Viewers tuning into the premiere of the 39th season of "The Price is Right" this morning saw themselves starring at a much-slimmer and healthier host Drew Carey.

The 52-year-old lost more than 80 pounds since January — and for those not glued to the tabloids in the meantime, the reveal of Carey's new look was unexpected.

"My first reaction when Drew came out from behind the door at the start of the show was 'wow, he looks ... odd,'" said TVSquad's Bob Sassone. "That's not a dig at Drew — he looks great — but it's just the shock of seeing someone who's looked a certain way for 20 years appear a lot thinner. Took me a moment to get my mind wrapped around it."

So how'd he do it? Naturally, with plenty of vegetables, exercise and low-fat meals.

"No carbs," Carey he told the NY Daily News earlier this July. "I have cheated a couple times, but basically no carbs, not even a cracker. No bread at all. No pizza, nothing. No corn, no beans, no starches of any kind. Egg whites in the morning or like, Greek yogurt, cut some fruit.

"I don't drink anything but water," he added. "No coffee, no tea, no soda."

Carey also worked out 45 minutes every day and went from a size 44 pants down to a 33-34. "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," he said.
