As the realities of a sequestered life on the ranch set in for the 13 remaining contestants, they are tempted by an opportunity to receive comfort and a touch of home. Presented with a room full of their favorite food items, the contestants learn the only way to read a letter from their loved ones back home is to eat from the array of high-calorie treats. Just like their new eating style, the two teams' physical challenge requires balance to cross a balance beam suspended over water.

The battle of the sexes continues as the 12 remaining contestants must overcome injuries and trainer disputes. Another food temptation tests their resolve; they have to decide if they want "the gravy train" or the next physical challenge, which requires the teams to travel up and down the aisle of a moving railroad train.

The teams hit the road for the ultimate temptation town: Las Vegas, where the trainers teach skills for a hotel stay ranging from eating right when confronted with a buffet, to finding ways to workout within their hotel rooms. A card game that offers the chance to win up to $5,000 comes with high stakes - losing their trainer for the rest of the week. The team challenge for the opportunity to choose who sits out at the next weigh-in and to win a return trip to Vegas with their families consists of a relay race in the hotel swimming pool.
