Our Body Clock Regulates Our Metabolism

Scientists have discovered that your circadian rhythms regulate the energy levels in your cells. In addition, the proteins involved with circadian rhythms and metabolism are intrinsically linked and dependent upon each other. This finding has far-reaching implications, which could include new ways to treat cancer, diabetes, obesity and a host of related diseases.

………………………….

24-hour circadian rhythms govern fundamental physiological functions in almost all organisms. These circadian clocks are the essential time-tracking systems in your body. Disruption of these rhythms can profoundly influence human health.

In a new study, researchers showed that an enzyme protein which is an essential molecular gear of the circadian machinery interacts with a protein that senses cell energy levels and modulates aging and metabolism.

This suggests that proper sleep and diet may help maintain or rebuild the balance between your circadian clock and your metabolism, and could also help explain why lack of rest or disruption of normal sleep patterns can increase hunger, leading to obesity-related illnesses and accelerated aging.
