When a mega-celeb like Katie Holmes appears thinner than usual, it's easy to assume that it's because of her overbearing husband, her bizarre Scientology religion or her apparent desire to look exactly like Victoria Beckham. But according to the star herself, her recent weight loss is for much less interesting reasons -- she's simply working too much.

Working long hours six days a week during the recent Broadway run of All My Sons, Katie said her busy schedule was the reason for her figure. "My metabolism was in full gear the whole time," she says. "I lose weight fast when I'm working so hard. It doesn't matter how much I eat, I just get thin. It's not the worst problem in the world to have though is it?"

Fair enough -- I know when I'm busy at work, I tend to eat less too. Your thoughts?
