The Effects of Intermittent Fasting on Gut Microbiota

The Effects of Intermittent Fasting on Gut Microbiota

A systematic review published in Frontiers in Nutrition examines the impact of intermittent fasting (IF) on the human gut microbiome. Intermittent fasting, a dietary approach that alternates between periods of eating and fasting, has gained popularity for its potential health benefits, including weight loss and improved metabolic health. This review aimed to understand how different types of IF affect the gut microbiome, which plays a crucial role in overall health.

The review analysed eight studies involving various IF methods, such as time-restricted eating, alternate day fasting, and the 5:2 diet. The findings suggest that IF can influence gut microbiota richness, diversity, and composition. However, the results across the studies were heterogeneous, indicating that the effects of IF on the gut microbiome can vary widely depending on the specific fasting protocol and individual dietary habits.

Overall, the review suggests that IF may have the potential to improve gut microbiota richness and alpha diversity, which could contribute to the health benefits associated with this dietary practice. However, due to the variability in results, more research is needed to confirm these findings and understand the implications of IF-induced changes in the gut microbiome for human health.
