Calculate your metabolic age by comparing your Basal Metabolic Rate (BMR) to global age-group averages. Optimize your metabolism and biological energy output.
The Concept of Metabolic Aging
Your metabolic age is a comparison of your Basal Metabolic Rate (BMR) against the average BMR for your chronological age group. BMR is the number of calories your body burns at rest to maintain vital functions. A lower metabolic age indicates a more 'efficient' body, typically correlated with higher muscle mass and better endocrine health.
The Mifflin-St Jeor Mathematical Standard
PrecisionAge uses the Mifflin-St Jeor formula, the most accurate clinical equation for estimating human energy expenditure. To find your metabolic age calculator free result, we determine your BMR and compare it to the standard decay curve of human metabolism. If your body requires more energy for maintenance than the average 30-year-old, your metabolic age may be recorded in the 20s.
1. Body Composition Impact
Muscle is metabolically active tissue. People with higher lean mass have a 'younger' metabolism. This body age calculator emphasizes the importance of body composition over simple weight.
Frequently Asked Questions
Why is my metabolic age so high?
A metabolic age calculator female or male result that is higher than your birth age often suggests a loss of lean muscle mass or a sedentary lifestyle.
Can I change my metabolic age?
By increasing resistance training and protein intake, you can boost your BMR and lower your metabolic age significantly.
