The Biggest Loser returns on a much larger scale! We have more contestants than we’ve ever had before, and everything they think they’ve prepared for will be turned inside out, and upside down in Season 4. Over 6 nights a week for 12 weeks, 20 ordinary Australians will be transformed into the people they always dreamed they could be - this is the only reality series in which everybody "loses".
The most significant change to the Biggest Loser in 2009 is the introduction of couples. This year we have 10 couples, 20 contestants in total, competing and being eliminated as a couple. The dynamics of the game completely change. We have mothers and daughters, husbands and wives, friends, brothers, sisters, work mates and in-laws. The added support of a loved one means increased confidence, fiercer competition, better results and much more game-playing.
