In a life-altering competition, contestants use medically approved weight-loss techniques to shed pounds and try to win a $250,000 prize. The twelve players are seperated into teams - red and blue - and in the first challenge, pulling a heavy car across a track - the Blue Team prospers, but despite their advantage, the Blue Team also loses the least amount of weight at the weigh-in, and Dana becomes the first to be voted out.

After a tough elimination, the Blue Team gets back into the game on the second challenge, a bake-off which will determine the winner of a luxorious spa visit. The catch is that if any player takes a taste of anything they bake, 50 percent of all profits their team made is not counted. At the end of the task, the Red Team pulled through, making $362, edging out the Blue Team's $245. More importantly, the player's will power held strong, and no one took a lick of any food. At an emotional weigh-in, where neither Maurice, Lizzeth, Dave or Matt lose any weight, the Red Team is sent to the elimination ceremony, where Lizzeth is sent packing.

The Red Team and the Blue Team are forced to go onstage and perform about their feelings on their weight and weight-loss. The winner, decided by the audience at the nightclub which the players performed at, is the Red Team, who is given a reward. Later, even with the Blue Team training as hard as ever, the Red Team loses more weight than the Blue Team, forcing Blue to the elimination ceremony, where rumours and whispers divide their team. The deciding vote comes down to one of the Blue Team members, and Aaron is eliminated.
