Bidding Wars
The Biggest Loser - S4 - E4
Another food temptation this week puts the trainers to the test instead of the contestants. Should Bob, Kim or Jillian give in to the temptation, it will give their team a 15-second advantage in the physical challenge. The challenge consists of the contestants running up and down a hill to reach their team flag in the fastest time. However, there is one catch: the teams will have to outbid each other with a faster time in hopes that someone will wager lower and lose, which will end up knocking out a team.

The contestants start off their weight-loss journey by being dropped off in the middle of the desert, while their trainers standby about a mile away from them.

However, this means the six remaining contestants have to be sent home, but Jillian Michaels returns to let them in on a little secret.

When the teams are put in a room full of tempting, unhealthy foods, they will have to decide in four minutes if it is worth it or not to eat the most calories in order to win a three-pound pass which can be used to their advantage at the weigh-in.
