BODY COMPOSITION
The body composition is made up of:
• lean mass: all components without fat (water, muscle, connective tissue, and other non-fatty organic
components), bone, muscles, bowels, water, organs, and blood;
• fatty mass: all fats that can be extracted from adipose tissue and other tissues/organs;
• bone mass.
Through the electrodes located on the platform, the scale sends a weak, low intensity electrical current that
passes through the body. The different masses respond differently to the current: lean mass provides less
resistance than the opposite.
This body resistance is called bioelectrical impedance. The relative percentage of the various body masses
varies based on gender, age, and physical stature.
Body fat %
The body fat percentage indicated in the table below represents the total fat that is calculated by adding
essential fat and storage fat.
Essential fat is necessary for various bodily functions. The percentage is 3% in men and 12% in women.
Storage fat gives energy, protects against physical trauma, and insulates the body to preserve heat.
These percentages vary with the age and gender of the individual as shown in the table below.
If the percentages indicated by the scale do not fall within the values indicated as "normal" in the
table, we recommend consulting with your family physician.
Muscle Mass %
There are three different types of muscle: smooth, striated skeletal, and striated cardiac.
Smooth muscle is made of smooth fibres. These are found in the walls of the digestive tract, respiratory tract
and genital tract and in the wall of the venous and arterial blood vessels.
Human striated skeletal muscle is in the skeletal and facial muscles.
Cardiac striated muscle is found in the heart. This scale calculates the % of skeletal muscle and smooth
muscle tissue in the body. On average, 40% of body mass is made up of skeletal muscle. Men usually have
more pronounced muscles than women and the percentage may increase in those who practice sports.
The percentage of muscle starts to decrease with age.
Water %
The % of water in the body differs based on gender: in healthy adult women it ranges from 45% to 60% while
in men it ranges from 50% to 65%.
The percentage of water is greater in childhood and decreases with age.
Body weight variations can occur in a short period of time (hours), a medium period of time (days) or over a
long period (weeks).
Small variations in weight over a few hours is normal and due to water retention since extracellular water
(which includes the interstitial fluid, plasma, lymph and transcellular fluid) is the only part capable of varying
so rapidly.
When weight losses occur in just a few days, it is very likely that it is part of the total water.
Basal metabolic rate
The Basal Metabolic Rate, or BMR, is the minimum calories required for the human body to survive, in order
to carry out basic functions such as circulation, breathing, digestion, and maintaining body temperature. BMR
is calculated on a person when at physical and mental rest, lying down on their back, having not eaten for
12 hours, after at least 8 hours' sleep and with a constant body temperature of 20°C. Adult BMR varies from
1200 to 1800 kcal.
BMR is influenced by several factors: age, gender, height, body composition, fever / stress, nutritional state
and ambient temperature.
Considerations
When assessing your body composition trend, it is necessary to keep the following in mind:
• A decrease in weight accompanied by no change in body fat or even an increase in body fat means that
your body only lost water (for example, after exercising, time in the sauna or a limited diet for rapid weight
loss).
• An increase in weight accompanied by a decrease or no change in body fat indicates the development of
muscle mass.
• When the weight and body fat decrease at the same time it means that your diet is working and volume is
being lost.

Body mass index
The body mass index (BMI) is the relation of body weight to height. The classification given be low is
correlated to the risk that body weight exerts on health. When BMI is between 18.5 and 24.9 it means
that the weight does not statistically impact health and is to be considered normal.
Any deviation, above or below this BMI interval should be considered a health risk. In this case, we
recommend consulting a physician. Getting in the habit of following a balanced diet definitely helps improve
quality of life, promote health and prevent illness, increase
vitality and maintain ideal weight! It is important to know that
BMI does not allow accounting for weight variations due to
muscle mass, bone mass, water content or fat accumulation.
Therefore, a simple BMI calculation alone should not be
misinterpreted, leading to "DIY" diets. The evaluation of the
BMI should be made by a doctor or other specialists such as
a nutritionist or dietitian.
