John Goodman's half the man he used to be -- and it's all because he stopped eating "crapola" every time he opened his mouth.

The "10 Cloverfield Lane" star opened up about his 100+ pound weight loss while promoting his new flick -- which he filmed right before he dropped the lbs -- on The Howard Stern Show this morning.

"I decided to stop stuffing food into my mouth every five minutes," the "Roseanne" alum explains, when asked how he pulled off the amazing transformation. "Turns out I was just eating all the time. Anytime I had my hands open or free, I shoved something in my mouth. It’s all crap."

The 63-year-old actor says he misses chowing down on "M&Ms" and other food he described as "crap," but was able to control his weight thanks to smaller meal portions and a steady exercise plan.

"It’s been a year and half, I did it slowly," Goodman explains. "I used to go on these diets, take three months and lose about 60-70 pounds, feel great, and reward myself with craopla. Twinkies look good."

He adds that he works on an elliptical at home and does stomach crunches on the regular.

That, coupled with his giving up drinking eight years ago, helped him get a much healthier way of living.

"I took it slow. I just wanted to change my lifestyle," he adds. "You look in the mirror everyday and go, 'I gotta deal with this the rest of the day, I gotta deal with this schmuck?'"

He's definitely happier with what he sees now!
