WeightWatchers has filed for bankruptcy in the US as it struggles with debt and fierce competition from fat-loss jabs like Ozempic and Mounjaro. The legal process will see $1.15bn (£860mn) of the 60-year-old diet brand's debt written off while it agrees new terms for paying back its lenders.

Reuters reported in April 2025 that WeightWatchers' stock, which traded as high as $100 in 2018, lost most of its value last year as the company faced revenue declines, liquidity concerns, and celebrity shareholder Oprah Winfrey's decision to exit its board.
