The Biggest Loser challenges extremely overweight contestants to drop pounds and transform their lives. Every week, a weigh-in determines who stays and who goes home. Throughout the season, contestants live on a secluded ranch and abide by strict rules. All communication with their families and the outside world is cut off. With no access to television, radio or the Internet, the men and women focus on the fight of their lives.
For as many as seven hours a day, contestants hit the gym with television's toughest personal trainers, Bob Harper and Jillian Michaels. The women eat about 1,200 calories a day but burn up to 4,000 calories. The men limit themselves to 1,800 calories a day and work off an astounding 6,000.
As they're pushed to their physical and emotional limits, contestants begin to see dramatic results. At the end of the program, one person walks away with $250,000, the title of "The Biggest Loser" and a new outlook on life.
