"Extreme Weight Loss" is a unique undertaking that's unlike anything you've ever seen TV. The show documents the amazing makeover of seventeen courageous, obese individuals who set out to safely lose half of their body weight over the course of a year. The metamorphosis is truly amazing. Trainer/transformation specialist Chris Powell (The 650-Pound Virgin) guides each of the seventeen participants through the process after moving into their homes. He's there to make sure the participants get the proper nourishment and exercise movement. Chris provides a fresh perspective to individuals whose lives have become unmanageable because of their weight.
