Circadian rhythms are natural, 24-hour cycles that regulate various physiological processes, including sleep, metabolism, and hormone secretion. Disruption of these rhythms, often caused by irregular sleep patterns, shift work, or late-night eating, has been linked to an increased risk of obesity. When the body’s internal clock is misaligned with external factors, metabolic functions such as insulin sensitivity, fat storage, and hunger signaling become impaired. This leads to weight gain and difficulties in managing body fat. Studies suggest that aligning eating patterns with the body’s natural rhythms, such as eating during daylight hours and prioritizing good sleep hygiene, can help prevent obesity. Regular sleep-wake cycles and mindful eating habits are essential for maintaining metabolic balance and supporting long-term weight management.
