Meal timing influences metabolism as it affects the body's internal clock, known as the circadian rhythm. Eating at regular intervals can optimize insulin sensitivity, leading to better energy utilization and fat metabolism. Additionally, meal timing can affect hunger hormones, making it easier to manage appetite and maintain a healthy weight. Research indicates that aligning meal times with natural biological rhythms can enhance performance and overall metabolic function, emphasizing the importance of considering not just what we eat, but also when we eat.
