Miranda Kerr strips down totally naked in the new issue of Harper's Bazaar (save for a few pairs of hot thigh high boots) and the 29-year-old model Aussie stunner looks absolutely amazing. And can you believe she gave birth to baby Flynn a year and a half ago?!

While the mag's cover girl Gwen Stefani reveals that she "torture[s]" herself to stay fit, Miranda says that her secret to staying slender is all about moderation.

"Rather than diet my family instilled in me a real appreciation and passion for good health and organic living. I adopt the 80/20 rule. 80% good, 20% indulgent and that works for me and my body personally," she says. "I love food and enjoy eating fresh organic produce. I drink warm water and lemon every morning and I also drink lots of good quality purified and preferably alkaline water throughout the day. My Nan introduced me to Noni juice when I was twelve years old, which I drink twice daily. I treat myself occasionally and don't have any guilt or conditions placed on it. Food is my friend and consistency is the key. I believe that everything in moderation is best."

But what about workouts? Given how taut and toned she looks here, she has to be sweating it out at the gym every day, right? Not necessarily! “Yoga is at the core of my health and wellness routine, even if it’s only for 10 to 15 minutes I find it helps me to re-center and to focus as well as improve my overall core strength," Miranda explains. "Then I’ll do a few extra squats for my butt and thighs.”
