The 16 new contestants introduced their trainers to their diets for a day, and then left for Camp Biggest Loser. At Camp, they were faced with their first weigh-in, but surprised by being joined by family and friends.
The Black Team won the Challenge. After White and Blue fell below the Yellow Line, the other contestants were given the option to send no-one home, but only Alex and Graham took this option, sending Selena home.
The contestants were faced with a temptation for $30,000 of the Winner's Prize Money. James took it, and was given the money in Gold bullion, handcuffed to his wrist until weigh-in, where he had to decide whether to take the money or stay at Camp with immunity.
In the Challenge, the Red Team beat the Black Team in the Final, giving them the 2 kg advantage. James decided to take the money and leave the competition. After White and Black fell below the Yellow Line, the other contestants sent Shane home.
Hayley revealed to the trainers the existence of The Bunker, a secret room where they could spy on their contestants. The Contestants were challenged to give a short speech to others who were struggling to lose weight about their struggles.
