Earlier Breakfast and Dinner Linked to Lower BMI, Study Finds
A 7,074-person ISGlobal study followed adults for five years and found that finishing meals earlier, eating breakfast earlier, and extending the overnight fast are associated with lower BMI. The findings, stronger in premenopausal women, suggest circadian-aligned eating may aid weight management, while late breakfast and more frequent meals correlated with higher BMI; a subgroup of men who skipped breakfast showed no weight benefit. The study is observational and cannot establish causation, highlighting the need for trials on chrononutrition.
