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 is 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, therefore 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 MONITOR CALCULATE 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 DAILY CALORIE INTAKE (DCI)?
(Applicable age 18-99)
“Daily Calorie Intake (DCI)” is the sum of calories for basal metabolism, daily activity metabolism (activities including daily
household chores), and diet-induced thermogenesis (energy used in connection with digestion, absorption, metabolism, and other
eating activities). It is an estimate of how many calories you can consume within the next 24 hours to maintain your current weight.

WHAT IS METABOLIC AGE?
(Applicable age 18-99)
This feature calculates your BMR and indicates the average age associated with the 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”.
