"Extreme Makeover: Weight Loss Edition" will document the amazing makeover of eight courageous, "super obese" people. Shot over an unprecedented 365 days, the participants set out to safely lose half of their body weight, ultimately revealing an amazing metamorphosis. The term "super obese" defines those who exceed their estimated ideal weight by approximately 225 percent and who are roughly 200 pounds or more overweight. Trainer and transformation specialist Chris Powell ("The 640-Pound Virgin") will guide each of eight participants through their transformation process by moving into their homes with their families or loved ones. By assuring that they have the proper nourishment and exercise movement, Chris will provide a fresh perspective to individuals whose lives have become unmanageable because of their weight. In each of the eight one-hour episodes, the participants undergo a transformation not only of their bodies, but of who they are as individuals. Each stand-alone episode of the series will chronicle one participant's journey to reclaim his or her life.
