"I think I lost my Sexiest Man Alive title," the actor joked to People Wednesday at the Ante Up For Africa poker event in Las Vegas.
But that's not water weight. Damon estimates that he has gained between 25 and 30 pounds in preparation for his upcoming movie thriller, "The Informant", directed by Steven Soderbergh.
"It wasn't necessarily that I needed to be fat," he said. "It was that I needed to be 'doughy.' "
The movie tells the story of when the U.S. government goes after an agriculture business tycoon with a price-fixing accusation based on the evidence submitted by their star witness - Vice President turned informant Mark Whitacre (Damon). The film is scheduled for release March 7, 2009.
Even though the weight-gain was required for a role, that doesn't stop Damon's friends from mocking him mercilessly.
"Some things are just self-evident and don't even require making fun of," his best friend Ben Affleck said. "I mean the man buys two seats on an airplane!"
So how did he manage to gain so much weight?
"I just stopped working out and basically just ate whatever I wanted," he said. "I ate a lot of In-N-Out, a lot of burgers, a lot of beer and basically had a great time ... When you're in your 20s you can do that kind of stuff. When you're in your 30s, its a whole different ballgame."
A much slimmer Matt Damon can be seen next year in the drama "Margaret" starring alongside Anna Paquin, and the war drama "Green Zone" with Greg Kinnear, a thriller about a pair of CIA agents who are on the trail of certain Weapons of Mass Destruction and a foreign correspondent who is following their mission.
