18 years of age (see page 12 for explanation).

WEIGHING/ESTIMATING BODY FAT/BODY WATER

Step on the scale in bare feet, placing each foot directly over the

12 ELECTRODES with the heels and balls of your feet. The LCD DISPLAY

will show your weight for approximately 2 seconds. Stay on the scale.

The scale then begins to estimate your percentage of Body Fat, Total Body

Water, Muscle Mass and Bone Mass. The LCD DISPLAY will show each

estimation in order while computing.

A “beep” tone sounds when the computing is done. Continue to stay on the

scale and the percentage of Body Fat, Total Body Water, Muscle Mass and

Bone Mass will be displayed for 2 seconds sequentially a total of 3 times.

SETTING THE MEMORY

This scale has the memory capacity for 4 users. This will allow 4 people to store

IMPORTANT INFORMATION TO KNOW BEFORE USING YOUR BODY FAT SCALE

Why is it important to monitor percentage body fat (%BF)?

The absolute weight traditionally determines whether or not a person is obese.

Weight change in itself does not indicate whether it was the weight of body fat or

muscle that had changed. In weight management, it is desirable that muscle mass

be maintained while body fat is lost. Thus, monitoring the percentage fat of the

body is an important step toward successful weight management and body health.

The optimal %BF of an individual varies according to age and gender.

The table as follows may be used as a guide:

Standard for Men

Moderate 29-31 30-32 31-33 32-33 33-35

High > 31 >32 >33 >34 >35

How is percentage body fat (%BF) estimated?

% of BF is estimated by a method called Bioelectrical Impedance Analysis (BIA).

The use of BIA to estimate body fat has been used since the seventies. It was

only in the past decade that the estimation of body fat using BIA technology

was successfully offered to the consumers in a compact bathroom scale.

With the BIA technology, a low intensity electrical signal is sent through the body.

The signal is very low and causes no bodily harm. Depending on the amount of

body fat of the individual, the electrical signal will flow with a different degree of

difficulty. The difficulty with which a signal flows through the body is called electrical

impedance. By measuring the electrical impedance and applying to the data a

proprietary algorithm, %BF can be estimated.

Note: The %BF estimated with this scale represents only an approximation

of your actual body fat. Clinical methods of estimating body fat can also be

ordered by your physician.

Why is it important to monitor percentage Total Body Water (%TBW) in the body?

Water is an essential component of the body and its level is one of the health indicators.

Water makes up approximately between 50-70% of the body’s weight. It is present

proportionally more in lean tissue compared to fat tissue. Water is a medium for

biochemical reactions that regulate body functions. Waste products are carried in

water from cells for excretion in urine and sweat. Water provides form to cells; helps to

maintain body temperature; provides moisture to skin and mucosa; cushions vital organs;

lubricates joints and is a component of many body fluids. The amount of water in the

body fluctuates with the hydration level of the body and state of health.

Monitoring the level of body water can be a useful tool for one’s health maintenance.

Similar to body fat estimation, the %TBW function provided in this scale is based on

BIA.The estimated %TBW may vary according to your hydration level, that is, how

much water you have drunk or how much you have sweated immediately prior to

the estimation. For better accuracy, avoid fluctuation in hydration level prior to the

estimation. The accuracy of the scale in estimating TBW will also decrease with

individuals suffering from diseases that tend to accumulate water in the body.

The optimal %TBW of an individual varies according to age and gender. The table

as follows may be used as a guide: (Source: University of Illinois Medical Center,

Chicago, IL USA)

%BF Range Optimal %TBW Range

4 to 14% 70 to 63%

Men 15 to 21% 63 to 57%

22 to 24% 57 to 55%

25 and over 55 to 37%

4 to 20% 70 to 58%

Women 21 to 29% 58 to 52%

30 to 32% 52 to 49%

33 and over 49 to 37%

IMPORTANT: Please note that the %TBW estimated with the scale

represents only a good approximation of your TBW. Clinical methods

of estimating total body water can also be ordered by your physician.When

should I use the scale’s body fat and total body water functions?

For maximum accuracy and repeatability, it is recommended that the scale’s body

fat and total body water functions be used at approximately the same time of the

day, e.g. before breakfast in the morning. It is also a good practice to avoid swings

in hydration level of the body prior to the estimation. Establishing your own baseline

value of %BF and %TBW and track their changes is better than merely comparing

your %BF and %TBW value to the population’s “normal” value.

Why is the Athlete Mode necessary in a Body Fat Analyzer?

It has been found that body fat estimation using BIA could overestimate the

percentage body fat of adult elite athletes. The physiological variation of athletes in

bone density and level of hydration are two of the reasons said to account for the

difference. The Athlete mode is selectable only for adults of 18 years of age or older.

Definition of an Athlete

The general consensus among researchers is that a quantitative dimension could

be used in defining an athlete. For example, an athlete could be defined as a person

who consistently trains a minimum of three times per week for two hours each time,

in order to improve specific skills required in the performance of their specific sport

and/or activity.

What is Muscle Mass?

The scale estimates the weight of Skeletal Muscle Mass in your body. You’ve got

around 650 muscles in your body, and they make up roughly half of your body weight.

These muscles can be divided into three different groups: Skeletal, Smooth and

Cardiac. All of these muscles can stretch and contract, but they perform very

different functions.

Skeletal muscle: Produces movement, maintains posture, stabilizes joints

and generates heat

Smooth muscle: Found in the walls of hollow organs

Cardiac muscle: Exists only in your heart

Skeletal muscle

The tissue most commonly thought of as muscle is skeletal muscle. Skeletal muscles

cover your skeleton, giving your body its shape. They are attached to your skeleton by

strong, springy tendons or are directly connected to rough patches of bone. Skeletal

muscles are under voluntary control, which means you consciously control what they

do. Just about all body movement, from walking to nodding your head, is caused

by skeletal muscle contraction. Your skeletal muscles function almost continuously

to maintain your posture, making one tiny adjustment after another to keep your

body upright. Skeletal muscle is also important for holding your bones in the correct

position and prevents your joints from dislocating. Some skeletal muscles in your face

are directly attached to your skin. The slightest contraction of one of these muscles

changes your facial expression. Skeletal muscle generates heat as a by-product of

muscle activity. This heat is vital for maintaining your normal body temperature.

Skeletal muscle represents approximately 30% of body weight of a healthy

127lb woman or 40% of a 154lb man. (International Commission on Radiological

Protection, 1975)

What is Bone Mass?

The scale estimates the weight of non-living bone mineral content. This is important

for monitoring and maintaining healthy bones through exercise and a calcium-rich diet.

An adult skeleton is made up of 206 bones, which come in several different shapes

and sizes and have specific structure. Your bones contain blood vessels, nerve cells

and living bone cells known as osteocytes. These are held together by a framework

of hard, non-living material containing calcium and phosphorous. A thin membrane

called the periosteum covers the surface of your bones.

Bone Mineral Content differs according to age and sex. For Adults: The average

bone mineral content of 15-29 year old female is approximately 6lb, that for

15-29 year old male is approximately between 6 and 7.75lb. (Rico et al. 1993)

For Children: The average bone mineral content of 8-16 year old child is

approximately between 1.7 and 4.85lb. (Faulkner et al. 1993)
