Researchers say eating earlier in the day, particularly having dinner around 6pm, may improve metabolism, reduce disease risk and support healthier ageing.
Scientists are increasingly promoting “chrononutrition” — eating in sync with the body clock — as research suggests early dinners may help control weight, lower cancer risk and slow ageing. Experts say consuming most calories earlier in the day better aligns with natural metabolic rhythms and improves sleep, digestion and overall health.
Satchin Panda of the Salk Institute said eating dinner around 6pm gives the body more time for overnight repair processes. “It’s what we do in the six hours between sunset and midnight that determines our health,” Panda said, adding that eating late can disrupt circadian rhythms and increase long-term health risks.
Researchers in Japan also recommend protein-rich breakfasts to maintain muscle strength with age. Experts say leaving at least three hours between dinner and bedtime and eating lighter evening meals may significantly improve long-term wellbeing.
