WHAT IS TOTAL BODY WATER PERCENTAGE?

(Applicable age 18-99)
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%
Male : 50 to 65%
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 VISCERAL FAT RATING?

(Applicable age 18-99)
This feature indicates the rating of visceral fat in your body.
Visceral fat is the fat that is in the internal abdominal cavity, surrounding the vital organs in the trunk (abdominal) area. Research
shows that even if your weight and body fat remains constant, as you get older the distribution of fat changes and is more likely to
shift to the trunk area especially post menopause. Ensuring you, have healthy levels of visceral fat may reduce the risk of certain
diseases such as heart disease, high blood pressure, and the onset of type 2 diabetes.
The Tanita Body Composition Monitor will provide you with a visceral fat rating from 1 – 59.
Rating from 1 to 12
Indicates you have a healthy level of visceral fat. Continue monitoring your rating to ensure that it stays within the healthy range.
Rating from 13 – 59
Indicates you have an excess level of visceral fat. Consider making changes in your lifestyle possibly through diet changes or
increasing exercise.

Note:
・Even if you have a low body fat rate, you may have a high visceral fat level.
・For medical diagnosis, consult a physician.

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 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).*

The American Journal of Clinical Nutrition.
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".
