Overview
- Mass General Brigham researchers reported in Communications Medicine that meal timing tracked over two decades in 2,945 UK adults aged 42–94 was tied to later-life outcomes.
- Participants who habitually ate later—especially those delaying breakfast—had lower 10-year survival (86.7%) than earlier eaters (89.5%), with associations remaining after standard adjustments.
- Later timing correlated with depression, fatigue and oral-health problems, and people tended to move breakfast and dinner later with age, particularly those with an eveningness genetic profile or health challenges.
- The authors recommend consistent meal schedules for older adults and caution that time-restricted eating or intermittent fasting may affect younger and older people differently.
- The analysis is observational and limited by cohort composition and missing data on snacks and activity, so the findings indicate association rather than causation.
