Jillian Michaels came under fire with the release of Netflix's The Biggest Loser tell-all docuseries - and she was quick to take back the narrative. In Fit for TV: The Reality of the Biggest Loser, which premiered in August, celebrity trainer Michaels was criticized for her controversial moments on the reality show. (She was a trainer on the weight loss series intermittently from 2004 to 2014.) Michaels received backlash following a 2013 episode in which she was accused of cheating when she allegedly allowed her team to take caffeine pills without a doctor's permission.
