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:
• lean body mass: bones, muscles, viscera, water, organs, blood;
• fat body mass: adipose cells.
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 re
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, skeletal musculature and
basal metabolic rate using the information provided here below.

doctor.
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.

%ofskeletalmusculature
The muscles are the motors of the skeleton and through the energy they give off during contraction, they let
us move, perform and control movements of the head, body and upper and lower limbs. There are three different
types of muscular tissue: smooth, striated skeletal and striated cardiac.
The striated cardiac muscle is the heart. It is the only organ formed of striated fibre, which involuntarily
contracts.
Smooth muscles are formed of smooth fibres, which are only found in the digestive tract, the respiratory tract
and the genitals, in the walls of the venous and arterial blood vessels.
Smooth muscular tissue is not voluntarily controlled. Striated skeletal muscular tissue, also called voluntary
because it contracts according to our will, forms the skeletal and facial muscles in humans. The job of striated
voluntary muscles is to move the skeleton, allowing us to move and communicate with our surroundings. This
scale indicates the % of skeletal musculature in the body.
On an average, the 40% of the body weight is made up of the skeletal muscles.
In general, the percentage can increase in sportspeople in case of very prolonged physical activity. If a moderate
and daily physical activity is carried out, the % tends to increase but slowly. (The difference can be noticed
after months of
The percentage of musculature starts to decrease with the increase of age (after 40).
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
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.

To conclude, the fat body mass is subject to variations which can be recorded in weeks.

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
caloriesrequiredbythebodyaccordingtothephysicalstateandtothelife-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.
Bodymassindex
The body mass index (BMI) relates the body weight of a person with his/her height. The classification given
here below is correlated to the risk resulting from the influence of body weight on the state of health: when the
BMI ranges between 18.5 and 24.9, it means that the weight is not affecting statistically the state of health and,
therefore, it shall be deemed to be normal. Any deviation, exceeding both the whole value above or below such
range of BMI values, should be considered dangerous for your state of health. In such cases, it is recommended
to refer to your doctor. Getting used to follow a balanced diet is surely of help in increasing the quality of life,
promoting health and preventing diseases, as well as in increasing vitality and remaining in good shape!

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 is 77.3% (100%-22.7%).
The percentage of water is 56.4% (77.3% x 73%).
Body fat consists of:
• essential fat => 60.8 kg x 12%= 7.30 kg
• reserve fat => 60.8 kg x 15%= 9.12 kg
T
(60.8 kg) is equal to 27% (ideal % of fat mass for person 1). The difference between 22.7% (actual % of fat
mass) and 27% (ideal % of fat mass) is -4.3%, which applied to the total weight (60.8 kg) is equal to 2.6 kg.
