Gut bacteria and eating habits in circadian syndrome

Eating behaviour and circadian rhythms significantly influence the intestinal microbiota.

• The type, timing, and quantity of food consumed affect gut microbiota composition.
• Alterations in gut microbiota may influence food intake and circadian rhythms.
• Circadian disruptions caused by an obesogenic environment impact gut-brain axis signalling.
• Understanding the interactions between gut microbiota and circadian rhythms could help address unhealthy eating behaviours.
• These factors are linked to the ongoing obesity epidemic, a major societal challenge.
