Getting Accurate Readings

Getting Accurate Readings Step 1Getting Accurate Readings Step 2

To ensure accuracy, readings should be taken without clothing and under consistent conditions of hydration. Always remove your socks or stockings, and be sure the soles of your feet are clean before stepping on the measuring platform. Be sure that the arch of each foot is aligned with the center of the measuring platform. Don't worry if your feet appear too large for the unit, accurate readings can still be obtained if your toes overhang the platform. It is best to take readings at the same time of day. Try to wait about two hours after getting up, eating, or strenuous exercise before taking measurements. While readings taken under other conditions may not have the same absolute values, they are accurate for determining the percentage change as long as the readings are taken in a consistent manner. To monitor your progress, compare your weight and body fat percentage readings taken under the same conditions over a period of time.

Note: An accurate reading will not be possible if the soles of your feet are not clean, if your knees are bent or if you are sitting down.

This Body Composition Monitor product provides readings for informational purposes only.
This product is not intended to diagnose or treat any disease or abnormalities. Please consult your physician if you have any questions or concerns related to your health.

How Does a Body Composition Monitor Work?

TANITA Body Composition Monitors calculate your body composition using Dual Frequency Bioelectrical Impedance Analysis (BIA). Safe, low-level electrical signals are passed through the body via the TANITA foot pads on the platform. The signal can flow easily through fluids in muscles and other body tissue but meets resistance as it passes through body fat, because body fat only contains a small amount of fluid. This resistance is called impedance. The impedance readings are then entered into medically researched mathematical formulas to calculate your body composition.

The TANITA RD-953PRO incorporates medical grade Dual Frequency BIA technology, allowing you to have the highest body composition accuracy in the comfort of your home. Research has shown that using two different bioelectrical impedance frequencies, provides essential data of a person's intracellular and extracelluar status. This advanced technology allows greater accuracy when calculating body composition measurements.

  2. High Frequency Current
  3. Low Frequency Current

When Is the Best Time To Use My Body Composition Monitor?

Your body water levels naturally fluctuate throughout the day and night. Any significant changes in body water may affect your body composition readings. For example, the body tends to be dehydrated after a long night sleep so if you take a reading first thing in the morning your weight will be lower and your body fat percentage higher. Eating large meals, drinking alcohol, menstruation, illness, exercising, and bathing may also cause variations in your hydration levels.
To get the most reliable reading it is important to use your Body Composition Monitor at a consistent time of day under consistent conditions. A good time to take measurements is before your evening meal.

What Is Body Fat Percentage?

Body fat percentage is the amount of body fat as a proportion of your body weight.
Reducing excess levels of body fat has been clinically proven to reduce the risk of certain conditions such as high blood pressure, heart disease, diabetes and cancer.
The chart below shows the healthy ranges of body fat.
Body Fat Ranges for Standard Children 1
Body Fat Ranges for Standard Adults 2,3,4

What Is Body Fat Percentage - FemaleWhat Is Body Fat Percentage - Male

  1. Body Fat Reference Curves for children Targeted at BMJ (British Medical Journal) Draft 1-AMP 19 June 2004 (by Dr Andrew)
  2. Gallagher D et al. Am J Clin Nutr 2000, 72:694-701Healthy percentage body fat ranges: an approach for developing guidelines based on body mass index.
  3. Based on NIH/WHO BMI Guidelines.
  4. As reported by Gallagher, et al, at NY Obesity Research Center.
    To determine the percentage of body fat that is appropriate for your body, consult your physician.

Underfat: Below the healthy body fat range. Increased risk of health problems.
-Healthy •+Healthy: Within the healthy body fat percentage range for your age/gender.
Overfat: Above the healthy range. Increased risk of health problems.
Obese: Far above the healthy body fat range.
Greatly increased risk of obesity-related health problems.

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 ensures the body functions efficiently and reduces 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's sleep 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 be used as a guide and should not be used to specifically determine your 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 body 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 relative changes.
Every individual is different, 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: TANITA 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 function indicates the amount of visceral fat in your body.
Visceral fat is the fat that is in the internal abdominal cavity, surrounding the vital organs in the 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 abdominal 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 provides you with a visceral fat rating from 1 – 59.
Rating 1 - 12
Indicates you have a healthy amount of visceral fat. Continue monitoring your rating to ensure that it stays within this healthy range.
Rating 13 - 59
Indicates you have an excess amount of visceral fat. Consider making changes in your lifestyle by changing your diet or exercising more.
Source: Data from Columbia University (New York) & TANITA Institute (Tokyo)
Note: You may have a high visceral fat level even if you have a low body fat rate.
- Consult a physician for an accurate medical diagnosis.

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 dailychores), 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 maintainyour current weight.

How Does a TANITA Body Composition Monitor Calculate DCI?

The basic way of calculating Basal Metabolic (BMR) Rate 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).*

*Reliability on equation for Basal Metabolic Rate: At 2002 Nutrition Week: A Scientific and Clinical Forum and Exposition Title: International Comparison: Resting Energy Expenditure Prediction Models: The American Journal of Clinical Nutrition.

DCI=BMR x Activity Level
Activity Level

1 2 3
Female 1.56 1.64 1.82
Male 1.55 1.78 2.10

Source: World Health Organization (WHO)

What Is Metabolic Age? (Applicable age 18-99)

This function calculates your BMR and indicates the average age associated with the type of metabolism.
If your metabolic age is higher than your actual age, it is an indication that you need to improve your metabolic rate. Increased exercise builds healthy muscle tissue, which improves your metabolic age.
The reading is shown as a number between 12 and 90. Values under 12 are displayed as "12" and over 90 are displayed as "90".

What Is Muscle Mass? (Applicable age 18-99)

This function indicates the weight of muscle in your body. The muscle mass displayed includes skeletal muscle, smooth muscle (such as cardiac and digestive muscle) and the water contained in these muscles.
Muscles play an important role as they act as an engine that consumes energy. As your muscle mass increases, your energy consumption increases helping you reduce excess body fat levels and lose weight in a healthy way.

What Is Physique Rating? (Applicable age 18-99)

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 also changes accordingly. Even if your weight does not change, your muscle mass and body fat levels may be changing to make you healthier and reduce your risk of certain diseases. Each person should set their own goal of which physique they want to achieve, and follow a diet and fitness program to meet that goal.

What Is Physique Rating

Index of amount of muscle against height = Muscle mass (kg) / height (cm)2

What Is Muscle Quality Score? (Applicable age 18 - 99)

Muscle quality score indicates the "quality (state) of muscle" which changes according to factors such as age and fitness. The muscles of young people or those who exercise regularly is normally in a good state, but the state of muscles deteriorates in elderly people or those who do not get enough exercise. Inner Scan Dual Body Composition Analyzer uses 2 different frequencies to measure Bioelectrical Impedance, these results are used to evaluate intracellularwater(ICW) and extracellular water(ECW) to determine the muscle state using the Muscle Quality Score. Inside muscle fibers, there is protein and water. As muscle fibers grow as a result of strength and conditioning exercise, muscle protein increases and consequently the ICW increases. Through understanding an individual's ICW and ECW, Muscle Quality score can be calculated.

*Muscle Quality Score may not be accurately evaluated if there are abnormalities in the state of body water, such as in the following conditions:
- If the body fatigued or swollen.
- If the person is dehydrated or suffering from reduced blood flow.

It is important to maintain a good balance between muscle mass and quality.

Note:
More ★ indicates a better state of muscle.
