A new study shows that fasting can create significant changes in brain regions connected to appetite control and addiction. Analyses of stool and blood samples also revealed notable shifts in gut bacteria, particularly increases in Coprococcus comes and Eubacterium hallii. Published in *Frontiers in Cellular and Infection Microbiology*, the research highlights the close relationship between fasting, gut microbiota, and brain function.
Participants in the study lost an average of 7.6 kilograms (16.8 pounds) and experienced measurable changes in both gut bacteria composition and brain activity. One of the key findings was reduced activity in the left inferior frontal orbital gyrus, a brain region that helps regulate food intake. This suggests that intermittent fasting may encourage the growth of beneficial gut bacteria that produce compounds capable of influencing brain function, especially in areas related to appetite and impulse control.
The results support the idea of a dynamic gut-brain connection, where changes in gut bacteria can directly shape brain activity and potentially influence eating behaviors and decision-making about food. In addition to weight loss, intermittent fasting has been linked to improved metabolic health, sharper cognitive function, and possible longevity benefits, making it a promising approach for overall well-being.
