The Biggest Loser: Couples is the fifth season of the NBC reality television series The Biggest Loser. The fifth season premiered on January 1, 2008 with ten overweight couples competing for a cash prize of $250,000. This season featured Alison Sweeney as the host, with trainers Bob Harper and Jillian Michaels; all three returning from season four.
