When it comes to dramatic Hollywood transformations, John Goodman is in a league of his own. The actor, best known for his role as Dan Conner on Roseanne, has lost 200 pounds since beginning his health journey in the late 2000s – and has been an outspoken advocate for building a better lifestyle through gradual, sustainable changes.
From his decision to make a change following struggles with alcoholism, to his staggering weight loss fueled by a fresh diet and over 10,000 steps a day, here’s the former West Wing star’s journey in photos and what he’s said about his drastic transformation.

After ruling our TV screens in the 90s, John went on to star in animated hits like The Emperor’s New Groove (2000) and Monsters, Inc. (2001).
The actor told ABC in 2017 that he’d tried to embark on a health journey previously, but explained that “in the old days, I would take three months out, lose 60 or 70 pounds, and then reward myself with a six-pack or whatever and just go back to my old habits.”

John has also spoken candidly about his struggles with alcoholism at the time, telling The Guardian he checked himself into a rehabilitation centre in 2007.
"It was getting to be too much," he said. "It was 30 years of a disease that was taking its toll on everyone around me and it had got to the point where, every time I did it, it was becoming more and more debilitating. It was life or death. It was time to stop."

“I’m breaking a sweat but I’m not going nuts,” he said, while his coach added that he was “very agile…he can be a different type of actor now. He can take on athletic parts.”

“This didn’t happen overnight — it’s been an ongoing process,” Mackie told the New York Post. The trainer also revealed John was taking 10,000 steps a day, working out six days a week, and following a “Mediterranean-style eating plan”, which prioritised fresh fish and nuts alongside fruit and vegetables.

John joined the cast of Kong: Skull Island in 2017, revealing to ABC News that his agile co-stars, like Brie Larson, helped fuel his lifestyle goals. “She’s so charismatic,” John said of Brie. “It kind of kicked up again why I’m doing this and it reminded me of what I was like when I was her age.”
The actor also revealed he’d wished he’d “appreciated” his time on Roseanne more, admitting that his alcohol struggles affected his enjoyment of the hit show. Fans were ecstatic when John joined the cast of the spin-off series The Conners in 2018, with viewers noticing how different the beloved character looked.

“I was boxing up until then and I haven’t been able to do that since Covid because I’m lazy,” the star confessed to Rolling Stone. “I’ve just let everything go just because I haven’t had the energy because of the jobs.”
