- What is basal metabolic rate (BMR)?
(Applicable age 18 - 99)
What is BMR?
Your Basal Metabolic Rate(BMR) is the minimum level of energy your body needs when at rest to function
effectively including your respiratory and circulatory organs, neural system, liver, kidneys, and other
organs. You burn calories when sleeping.
About 70% of calories consumed every day are used for your basal metabolism. In addition, energy is
used when doing any kind of activity however; the more vigorous the activity is the more calories are
burned. This is because skeletal muscle (which accounts for approximately 40% of your body weight) acts
as your metabolic engine and uses a large amount of energy. Your basal metabolism is greatly affected
by the quantity of muscles you have, therefor increasing your muscle mass will help increase your basal
metabolism.
By studying healthy individuals, scientists have found that as people age, their metabolic rate changes.
Basal metabolism rises as a child matures. After a peak at the age of 16 or 17, it typically starts to decrease
gradually.
Having a higher basal metabolism will increase the number of calories used and help to decrease the
amount of body fat. A low basal metabolic rate will make it harder to lose body fat and overall weight.
How does a Tanita body composition analyzer caluclate BMR?
The basic way of calculating Basal Metabolic Rate BMR is a standard equation using weight and age.
Tanita has conducted in-depth research into the relationship of BMR and body composition giving a much
more accurate and personalized reading for the user based on the impedance measurement. This method
has been medically validated using indirect calorimetry (measuring the breath composition).*

- What is metaboric age?
(Applicable age 18–99)
This feature calculates your BMR and indicates the average age associated with that type of metabolism.
If your BMR Age is higher than your actual age, it is an indication that you need to improve your
metabolic rate.
Increased exercise will build healthy muscle tissue, which will improve your metabolic age.
You will obtain a reading between 12 and 90. Under 12 will be displayed as “12” and over 90 displayed
as “90”.
