kind of have to feign this excitement. And then you have to answer questions that, I find, the questions are boring. So I try to liven it up a bit."
