Time-restricted eating (TRE), which typically limits eating to an 8-hour window, is popular for its supposed health benefits, yet its long-term impact on mortality remains unclear. A study presented at a recent American Heart Association scientific meeting investigated TRE's effects on all-cause, cancer, and cardiovascular mortality in 20,078 adults. Results showed no association between 8-hour TRE and decreased all-cause or cancer mortality.
Surprisingly, it linked 8-hour TRE with increased cardiovascular mortality, especially among individuals with pre-existing cardiovascular disease or cancer. Additionally, eating durations over 16 hours daily were associated with lower cancer mortality in cancer patients. These findings challenge the efficacy of 8-hour TRE for longevity or cardiovascular health improvement, suggesting the need for further research and personalized dietary…
