Is President Obama losing weight from the stress of running the country?

A photo taken over the weekend shows a strikingly thin Obama leaving the gym at Fort McNair in Washington, D.C.

"Barack N' Bones" screams the headline on the Drudge Report. The website also quotes a source as saying, "No, he's not chain smoking. He's working non-stop for the country," and "Yes, he does occasionally skip meals."

Others say the President's apparent weight loss is due to a rigorous workout regime that includes intense basketball games with his buddies.

And the President addressed his weight last week at a Democratic Party rally in Miami: "I've tried to explain...just because I'm skinny doesn't mean I'm not tough!"
