The Biggest Loser: No Excuses

"The Biggest Loser" returns with a bang for Season 13 when the contestants arrive at the ranch and get one of the biggest surprises ever in the series' history. They arrive in teams of two - including mother/daughter, father/son, brother/sister and husband/wife, all eager to change their lives together. But they're shocked to discover that they will not only be split up - they will also be competing against the person they came with. They'll be pushed out of their comfort zones in a way they have never been before - and one team won't even make it on to the ranch - as the season of "No Excuses" begins.

All of the contestants have the same goal: losing weight and getting healthy. But they all have different excuses for why they never lost the weight before, ranging from being too busy, not knowing how to eat right, being emotional eaters, knowing they could always start a weight-loss program "tomorrow" and more. So the season of "no partners" will also be a season of "no excuses" - as week in and week out, all the typical reasons for not getting in shape will be addressed.

The contestants will hit the ground running with a three-part challenge as soon as they arrive. While 18 of the 20 contestants come to the ranch with loved ones, two will initially be paired as strangers. Following the initial challenge, each of the pairs will be divided into two new competing groups of individual players who will be trained by either Bob Harper or Dolvett Quince, both fiercely competitive and determined to whip their contestants into shape, and deliver the season's $250,000 grand-prize winner.

Hosted by Alison Sweeney, "The Biggest Loser" will feature new contestants that include Nancy Rajala, who has 13 children and 55 grandchildren and didn't gain weight until she became a widow at 52, Kim Nielsen, a former professional wrestler and single mother of three whose career ended when she broke her back in a wrestling match, and Roy Pickler, a Santa Claus and scout leader who wants to get in shape so he can continue taking scout troops on adventures as he has for almost 25 years.

Also competing this season will be former Junior Olympic weight lifter Emily Joy, music producer Adrian Dortch, who has been a background vocalist for artists like Seal and David Foster, Ben Shuh, a father of nine children with a 10th on the way, and Cassandra Sturos, whose weight has held her back from pursuing her dream to move to New York to be a writer.

"The Biggest Loser" is a production of Reveille, 25/7 Productions and 3 Ball Productions. Ben Silverman, Dave Broome, JD Roth, Todd A. Nelson and Todd Lubin are the executive producers.
