The Biggest Loser is a British reality television show that began airing on Sky Living from 2005 to 2006, before moving to ITV in 2009 and finished in 2012.
[citation needed] The first two series of the show were hosted by Vicki Butler-Henderson on Living TV.
The show then moved to ITV, where the third series was hosted by Kate Garraway, and the fourth and fifth by Davina McCall.
[2] The basic format of the show is that overweight contestants compete to win a cash prize by losing the highest percentage of their starting body weight.
The third series switched to a new "couples" format, where eight pairs of friends, relatives or colleagues started together for the first 5 weeks, before splitting into a "black team", trained by Dowds, and a "blue team", trained by Richard Callender,[3] and started competing against each other, as in the first two series.
