The original Buffy the Vampire Slayer, Kristy Swanson, got back into fighting shape in time for her wedding to ice-skating legend Lloyd Eisler.

Swanson lost the weight by following the Medifast plan. On the Medifast website, Swanson says, "After the birth of my son, I was tired and not feeling good about myself. I knew that I had to make a change to drop the baby weight. I was so happy with my success, that my mother decided to try Medifast and she lost 20 pounds."

Exercise was also an important component in Swanson's weight loss success. She worked out on the treadmill, took martial arts classes and jumped rope.
