The Biggest Loser (season 4)
The Biggest Loser (season 4) is the fourth season of the NBC reality television series entitled The Biggest Loser. The fourth season premiered on September 11, 2007 with 18 overweight contestants in a weight loss competition for an ultimate prize of $250,000. The Biggest Loser campus was located at California State University Channel Islands in Camarillo, California. The season four contestants were divided into 3 teams: the Red team, led by trainer Kim Lyons; the Blue team, led by trainer Bob Harper; and the Black team, led by trainer Jillian Michaels. The teams were formed on the first episode, with the Red and Blue teams being selected by the two players who had won a foot race across the desert. The Black team was formed with the 6 remaining contestants who were not selected for the Red and Blue teams. While the Red and Blue teams returned to the Biggest Loser campus, the Black team was left behind, believing that they had been eliminated already. Instead, they remained in the desert and trained in secret with their trainer, Jillian, until they arrived on campus for the weigh-in at the end of week 2. Teams
Each week, the team that has lost the lowest percentage of their total weight must eliminate one member. On the losing team, the team member who has lost the highest percentage of weight that week is immune and cannot be voted out. In the seventh week, the teams were dissolved and split into trios. Jez won a temptation and the right to decide the trios:

 Jez, Neil  and Isabeau;
 Hollie, David and Kae;
 Bill, Julie and Amy;
 Nicole, Ryan and Bryan

The individual players, regardless of which trio they belonged to, were allowed the option of continuing to work with their original trainer or switching to another trainer. Only Amy, who felt betrayed by Kim's negative comments prior to the previous week's elimination, opted to change trainers, choosing to train with Jillian. That same week, Neil, a contestant on the original blue team, ignited controversy when he threw the weigh-in by water loading, which resulted in a weight gain of 17 pounds. He did this in an effort to forcibly eliminate a black team member, and it resulted in Jez's elimination. The following week, he lost 33 pounds. This made him the greatest gainer in one week and the second greatest loser in another week at that time, occurring in back-to-back weeks. Although they trained separately, the trios competed together in challenges and at the weigh-ins. The trio with the lowest combined percentage of weight loss is considered to have fallen below the yellow line, and its members are up for elimination. The remaining trios each receive one vote during the elimination. In the event of a tie, the trio member with the lowest percentage of weight loss is eliminated. During the ninth week, the trios were dissolved and the players split into pairs for Green Week. The pairs were: Kae and Amy; Hollie and Bryan; Nicole and Neil; Isabeau and Ryan; Bill and Julie. The contestants competed in their pairs at the challenges and at the weigh-ins. One member of the pair with the lowest percentage of weight loss was eliminated. During the 10th week, the pairs were dissolved and the players were all competing as individuals. Although there was technically no longer a red, blue, or black team, the players still continued to work out with their original trainers and team, except for Amy who worked with the black team and even wore black colors instead of her original red. In the 12th week, Bryan, the last remaining member of the red team, was eliminated, which meant that Kim's entire team was completely wiped out, and thus she was eliminated as well. This marks the first time that an entire team, along with a trainer, has been eliminated before the final weigh-in. In the 14th and final week, Neil, the last remaining member of the blue team, was eliminated, which meant that trainer Bob has also been completely wiped out, and thus he too was also eliminated from the competition, leaving Jillian and her team to win it all. When he was eliminated, Isabeau reminded everyone about what Neil did to Jez seven weeks earlier. The black team wanted revenge against Neil after he sabotaged them, but could not get it because he constantly lost enough weight to keep himself above the yellow line; that is, until the final week of the on-campus competition, when he finally fell below the yellow line despite losing 10 pounds.

Week 1
18 contestants race through the desert. The first one to reach Bob and Kim become the captains of the Blue and Red team respectively. Jerry reaches Bob first and Phil reaches Kim first, and they earn the right to select five other contestants to fill out their teams. Kae, Neil, Patty, Nicole, and Ryan were selected for the Blue team while Bryan, Amber, Amy, David, and Lezlye were selected to the Red team. After not being picked, Julie, Jim, Jez, Isabeau, Hollie and Bill are met by Jillian, who informs them they are not going home, but forming the Black team, and will train in secret for two weeks before rejoining the competition on the ranch. The players on the ranch work out and then are confronted by the foods that caused their unhealthy weight gains. The Red team wins the first challenge - pulling a plane - and receives letters from home. The Blue team wins the weigh in with 20+ pound losses by Kae, Neil and Jerry, the week's Biggest Loser, with a percentage weight loss of 10.44%. The Red team votes (4 out of 5) to eliminate Amber.

The teams face a temptation - the player who consumes the most calories in four minutes wins a 3-pound pass at the weigh in. Nobody on the Black team or Red team partakes in the challenge. Neil eats 1700 calories but his teammate, Patty, consumes over 2000 calories despite a team agreement that Neil be the only team member to eat. Bob and the Blue team hash out sore feelings after the temptation before hitting the gym. The challenge pits the teams against children in three 100-meter dashes.

Jerry is revealed to have lost 88 pounds since starting the show and encourages other seniors to make a change as well. Week 4
This week, the trainers face a temptation - they must eat cupcakes to win their team a 15-second advantage in the upcoming challenge. Neil pushes Bob to play for the Blue team, but in the end, none of the trainers eat. The challenge has teams running down a hill to retrieve their flags. However, teams must bid how quickly they believe they can do it. The Black team bids that they can do it in 5 minutes, 25 seconds. However, they fall short by just a few seconds and are eliminated from the challenge. The Red team bids that they can do it in 5 minutes, 55 seconds. Phil plants the flag with 30 seconds left and gets his teammates to the flag with 18 seconds to spare. They earn immunity, though this is not revealed until the weigh in. Bob is disappointed that his Blue team didn't attempt the challenge. The Black team wins the weigh in, carried Jim (-11 pounds), Julie (-7 pounds), and Bill (-13 pounds), this week's Biggest Loser with a percentage weight loss of 4.36%. Without immunity, the Red team would be up for elimination. Instead, it is the Blue team that heads to the elimination room. The Blue team votes (3 out of 5) to eliminate Patty. Patty is revealed to have lost 61 pounds since she first came to the campus. Week 5
Alison announces that the kitchen is shut down, the gym is locked and the dorms are off limits. In other words, the teams are all headed to Jamaica.

During the challenge, the team members must take turns to carry a weighted frame as far as they can. The team that moves their frame the furthest wins. Despite falling behind early, Phil makes up a ton of ground and wins the challenge for the Red team. David and Kim exchange words over his speed on the treadmill. Jillian and Hollie receive word that Hollie's mother has suffered a relapse in her battle with leukemia. Hollie temporarily leaves the ranch to be with her mother, and the other players find out at the weigh in that Hollie's mother has died. The Blue team wins the weigh in with big losses from Ryan and Kae. Bill is the Biggest Loser,  with a percentage weight loss of 3.94%. Kim tells the Red team that Phil and Bryan are carrying the team, significantly angering Amy. The Red team's vote results in a tie, so the Blue team decides to eliminate Phil over Amy. Phil reveals to viewers that he has lost 108 pounds and is now more active with his daughter. Week 7
The teams are dissolved and the players are divided into teams of three. The players face a temptation. They play a game of high-low where the chips are high calorie treats. Anything a player bet, they had to eat. Jez wins the temptation after calling Amy's bluff and earns the right to pick the new trios. Jez gets input from all the other players before making his decision. Kae, David and Hollie make up the first trio while Amy, Julie and Bill make up the second trio. Bryan, Nicole and Ryan make up the third trio, while Jez takes Neil and Isabeau for the last trio. The players seem in a consensus that Jez put the teams together fairly. Amy feels betrayed by Kim's honesty and decides to train with Jillian. The Black team is upset that Amy is infringing on their time with their trainer. At the challenge, one teammate must push a heavy metal arm in a circle while their teammates stood on top of it. Bill carries his trio to victory, and he, Amy and Julie win a home gym. At the weigh-in, Jez's strategy backfires on him as Neil throws the weigh-in and gains 17 pounds, forcing himself below the yellow line with Jez and Isabeau. Kae, Hollie and David win the weigh-in and Bill is the Biggest Loser, with a percentage weight loss of 2.61%. After the weigh-in, Neil immediately heads to bed to avoid the other players while the Black team speculates what Neil's plan was and who else was in on it. David confronts Neil about throwing the weigh-in and convinces him to face the rest of the players. Neil initially denies gameplay, but eventually admits he threw the weigh in to force the elimination of a former Black team member. Bob is furious with Neil's gameplay, and Jillian is devastated when she learns that Neil betrayed his trio. At elimination, Julie, Bill and Amy vote to send Neil home, but the other two trios vote to send Jez home. Jez is revealed to have lost 103 pounds since starting the show and has moved to California to start a new lifestyle. Week 8
The players express their disappointment in Neil's gameplay. Amy reveals that she was pressured by Neil to join him in throwing the weigh-in. The trainers try to convince the players to forget the game and get back to losing weight. The challenge tests the players' endurance by seating them on a platform over water and having them hold up their own weight by a rope. Ultimately, Ryan, Bryan, and Nicole are the last remaining team and for winning, they receive the ability to vote individually at the elimination rather than as a team providing they do not fall below the yellow line. Behind Neil's 33 pound loss, he and Isabeau win the weigh-in. He also records the highest weight loss in one week of The Biggest Loser. David, Hollie and Kae fall below the yellow line and are up for elimination. Neil is this week's Biggest Loser, with a percentage weight loss of 8.87%. The trio of Bryan, Ryan and Nicole each hold individual votes from the reward challenge. Neil and Isabeau vote for David to alleviate concerns about a Red/Blue alliance. Bill, Julie, and Amy also vote for David, citing concerns about David's enormous potential. Bryan votes for Kae, but Nicole casts the deciding vote to eliminate David. David is revealed to have lost 105 pounds since beginning the show. Week 9
Alison announces Green Week and informs the players they will be abandoning trios and pairing off into duos. The player that comes closest to guessing the amount of calories in a large meat pizza and a soda will get to choose their duo, who in turn will choose the next duos. Nicole has the closest guess and wins control of the game. She chooses Neil as her partner. Neil and Nicole put Ryan and Isabeau together as a duo, who in turn put Julie and Bill together. Ultimately, Hollie and Bryan and paired together which leaves Amy and Kae as the last duo. Kae is not happy with Amy as her partner, given Amy's poor performance and attitude. Bob motivates her by putting a literal "X" on her back. In accordance with Green Week, the players are not allowed to use any electricity - for workouts or for cooking. During the challenge, the duos have 30 minutes to transport as many cans as they can into a bin. The pair that recycles the most cans will win a 2008 Ford Escape Hybrid SUV. Ultimately, after hauling 98.4 lbs. of cans, Bill and Julie win the challenge. The victory is especially rewarding for Julie who had to give up her car to become a stay-at-home mom. Neil and Nicole win the weigh-in, and Isabeau and Ryan fall below the yellow line, despite a nine-pound loss from Isabeau. Neil is this week's Biggest Loser with a percentage weight loss of 5.31%, and becomes the 5th contestant in the history of the show to lose 100+ pounds on the ranch. Each duo votes to eliminate Ryan. An update reveals that Ryan has lost 109 pounds since starting. Week 10
Alison reveals that from here on out, the players will be competing as individuals. Amy dons a black shirt and returns her red shirt to Kim, who is still upset over Amy's departure. In a temptation the players eat donuts, searching for a token worth $5,000. All the contestants except Kae participate and ultimately Bill finds the token. At the challenge, the players compete in a 24 km (15 miles) tri-athalon (20 km biking, 3 km running, 1 km swimming). Hollie wins and is granted a 24-hour trip home to see her family and immunity. Additionally, Hollie gains the power to give another player a 24-hour trip home and immunity and chooses Julie. If either Hollie or Julie gain weight, their immunity is void and they can fall below the yellow line. Hollie and Julie return from their visit home in time for the weigh-in and both women lost zero pounds. Due to their immunity, Bryan and Amy fall below the yellow line. Bill is this week's Biggest Loser with a percentage weight loss of 3.31%, and becomes the 6th Biggest Loser contestant to lose 100 pounds while at the ranch. The three Blue team players vote to eliminate Amy and the three Black team members vote to eliminate Bryan. Isabeau breaks from the black team and votes to eliminate Amy. Amy reveals in an update to have lost 100 pounds since starting the show. Week 11
