Marla Maples is 45 and doesn't look it whatsoever. She attributes her fit and radiant body to regular exercise and healthy eating. She says, "I have a lot of willpower," and sticks to a mostly vegetarian diet. Marla also avoids dairy products and coffee, and instead her beverages of choice are Ayurvedic teas that help with digestion. When it comes to splurging on not-so healthy foods, she says, "With things like pizza and pasta, you go to a restaurant and it's ever so tempting, but if I know it's not going to make me feel good after, I'm going to stay away from it." What great advice, but it's tough to have that kind of self-control. If you have any tips on how you stick to a healthy diet, share them in the comment section below.
