�”Pioneers-Americans” faced with the problem of excess weight
It has long been known how overweight has a devastating effect on
the human body and what the consequences are.
First, increased body weight leads to cardiovascular
diseases and their complications. Known to raise the ideal
body weight of 10% leads to an increase in systolic and
diastolic pressure at 5mm Hg. Art., to increased mortality from
stroke and heart attack.
The second group of complications – the development of diabetes, the third –
increase in the number of oncological diseases.
�”Disease disease” – this is exactly what professor V.M. Dilman called
The main part of publications in information sources
tells us about health problems associated with elevated
weight, but also a lot of trouble may occur
human, if his weight is insufficient, based on his
So, how to calculate the ideal weight for any person?
Science distinguishes three main types of figure, which are still
- asthenic (ectomorph) – refers to the type of fine bone, with
which longitudinal dimensions prevail over the transverse, long
arms and legs, thin neck. Have an increased metabolism
resulting in heavy weight gain, low fat content.
With age, body fat is mainly concentrated in the area
belly. Muscles are underdeveloped.
- normostenic (mesomorph) – refer to the normal bone type, with
which body has proportionality of main dimensions and their
correct ratio. Men have broad shoulders and narrow
hips Women, unlike asthenics, seem more dense,
due to the greater muscle mass.
- hypersthenic (endomorph) – refer to the type of broad-boned
which transverse dimensions prevail over longitudinal, thoracic
the cage and hips are wide, the legs are rather short. Possess slow
metabolism, as a result, it is easy to gain excess weight, the body
has a high fat content.
In order to determine which of them you are,
it is necessary to measure the circumference of the wrist with a tape
hands and compare the results with the data in
|Type of figure||For men||For women|
|normostenic (normal)||18-20 cm||15-17 cm|
|hypersthenic (wide bone)||more than 20 cm||more than 17 cm|
|asthenic (fine bone)||less than 18 cm||less than 15 cm|
There is another way to determine body type by
the intercostal angle, which is formed by our lowest
ribs. To do this, place your thumbs under the lower ribs and
Determine what angle you have turned out.
If the intercostal angle is acute, that is, less than 90 °, then your type
figures asthenic. If the angle is straight, exactly 90 ° –
normostenic If the angle is obtuse, your type of hypersthenic.
Next, proceed to the next step to calculate your
perfect weight …
Body Mass Index (BMI)
The body mass index makes it possible to determine the amount
allows to assess the compliance of a person’s height to his weight,
most find out whether his body weight is insufficient, perfect
or overweight for its growth.
To calculate BMI use the following
формулой, где I и есть величина ИМТ:
I = m / h²
m — вес в килограммах,
h — рост в метрах.
|Less than 16.0||3rd degree chronic energy failure|
|16.0-17.5||Grade 2 chronic energy deficiency|
|17.5-18.5||1st degree chronic energy deficiency|
|18.5-20.0 (20.0 – 22.0)||Perfect weight range, female (male) asthenic
|20.0-21.5 (22.0 – 24.0)||Perfect weight range, female (male) normostenic
|21.5-23.0 (24.0 – 26.0)||Perfect weight range, female (male) hypersthenic
|23.0-30.0 (26.0 – 30.0)||Overweight, female (male)|
|30.0-35.0||1st degree of obesity|
|35.0-40.0||2nd degree of obesity|
|More than 40.0||3rd degree of obesity|
Let us give an example of calculating the BMI and correct interpretation.

This we learn the minimum and maximum values of body weight,
using the extreme values for the range from the table.
Minimum weight (Mmin) = Imin * (h * h) = 20.0 * 2.89 = 57.80
kg То есть, 58 kg
Maximum weight (Mmax) = Imax * (h * h) = 21.5 * 2.89 = 62.13
kg То есть, 62 kg
It turns out that for a girl 170 cm tall.
like идеальный вес для здоровья считается в диапазоне 58-62 kg
Body fat percentage
It often happens that two girls of the same height and weight, and
имеющие одинаковый type of телосложения, могут иметь абсолютно разные
figures. One may have a taut sports figure, and the other
visible problem areas with excess weight.
Why is this happening? It’s all about the percentage of fat
tissue in the body of each of the girls.
Average The percentage of body fat also depends on age.
Because of the hormone estrogen, women have more body fat than
men. An average woman has a percentage of body fat.
about 23%, and for an average man – about 17%. With age
the amount of fat only increases and muscle mass
|Body fat level||men||women|
|Very low||< 10%||< 16%|
|Above the average||20-25%||26-30%|
|Tall||26-30% +||31-40% +|
For men ожирение начинается, если телесный жир достигает 25

At the same time, adipose tissue is vital for perfect
the functioning of the body. It is necessary for the insulation of the body,
protection of internal organs. Therefore, an excessive decrease in the percentage
body fat can cause many health problems.
Especially susceptible to this female body.
How to calculate the percentage of fat in your body? One of the most
The available methods are measurement of fat folds and diagnostic
Measurement of fat fold
characterizes the amount of subcutaneous fat, which is an indicator
total body fat percentage. For оценки отложения жира
use the measurement of the thickness of the folds in the abdomen, upper
parts of the back, thighs.
Measurements are made with a special object resembling
caliper – caliper, on a scale on it and find out the thickness
Three measurements of each section are made and the average
the value is inserted into a special formula for calculating
the proportion of body fat. Huge role in the right
getting the result is the correct procedure
measurements, it is therefore very important to select an experienced specialist.
In diagnostic scales (fat analyzers) measurement of fat in
the body is produced by passing an impulse through the body
human: two electrodes are mounted in the floor platform
electronic scales. Using the measurement result of electric
resistance, a series of constants of the human body and
individual characteristics of a person (age, height, gender)
calculate the percentage of adipose tissue and other parameters
For мышечной ткани и водной среды характерна хорошая
electrical conductivity and therefore slight electrical
resistance. Bones and fatty tissue, by contrast, have low
electrical conductivity, because the cells of adipose tissue and bone due to
very high resistance practically do not conduct electrical
Attention! It should be noted that the fat analyzers do not
can be used by people with an implanted pacemaker,
as the principle of the fat analyzer is built on transmission
low frequency electrical signals through the human body that
may result in failure of the pacemaker.
P.S. Thus, having studied this article, you can already calculate
the ideal weight of your body and determine whether it lies within
If yes – heartily congratulate you! If your weight is
