Louis Anderson, 67, has recently revealed that he lost around 40 lbs. – thanks to intermittent fasting, which he started following when the COVID-19 pandemic began.

The Coming to America actor said he has been working on his fitness over the last few months.

On Tuesday, Anderson joked to Conan O’Brien, “I started the pandemic at about 370 or 380 pounds depending on what I was leaning on. And now I’m 340. I’m trying to get 275 so I can get into some of my mom’s actual clothes.”

He went on to poke fun at his weight loss journey. He told O’Brien, “I’m on the intermittent fast. One minute I’m eating, the next minute I’m not. Then I’m eating again. I figure, that way, I’m only eating for 30 minutes out of 60, which is half. I’m trying to get down to 40/20 so I’m not eating for 40 and eating for 20.”

“No, it’s a wonderful thing, the intermittent fasting,” he added.

Anderson also said his weight loss would affect his approaches to comedy.

O’Brien asked, “You’ve spent a career telling really funny jokes about being heavy. You’re losing weight, you’re going to get down to this goal weight of 275 — are you going to retire those jokes?”

Anderson nodded and said, “Yes, I’m going to retire my fat jokes. I think I’ll always be funny.”

The Life with Louie actor said that it will be a major change for him. He said, “My first joke, I walked up on stage and I said, ‘I can’t stay long, I’m in between meals.’” The story was originally published on PEOPLE.
