They went to nursing school together, had a double wedding, moved into a home together with their husbands and even started having children at the same time. Both sisters also had gastric bypass surgery but gained most of the weight back. As a nurse, Stephanie works long hours, so it’s often easier to ignore exercise and eat junk food than it is to maintain a healthy lifestyle.
