Zach Galifianakis – 56 lbs

If Zach Galifianakis looks familiar from somewhere, chances are you have seen the Hangover films or any of the 70+ other projects he has appeared in. He played Alan in the Hangover movies and somehow lived up to have no hangovers after that.

What we mean is that Galifianakis gave up the habit of drinking alcohol, which has not only helped his weight but done a lot of good to his internal organs. As per the Life and Style magazine, just the sacrifice of alcohol alone allowed him to lose 50 pounds. His self-control is inspiring, isn’t it? The 51-year-old continues to host Between Two Ferns with Zach Galifianakis.
