Your metabolic age is a comparison between your Basal Metabolic Rate (BMR) and the average BMR for your chronological age group. If your metabolic age is lower than your actual age, your metabolism is performing better than average for someone your age \u2014 a sign of good metabolic health. If it is higher, your metabolism may be slower than expected, which could indicate room for improvement in diet, exercise, or body composition.<\/p>\n\n

Track how your body compares to others in your age group using our Metabolic Age Calculator<\/a> to see where you stand.<\/p>\n\n

How Metabolic Age Is Calculated<\/h2>\n\n

Metabolic age is derived from your Basal Metabolic Rate \u2014 the number of calories your body burns at complete rest just to keep vital organs functioning (heart, lungs, brain). Here is how the calculation works:<\/p>\n\n

  1. Calculate your BMR<\/strong> using the Mifflin-St Jeor equation (most accurate for the general population):
    Men: BMR = 10 \u00d7 weight(kg) + 6.25 \u00d7 height(cm) \u2212 5 \u00d7 age(y) + 5
    Women: BMR = 10 \u00d7 weight(kg) + 6.25 \u00d7 height(cm) \u2212 5 \u00d7 age(y) \u2212 161<\/li>
  2. Compare to population averages<\/strong>: Your BMR is compared to the average BMR for people of your sex and chronological age<\/li>
  3. Result<\/strong>: If your BMR equals the average for a 30-year-old but you are 40, your metabolic age is 30<\/li><\/ol>\n\n
