Marissa Jaret Winokur Weight Loss: Actress Shows Off 60 Pound Weight Loss (PHOTOS)

Actress Marissa Jaret Winokur boasts one of the most impressive celebrity weight loss stories of the year.

The 39-year-old Tony-winner has lost 60 pounds since March, and she recently told US Weekly, that she made the decision to shed the weight when her cholesterol levels became worrisome.

"I thought I'd try to lose 20 pounds and see what happened. It was the little steps. I think it worked because I was genuinely doing it for myself," she told the magazine.

Though she's already down seven dress sizes, she's looking to lose five more pounds "just for vanity." The former "Hairspray" star revealed she was ecstatic during a recent shopping trip when a salesman brought her out a size 2 dress.

"He eyeballed me and thought I'd fit in that!" she said.

The last time we spotted Winokur, she was just showing off her new slim figure at the premiere of "Wreck-It Ralph" on Oct. 31, and it looks like she's kept up her hard work.
