Melissa Joan Hart's Post-Baby Body

Working with a nutritionist, Melissa, who's also hitting the gym three times a week, has set some diet rules for herself to follow. "I have certain rules for myself, so no refined sugars," she says. "I try to stay away from white starches -- not carbs, necessarily, because I’ll eat pitas and corn tortillas, that kind of thing. But I try to avoid regular breads and pastas."
