Evidence-Based Biological Age Calculator
Comprehensive longevity assessment based on Blue Zones research, Framingham Heart Study, and validated aging biomarkers
About This Biological Age Calculator
Our evidence-based biological age calculator uses validated longevity research from Blue Zones, the Framingham Heart Study, and major meta-analyses to estimate how your lifestyle factors affect aging. This comprehensive assessment evaluates 25+ scientifically-proven factors including exercise, diet, sleep, stress, social connections, and health biomarkers to provide personalized insights into your biological age and actionable recommendations for healthy aging.

Frequently Asked Questions
Chronological age is the number of years you've been alive, while biological age reflects how old your body appears based on various biomarkers and lifestyle factors. Research shows biological age can differ significantly from chronological age and is a better predictor of health outcomes and longevity.
This calculator provides educational estimates based on major population studies including Blue Zones research, the Framingham Heart Study, and longevity meta-analyses. However, true biological age requires laboratory biomarkers like telomere length, DNA methylation, and inflammatory markers. Use results as a general guide, not medical diagnosis.
Research shows biological aging can be slowed and potentially reversed through lifestyle interventions. Studies demonstrate that changes in diet, exercise, stress management, and social connections can reduce biological age markers by 3-5 years within 12-24 months.
Based on extensive research, the top factors are: not smoking (adds 10+ years), regular physical activity (3-7 years), Mediterranean-style diet (2-4 years), strong social connections (3-5 years), optimal sleep (2-3 years), and stress management (2-5 years).
Women live approximately 5 years longer than men on average due to biological advantages including XX chromosome protection, estrogen's cardiovascular benefits, stronger immune function, and generally healthier lifestyle behaviors. This calculator accounts for these gender differences based on research.
