Our bodies have a circadian rhythm that directs when we sleep, when we eat, what genes are active, and our metabolism.￼ It’s affected by light and by internal clocks that are present in most of our cells.￼
When that circadian clock is disrupted, it affects our health. For people who work the night shift, they eat at night and sleep during the day. People with this schedule are 40 to 60% more likely to be obese.
And our diet, circadian rhythm, and our micro biome might be interconnected.
