The Biggest Loser UK is hosted by Kate Garraway. Contestants compete to loose the greater amount of weight and be crowned the series champion. The 16 hopefuls have to live together for 8 weeks where they set weekly challenges to help them loose weight and change their lifestyles. The second series was hosted by Davina McCall and instead of being shown daily it was shown weekly in a primetime slot.
Sarah Partridge, Kevin McLernon fand Amy McLernon battle it out to win the £25,000 and the title of The Biggest Loser 2012, whilst the runner-up will be awarded a luxury holiday.
