How does our diet affect circadian rhythms?

Diet Composition Matters But So Does Meal Timing

Bright light in the morning entrains the master clock in your brain. The food-entrainable oscillator (FEO) kickstarts circadian rhythms in peripheral tissues when you eat breakfast (eg, Polidarova et al., 2011 and Sherman et al., 2012).

These two events (ie, bright light and food intake) should be timed together to co-entrain central and peripheral circadian rhythms.

If optimal circadian is your goal, follow a low carbohydrate and either high fat or high protein.

Avoid smart devices at night or get some blue-blockers to prevent a circadian phase delay. Eat well, sleep well, be well.

Hi, I’m Bill. I have a Ph.D. in Nutritional Biochemistry and Physiology from Rutgers University where my dissertation focused on fatty acid-binding proteins and energy metabolism. I studied inflammation and diabetes at UCSD. And most recently, I studied circadian biology at the Mayo Clinic. I have a broad range of knowledge about health, wellness, sickness, and disease… and I’m learning more every day!
