Extended fasting can lead to a unique microbiota that thrives on mucus, raising concerns about potential inflammation as these microbes get too close to host tissue. While short-term fasting may offer metabolic benefits, the long-term effects on gut health remain unclear. Caution is advised with cleanses and flushes, as they can disrupt the established microbial community, leaving recovery to chance. Adjusting dietary habits post-cleanse is crucial for rebuilding a healthy microbiota.
