In the complex ballet of organic processes that maintain the human body ticking, the function of clock genes is an efficiency important to recognizing how our bodies function efficiently. These genes, important to the circadian rhythms that govern our 24-hour biological cycles, have a profound impact on our metabolic rate, affecting every little thing from exactly how we process foods to exactly how we manage power. This interesting interplay between our hereditary make-up and our metabolic processes clarifies why some individuals might be night owls, brimming with energy when the moon is high, while others are early birds, catching the worm at dawn. The effect of clock genes goes past just influencing our sleep-wake cycles
