Study Finds Fat Cells Exhibit Circadian Rhythms Affecting Critical Metabolic Functions

Fat cells in the human body have their own internal clocks and exhibit circadian rhythms affecting critical metabolic functions, new research in the journal Scientific Reports, finds.

Researchers led by Dr Jonathan Johnston from the University of Surrey conducted the first ever analysis of circadian rhythms in human fat taken from people isolated from daily environmental changes. Circadian rhythms are approximately 24-hour changes governed by the body’s internal clocks. Misalignment of ‘human clocks’ with each other and the environment is believed to be a major contributor to obesity and poor health.

During this unique study seven participants underwent regulated sleep-wake cycles and meal times before entering the laboratory, where they maintained this routine for a further three days.
