What Is Total Body Water Percentage; What Is Basal Metabolic Rate (Bmr) - Tanita TBF-300WA plus Instruction Manual

- What is total body water percentage?

Total Body Water Percentage is the total amount of fluid in a person's body expressed as a percentage
of their total weight.
Water plays a vital role in many of the body's processes and is found in every cell, tissue and organ.
Maintaining a healthy total body water percentage will ensure the body functions efficiently and will
reduce the risk of developing associated health problems.
Your body water levels naturally fluctuate throughout the day and night. Your body tends to be
dehydrated after a long night and there are differences in fluid distribution between day and night. Eating
large meals, drinking alcohol, menstruation, illness, exercising, and bathing may cause variations in your
hydration levels.
Your body water percentage reading should act as a guide and should not be used to specifically
determine your absolute recommended total body water percentage. It is important to look for long-term
changes in total body water percentage and maintain a consistent, healthy total body water percentage.
Drinking a large quantity of water in one sitting will not instantly change your water level. In fact, it will
increase your body fat reading due to the additional weight gain. Please monitor all readings over time to
track the relative change.
Every individual varies but as a guide the average total body water percentage ranges for a healthy adult are:
Female: 45 to 60%
50 to 65%
Male:
Source: Based on Tanita's Internal Research
Note: The total body water percentage will tend to decrease as the percentage of body fat increases. A
person with a high percentage of body fat may fall below the average body water percentage. As you lose
body fat the total body water percentage should gradually move towards the typical range given above.

- 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 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).*
