As if being one of the highest-paid TV actresses isn't enough for people to envy, Kaley Cuoco-Sweeting has now stripped down to show off her killer body. While we may never have as successful of a show as Cuoco does, we can at least try our hardest to get her toned tummy because she shared all her diet and fitness secrets in Shape Magazine's latest issue.

While looking nearly flawless in just a plain white button-up, with nothing underneath, and a pair of white underwear, the 29-year-old "Big Bang Theory" actress has nothing but yoga to thank for the way she looks.

"Doing yoga five times a week has transformed by body," she revealed. "I love being toned and having muscle; it's so sexy and beautiful. And I owe it 100 percent to yoga." She went on to explain how she does a mix between hot yoga, sculpting yoga with weights, and even a little cardio mixed in, but it took a lot of hard work to get where she is today.

"I've never worked so hard to look good for something in my entire career," Cucoco, who admits to keeping drawers full of candy in her bedroom, said. "But I didn't starve or kill myself with exercise. I went slowly, and it paid off."

She's lost six pounds in the past three months, which she knows isn't some crazy amount, but it has made a huge difference in the way she feels, and it shows!

As for her diet, she and her husband, tennis player Ryan Sweeting, decided to cut back on their junk food intake.

"Our refrigerator and pantry have completely changed," she said. "Because we don't eat crap anymore. No more soda, chips, cereal; we had boxes of stuff that only a 4-year-old would eat."

But that doesn't mean she doesn't let herself indulge every once in a while. Every Sunday, she gives herself a cheat day and celebrates with a drink and some pizza before she starts her week off on a good note on Monday again.

She couldn't be happier with the lifestyle changes she's made, and has never felt this great in her life.

"Everything, from the inside out, has completely changed for me," she said. "And now, when I look into the mirror and see the positive changes, I don't want to go back to what I was doing. Especially when my husband is like, 'You look amazing!'"

As for the upcoming season of "The Big Bang Theory," Cuoco can't wait for everyone to see what goes on between she and her on-again-off-again TV boyfriend Leonard. "Between Leonard and Penny, all the dreams came true for me," she told Entertainment Weekly last month.
