What Is Metabolic Age?

Metabolic age is a comparison of your Basal Metabolic Rate (BMR) to the average BMR of people of your chronological age. Your BMR represents the minimum number of calories your body needs to perform basic functions while at rest.

If your metabolic age is lower than your actual age, it suggests that your body is in better metabolic health than the average person your age. Conversely, if your metabolic age is higher than your chronological age, it may indicate that improvements in diet, exercise, or other lifestyle factors could benefit your metabolic health.

Why Calculate Your Metabolic Age?

Understanding your metabolic age can provide valuable insights:

How to Improve Your Metabolic Age

If your metabolic age is higher than your chronological age, consider these strategies to improve it:

  1. Increase Muscle Mass: Muscle tissue burns more calories at rest than fat tissue
  2. Regular Exercise: Both cardiovascular and resistance training can boost metabolism
  3. Adequate Protein: Sufficient protein intake helps maintain and build muscle mass
  4. Stay Hydrated: Proper hydration is essential for optimal metabolic function
  5. Quality Sleep: Poor sleep negatively impacts metabolic health
  6. Manage Stress: Chronic stress can disrupt hormonal balance affecting metabolism
  7. Regular Meals: Consistent meal timing can help regulate metabolic processes

How Metabolic Age Is Calculated

The calculation of metabolic age involves several steps:

  1. First, your Basal Metabolic Rate (BMR) is calculated using the Mifflin-St Jeor equation, which takes into account your weight, height, age, and gender
  2. Then, your BMR is compared to a reference table of average BMR values by age and gender
  3. Your metabolic age is the age whose reference BMR most closely matches your calculated BMR

This provides a simple way to understand how your metabolism compares to population averages at different ages.
