Marisa MillerMarisa Miller has a confession to make. "I'm very shy," says the 5'8" blonde stunner in a friendly voice that seems to contradict the statement. "I know it's weird for a person who models lingerie and swimsuits, but I don't like to be the center of attention!"

Too late for that. Soon after being discovered by famed photographer Mario Testino on a California beach in 2001, she landed a coveted spot in the Sports Illustrated Swimsuit issue, which led to a Victoria's Secret contract and numerous endorsement deals. Now the 33-year-old is in Boston filming her first movie, R.I.P.D., with Jeff Bridges and Ryan Reynolds.

Making the switch to acting was a major leap--professionally and personally. "Eighty percent of the things I do are not natural for my personality. I believe you have to fake it till you make it. Act like you're confident and you'll get there," says Marisa, who lives in L.A. with her husband of five years, music producer Griffin Guess. There are more words of wisdom where that came from. Check out Marisa's plan for getting everything you want--starting now!

Diet Tricks That Really Work

Marisa's stay-slim strategies are anything but garden-variety.

Eat Naked

Sounds kooky, but she has a point: "Eating smart is all about having an awareness of your body. The most obvious way to do that is by seeing it. So when you're trying to lose weight, spend more time wearing less. I don't think I could eat a plate of nachos naked--could you?"

Prep Ahead of Time

"I'll cook a batch of brown rice or quinoa and keep it in the fridge, so when I get hungry, I can easily dress it up with olive oil, lemon, and salt and pepper, and then add veggies," says Marisa, who often has zucchini and spinach.

Practice Portion Control

"I usually say no to the bad things at Whole Foods, but then I get to the register, where they have individually wrapped chocolates. I'll grab five and keep them at home. If I need something sweet, I've got it!" she says.

Make Smart Swaps

Marisa has found healthier alternatives to fattening foods. Instead of potato chips, she munches on organic Rhythm Superfoods Kool Ranch Kale Chips. And she mixes tuna with Wildwood garlic aioli instead of mayo. She also whips up leaner versions of Griffin's high-fat favorites--such as a BLT made with an Ezekiel English muffin, organic tomatoes, avocado, lettuce, and turkey bacon.

Keep Your Hands Off His Junk Food

"When I first met Griffin, I gained 10 pounds! When you are falling in love, all you do is make out and eat!" says Marisa. Now she has learned to indulge judiciously. "When I do have one of his favorites, like soda or cake, I look at it as a treat and enjoy it. Because I eat well 90 percent of the time, I don't feel guilty."
