Meal timing linked to longevity in US study

A long-term study involving over 31,000 adults in the United States suggests that the timing of the first and last meals of the day is significantly linked to longevity and cardiovascular health.

Based on data from the National Health and Nutrition Examination Survey (NHANES) tracked over approximately ten years, researchers found that delaying the first meal increases mortality risk. Compared to those consuming their first calories between 07:00 and 08:00, individuals delaying breakfast past 08:00 saw a risk increase of 10% to 19%. Those delaying their first meal until the afternoon faced a 29% higher mortality risk and a 46% higher risk of death from cardiovascular disease, with an average lifespan reduction of about 2.5 years.

Regarding evening meals, the lowest mortality risk was observed in those eating their last meal around 20:00. Those finishing before 19:00 saw a 13% increase in risk, while those eating after midnight saw a 27% increase. Dr. Zhilei Shan of Huazhong University of Science and Technology noted that meal timing is a critical indicator for the body's biological rhythm, as irregular timing can disrupt glucose and fat metabolism.
