UK adults eat dinner late (7-9pm typical) compared to many European countries. Late dinner produces worse sleep, more reflux, slower overnight fat oxidation. Earlier dinner (5-6pm) has measurable benefits.
What earlier enables
Better sleep quality (digestion done before bed). Less reflux. More fasting hours overnight. Time for evening walk between dinner and bedtime.
Where this is hard
Work schedules. Family schedules. Cultural norms. Try moving dinner one hour earlier for two weeks; observe what changes.
