But over the last 10 years, he has steadily begun to shift the pounds and he has taken on a much healthier lifestyle.

Gradual exercise made a huge difference...

Speaking to TMZ back in March, he revealed that his secret to shifting the weight was simply through cycling everywhere.

The weight loss has been noticeable...

But his most recent transformation is jaw-dropping.

It turns out that the actor has been hitting the gym recently... a lot.

Despite his gradual weight loss, fans have been left shook after seeing some pictures of the newly hench Ethan Suplee.

New year, new me...?

It seems that Suplee has bulked way out...

And the reason for his bulking was because of an acting role back in 2017.

He was initially deemed as "too thin"...

His weight loss nearly cost him his role in Chance, which he worked alongside Hugh Laurie, as he told Entertainment Weekly back in 2017. "Initially, the casting directors didn't want me to come in because I'd lost a bunch of weight. Apparently they had proposed me a bunch of times, but the casting directors were like, 'No, he's too thin now.'"

This comment spurred Suplee to bulk since then...

He added, "I'd gained a bunch of weight back because I actually didn't find being thin all that it's cracked up to be. So we convinced them that I was heavier again, and I went in, and that was that. I was heavy enough."

He went on to explain his cycling obsession...

"After My Name Is Earl, I started obsessively riding bicycles. I actually did get properly thin at one point - I was nine percent body fat. But I was also riding a bicycle six to eight hours a day, six days. After two years of that, my wife said, 'Hey, idiot, you can't retire and ride bicycles. You have to go get a job,'" he said.

The industry no longer recognized him...

"So then [when I started looking for work], I found that people were like, 'Who are you? We don't know you. You're this new person.' So a couple of years ago I made the decision: I'm not going to kill myself to be thin when nobody knows me as a thin person, and I do think it is affecting the kind of jobs I'm getting," he explained.

But we must say...

He is looking pretty great. For some more incredible transformations, keep scrolling to learn about how Australian actress Rebel Wilson became unrecognizable after a huge weight loss...
