The biggest winner is "The Biggest Loser" in this compelling new weight-loss reality series in which two celebrity fitness trainers, Bob Harper and Jillian Michaels, join with top health experts to help 12 overweight contestants transform their bodies, health and ultimately, their lives.

Caroline Rhea ("Sabrina, The Teenage Witch") hosts the unscripted, one-hour series in which two competing teams follow comprehensive diet and exercise plans to undergo radical physical makeovers.
Divided into two teams, Red and Blue, each team is given their own personal trainer. Unique physical challenges, surprising alliances and irresistible temptations make the competition even tougher for the contestants, who ultimately have to decide which player gets eliminated each week.
When only 6 contestants remain, the competition becomes individual. The players are now competing for themselves to stay in the game. The two contestants who have lost the least percentage of weight are eligible to be voted off.
In the end, "The Biggest Loser" becomes the biggest winner, walking away with a healthier body - and $250,000.
The series has become a worldwide hit airing in over 90 countries and produced in 25 countries. It has produced a New York Times best-selling book series with four titles currently and a fifth book slated to hit stands in March 2008. The show also has two #1 selling fitness DVDs as well as a burgeoning online lifestyle club www.thebiggestloserclub.com.
