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.

The company, which has shaped how millions eat and exercise, is trying to reduce its debt as it expands its telehealth business.
