The Biggest Loser Show

The basic premise of the show is that obese people become contestants who are competing to win $250,000 (originally $100,000) by losing the highest percentage of weight (originally, the winner was to lose the highest amount of weight in pure numbers, but this was later changed to the highest percentage of weight in order to evenly rebalance the playing field). The first season began with 12 contestants, while the second season began with 14. The third season began with 50 contestants, one from each state (14 on the Ranch). The fourth season began with 18 contestants divided into 3 teams. The fifth season began with ten teams of two people each, and the sixth seasons began with 8 teams of two. The seventh season began with 11 teams of two, and the ninth season is expected to start the same way. The 8th season saw the return of the original format, with individuals competing for the grand prize. But like the previous 3 seasons, they were divided up into teams of two, with each contestant choosing a team partner.
In the first three seasons, contestants were housed on a large ranch that offered plenty of indoor and outdoor space, a pool and a fully equipped gym. In the fourth season, the ranch was changed and renamed college campus, known on the show as the Biggest Loser Campus. In the fifth season, the contestants' setting reverted to a ranch.
At the start of each season, contestants are grouped into teams and each team is assigned a personal trainer. For the first 3 seasons and seasons five through seven, there were two teams and two trainers, while the fourth season featured three teams and three trainers. The trainers are responsible for designing and teaching to the contestants comprehensive workout plans and nutrition plans. It is up to the contestants, however, how much or how little of the nutrition plan to implement, and how much of the workout plan they follow when the trainer is not present.
The season starts with a weigh-in to determine the contestants' starting weights. Each week culminates in another weigh-in to determine which team has lost the most weight for that week, in percentage of total weight lost. The team that has lost the lower percentage during that week must vote off one member of the team.
