Drew Barrymore

Drew Barrymore’s weight loss journey has been open and relatable. In early 2025 the one-time vegan lost around 20 pounds through diet and exercise, following a flexitarian approach that is heavy on vegetables but also includes fish and chicken from time to time. While she’s admitted to weight fluctuations, Drew emphasizes feeling healthy and strong, not fitting a specific size.

Mariah Carey

Mariah Carey’s weight loss journey has been shrouded in some secrecy. Rumors swirled about gastric sleeve surgery in 2017, which she’s never confirmed. According to one insider, she follows a low-carb, low-sugar diet, ditching processed foods and sugary drinks that were once a mainstay of her diet. While her exact methods remain unclear, she has spoken about her journey in general terms, crediting a post-pregnancy weight loss of 70 pounds to diet and exercise, with the first 40 pounds attributed to water weight reduction.
