Good news for late eaters and night owls: the common advice to wait two hours after dinner before bedtime isn't backed by science. This recommendation stems from worries that elevated blood glucose at night could disrupt sleep and raise health risks. Yet, a rigorous study from Okayama University in Japan challenges this, revealing minimal effects on blood sugar levels.
Researchers analyzed 1,573 non-diabetic adults aged 40 and older (two-thirds women), tracking HbA1c—a reliable marker of long-term glycemic control. The findings? Almost no difference in HbA1c levels between those who waited two hours post-meal before bed and those who didn't. Experts emphasize that lifestyle factors like exercise, body weight, smoking, alcohol intake, and blood pressure play far larger roles in blood sugar regulation. Prioritizing overall healthy habits trumps rigid meal-bed timing.
Sleep easy after a late dinner—no guilt required. It won't sabotage your rest or health.
