BODY WATER -WHY MEASURE IT? Body water is the single most important
component of body weight. It represents over half of your total weight and almost
two thirds of your lean body mass (predominantly muscle). Water performs a
number of important roles in the body: All the cells in the body, whether in the skin,
glands, muscles, brain or anywhere else, can only function properly if they have
enough water. Water also plays a vital part in regulating the body's temperature
balance, particularly through perspiration. The combination of your weight and fat
measurement could appear to be 'normal' but your body hydration level could be
insufficient for healthy living.

For those using Athlete Mode: note that athletes may have a lower body fat range
and a higher body water range than shown above, depending on their type of sport
or activity. Body water measurement results are influenced by the proportion of body
fat and muscle. If the proportion of body fat is high, or the proportion of muscle is
low then the body water results will tend to be low. It is important to remember that
measurements such as body weight, body fat and body water are tools for you to use
as part of your healthy lifestyle. As short term fluctuations are normal, we suggest
you chart your progress over time, rather than focus on a single days reading.
The Body Water % ranges published are for guidance only. Professional
medical guidance should always be sought before embarking on diet and
exercise programmes.
WHY SHOULD I KNOW MY MUSCLE MASS? According to the American College of
Sports Medicine (ASCM), lean muscle mass may decrease by nearly 50 percent
between the ages of 20 and 90. If you don't do anything to replace that loss you're
losing muscle and increasing fat. It is also important to know your muscle mass
% during weight reduction. At rest, the body burns approximately 110 additional

calories for each kilo of muscle gained. Some advantages of gaining muscle mass

WHAT DOES MY BMI VALUE
30.0 - 33.7 ≥33.8
MEAN? Body Mass Index
30.2 - 34.0 ≥34.1
(BMI) is an index of weight-
30.2 - 34.3 ≥34.4
for-height that is commonly
30.9 - 34.7 ≥34.8
used to classify underweight,
overweight and obesity in

adults. This scale calculates
20 - 24.9 ≥25 your BMI value for you. The
BMI categories shown in
22 - 27.9 ≥28
the chart and table below
25 - 29.9 ≥30
are recognised by the WHO
(World Health Organisation)
Moderate High
and can be used to interpret
33 - 38.9 ≥39
your BMI value.
34 - 39.9 ≥40
Your BMI category can be
36 - 41.9 ≥42
identified using the table
below.
BMI Category
18.6-24.9
IMPORTANT: If the chart/table shows that you are outside of a 'normal' healthy
weight range, consult your doctor before taking any action. BMI classifications are for
adults (age 20+ years) only.
BASAL METABOLIC RATE (BMR) - WHAT DOES IT MEAN? Your Basal Metabolic Rate
(BMR) is an estimation of the energy (measured in calories) expended by the body, at
rest, to maintain normal body functions.This continual work makes up about 60-70%
of the calories the body uses, and includes the beating of your heart, respiration, and
the maintenance of body temperature.Your BMR is influenced by a number of factors,
including age, weight, height, gender, dieting and exercise habits.
QUESTIONS & ANSWERS
Optimal BW % Range
How exactly is my body fat and water being measured? This Salter Scale uses
70 to 63%
a measurement method known as Bioelectrical Impedance Analysis (BIA). A minute
current is sent through your body, via your feet and legs. This current flows easily
63 to 57%
through the lean muscular tissue, which has a high fluid content, but not easily
57 to 55%
through fat. Therefore, by measuring your body's impedance (i.e. its resistance to the
55 to 37%
current), the quantity of muscle can be determined. From this, the quantity of fat and
70 to 58%
water can then be estimated.
58 to 52 %
What is the value of the current passing through me when the measurement
52 to 49%
is taken? Is it safe? The current is less than 1mA, which is tiny and perfectly safe.
49 to 37%
You will not be able to feel it. Please note however, that this device should not be
used by anyone with an internal electronic medical device, such as a pacemaker, as a
precaution against disruption to that device.
If I measure my body fat and water at different times during the day, it can
vary quite considerably. Which value is correct? Your body fat percentage
reading varies with body water content, and the latter changes throughout the course
of the day. There is no right or wrong time of the day to take a reading, but aim to
take measurements at a regular time when you consider your body to be normally
hydrated. Avoid taking readings after having a bath or sauna, following intensive
exercise, or within 1-2 hours of drinking in quantity or eating a meal.
My friend has a Body Fat Analyser made by another manufacturer.
When I used it I found that I got a different body fat reading. Why is this?
Different Body Fat Analysers take measurements around different parts of the body
and use different mathematic algorithms to calculate the percentage of body fat.
The best advice is to not make comparisons from one device to another, but to use
the same device each time to monitor any change.
