British comedian Ricky Gervais forces himself to go to the gym - so he doesn't have to give up eating "nice" food. The Office star, 46, takes regular visits to the gym but confesses it is only because he refuses to adopt a healthier diet. He says, "I had a slice of pizza after I worked out. I don't want to give up eating nice things, so I burn off the calories the next day, so I can do it again." And he admits he hasn't weighed himself for some time. He adds, "(It was) probably when I had the medical for the (U.K. TV show) Extras Christmas special. (My weight)'s been the same for about three years now."
