Human evidence on markers, not lifespan
For humans, the description says research is still growing. It reports evidence that intermittent fasting may improve insulin sensitivity, support cellular repair and reduce the risk of age-related diseases. These are possible health-marker effects, not demonstrated lifespan gains.
