- What is basal metabolic rate (BMR)?
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 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 metabolic age?
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 50. Under 12 will be displayed as "12" and over 50 displayed
as "50".

- What is mascle mass?
This feature indicates the weight of muscle in your body. the muscle mass displayed includes the skeletal
muscles, smooth muscles (such as cardiac and digestive muscles) and the water contained in these
muscles.
Muscles play an important role as they act as an engine in consuming energy. As your muscle mass
increase, your energy consumption increases helping you reduce excess body fat levels and lose weight
in a healthy way.
- What is physique rating?
This feature assesses your physique according to the ratio of body fat ad muscle mass in your body.
As you become more active and reduce the amount of body fat, your physique rating will also change
accordingly. Even though your weight may not change, your muscle mass and body fat levels may be
changing making you healthier and at lower risk of certain diseases.
Each person should set their own goal of which physique they would like and follow a diet and fitness
program to meet that goal.
