Tracy, 37, is married with no children. Like Bonnie, she's not particularly unhappy with herself as a person, but she's frustrated by her inability to maintain a healthy weight and lifestyle.

Tracy also has high blood pressure, and this has become a major health concern as she faces her fortieth birthday.
