Singer Katy Perry [1] has an amazingly fit body to go along with her strong voice, but jumping on stage isn't the only way she stays in shape. The 30-year-old, who blew viewers away with her physically demanding Super Bowl halftime show [2], is all about eating right, exercising, and even meditating.

An immune-boosting diet: Katy is a fan of Harley Pasternak's Five Factor Diet [3]. It encourages you to eat five small nutritious meals a day and to exercise five times a week. She told People [4] that now she's all about light, brothy soups, grilled chicken, whole grains like quinoa, and grilled asparagus. She gets vitamins and nutrients from fresh-pressed juices and coconut water and focuses on eating a balanced diet to keep her energy levels high for performances and to avoid getting sick.

Smart swaps: Katy has a salt tooth, so when she's craving something like Mexican food, she finds a healthier version [5] such as quesadillas with turkey, black beans, and low-fat cheese. When she's craving nostalgic favorites like PB&J, the singer turns to specially concocted smoothies [6] that have all the right flavors without the fat.

How she stays fit: This pop singer prefers getting outside instead of hitting the gym and enjoys hiking, but she also makes time for workouts designed by trainer Harley and loves jumping rope. "Katy aims to exercise five days a week, doing short, high-intensity workouts, including lunges and hip thrusts," Harley says [7]. "These tone, as well as boost her metabolism, and can be done anywhere."
