"I lost 20 [or] 22 lbs.," Gervais told PEOPLE Saturday night in New York at Night of Too Many Stars: An Overbooked Concert for Autism." "It wasn't so much about the weight. It was more that I was a fat, lazy, out of shape slob, to be honest."
So, how'd he do it? Running around his London neighborhood rather than diving into late-night meals. "I stick to the paths," he says of Heath jogs, adding, "I didn't eat differently. I probably just stopped having that second meal at 11:30 at night."
Jane Fallon, Gervais's partner of more than 25 years, believes that she, too, had a role in his weight loss. "I think it is because I was trying to lose weight as well," she said. "So I was cooking healthier version of what we were eating. He didn't realize that I was probably feeding him less calories at the same time he was running."
The cooking of "healthy versions of big fat things" really paid off for the couple. "I lost about 18 lbs.," Fallon said. "I tend to run about three or four miles and he does the same. "
One drawback? "Now I've got to stop making jokes about fat people, which is annoying," Gervais said. "When I was fat, it was okay."
