In June 2019 researchers from Japan published the results of their study to assess the association between dietary habits and body weight. A total of 45,524 men, aged 20-49 years, were followed up for a period of 3 years. Information was collected via health check-up data. Results showed that 17,706 (39%) skipped breakfast and 25,987 (57%) had a late dinner (within 2 hours of bedtime). At the 3-year follow-up, 5,093 (11.2%) had a BMI of over 25 kg m-2. An analysis revealed that those who skipped breakfast were more likely to be overweight. However, having dinner within 2 hours of bedtime did not appear to increase the risk of being overweight.
