It is well known that individuals who work night-shifts, or travel often across different time zones, have a higher tendency to become overweight and suffer from gut inflammation. The underlying cause for this robust phenomenon has been the subject of many studies that tried to relate physiological processes with the activity of the brain’s circadian clock, which is generated in response to the daylight cycle.

Their findings were published today in the scientific journal Nature.
