How eating feeds into the body clock

Circadian rhythms, or ‘body clocks’, are endogenous daily rhythms that occur in every cell of the body; affecting a wide range of physiological processes, from when we sleep, to hormone levels, to how quickly we metabolise drugs. Our internal body clocks are synchronised with the external day and night by the times when we eat and when we see light, and this is important for long-term health. Until recently, how our daily biological clocks sense and respond to feeding time was not understood.

John O’Neill and Priya Crosby describe how they identifed insulin as a primary signal that communicates feeding time to synchronise circadian rhythms throughout the body.
