"I'm not a big eater," he said, according to The Sun. "I don't enjoy it that much. I'd rather have a beer than eat, any day of the week."

"Sometimes when we are going out for dinner because I know I'm going to hate the food, I have baked beans on toast before I go, then eat nothing."

John Goodman

"Roseanne" alum John Goodman has slimmed down, dropping 200 pounds in recent years.

Despite the extreme weight loss, Goodman admitted it wasn’t easy to keep off the pounds and at times returned to his unhealthy routines.

"In the old days, I would take three months out, lose 60 or 70 pounds, and then reward myself with a six-pack or whatever and just go back to my old habits," he explained in 2017, according to ABC. 

"This time, I wanted to do it slowly. Move, exercise. I’m getting to the age where I can’t afford to sit still anymore."

Drew Carey 

"The Price is Right" host Drew Carey said he was tired of being overweight. 

In 2010, Carey dropped a whopping 80 pounds, according to CBS. "It sucks being fat, you know," Carey expressed.

The now 64-year-old comedian is proud that he went down a couple of pant sizes and no longer has type-2 diabetes.

Carey got candid about his diet and fitness routine. 

"No carbs," Carey said. "I have cheated a couple times, but basically no carbs, not even a cracker."

He continued to say that his workouts consist of at least 45 minutes of cardio. 

"I like being skinny," said Carey, according to the media outlet. "I was sick of being fat on camera. Really, I just got sick of it. Once I started losing weight, again, like once I started dropping a couple pant sizes, then it was easy ’cause once you see the results, then you don’t wanna stop."

Kevin Smith 

"Clerks" director Kevin Smith was nearly unrecognizable after his extreme weight loss. 

In 2018, after suffering a near-fatal heart attack, the filmmaker revealed he lost 20 pounds in 13 days.
