"The Biggest Loser," known for its incredible weight loss makeovers, will reveal an exciting makeover of its own when the popular series returns this season with new host Bob Harper, a new "Temptation" theme, an updated state-of-the-art gym, a new logo, fun format changes and a return to the popular team vs. team competition. Dolvett Quince and Jen Widerstrom return to train eight contestant teams of two, all with compelling stories. Seven teams (spouses, parent/adult child, siblings, relatives, best friends) will know each other, but one team will be two strangers - former "Celebrity Apprentice" contestant and the original "Survivor" winner, Richard Hatch, and "The Voice" season two semi-finalist Erin Willett.

With only two weeks left on the ranch, Bob welcomes the contestants at a challenge that will tempt the winner with a prize that could change the course of the entire competition. Not only will they win a one-pound advantage for themselves, they'll gain the ultimate power in the game with the ability to give a one-pound disadvantage to one of their remaining opponents.

This week the contestants must face their biggest temptation of all - food. Host Bob Harper meets them at a food court where they must rely on their newfound nutrition knowledge to win a trivia challenge about unhealthy food. The winning team gets to choose a player from the opposing team to sit out at the weigh in. Then the contestants meet Dr. Huizenga at a medical research facility for a sobering look at how the food choices people make can mean the difference between life and death.

Host Bob Harper hosts an auction to win some flashy and functional prizes. One lucky contestant gets a one-on-one workout with Harper himself. Coaches Jen Widerstrom and Dolvett Quince are challenged during the workouts as some of their teammates are out enjoying the luxuries they won during the temptation challenge. During the last chance challenge the teams battle out a difficult physical activity to win the one-pound advantage for the weigh in.

It's one of the most eagerly anticipated events of 'The Biggest Loser' season - the fan-favorite makeover episode! Fashion expert Tim Gunn and celebrity hair stylist Ken Paves return to create amazing and inspirational transformations with the remaining seven contestants. And though they still have to stick to their weight-loss routines, there will be no temptation this week. After getting a brand new look from head to toe, the players get to show off their new slimmer selves to loved ones flown in to celebrate their big day. Later, they learn they're competing in a Last Chance Challenge with one of their loved ones for an advantage at this week's weigh in.

The winner of the opening challenge chooses a contestant from Team Jen and Team Dolvett to go home for the week. The only weights that matter in the final weigh-in are those of the contestants sent home, surrounded by old habits and temptations. Host Bob Harper makes a surprise visit to give a killer workout while the other trainers push their teams to the limit back on the ranch.
