Introduction
Understanding metabolic age is crucial for assessing one's health in relation to their actual age and metabolism. Metabolic age is calculated based on your Basal Metabolic Rate (BMR) which compares your metabolism to an average for your chronological age group. This value can serve as a motivator or a crucial check for potential health issues. It's calculated by considering your height, weight, gender, and age, factors that influence your daily energy expenditure at rest.
To assess and potentially improve your metabolic health, efficiently calculating your metabolic age can be a critical step. Leveraging advanced tools like Sourcetable can streamline this process. Sourcetable's AI-powered spreadsheet assistant simplifies entering and analyzing health data, aiding in accurate metabolic age calculation.

How to Calculate Metabolic Age
To calculate your metabolic age accurately, you need specific tools and formulas. This guide outlines the essentials for determining your metabolic age and how to use them.
Required Tools
Begin with a Tanita body composition scale, such as the RD-545, BC-401, BC-731, or BC-545N. These scales measure not only weight but also body fat percentage, muscle mass, and other critical data.
Necessary Data Inputs
Input data including your gender, age, height, weight, and body fat percentage into a metabolic age calculator. These figures are crucial as they are used to compute your Basal Metabolic Rate (BMR) and Body Mass Index (BMI).
Formulas Used
Utilize the Harris-Benedict Equation to estimate your BMR. For males, the formula is 66.5 + (13.75 x weight in kg) + (5.003 x height in cm) – (6.775 x age). For females, the formula is 655.1 + (9.563 x weight in kg) + (1.850 x height in cm) – (4.676 x age). Your BMR and BMI derived from these calculations help determine your metabolic age.
Best Practices
For more precise results, follow these best practices: Measure your body composition, waist circumference, and resting blood pressure after fasting. Use special software along with a 5-day diet analysis to support the calculation. Comparing your results with standards for your age group provides a relative metabolic age, which is helpful for personalized assessments.
Additional Considerations
Factors such as hormones, biological sex, muscle mass, and height affect metabolic age. Consulting with a healthcare professional can provide further insights and personalized advice based on these factors.
How to Calculate Metabolic Age
Understanding Metabolic Age
Metabolic age is a comparative age that indicates how your basal metabolic rate (BMR), a measure of how many calories you burn at rest, compares to an average for your chronological age group. It's a useful metric to assess your overall health and fitness levels.
Calculating Basal Metabolic Rate (BMR)
To calculate metabolic age, start by determining your BMR, which relies on your sex, weight, height, and age. Use the following formulas based on biological sex:For men: BMR = 66.5 + (13.75 \times weight\, in\, kg) + (5.003 \times height\, in\, cm) - (6.775 \times age)For women: BMR = 655.1 + (9.563 \times weight\, in\, kg) + (1.850 \times height\, in\, cm) - (4.676 \times age).
Utilizing Metabolic Age Charts
After calculating your BMR, compare it to a metabolic age (MA) chart, which shows average BMR values for different ages and sexes. If your BMR is lower than the average for your age group, your metabolic age is older than your chronological age.
Key Factors Influencing Metabolic Age
Factors such as hormones, muscle mass, and height influence BMR calculations and, subsequently, your metabolic age. Gaining muscle and managing hormonal balance can help improve metabolic age.
Conclusion
Calculating your metabolic age provides insight into your general metabolic health and guides potential lifestyle adjustments. Regularly tracking these metrics can motivate improvements in diet and fitness, contributing to better overall health.

Metabolic Age Calculation Examples
Example 1: Basic BMR Formula
For an initial rough estimate of metabolic age, calculate Basal Metabolic Rate (BMR) using the Harris-Benedict equation. For women: BMR = 655 + (9.6 \times weight) + (1.8 \times height) - (4.7 \times age). For men: BMR = 66 + (13.7 \times weight) + (5 \times height) - (6.8 \times age). Compare this BMR to average BMRs by age to estimate metabolic age.
Example 2: Incorporating Physical Activity
Adjust the BMR based on activity level to get a more accurate estimate. Multiply BMR by 1.2 for sedentary, 1.375 for lightly active, 1.55 for moderately active, 1.725 for very active, or 1.9 for extremely active. This total indicates daily calorie needs, helping pinpoint metabolic age by comparing it against norms for different ages.
Example 3: Using a Metabolic Scale
Scenario: A person weighs 70 kg, is 175 cm tall, and is 30 years old, leading a sedentary lifestyle. Using a metabolic scale that calculates BMR directly, the scale shows a metabolic age of 25. This comparison suggests a younger metabolic age relative to chronological age, indicating better metabolic health.
Example 4: Professional Metabolic Testing
Undergo a professional Resting Metabolic Rate (RMR) test, which uses precise instruments to measure oxygen consumption. RMR differs slightly from BMR by accounting for a more relaxed state. This precise RMR reading can then be analyzed against age group norms to assign a metabolic age.
Example 5: Using Online Calculators
Employ online metabolic age calculators, which require inputs such as age, gender, weight, height, and activity level. These tools use various proprietary formulas to estimate BMR and suggest a metabolic age, providing a quick and convenient method for estimation.
