Timing of Eating: From Body Clocks and Brain Signals to Human Eating Habits and Health Patterns

AI simplified

Abstract

Chrono-nutrition is associated with improved metabolic health by aligning food intake with circadian rhythms.

  • The circadian clock regulates daily biological rhythms, impacting physiology and behavior.
  • External cues, such as light and food timing, sync the central circadian clock in the brain and metabolic rhythms in the body.
  • Disruption of circadian rhythms can lead to negative metabolic outcomes, supported by both animal and human research.
  • Aligning food intake with optimal periods of metabolic activity may enhance metabolic health.
  • Eating patterns that distribute energy earlier in the day may improve glucose and lipid management, insulin sensitivity, and energy expenditure.
  • Human studies indicate potential benefits of morning versus evening meal timing and interventions like time-restricted feeding.
