Time-restricted eating aligns feeding patterns with circadian rhythms, which can improve metabolic health. The daily 16-hour fast promotes metabolic switching from glucose to fat-based energy and may activate cellular cleanup processes (autophagy), which are linked to enhanced cellular resilience and reduced inflammation.
