Biggest Loser US

With obesity now one of the leading causes of preventable death in the United States, The Biggest Loser wanted to broaden their reach this season, pay it forward and motivate communities - not just contestants - to get healthy.

It's a week of surprises for the contestants, starting with news from host Alison Sweeney that the competition is getting bigger with the addition of two new players who didn't make it to the ranch in the premiere but have been saved by trainers Bob Harper and Jillian Michaels.

ne contestant expresses a wish to go home this week, creating drama and tension in the house, while another group of players form a secret alliance. Trainer Bob Harper puts the contestants through a grueling workout, zeroing in on one player he thinks has shown him disrespect, and later, trainer Jillian Michaels tries to bring out the athlete in two contestants she thinks need extra attention.

After hearing from host Alison Sweeney that two people will be going home this week, the contestants face their first temptation in the form of cupcakes, one of which represents a potentially huge prize for the winner that could grow more valuable each week.

Five contestants who didn't make it to the ranch in the premiere episode now return, all vying for a spot back in the competition. Whoever has the highest percentage of weight loss wins their way back in, and also wins one of the most important, game-changing decisions of the season when the competition moves to blue team vs. black team this week.

The contestants start their week hearing surprising news from host Alison Sweeney that at this week's weigh-in, only one person's weight will count for the blue team and the black team. It will be up to the opposing team to decide whose weight will count and the two contestants chosen won't be revealed until the weigh-in.

It's the adventure of a lifetime when "The Biggest Loser" contestants are whisked away on military trucks to Camp Pendleton, where they will live and train like Marines for the week. There, they hit the ground running with a fast-paced week of activities led by a select group of Marines.

Host Alison Sweeney greets players with the news that the black and blue teams are being dissolved, and instead, they'll be competing as pairs this week. A high-calorie dinner temptation will determine who gets to choose the pairs, and the winning contestant's choices for teams creates tension in the house and alienates at least one player who feels betrayed.

This week, the competition moves to singles, so contestants will compete on their own without partners or teammates from this point forward. The most recent elimination is still a big topic of conversation, with trainer Bob Harper trying to determine why the vote went the way it did and one player still upset over the departure of a close friend.

It's one of the most eagerly anticipated events every season - "The Biggest Loser" makeover episode! First, the remaining seven players head to the salon of celebrity hairstylist Ken Paves, who crafts great new looks for each of them, and then they're off to a People Magazine photo shoot.

The stakes are higher than ever this week when host Alison Sweeney informs the last six contestants that there will be a red line and a yellow line at the weigh-in this week, and those who stay above both will be in the final four.

The final four contestants leave the ranch and transition back to life at home, showing off their new slimmer selves tofamily and friends and facing the temptations and challenges of everyday life.
