Abstract: Chronobiology investigates how biological rhythms synchronize with the Earth's 24-hour cycle, known as circadian rhythms, influencing various physiological processes, including metabolism. This abstract explores the intricate relationship between chronobiology and metabolism. Circadian rhythms regulate metabolic pathways, impacting nutrient utilization, energy expenditure, and hormone secretion throughout the day-night cycle. The core molecular clock, comprising transcriptional-translational feedback loops, orchestrates the rhythmic expression of genes involved in metabolic regulation. Disruptions to circadian rhythms, such as shift work or jet lag, can lead to metabolic dysregulation, increasing the risk of obesity, diabetes, and cardiovascular disease. Conversely, the metabolic state influences circadian rhythms, forming a bidirectional relationship. Nutrient availability and feeding patterns can entrain peripheral clocks in metabolic tissues, modulating metabolic processes in anticipation of feeding. Moreover, metabolic intermediates serve as signaling molecules, influencing clock gene expression and circadian output. Understanding the interplay between chronobiology and metabolism is crucial for developing targeted interventions to improve metabolic health and prevent associated disorders. Chrono-nutrition, timing meals to align with circadian rhythms, emerges as a promising approach to optimizing metabolic health. Furthermore, chronotherapeutics, including timed administration of medications, hold the potential for enhancing treatment efficacy while minimizing side effects. Overall, elucidating the intricate connections between chronobiology and metabolism offers insights into fundamental biological processes and avenues for promoting health and well-being.
