Do you remember The Biggest Loser? It ran for 17 seasons before an unexplained cancellation in 2016.
The reality show featured contestants fighting each other to lose the most weight over the 11-week time frame.
Biggest Loser features aggressive trainers who wouldn't let people stop until they were literally passing out, and junk food temptation challenges.
Overall, it showed its contestants the wrong way to lose weight. Most of the contestants ended up gaining all their weight back after the show ended anyways.
