John Goodman was on The Late Show with David Letterman, talking about his weight - Dave's response to the noticeably thinner Goodman, "You look wonderful!"
When asked what his all-time weight high was, Goodman responded,
Plenty... pushing 400.. Somewhere up around there."
Here's his explanation of losing and gaining year after year.
I'd get off of 'Roseanne' every spring. I'd lose 60 lbs every spring. Then I got too fond of the barley corn... I'd gain it back and then some, every year."
Keeping his exact fitness regimen a secret, he did attribute his weight loss to a lot of exercise.
[I'm] getting a lot of exercise, I feel great.. It's going to be an ongoing process for the rest of my life."
