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.

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.

medical guidance should always be sought before embarking on diet and

WHAT DOES MY BMI VALUE
MEAN?
Moderate High
Body Mass Index (BMI) is an
23.1 - 26.1 ≥26.2
index of weight-for-height
24.6 - 27.9 ≥28.0
that is commonly used to
26.1 - 29.6 ≥29.7
classify underweight,
27.3 - 31.1 ≥31.2
overweight and obesity in
28.3 - 32.1 ≥32.2
adults. This scale calculates
28.9 - 32.7 ≥32.8 your BMI value for you. The
BMI categories shown in
29.2 - 33.0 ≥33.1
the chart and table below
29.5 - 33.2 ≥33.3
are recognised by the WHO
29.7 - 33.5 ≥33.6
(World Health Organisation)
30.0 - 33.7 ≥33.8
and can be used to interpret
30.2 - 34.0 ≥34.1
your BMI value.
30.2 - 34.3 ≥34.4
Your BMI category can be
30.9 - 34.7 ≥34.8
identified using the table
below.
Moderate High
BMI Category
20 - 24.9 ≥25
22 - 27.9 ≥28
18.6-24.9
25 - 29.9 ≥30
Moderate High
IMPORTANT: If the chart/table shows that you are outside of a 'normal' healthy
33 - 38.9 ≥39
weight range, consult your doctor before taking any action. BMI classifications are for
34 - 39.9 ≥40
adults (age 20+ years) only.
36 - 41.9 ≥42
QUESTIONS & ANSWERS
How exactly is my body fat and water being measured?
This Salter Scale uses 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 through the lean muscular tissue, which has a high fluid
content, but not easily through fat. Therefore, by measuring your body's impedance
(i.e. its resistance to the current), the quantity of muscle can be determined. From
this, the quantity of fat and water can then be estimated.
What is the value of the current passing through me when the measurement is
taken? Is it safe?
The current is less than 1mA, which is tiny and perfectly safe. 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
Optimal BW % Range
your body to be normally hydrated. Avoid taking readings after having a bath or
70 to 63%
sauna, following intensive exercise, or within 1-2 hours of drinking in quantity or
63 to 57% eating a meal.
57 to 55% 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?
55 to 37%
Different Body Fat Analysers take measurements around different parts of the body
70 to 58%
and use different mathematic algorithms to calculate the percentage of body fat.
58 to 52 %
The best advice is to not make comparisons from one device to another, but to use
52 to 49%
the same device each time to monitor any change.
49 to 37%
How do I interpret my body fat and water percentage readings?
Please refer to the Body Fat and Water tables included with the product. They will
guide you as to whether your body fat and water reading falls into a healthy category
(relative to your age and sex).
What should I do if my body fat reading is very 'high?
A sensible diet, fluid intake and exercise program can reduce your body fat
percentage. Professional medical guidance should always be sought before
embarking on such a program.
Why are the body fat percentage ranges for men and women so different?
Women naturally carry a higher percentage of fat than men, because the make-up of
the body is different being geared towards pregnancy, breastfeeding etc.
What should I do if my water percentage reading is 'low'?
Ensure that you are regularly taking sufficient water and work towards moving your
fat percentage into the healthy range.
Why should I avoid using the Body Analyser Scale whilst pregnant?
During pregnancy a woman's body composition changes considerably in order to
