New electronic personal scale allowing the detection of the basal metabolic rate and of the body
composition (percentage of fat and water) according to the height, age, gender. The exact knowledge
of your body composition (calculation of lean body mass, fat body mass and total body water
contents), allows a correct estimate of the excess fat and at the same time determines the advisable
weight as a function of your nutritional condition. Furthermore, the knowledge of your body
composition allows to combine a correct nutrition and physical activity as essential conditions to
improve the quality of life, promote health and prevent pathologies. It has a memory function with
a 4-person capacity.
Capacity 150 kilos, divided into 100 grams.

BODY COMPOSITION
It is important to know the body composition of an individual in order to be able to estimate his/
her health condition.
Actually, it is not enough to know one’s weight but it is necessary to define its quality, which means
dividing the human body in its two major component masses:
• leanbodymass:bones,muscles,viscera,water,organs,blood;
• fatbodymass:adiposecells.
Under the same conditions of weight, these two masses have different volumes.
By means of electrodes placed on the platform, the scale sends a weak low intensity electric current
that passes through the body mass.
The electric current reacts in a different way according to the masses it passes through: the lean body
mass opposes a weak resistance, while the fat body mass has a greater resistance.
This body resistance, called bioelectrical impedance, varies also in function of sex, age and height. For
a correct control of your healthy weight, besides the weight, it is important to compare the percentage
of fat calculated by the scale with the parameters quoted in the table, as well as to assess your own
percentage of water and basal metabolic rate using the information provided here below.
Should the percentages be outside the normal values, it is suggested you refer to
yourowndoctor.
It is suggested to take note of these values for a given period of time in order to
understandthembetter.
In order to obtain a valid comparison, you should weigh yourself always at the same time of the
day and under the same conditions. The best moment to weigh yourself is in the morning, before
breakfast, without clothes.
You have to wait 15 minutes after getting up, so that the water can distribute itself throughout the
body.
Bodyfatmasspercentage
The percentage of fat listed in the following table, represents the total fat, calculated by summing up
the essential fat (or primary fat) and the spare fat (or storage fat).
The essential fat is necessary since it is needed for the metabolism. The percentage of this fat is
different between the two sexes: about 4% for men and about 12% for women (percentage calculated
on the total body weight).
The spare fat, which is theoretically superfluous, is necessary in a minimum quantity for a healthy
condition, especially for those who carry out physical activities.
Even in this case, the fat percentage is different between the two sexes: 12% for men, 15% for women
(percentage calculated on the total body weight).
Therefore, the normal percentage of fat mass on the body weight is approximately 16% for men and
27% for women. Such percentages differ with the person’s age as shown in the table here below.
Waterpercentage
Water is the main component of lean body mass; the water percentage over the fat body mass is 73%.
The lean body mass is obtained by subtracting from the total weight the fat body mass (for 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
necessarytokeepinmindthat:
- a weight reduction by itself, accompanied by an unchanged or even increased
bodyfat percentage,shows thatthebody hassimply lostwater (forinstance after
atrainingsession,asaunaoradietthatislimitedtorapidweightloss).
- a weight increase accompanied by adecreasing or unchanged body fat percentage,

Basalmetabolicrate
The basal metabolic rate (BMR) is the minimum quantity of calories necessary for the human body to
survive, i.e. to carry out basic processes such as the circulation, respiration, digestion, preservation
of body temperature.
The basal metabolic rate is calculated on a person mentally and physically resting in supine position,
not eating for 12 hours, after at least 8 hours of sleep and at a constant room temperature of about
20°C. The basal metabolic rate for the adults ranges between 1200 and 1800 kcal.
The BMR is influenced by various factors:
• age: it is higher when one is young; with the increase of age, the muscular mass decreases and
consequently the BMR, too.
• gender: the BMR is greater in men due to the testosterone and of the greater muscular mass.
• height: the BMR is greater in tall and slim people.
• body composition: the increase of the muscular mass involves an increase of the BMR; the
increase of the fat mass involves a decrease of the BMR.
• fever/stress: the BMR increases in case of stress or of fever.
• nutrition state: the fasting, poor nutrition or malnutrition decrease the BMR; while high protein
diets increase the BMR.
• climate: with very high or very low environment temperatures, the BMR increases.
• thyroxin: thyroxin is a hormone produced by the thyroid; this hormone has among its functions
that of adjusting the metabolism intensity. More thyroxin is produced and greater is the BMR.
Considering this information, the basal metabolic rate allows monitoring the
number of calories required by the body according to the physical state and to the
life-style.
The greater is the muscular mass or the greater is the physical activity, more are the required calories:
it is essential to know such information to optimize a diet or physical activity.
Exampleofbodycomposition
Person1
Input Data: female, 162 cm tall, 30 years old.
Data calculated by the scale: Weight 61.7 kilos, Bodyfat 28.5%, Bodywater 52.1%, Basal metabolic
rate 1381 kcal.
Analysis of body composition: According to the table the body composition is normal. Let’s analyze
it in details.
The percentage of lean body mass is 71.5% (100% - 28.5)
The water percentage is 52.2% (71.5% x 73%).
The body fat is made up as follows:
• essentialfat=>61.7kilosx12%=7.4kilos
• sparefat=>61.7kilosx15%=9.3kilos
The total body fat (essential fat + spare fat) is made up of 7.4 + 9.3 kilos = 16.7 kilos that over the
total of body weight (61.7 kilos) is equivalent to 27% (ideal percentage of fat mass for person 1).
The difference between 28.5% (fat body mass actual percentage) and 27% (fat body mass ideal
percentage) is 1.5%, which applied to the total weight of 61.7 kilos is equivalent to 0.93 kilos.
0.93 kilos represent the excess weight of person 1.
A water percentage of 52.1% is a little low compared to the normal percentage for women but it is
due to a higher fat body mass percentage and therefore to a reduced muscular mass.
The basal metabolic rate is 1381 kcal and it is influenced by the gender, weight and height (woman,
normal body composition, therefore BMR tending to 1200 kcal).
