John Goodman lost 200 pounds. The actor, who once weighed more than 400 pounds, revealed in a new interview that his transformation came through years of disciplined eating and daily exercise, not a quick fix.

Goodman, 73, told E! News the weight loss happened gradually over roughly a decade. He said he cut back on sugar, stopped drinking alcohol, and began walking regularly before adding more intense workouts.

"I just got tired of being the fat guy," Goodman said. "I wanted to be around for my family."

The actor, best known for his roles in "Roseanne," "The Big Lebowski," and "The Conners," said his wife, Anna Beth, pushed him to take his health seriously. He credited her with keeping him accountable when he wanted to quit.

Goodman said he eats smaller portions now and avoids late-night snacking. He works out with a trainer several times a week and walks his dogs every morning. He does not follow a specific branded diet plan.

His weight loss became noticeable to fans around 2015, when he appeared noticeably thinner at public events. He has kept the weight off since then, a fact he said surprises even him.

"I've lost it before and gained it back," he said. "This time feels different because I changed how I live, not just what I eat."

Goodman has spoken about his health struggles in the past. He has dealt with sleep apnea and knee problems tied to his weight, conditions that improved after the loss.

Medical experts say sustained weight loss of that magnitude is rare. Most people who lose large amounts of weight regain a significant portion within five years, according to the National Institutes of Health.

Goodman said he does not weigh himself often. He goes by how his clothes fit and how he feels climbing stairs.

The actor continues to work steadily. He appears in the upcoming film "The Smurfs Movie" and remains a fixture on television. He said his energy level on set is higher than it was a decade ago.

Goodman said he has no plans to write a diet book or launch a fitness brand. He called his approach "boring" and said it works because he sticks with it.

His advice to others: start small, stay consistent, and do not expect overnight results. "It took me ten years," he said. "Nobody wants to hear that, but it's the truth."
