# The Biggest Loser

The Biggest Loser is a reality television format which started with the American TV show The Biggest Loser in 2004. The show centers on overweight and obese contestants attempting to lose the most weight; the winner receives a cash prize. There are different variations of The Biggest Loser around the world. Each country has made its own adaptation of the show; however, the contestants always have the same goal: to lose the highest percentage of weight (or most weight) to become the "biggest loser". There is no minimum or maximum weight limit for the show, but most males tend to weigh over or near 300 lb (136 kg). Females tend to weigh over or near 200 lb (91 kg).
In addition to individual contestants, some seasons in some international adaptations have featured couples or even whole families.
