How eating rhythms impact the brain

The circadian clock system is responsible for aligning our internal processes at optimal times of the day based on cues from the environment such as light or food.

• Although the main clock manages metabolic function over the day-night cycle, our eating rhythms also impact the main clock. 
• When the main circadian clock in the brain is out of sync with eating rhythms, it impacts the brain’s ability to function fully. Even though the brain is only 2% of our total body mass, it consumes up to 25% of our energy.  So abnormal meal times are bound to have negative health outcomes.
