Good for Goodman! John Goodman is showing off a slimmer frame these days — thanks to hard work and fitness guru Mackie Shilstone. The trainer has revealed how he helped the Roseanne alum lose over 100 pounds.

"This didn’t happen overnight — it’s been an ongoing process," Shilstone said, via the New York Post on Tuesday, Nov. 10. "There needs to be strategic planning. This time, he really wanted to do it."

And it shows! The Kong: Skull Island actor, 63, debuted his shocking weight loss at the BFI London Film Festival on Oct. 8. He wore a fitted navy suit and walked the red carpet with his Trumbo costars Bryan Cranston and Helen Mirren.

Goodman's slim-down was no easy feat, however. According to Shilstone, his transformation began when he first stopped drinking back in 2007. Goodman also changed up his diet and stuck to a "Mediterranean-style eating plan."

For Goodman, exercise was also key. The Argo star broke a sweat six days a week and tried to take at least 10,000 to 12,000 steps a day. When not at work, he saw results by working out on a treadmill and elliptical bicycle. 

As previously reported, Goodman's most famous on-screen spouse has also drastically changed her appearance recently. Last year, Roseanne Barr, 63, turned heads when she showed off her tinier figure at the NBC Universal Summer Press Day. "You eat less and move more," she told the Today show in June 2014.
