Tag: 22 hour fast

After approximately 18 to 24 hours of fasting, the body's primary energy source shifts significantly as its stored glycogen reserves become depleted. This metabolic change marks a deeper level of fasting than a standard overnight fast, triggering a cascade of physiological adaptations to sustain energy and promote cellular health.

During a fast of 20-24 hours, the body typically depletes its glucose stores and switches to burning fat for fuel. This metabolic state is central to understanding what are the benefits of a 22 hour fast and its profound impact on your overall health.
