Supermodel Heidi Klum appears nude in a block of ice for her friend Rankin’s “Less Is More” art show in Germany.
In the sizzling Dec. 14 Instagram photo, Heidi squats nude with her wet and slicked back.
Klum’s photo is one of 150 pieces in the Rankin art exhibit. The mom of four is incredibly fit thanks to a low-carb diet and regular workouts that include circuit-training, cardio and weightlifting, Examiner reported.
“I’m pretty good about not eating too many carbs,” said Klum. “I love vegetables. I don’t eat bagels—no way! A bagel is basically a cardboard box. Usually I’ll have a smoothie in the morning.”
Heidi avoids processed foods and makes sure her daily diet features fresh vegetables and home-cooked German meals, as Celebrity Health Fitness reported. “I like to stick to fresh fruits and vegetables and lean proteins,” she said.
Low-carb diets such as the Atkins and ketogenic diets fuel rapid weight loss by inducing the body to burn fat for fuel, said obesity expert Dr. Eric Westman, co-author of Keto Clarity.
Heidi also tries to work out every day combining circuit-training workouts, strength-training, lunges, step-ups and rows, as well as belly-targeting exercises to keep her abs flat.
Klum incorporates exercise into her daily life by hiking with her children, running on the treadmill for 30 minutes at home, and doing sit-ups and other calisthenics in her hotel room whenever she travels.
Heidi also works out with her longtime trainer, David Kirsch, author of The Ultimate New York Diet.
While most people dread getting older, Heidi is comfortable with aging and has no interest in getting plastic surgery.
“I don’t think of getting older as looking better or worse; it’s just different,” said Klum. “You change, and that’s OK. Life is about change.”
Heidi is the spokesmodel for her Heidi Klum Intimate lingerie line.
