We're all familiar with the public persona Gwyneth Paltrow puts forward -- stunning actress, wife and supermom, not to mention budding fitness diva. But there's a reason she practices such healthy habits -- her health. Recently, Paltrow admitted to seeking out three doctors to help her with "some very sticky health problems, including pneumonia, anemia and stress. And she admits, "they've helped me tremendously." Now she's offering some healthy advice of her own.

"Sleep eight hours for two weeks, then start eliminating 'white' foods," says Paltrow. "After two weeks of sleeping and eating better, you'll have the energy to exercise." Adds Alejandro Junger, an NYC cardiologist, "If you are totally out of shape, start by walking 15 minutes a day and add a minute every day for the first month. At the end of a month, you'll be up to 45 minutes a day, which should make you ready for whatever more strenuous form of exercise you want to try. Experiment with them all to see what works best for you and stick with it."

Will this help you look as good as Gwynnie? Unfortunately, no. She works out three hours a day. But hey -- it's a start.
