Delayed breakfast timing linked to increased cardiovascular mortality

A large-scale longitudinal study involving over 31,000 adults has linked the timing of the first daily meal to significant changes in mortality risks. Published in the ‘European Journal of Clinical Nutrition’, the research led by a team from Huazhong University of Science and Technology analyzed data from the National Health and Nutrition Examination Survey (NHANES).

The findings indicate that delaying the first meal past noon is associated with a 29% increase in all-cause mortality and a 46% surge in cardiovascular disease mortality. For adults aged 50, consistently eating the first meal after midday may reduce life expectancy by an average of 2.46 years. The study suggests that late eating disrupts the body's circadian rhythm, leading to metabolic disturbances in lipids and glucose.

Additionally, the timing of the final meal of the day also impacts health. The optimal window for dinner is between 7:00 PM and 8:00 PM. Consuming meals after midnight is linked to a 27% increase in all-cause mortality and a reduction in life expectancy by 2.35 years.
