Core Tip

Core tip: Breakfast skipping (BS), late-night dinner eating (LNDE), and short duration of sleep have attracted attention because they elicit similar health risks: Obesity and type 2 diabetes. However, to-date these factors have been considered separately in terms of their health risks. LNDE and BS may be representative unhealthy eating habits around sleep (UEHAS). It is important to take energy in the early morning, whereas attaining a fasting state is essential for metabolic homeostasis. Therefore, BS or taking a very low energy breakfast may prevent obesity and diabetes in people with LNDE. Consideration of UEHAS and short sleep deserves further study.
