The Biggest Loser

The Biggest Loser is shifting its focus from couples to cities by visiting America's fattest locales.

Executive producer J.D. Roth told The Hollywood Reporter that the show plans to cast the new season with people who hail from the "Fattest Cities in America." While it's unclear how it will be decided which cities are the heaviest, Men's Fitness, for one, compiles a list each year.

"We're going to try to cast in those cities and add things into those cities to help them change their ways and to get off that list," he said.

The series, now in its seventh season, is also set to return to the single contestant format.

The Biggest Loser: Couples debuted to 11.82 million viewers, its largest season opener ever.

You can catch an all new episode Tuesday at 8pm/ET on NBC.
