Matt Damon says he will box to shed the pounds he put on for film role!

USA Today:
For Matt Damon, this summer has been one of gains and losses.
He's preparing for the birth of his second daughter, helping launch a charity and hoping for some major reductions around his waistline.
Damon, 37, is working overtime to drop the 30 pounds he packed on to play a whistle-blower in Steven Soderbergh's 2009 drama The Informant. He has to shed the weight by early September to be svelte for re-shoots of the Paul Greengrass drama Green Zone, in which he plays a soldier looking for weapons of mass destruction in Iraq.
"If you put it on, it's easier to get it back off," he says.
His weight-loss strategy: "I'm just boxing. I figure if you get hit enough times, it will fall off."
