Impact: The response has sparked discussions about the ethics of reality TV, the treatment of contestants, and the long-term effects of such shows on participants’ health. It could influence public perception of Michaels and the ‘Biggest Loser’ franchise, potentially leading to renewed scrutiny of reality TV practices and calls for better regulations.
