'Biggest Loser' Contestants Threats to Quit, Stall Production: When Will Show Be Back?

Nearly all of the contestants from Season 13 of The Biggest Loser have stormed off the set of the NBC weight-loss show after a twist in the program revealed that some of the previously eliminated contestants would be coming back to the competition.

According to TMZ, the contestants felt bringing back more people to compete for the $250,000 grand prize was grossly unfair.

We're told most of the current contestants were pissed--feeling it was unfair that prior losers would get a second bite at the apple, the report read.

After learning of the producers' plans, the separate teams banded together and decided to protest by walking off the show in the middle of shooting an episode.

Production is reportedly shut down for at least a week, and producers are scrambling to figure out how to handle this situation. If the rumors are true, it's likely that the show honchos TMZ blames for the controversy will fold to the contestants' demands. After all, without its weight loss contestants, the only people left to compete for American audiences are the producers themselves.

The eighth episode of the show's 13th season aired Tuesday night. The weight loss competition continues to be one of NBC's most successful reality TV shows.

Representatives for NBC network and The Biggest Loser show have declined to verify or to comment on the TMZ report so far.
