One of the brightest reality TV hits from the 2000s and 2010s was The Biggest Loser, which saw people compete to lose the biggest percentage of weight for a cash prize by the end of the season. Though we’d known that participants on the 18-season series endured some pretty insane things to lose weight during the competition, a docuseries that just hit the 2025 TV schedule (which you can watch with your Netflix subscription) has put new focus on those methods and one of the show’s trainers, Jillian Michaels. Now, an OG contestant has spoken about his relationship with her while appearing on the hit.
