Circadian rhythms, the body’s natural 24-hour cycle, significantly influence metabolism, hunger, and the timing of eating. Disruptions in these rhythms, such as irregular eating patterns or eating late at night, have been linked to obesity. Studies show that eating meals earlier in the day, when the body’s metabolic rate is higher, supports healthier weight management. Late-night eating, on the other hand, can negatively impact insulin sensitivity and fat storage, making it harder to lose weight. Circadian eating patterns also influence appetite-regulating hormones, such as leptin and ghrelin. Aligning eating habits with the body’s natural rhythms can improve energy balance, reduce overeating, and support weight loss efforts. Research suggests that adopting time-restricted eating, which involves consuming food within a set time window during the day, may be a useful strategy for managing obesity.
