Intermittent fasting is a popular way to improve health and this study explores its effects on gut microbiota (GM), which also has many positive effects on the body. The study used a male rat as a model and found that 18-hour fasting for 5 weeks led to an increase in bacterial diversity and balanced the GM composition. This was shown by analyzing the metagenome of the cecum content in the rat’s intestines. The results indicate that intermittent fasting is a beneficial practice for shaping GM, which has numerous health benefits. By stabilizing the ratios of Firmicutes and Bacteroidetes and reshaping values with high prevalence, intermittent fasting helps improve GM composition. This study highlights the strong positive link between intermittent fasting and GM and encourages exploring the effects of different fasting practices on GM for better health.
