This Medical News feature discusses the role of circadian clock in regulating metabolism.

Now, the basic science is giving way to human studies that reveal how a person’s sleeping habits, eating patterns, and diet may desynchronize the body’s clocks and contribute to metabolic problems like obesity or diabetes.

The findings have led scientists on a hunt for ways to reset the clock and restore healthy metabolism. So far, 2 behavioral interventions, improved sleep and time-restricted eating, show promise in animal and preliminary human studies.
