What is biological age?

Chronological age is the number of years since birth. Biological age reflects the actual condition of your body and can be lower or higher than your chronological age, depending on diet, sleep, movement, stress, smoking, alcohol consumption and other lifestyle factors.

How is it calculated?

This calculator starts from your real age and applies a series of correction factors based on your answers to 28 questions about lifestyle and health status. The result is an indicative estimate, for educational purposes — not a medical diagnosis.

How can you lower your biological age?

A balanced diet (mostly plant-based), proper hydration, sufficient sleep, regular movement and stress management all help slow down aging. Natural regeneration processes, such as autophagy activated during responsible extended fasting, can support the body's recovery.
