instance for a 25-year old man, with a fat body mass of 17%, lean body mass is equivalent to 83%).
About 60% of the body weight is made up by water: it therefore represents the fundamental
component of every living being and it is necessary to keep us alive.
Women (having normally more adipose tissue than men), have a water percentage of about
55-58%, while men have about 60-62% of it.
The water percentage is greater in childhood (at birth it varies from 70 to 77%), and it decreases
with age (in old people the percentage varies from 45% to 55%) and with the increase of fat
deposits. Obese people have a lower body water percentage than lean people.
Refer to this data to compare the obtained percentage.
Water accomplishes many biological functions:
• it promotes the digestive processes;
• it is a thinner for substances that are important for the organism;
• it removes metabolic wastes;
• it carries oxygen, nutrients, enzymes, hormones and glucose to the cells;
• it is a source of mineral salts;
• it regulates the body temperature.
The human organism excretes every day a given quantity of water, which must be regularly
replaced; a water loss of approximately 10% of the body weight, may put at risk the health
condition. Body weight variations, may occur throughout short (hours), medium (days) or long
(weeks) periods. Small weight variations that take place in a few hours, are completely normal and
are due to water retention, since the extra-cellular water (which includes interstitial fluid, plasma,
lymph and transcellular fluid) is the only compartment subject to such rapid variations. When
a weight reduction occurs in a few days, it is very likely that it affected the total water amount
(distributed by approximately 60% inside the cells - intracellular water - and by approximately
40% outside the cells - extracellular water-) and therefore, it also affected the lean body mass.
To conclude, the fat body mass is subject to variations which can be recorded in weeks.
Therefore, in order to evaluate the progression of one's body composition it is
necessary to keep in mind that:
• a weight reduction by itself, accompanied by an unchanged or even increased
body fat percentage, shows that the body has simply lost water (for instance
after a training session, a sauna or a diet that is limited to rapid weight loss).
• a weight increase accompanied by a decreasing or unchanged body fat
percentage, shows the development of precious muscular mass.
• when weight and body fat decrease at the same time, it means that the diet is
effective and that we are also losing volume.
• when there is a high percentage of fat or a reduced muscular mass, the body
water percentage is always too low.
Warning!
When following a diet, it is necessary to expect a reduction in the fat body mass

and not in the muscular mass.
Examples of body composition
Person 1
Entered data: man, 185 cm tall, 39 years old.
Data calculated by the scale: Weight 105 kg , Bodyfat 30.3%, Bodywater 51%
Analysis of body composition: An overweight body composition results from the table. Let's
study in any case the analysis in deep.
The percentage of lean mass is 69.7% (100%-30.3%). Body fat consists of:
• essential fat => 105 kg x 4%= 4.2 kg
• reserve fat => 105 kg x 12%= 12.6 kg
Total body fat (essential fat + reserve fat) is 4.2+12.6 kg = 16.8 kg, which compared to the total
body weight (105 kg) is equal to 16% (ideal % of fat mass for person 1). The difference between
30.3 % (actual % of fat mass) and 16% (ideal % of fat mass) is 14.3%, which applied to the
total weight (105 kg) is equal to 15 kg.
15 kg represent the kg in defect of person 1. The water percentage of 51% is low compared to
the normal percentage that must have the men but it is due to the high percentage of fat mass
and then a reduced muscular mass.
TIPS FOR USE
• Place the scale on a flat, hard surface.
Soft, uneven flooring (e.g. rugs, carpets, linoleum) can cause the scale to give an uneven
reading of your weight.
• Step onto the scale with your feet parallel and weight equally distributed (see illustrations).
Stand still while the scale measures your weight.
• It is important to weight yourself with dry, bare feet, correctly positioned on the electrodes
(see illustrations). Moreover, for the scale to work properly, avoid your legs touching.
• The scale does not show any danger, since it works with 4 x 1,5V alkaline
batteries.
However, the following people should avoid using it:
- those fitted with a pace-maker or other forms of electronic, medical
- those with a temperature
- children under the age of 10
- pregnant woman
- those in dialysis, with edemas on their legs, people with dimorphism or
- people on cardiovascular medication.
• Always weigh yourself on the same scale every day at the same time, undressed and before
breakfast.
