When you eat matters: early breakfast plus longer overnight fasting linked to lower BMI

A large cohort study from ISGlobal with over 7,000 adults found that extending the overnight fast and starting the day with an early breakfast are linked to lower BMI years later, likely because earlier eating aligns with circadian rhythms and improves calorie burning and appetite regulation. Skipping breakfast as part of intermittent fasting did not reduce weight and may reflect unhealthy lifestyle patterns. Gender differences and lifestyle patterns emerged, and researchers caution that findings are observational and not yet definitive.
