What This Calculator Does
The Metabolic Age Calculator compares your Basal Metabolic Rate to average BMR values for your age group. If your metabolic age is higher than your actual age, your metabolism is slower than average.
How It Works
Your BMR is calculated using the Mifflin-St Jeor equation. It is then compared to average BMR values for your age group. A lower metabolic age than chronological age indicates a faster metabolism.
Example
A 35-year-old with a BMR of 1,650 kcal might have a metabolic age of 30, indicating a faster-than-average metabolism for their age group.
Formula
BMR = 10W + 6.25H - 5A + 5 (male)Reading the Results
Your BMR
Your Basal Metabolic Rate. Compare to age-group averages: a lower BMR than average means higher metabolic age.
Frequently Asked Questions
What is metabolic age?
It compares your BMR to average BMR values for your age group. A lower number than your real age means a faster metabolism.
How can I lower my metabolic age?
Build muscle through resistance training, eat adequate protein, and stay active throughout the day.
Is metabolic age accurate?
It is a useful estimate but not a precise measurement. Individual metabolism varies based on genetics, muscle mass, and other factors.
