In the end Ali Vincent won, making her the first female winner in the history of the American Biggest Loser series.
The second challenge separates the teams so that each member faces temptation on his or her own: four minutes alone, surrounded by thousands of calories in favorite foods.
At the weigh-in, Paul & Kelly (Yellow Team) were the "Biggest Losers of the Week" by posting a 23 lb (4.26%) weight-loss, only a fraction more than Brittany & Bernie.
Each contestant had to cross a large swimming pool on a balance beam and place 12 pegs (one at a time) into a board on the opposite side.
First aired January 29, 2008 At the physical challenge, the contestants are brought to a shopping mall to face a pair of two-story escalators, each going down.
After that, the order in which the players drop out (and the amount of time he or she lasts) is: Kelly (2:55), Jenn (3:11), Jackie (5:00), Roger (8:24), Maggie (10:04), Bernie (12:30), and Brittany (23:59).
The person who finds the star gets to choose one player from the opposing team and make their weight not count at the next weigh-in.
The contestants are given 15 minutes to shop for ingredients at Whole Foods Market, and must adapt Rocco's recipes to create calorie-controlled appetizers, entrées and desserts.
Bernie's 13-pound weight loss is "just icing on the cake," says Alison, and gives the team a final weight-loss of 47 lbs, or a percentage of 4.09%.
First aired February 12, 2008 The episode begins with Dan talking about how upset he is with his team, and how he feels betrayed because they lied to him and Jackie.
The Challenge turns out to be that two pairs from each team will have to hold up the amount of weight that they have lost using a pulley system over water.
Jillian states that the only fair way to pick who will get immunity on the Black Team is to place names in a hat, and to pull them out one by one.
After Paul returns home, he is afflicted with double pneumonia and, as a result, puts back on a few of the pounds he lost.
When he climbs the hill to get his prize, the envelopes which usually read "Luxury", "Family", or "Gameplay" each have a large question mark on the outside instead.
The obstacles include flipping 200-pound tires, moving a ton's worth of heavy sandbags, crawling on their bellies to push medicine balls, and a half-mile all-out foot race to the finish.
Had Bernie not granted his immunity to Brittany (-5), whose percentage of 3.35% was not included in the final determination, they would have swapped positions, with him above the yellow line and her below.
First aired March 11, 2008 The show opens with something of a surprise: Almost immediately after Bernie is eliminated for Week 10, the six remaining contestants are called back to the gym for yet another weigh-in.
At the Week 11 weigh-in, Alison reminds everyone of the rules: The two individuals whose weight-loss percentages fall below the yellow line will be up for elimination.
At Macy's, each of them receives an outfit, a $1,000 gift card and a new look, coordinated by guest star Tim Gunn of Bravo's Project Runway.
The players must walk backwards on their treadmills in a test of endurance, with both the incline and speed increasing at regular intervals.
At home, it is revealed that Brittany has fulfilled her dreams and faced her skydiving fears, and she has lost a total of 62 lbs.
The women surprise the men of the former Blue Team by coming in first and second at the weigh-in, while Dan and Mark each fall below the yellow line.
In the elimination room, however, Jay's choice is not revealed as Kelly, Ali and Roger all cast their votes for Dan.
In the Biggest Loser update, it is revealed that Dan moved to Los Angeles to pursue his music career with a newfound confidence from his weight loss.
For this week's challenge, the five remaining contestants competed in a triathlon, which includes swimming 300 meters across the Sydney Harbour, then riding on bicycles, and finally running across a park and climbing up a 44-story building to the top, where Alison is waiting for them.
They both got to ride on a sea plane, then eat an outdoor breakfast together with a breathtaking view of the ocean, and a phone call home.
Kelly lost one pound, Roger dropped two, and Ali won the weigh in again for the second time in a row, and the third overall, by posting a 3-pound weight loss.
Later, they show Jay at home, where he reached his weight loss goal of 100 lbs, and plans to run in a 10K event.
First aired April 8, 2008 When the final four return from Australia, they are greeted by celebrity chef Rocco Dispirito, who last appeared on the show back in Week 6.
Appearing on the episode included: Finalist Ali, and eliminated contestants Bette-Sue, Mark, Jay, Jackie, and Dan.
