Why 'The Biggest Loser' Was The Worst Show Ever
What this video covers
This is criticism, not celebration — and it belongs in the chronicle precisely because the show it attacks is the one that made Jillian Michaels famous. Dr. Mikhail “Doctor Mike” Varshavski, a physician and one of YouTube’s largest medical creators, uses his platform to argue that “The Biggest Loser” was one of the most harmful shows ever put on television. The video landed in August 2025, days after Netflix released “Fit for TV: The Reality of The Biggest Loser,” the docuseries that supplied most of the allegations he discusses. Michaels herself did not participate in the Netflix documentary.
Doctor Mike’s case, as presented in the video and in the reporting around the documentary, runs through the show’s methods: contestants reportedly consuming as little as 800 calories a day while working out eight or more hours, multiple hospitalizations, and at least one near-death — season 8 contestant Tracy Yukich, who collapsed from rhabdomyolysis during the first challenge. He cites the well-known NIH follow-up research finding that contestants’ metabolisms slowed dramatically and never fully recovered, meaning many regained the weight while burning fewer calories than before. He also relays the documentary’s allegations that trainers — including Michaels — acted as pseudo-therapists, gave contestants caffeine tablets, and berated them, and that fellow trainer Bob Harper allegedly distributed Adderall, a claim Harper has denied.
The slash-and-burn tone is the point of the genre — Doctor Mike’s brand is debunking — but the underlying material is the contestants’ own testimony. The documentary’s producer is quoted saying that on “The Biggest Loser,” “the entertainment value of the show far outran the health aspects of the show.” For this site’s purposes, the video is the strongest single statement of the case against the methods of the show that built Michaels’ career, and it is presented here as that: a critic’s argument, sourced to the documentary and the studies he cites, not as the site’s verdict.
Key points
- Doctor Mike argues “The Biggest Loser” harmed its contestants: extreme calorie restriction (reportedly ~800 calories/day), 8+ hour workout days, vomiting, and multiple hospitalizations.
- He cites the NIH follow-up research on contestants, which found severe metabolic adaptation — metabolisms slowed and stayed slow, making long-term weight maintenance extraordinarily difficult.
- The video relays the Netflix doc’s account of season 8 contestant Tracy Yukich collapsing from rhabdomyolysis during the first challenge — described as the documentary’s most striking moment.
- Allegations discussed include trainers giving contestants caffeine tablets and acting as unqualified therapists; Bob Harper is alleged to have distributed Adderall, which he has denied as “absolutely false.”
- Michaels, one of the show’s two star trainers, did not participate in the Netflix docuseries; the video’s critique of the show’s methods therefore lands on her legacy without her rebuttal in the frame.
- The video is best read as the prosecution’s brief: it is a physician-creator’s argument, built on contestant testimony and published research, and it represents the critical side of the for/against record on Michaels’ signature show.
