How to Calculate Metabolic Age
Metabolic age reveals how your basal metabolic rate (BMR) compares to others in your age group. Learning how to calculate metabolic age helps assess your body's energy efficiency, guides fitness goals, and identifies potential health risks. This crucial health metric helps you make informed decisions about diet, exercise, and lifestyle changes for better wellness outcomes.

Metabolic Age Formula
The metabolic age calculation uses: Metabolic Age = (BMR / 24) + (0.85 × Chronological Age). BMR is calculated using Mifflin-St Jeor equation:
Men: BMR = 10 × weight(kg) + 6.25 × height(cm) - 5 × age(y) + 5
Women: BMR = 10 × weight(kg) + 6.25 × height(cm) - 5 × age(y) - 161
Calculation Process
| Step | Description |
|---|---|
| 1 | Calculate BMR using Mifflin-St Jeor formula |
| 2 | Divide BMR by 24 to get hourly metabolic rate |
| 3 | Multiply chronological age by 0.85 |
| 4 | Add both values for final metabolic age |
