No More Fat Jokes for Slimmed-Down Ricky GervaisFunnyman Ricky Gervais lost a bunch of weight, putting fat jokes off-limits.

"Now I've got to stop making jokes about fat people, which is annoying. When I was fat, it was okay," the creator of 'The Office' tells PEOPLE.

Gervais, 49, lost "20 or 22 pounds," he says. "It wasn't so much about the weight. It was more that I was a fat, lazy, out of shape slob, to be honest."

The star's partner of more than 25 years, Jane Fallon, also 49, tells PEOPLE she's lost nearly as much weight, estimating 18 pounds. "I tend to run about three or four miles and he does the same," says Fallon.

"I stick to the paths," Gervais says of his jogs. "I didn't eat differently. I probably just stopped having that second meal at 11:30 at night."
