Late Dinner Culture

A cultural pattern of eating the main evening meal at 22:00–23:00 and going to bed within 1–2 hours — disrupting circadian metabolism, sleep quality, and digestion.

Why this habit matters

  • Health: Children in late-dinner households show shorter sleep, lower morning alertness, and weaker school-readiness markers; the Spanish Pediatric Association has flagged this as a structural pediatric health concern.
  • Metabolic: Eating large meals close to bedtime impairs glucose tolerance and insulin sensitivity (Garaulet et al.); the same calories consumed late produce more weight gain and worse glycemic profile than when consumed earlier in the day.
  • Sleep: A short gap between dinner and sleep reduces sleep depth, increases nocturnal awakenings, and worsens reflux; objective sleep-quality metrics decline measurably for late-dinner schedules.
