How to Calculate Metabolic Age: A Step-by-Step Guide


What if I said your biological age isn’t the same as your years? That’s where metabolic age comes in.

Knowing yours can help you understand your health and fitness.  Metabolic age measures how well your body’s metabolism works compared to others your age.

It looks at things like muscle mass, body composition, and resting metabolic rate, and gives a more accurate view of how your body’s doing. To calculate, you can use bioelectrical impedance analysis (BIA).

Well, take Sara, who at 40 had a metabolic age of 55. She decided to improve her health by building muscle and changing her diet. After 6 months, her metabolic age dropped to 45! 

So don’t let numbers define you. Take charge of your health and work towards improving it.

Stay tuned for tips on healthy metabolism and well-being.

What is Metabolic Age?

body womanMetabolic age is not linked to your chronological age, but it is a way to assess your metabolism. This involves body composition, muscle mass, and general health.

Knowing yours can help you make the right lifestyle changes. Physical activity, a healthy diet, and adequate sleep all have an impact.

Doing exercise like weight lifting or resistance training can build your muscle mass and thus, increase your metabolism. Eating nutrient-dense foods is also important.

To get the most accurate metabolic age reading, consult a healthcare professional. They can do body composition analysis, resting metabolic rate evaluation, and any other tests that are specific to you.

You can influence your metabolic age by making positive changes. HIIT (High-Intensity Interval Training) can improve metabolic function. Also, focus on eating whole foods such as lean proteins, fruits, vegetables, and whole grains.

Cutting down on processed food high in added sugars and unhealthy fats is also beneficial. Lastly, stay hydrated!

Why is it Important?

Metabolism DictionaryMetabolic age is a vital sign of your overall health and fitness. It shows how efficiently your body processes energy and can reveal potential health risks.

Knowing yours lets you make informed decisions to boost your well-being. As we age, our metabolism slows down.

If our metabolic age is:

  • Higher than our true age, this may signify underlying health issues and an increased risk for illnesses such as diabetes, heart disease, and obesity. 
  • Lower than our true age, this shows a more effective metabolism and good health.

Knowing your metabolic age can also help you customize your diet and exercise plan to meet your particular needs. By focusing on improving your metabolism, you can maximize weight-loss efforts, increase energy levels, and increase overall vitality.

Calculating yours requires considering factors like weight, height, gender, body composition (including muscle mass and fat percentage), and activity level. There are online calculators and health professionals who can help you find out yours accurately.

How to Calculate Metabolic Age

To calculate, follow the steps outlined below:

Step 1: Gather the Required Information

  1. Measure your height. Use a tape measure and stand straight. Don’t round off any measurements.
  2. Weigh yourself. Use a reliable scale to measure your weight in kg or lbs. You need to ensure an accurate weight measurement for calculating.
  3. Calculate your body fat percentage. Use methods like BIA, skinfold calipers, or DEXA scans
  4. Assess your physical activity level. Think about exercise, a sedentary lifestyle, and job requirements.
  5. Your Age and Gender also play an important role

Further, consider any other unique aspects that are specific to you.

Interesting Fact: Dr. Tamsin Lewis popularized the concept of metabolic age and highlighted the importance of understanding metabolic health. She introduced the metabolism age as a way to assess overall health and fitness.

Step 2: Calculate Basal Metabolic Rate (BMR)

Calculating Basal Metabolic Rate [BMR]

  1. BMR varies between Males and females.
  2. If working in imperial:
    1. Change your weight from pounds to kilograms.
    2. Change your height from inches to centimeters. 
  3. Calculate your age in years

With the above parameters, use the formulas below for BMR:

– For males: BMR = 66 + (13.75 × weight in kg) + (5 × height in cm) – (6.75 × age in years)

– For females: BMR = 655 + (9.56 × weight in kg) + (1.85 × height in cm) – (4.68 × age in years)

Remember, the numbers you get from these formulas are only estimates.

Also, remember that muscle mass, body composition, and activity level can change your metabolism. You may need to adjust the calculations based on these factors.

Step 3: Calculate Metabolic Age

Metabolism RepresentationFather Time doesn’t need to know how old your metabolism feels. Follow these simple steps to calculate yours:

  1. Estimate your BMR. This is the number of calories your body needs to work at rest. Use a calculator or formula based on age, gender, weight, and height.
  2. Measure your body composition. Do this by looking at your body fat percentage and comparing it to the average for your age group. You can use skinfold calipers or a bioelectrical impedance device.
  3. Calculate your metabolic age. Do this by using an online calculator or comparing your BMR and body fat percentage to reference values for different age groups. It will tell you how well your metabolism works compared to others.

Remember, metabolic age is just one piece of the puzzle. It helps you understand how your body processes energy but shouldn’t be the sole determinant of health status.

Factors Affecting Metabolic Age

Metabolic age can be affected by many factors, such as genetics, body composition, physical activity, and overall health. To show the impact of these factors, here’s a table:

Factors Description
Genetics Genes may affect metabolism & metabolic age
Body Composition Muscles mass to fat mass ratio affects metabolism & metabolic age.
