"Hangover" star Zach Galifianakis is known for his raucous, deadpan sense of humor — and for being somewhat on the roly-poly side. But as he revealed recently, one of those things is no longer true.

Galifianakis is still as funny as ever, but stunned everyone with his newly reduced form at the New York Film Festival (he was on the red carpet there to promote his upcoming film "Birdman") and on Monday night's "Tonight Show Starring Jimmy Fallon," where he and the host had a very hard time scheduling a date to hang out.

Zach Galifianakis kept the beard but lost a lot of the weight between May 2013, left, and today.Today

The actor had already shed some weight when he went on "Conan" last year, quipping, "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."

But in his NYFF appearance, he said he's not done getting trim. On the red carpet, E! said he joked, "I'm dying" when asked about the weight loss, then noted that his suit jacket was "ladies' [size] 50."

The 45-year-old actor has been laying low for much of 2014, but returns as an exasperated lawyer in the upcoming Michael Keaton film "Birdman (or "The Unexpected Virtue of Ignorance)", which opens Jan. 2.
