Read the excerpt from "Healthy Eating." "I was taking all these pills like an old woman," said Naar, a neonatology nurse at Baptist Hospital. "My blood pressure is hereditary, but I added to it by adding the pounds and eating horribly every day." . . .

Today, Naar is 20 pounds lighter and down to two pills a day.
