Understanding Measurements

Understanding your measurements

Underfat : below the healthy body fat range. Increased risk for health problems.
Healthy : within the healthy body fat percentage range for your age/gender.
Overfat : above the healthy range. Increased risk for health problems.
Obese : high above the healthy body fat range. Greatly increased risk of obesity-related health problems.

Note: Athletes may have a lower body fat range depending on their particular sport or activity.

What is body fat percentage? (Applicable age 5 - 99)


Body fat percentage is the amount of body fat as a proportion of your body weight. Reducing excess levels of body fat has shown to reduce the risk of certain conditions such as high blood pressure, heart disease,diabetes and cancer. The chart below shows the healthy ranges for body fat

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 apercentage 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 longterm 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 my reduce the risk of certain diseases such as heart disease, high blood pressure, and the onset of type 2 diabetes. The Tanita Body Composition Analyzer 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, 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 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? (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”.


What is muscle mass? (Applicable age 18 - 99)

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 bone mass? (Applicable age 18 - 99)


This feature indicates the amount of bone (bone mineral level, calcium or other minerals) in the body. Research has shown that exercise and the development of muscle tissue are related to stronger, healthier bones. While bone structure is unlikely to make noticeable changes in a short period, it is important that you develop and maintain healthy bones by having a balanced diet and plenty of exercise. People worried about bone disease should consult their physician. People who suffer from osteoporosis or low bone densities due to advanced age, young age, pregnancy,hormonal treatment or other causes, may not get accurate estimations of their bone mass. Below is the result of estimated bone masses of persons aged 20 to 40, who are said to have the largest amounts of bone masses, by weight. (Source : Tanita Body Weight Science Institute)
Please use the below charts as a guide to compare your bone mass reading.

 

Note: Persons described below may obtain varying readings and should take the values given for reference purposes only.
- Elderly persons
- Women during or after menopause
- People receiving hormone therapy

“Estimated bone mass” is a value estimated statistically based on its correlation with the fat-free amount (tissues other than the fat). “Estimated bone mass” does not give a direct judgment on the hardness or strength of the bones or the risks of bone fractures. If you have concerns over your bones, you are recommended to consult a specialist physician.

Physique Rating

This feature assesses your physique according to the ratio of body fat and 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 maybe be changing making you healthier and at lower risk of certain deseases. Each person should set their own goal of which physique they would like and follow a diet and fitness programe to meet that goal.

Athlede mode

Tanita developed a specific ‘Athlete’ mode for its monitors that are calibrated against a representative sample of athletes. As a general guideline, we recommend Athlete mode for anyone who carries out more than 10 hours of intensive aerobic exercise a week, has been doing so for at least six months AND who has a resting heartbeat of under 60bpm. Athlete mode can also be applied to people who have a lifetime history of fitness - who used to do more than 10 hours a week - but do less now
