Introduction

Metabolic age is a popular term that’s often used to gauge an individual’s overall health and fitness. It’s calculated by comparing a person’s basal metabolic rate (BMR) with the BMR of an average person in the same age group. The concept behind metabolic age is that it can provide crucial insights into how efficiently our bodies are functioning. So, how is metabolic age calculated? Read on to find out.

Understanding Basal Metabolic Rate (BMR)

BMR refers to the number of calories our body requires to maintain basic, at-rest functions like breathing, blood circulation, and cell production. Each person’s BMR is unique and dependent on factors such as age, weight, height, and gender.

Methods to Calculate Metabolic Age

There are several methods available for calculating metabolic age; however, most revolve around calculating the individual’s BMR first. Here are some of the most common methods:

1. Harris-Benedict Equation: This formula calculates BMR by taking into account a person’s gender, age, height, and weight.

For men: BMR = 88.362 + (13.397 x weight in kg) + (4.799 x height in cm) – (5.677 x age in years)

For women: BMR = 447.593 + (9.247 x weight in kg) + (3.098 x height in cm) – (4.330 x age in years)

2. Mifflin-St Jeor Equation: This equation is another method for estimating BMR that also considers a person’s weight, height, and age.

For men: BMR = (10 x weight in kg) + (6.25 x height in cm) – (5 x age in years) + 5

For women: BMR = (10 x weight in kg) + (6.25 x height in cm) – (5 x age in years) – 161

Calculating Metabolic Age

Once an individual’s BMR is calculated, it’s then compared with the BMR of an average person within the same age group. If a person’s BMR is higher than the average BMR for their age, their metabolic age will be lower, indicating a more efficient and healthy body. Conversely, if a person’s BMR is lower than the average for their age group, their metabolic age will be higher, indicating potential health risks or room for improvement.

Conclusion

Metabolic age can be a useful metric to assess one’s overall health and metabolic function. It provides individuals with valuable insights to improve their lifestyle choices and adopt healthier habits tailored to their unique needs. Remember that although metabolic age can inform us about our current state of health, it should not be considered as the sole indicator; regular check-ups with healthcare professionals are essential for maintaining overall well-being.
