Weekend meal shifts linked to higher heart disease risk in men

A new study finds that shifting meal times between weekdays and weekends, called eating jetlag, is linked to a higher risk of cardiovascular disease in men, with each hour of shift raising risk by 14%. Researchers analyzed data from over 100,000 participants in the NutriNet-Santé cohort over 14 years. For men, each additional hour of eating jetlag was associated with a 21% higher risk of coronary heart disease, but no significant association was found in women. The study, published in Communications Medicine, suggests that maintaining consistent mealtimes between weekdays and weekends may help resynchronize biological rhythms, independent of sleep and diet. Further research is needed to establish causality.
