Metabolic Age Calculator
The Metabolic Age Calculator estimates your physiological age based on your height, weight, gender, and activity level. This tool helps fitness enthusiasts and health-conscious individuals assess their biological age compared to their chronological years. Whether you want to track fitness progress, manage your weight, or monitor your overall health status, this calculator provides clear insights to optimize your lifestyle.
How Metabolic Age Is Calculated
Metabolic Age represents the age associated with your body's Basal Metabolic Rate (BMR). It compares your specific calorie-burning efficiency against average BMR values for different chronological age groups. This calculation uses the scientifically validated Mifflin-St Jeor equation to determine your baseline metabolic rate.
BMR = (10 × weight) + (6.25 × height) - (5 × age) + 5
Where:
- Weight is in kilograms
- Height is in centimeters
- The constant (+5) is for males (use -161 for females)
- Calculate your BMR using the Mifflin-St Jeor formula based on your inputs.
- Adjust your BMR by your activity level to find your Total Daily Energy Expenditure (TDEE).
- Compare your TDEE against standard metabolic averages to determine your metabolic age.
This method is widely used because it accounts for body composition and provides a credible snapshot of your metabolic health.
What Your Metabolic Age Means
Your metabolic age indicates if your body is aging faster or slower than your calendar years. A lower number suggests your metabolism is functioning efficiently, while a higher number may signal health risks.
Improve Health: If your metabolic age is higher than your actual age, your metabolism may be slowing down. Focus on resistance training to build muscle mass, which directly boosts your BMR and lowers your metabolic age over time.
Maintain Fitness: If your result is within 4 years of your chronological age, your metabolism is average. To improve this, gradually increase your workout intensity or protein intake to enhance calorie burning.
Elite Performance: A result 5 or more years younger indicates excellent metabolic efficiency. Continue your balanced diet and varied exercise routine to preserve this high level of health.
