Russell Crowe is opening up about his weight loss journey.

During a Nov. 5 appearance on "The Joe Rogan Experience" podcast, Crowe, 61, revealed how much weight he lost since he finished shooting his war film "Nuremberg" a year ago.

He shared that he was 126 kilograms, or 277 pounds, when filming wrapped, and he's now 100.9 kilograms, or 222 pounds -- a difference of about 55 pounds.

Crowe credited his weight loss in part to injections and intravenous treatments he's received for knee and shoulder injuries he's had over the years.

"It's calmed down my body's inflammation," Crowe said on the podcast.

"It's calmed down a bunch of stuff and it's taken a bunch of pain away, so I can go and work out and not have to suffer for two or three hours afterwards," he added.

The "Beautiful Mind" actor also said in the interview he doesn't drink as much as he used to.

"I'm a big proponent for having a drink," he said. "It's my cultural heritage and as a working-class man, it's my goddamn right, Joe. But as you get older, there are certain things you start to learn about your capacities..."

"Now that I'm an older guy, I know that one night a week, if I'm having fun, is plenty. I try to cut out the interstitial stuff," he said.

Crowe explained that he'll sometimes have a "nice" glass of wine for dinner. As for casual drinks, he said that isn't his thing anymore.

"I try not to have casual drinks now, having a drink for the sake of it," he said.
