Metabolic Age Calculation

📌What is Basal Metabolic Rate?

Basal Metabolic Rate (BMR) refers to the minimum amount of calories your body burns while completely at rest—without engaging in any physical activity—solely to maintain vital functions. This includes activities such as heartbeat, breathing, and cell repair. BMR is important not only for sustaining essential bodily functions but also for maintaining a healthy lifestyle, including weight management.

📌What is Metabolic Age?

Metabolic age is a measurement that indicates which average age level your Basal Metabolic Rate corresponds to. The resulting metabolic value helps you understand how your body functions biologically and whether your metabolic rate is appropriate for your chronological age.

📌Why is Knowing Your Metabolic Age Important?

A slowdown in metabolic rate with aging is considered natural. However, many factors independent of age—such as physical inactivity, disrupted sleep patterns, or unhealthy eating habits—can also slow down metabolism, leading to an increase in metabolic age. Therefore, metabolic age can also be an indicator of healthy lifestyle habits. For example, someone who exercises regularly and eats a balanced diet may have a metabolic age lower than their actual age.

📌Calculate Your Metabolic Age Now

By entering your height, weight, age, gender, and daily physical activity level, you can learn both your Basal Metabolic Rate and your Metabolic Age in seconds. Get to know your body better for a healthier life!

There is no standard, universally agreed formula for calculating metabolic age; however, it can be estimated based on your Basal Metabolic Rate (BMR). Most approaches determine metabolic age by comparing it with an ideal reference BMR value.

📌 How is Metabolic Age Calculated?

Metabolic age is determined by comparing your BMR to an average BMR value for your age group.

🔹 Step 1: Calculate BMR

The Mifflin-St Jeor formula is used for BMR calculation:

🔹 For men:

BMR = 66.47 + (13.75 × Weight) + (5 × Height) − (6.76 × Age)

🔹 For women:

BMR = 655.10 + (9.56 × Weight) + (1.85 × Height) − (4.68 × Age)

🔹 Step 2: Compare with Reference BMR Values

Your BMR value is compared with average BMR values by age. In general:

Metabolic age is estimated using the formula:

Metabolic Age = (Reference BMR / Your BMR) × Your Actual Age
