Intermittent fasting can affect gut microbes in several ways. When bacteria are put on a fast in mice, fruit flies, or other organisms, they live longer and show increased resistance to oxidative stress and xenobiotic stress (exposure to chemicals such as in chemotherapy). Fasting also increases microbial diversity and the microbes’ tolerance to harmful bacteria, and it can restore the intestinal epithelium, i.e., the lining of the colon. Additionally, fasting starves sugars for yeast and Candida, reducing pathogenic microbes and supporting the growth of beneficial populations. These microbes contribute to the body by recycling and increasing bile acids, which help digest fats. Overall, fasting appears to enhance microbe longevity, diversity, and resilience, while supporting gut lining health and fat digestion through bile acid production.
