The popular reality TV show ‘The Biggest Loser’ has left many wondering about the hosts of the show and where they are now. The show, which aired from 2004 to 2020 on NBC and later on the USA Network, garnered significant attention with its weight loss competition format. The hosts of the show – Caroline Rhea, Alison Sweeney and Bob Harper – played pivotal roles in guiding contestants on their journey to lose weight and change their lives.

The Netflix docuseries ‘Fit for TV: The Reality of the Biggest Loser’, released in 2025, delves into the behind-the-scenes of the show and features interviews with Harper and Sweeney, shedding light on the impact the show had on its participants.

Rhea has also continued her stand-up comedy career, performing at clubs and festivals globally, while voicing characters in popular children’s shows.

Alison Sweeney took over hosting duties from Rhea in 2007 and remained with the show for eight years. After leaving ‘The Biggest Loser’, Sweeney focused on her acting career, continuing her role in ‘Days of Our Lives’ and appearing in various Hallmark Channel movies.
