Foreign media: A study based on the U.S. National Health and Nutrition Examination Survey database, involving 14,012 participants, found that meal timing is closely related to the rate of biological aging, with late eating significantly associated with accelerated aging.
Regarding dinner timing, individuals who eat between 3 p.m. and 5 p.m. exhibit notably slower whole-body and cardiac aging compared to those who eat after 9 p.m.; however, eating too early (before 3 p.m.) actually accelerates aging of the heart and liver. The optimal window is between 5 p.m. and 7 p.m.
For breakfast timing, having the first meal later than noon (compared to before 8 a.m.) is associated with accelerated aging of the heart, liver, and overall body, while the kidneys remain unaffected. Eating intervals exceeding 16 hours are also linked to accelerated aging, whereas shorter intervals (under 8 hours) yield better outcomes.
Therefore, it is recommended to have breakfast between 7:00 a.m. and 7:30 a.m., lunch between 12:00 p.m. and 12:30 p.m., and dinner completed between 5:30 p.m. and 6:30 p.m.
Notably, these patterns vary among individuals: people over 40 are significantly influenced by meal timing, while younger individuals are less affected; men are more sensitive to the timing of the first and last meals, whereas women are more responsive to changes in fasting duration. Those with lower calorie intake are more impacted by meal timing rhythms, while high-calorie consumers show weaker associations. For individuals following healthy diets, delaying the first meal may instead accelerate whole-body and liver aging.
