After 24 weeks of gruelling challenges and intense training, finalists Amy McLernon from South Shields, Sarah Partridge from Haverfordwest in Wales and Kevin McLernon from Sunderland will take to the scales to find out who has proved triumphant in the weight-loss reality series.
Meanwhile, all the other eliminated contestants will also be returning to showcase whether they have maintained their diets and fitness regimes after leaving the show.
Amy, Kevin and Sarah have spent eight weeks without family and friends and attempting to avoid temptation as they bid to lose the weight, which has caused them upset and health problems throughout their life.
The champion will win £25,000, while the runner-up will earn a week-long holiday to Antigua.
The Biggest Loser final airs tonight (March 12) at 9pm on ITV1.
