"After helping hundreds of contestants transform their lives and inspiring millions of viewers at home, 'The Biggest Loser' and Jillian Michaels have decided to part ways and she will not be returning for season 16 when it airs in the fall," a statement from NBC read.

This marks Michaels' third departure from the series. She first left in 2006, missing season three of the competition. Later she said goodbye again in 2011, sitting out both seasons 12 and 13.
