According to a study published in *Nature*, fasting can trigger gut bacteria to produce a metabolite that is required for regenerating nerve fibers. This exciting research reveals that going without food for periods can induce a profound metabolic shift, causing a cascade of adaptive responses that powerfully affect nerve cells.

Despite making up only about 2% of body weight, the brain consumes around 20% of the body's total energy, primarily relying on glucose as its preferred fuel for most body functions, especially for nerve cells, including those of the brain. This remarkable energy demand and reliance on a single fuel source is critical for maintaining cognitive function and survival.
