The Biggest Loser is slimming down and returning to NBC's fall schedule.

NBC has announced it has renewed The Biggest Loser for a fifteen season which will air this fall as part of the network's 2013-2014 primetime programming schedule.

The reality weight-loss competition's fifteenth edition, which will consist of one-hour episodes, will air Tuesdays at 8PM ET/PT and serve as NBC's lead-in to The Voice's fifth-season results show broadcasts.

The edition will be the first The Biggest Loser edition to air in the fall season since the show's thirteenth season aired in Fall 2011 and the first edition regularly broadcast in a one-hour format since its Fall 2006 third season.

(After airing The Biggest Loser's Fall 2007 fourth season in a 90-minute format which also featured occasional two-hour episodes, NBC expanded the long-running reality franchise to a regularly-scheduled, two-hour format beginning with its Spring 2008 fifth season, which also marked the first time the network aired two regular The Biggest Loser editions in the same television season.)

In addition, the scheduling will also mark The Biggest Loser's return to Tuesday nights -- where, prior to last season's move to Monday nights, it had aired since Fall 2007.

The Biggest Loser: Challenge America, the show's fourteenth season, premiered in January and concluded in March with Dannielle "Danni" Allen being crowned the season's winner.

NBC had announced open casting calls for The Biggest Loser's fifteenth season last month.
