Eating jetlag and the risk of cardiovascular disease

What the research found
Study (observational). INRAE’s Bernard Srour and colleagues analysed 104,806 adult NutriNet-Santé participants (2009–2023) and report in Communications Medicine that weekday–weekend meal-timing shifts (“eating jetlag”) tracked with cardiovascular disease in men: each extra hour of advance or delay was associated with about 14% higher CVD risk and 21% higher coronary risk after sleep, diet, and lifestyle adjustment. No significant association was seen in women. Advance averaged about 2 hours earlier on weekends; delay about 1 hour 40 minutes later. Observational, not proof that regular mealtimes prevent heart disease. Educational timing notes, not medical advice.
Evidence level: Human study. A study in people, but an association isn't proof of cause.
