The short answer is yes, current biological evidence suggests that intermittent fasting can significantly influence the biomarkers of aging by triggering cellular repair mechanisms and improving metabolic flexibility. While human longevity trials are difficult to conduct over decades, the data from caloric restriction mimetics and periodic abstinence shows a clear trend toward delayed senescence. Does intermittent fasting slow aging? It appears to do so by forcing the body out of a constant growth mode and into a state of preservation and maintenance. If you have ever wondered why your body seems to thrive under a bit of pressure, the secret lies in our evolutionary blueprints.
