There are many parameters by which you can evaluate the appearance and figure of girls. One of them is the ratio of weight and height. And how to determine it, what influences it?

In general, the ratio of weight and height is an individual indicator, because such values ​​\u200b\u200bcan vary from person to person.

For example, someone has a wide bone, and there are much more muscles (and after all, muscles weigh more than adipose tissue), while others have an undeveloped muscular system, and the bone is thin.

So, when determining such a ratio, some features must be taken into account. The first step is to measure and evaluate growth.

How to determine normal growth?

To measure your height, you need to take off your shoes, stand against the wall, pressing your back against it, and mark the highest point or ask someone to do it.

Then take measurements with a centimeter tape and evaluate the numbers obtained.

• If your height is less than 150 centimeters, then it can be considered low.
• With a value equal to 151-156 centimeters, growth can be considered below average.
• Height from 157 to 167 centimeters is considered average.
• If your height is 168-175 centimeters, then it can be safely called high.
• Height equal to 176 centimeters or more is considered very high.

Concrete values ​​are influenced, first of all, by heredity. So if both parents have an impressive weight, then the child, too, is likely to be distinguished by such a feature.

Body Types

The ratio of weight and height in girls directly depends on the constitution, that is, on the physique. In total, there are several types of physique:

But how do you determine your type? After all, not everyone takes care of themselves and at the same time write off excess body weight precisely on the features of the physique. And what is actually fat can be passed off as broad bone. But it's simple. Wrist fat is almost non-existent, so measure it.

• If the girth of the wrist was 16 centimeters or less (that is, it was possible to grasp it without effort, and at the same time there was a “margin”), then you can be attributed to asthenics.
• If during measurements you received values ​​\u200b\u200bfrom 16 to 18.5 centimeters (you managed to grab your hand, but with some effort), then you are a normosthenic.
• If the girth was more than 18.5 centimeters (it is almost impossible to wrap around the wrist), then most likely you are a hypersthenic.

We take into account age

As we age, it becomes difficult to keep fit. It is connected with metabolic processes.

If in young people the metabolism is normal or even accelerated (after all, all organs and systems work smoothly and without interruptions), then in people of a more mature age, the metabolism is slowed down. And the older the person, the slower his metabolism.

This is normal, because all tissues and cells age, and the aging process is the norm and, unfortunately, inevitable.

So, in girls under 20, as a rule, the metabolism is accelerated. In girls aged 20-30 years, it slows down a bit. If you are 30-40 years old, then metabolic processes are significantly slowed down.

In women 40-50 years old, the slowdown is obvious, and in women over 50 years old, the metabolism can be called slow. In some sources, it is this division into groups by age that is taken as the basis.

How to determine the ratio of weight and height?

So, how do girls determine the ratio of height and weight? You already know your height, age, and body type.

These parameters will be needed and will help to find the ideal ratio of height and weight. There are several ways to determine. Let's take a look at some of them.

Paul Broca formula

Paul Brock was a famous French anthropologist and, back in the 19th century, he proposed his simple formula for determining the ratio.

He suggested measuring height in centimeters and subtracting 100 from the resulting number. The result will show weight in kilograms.

But such a formula is irrelevant today, because scientists have gained knowledge about the features of the physique and other important points that have a direct impact on the figure and physique. But Paul Brock did not take such criteria into account.

But experts have adapted such a formula for modern people from 18 to 50 years old and suggest subtracting about 5-10% from the result.

Table definition

Another easy way to determine the ideal ratio of weight and height is to use the table. There are different tables: in some, indicators are given without taking into account gender and age, in others, gender is taken into account, in others, the type of physique is taken as the basis, in the fourth, both gender and age are taken into account.

One of the most accurate is the Quetelet table. It takes into account important factors such as age and gender. You need to find your height in the first column and draw a line from this cell to the cell (on the top line) with your age. Connect the lines and you will see your optimal weight.

But some experts believe that normal and ideal weight are slightly different. So, having found the normal weight in the table, subtract 2-3 kilograms from this number, and you will get the ideal body weight.

In addition, for asthenics, the values ​​\u200b\u200bwill be reduced, for hypersthenics - increased. The difference will be 2-4 kilograms.

Quetelet formula

If you want to know your individual parameters, then you can find the Quetelet index using the formula he proposed:

M \u003d 0.75 * (P - 150) + 50 + (B - 20) / 4

Now decoding: M is body weight, P is height, and B is age. Substitute all these values ​​into the formula and you will know the ideal weight to aim for.

To understand whether changes need to be made or not, you can calculate the Quetelet index. Here is the formula for calculating:

IR \u003d B / (P * P)

IC here is the Quetelet index, P is height, and B is weight in kilograms. If the resulting figure is less than 18.5, then there is a deficiency in body weight. If the value is in the range of 18.6-24.9, then the weight can be considered normal. With a value from 25 to 29.9, we can talk about excess body weight. Indicators in the range of 30-34.9 can be considered a sign of obesity of the 1st degree, and then there is obesity of the second degree.

Determine your ideal weight and strive for perfection!

There are different formulas for determining the optimal ratio of weight and height. Here it should be borne in mind that with the same height and weight, one person may look full, the other - completely normal.

If you know the body mass index, you can judge obesity or underweight. The index is calculated for adult men and women from 20 to 65 years old. The results may be false for pregnant and lactating women, athletes, the elderly and adolescents (under 18).
How to count? Square your height in meters, then divide your body weight in kilograms by the resulting figure. For example: height 170 cm, weight 65 kg. So 65: (1.7 * 1.7) = 22.5.
The resulting number will be your index. The norm for men is 19-25. For women - 19-24.

Method 2. Volumes

The Quetelet index is a good indicator of the amount of fat in the body, but does not indicate how fat is distributed, in other words, it does not give a visual picture. But you can check your body for ideality using another formula.
The distribution of fat throughout the body is determined by the ratio: waist circumference (at the level of the navel) divided by the volume of the buttocks. The norm for men is 0.85; for women - 0.65 - 0.85.

Method 3. Taking into account age

It has been proven that the weight of a man and a woman should gradually increase with age - this is a normal physiological process. Kilograms, which some people consider "superfluous", in fact, they may not be. You can use the formula to determine the optimal weight depending on age.
P - in this case, height, and B - age in years. Body weight \u003d 50 + 0.75 (P - 150) + (B - 20): 4

Method 4. Brock's formula

One of the most popular methods for calculating ideal weight is Brock's formula. It takes into account the ratio of height, weight, body type and age of a person.
Brock's formula for people under 40 years old: height (in cm) minus 110, after 40 years - height (in cm) minus 100.
At the same time, people with an asthenic (thin-boned) body type should subtract 10% from the result, and people with a hypersthenic (broad-boned) body type should add 10% to the result.
How to determine your body type? It is enough to measure the circumference of the thinnest place on the wrist with a centimeter.

Method 5. Nagler formula

There is a Nagler formula that allows you to calculate the ideal ratio of weight and height. For 152.4 cm of height there should be 45 kg of weight. For every inch (that is, 2.54 cm) over 152.4 cm, there should be another 900 g. Plus another 10% of the resulting weight.

Method 6. Formula John McCallum

One of the best formulas was created by expert methodologist John McCallum. Its formula is based on measuring the girth of the wrist.
The circumference of the wrist multiplied by 6.5 is equal to the circumference of the chest.
85% of the chest circumference is equal to the circumference of the hips.
To get the waist circumference, you need to take 70% of the chest circumference.
53% of the chest circumference is equal to the thigh circumference.
For the neck circumference, you need to take 37% of the chest circumference.
The circumference of the biceps is about 36% of the circumference of the chest.
The girth for the lower leg is slightly less than 34%.
The circumference of the forearm should be equal to 29% of the circumference of the chest.
But not all physical data will exactly correspond to these ratios, the numbers have an average, average value.
A few more options for the ratio of height and weight:
The physique is considered ideal if the waist circumference is 25 cm less than the circumference of the hips, and the circumference of the hips is approximately equal to the circumference of the chest.
The waist circumference should be equal to: height in centimeters - 100. That is, a woman with a height of 172 cm will be proportionately folded if the waist circumference is 72 cm, the hips and waist are about 97 cm, that is, if she wears clothing size 48.
If the circumference of the hips is less than the circumference of the chest, and the circumference of the waist is less than the circumference of the hips by 20 cm, then such a figure is called an "apple". If the chest circumference is less than the hip circumference, and the waist circumference is 30 cm or more less than the hip circumference, this is a pear-shaped figure.
For women and girls of average height - from 165 to 175 cm - this observation turned out to be fair. Their waist circumference in centimeters is approximately equal to their weight in kilograms. One kilogram of weight loss gives a decrease in the waist by one centimeter.

Scientists have found that height and weight of children up to 5 years determined by the conditions of life, not genes. WHO experts also believe that the physical development of children under 5 years of age is largely determined by living conditions, and not by heredity. A study involving more than 8,000 children from Europe, Asia and America showed that, despite individual differences, the average weight and height of children from different countries differ slightly. According to a study, WHO has released new tables of the normal ratio of weight and height in children.

The tables that existed before were compiled more than 20 years ago based on data on formula-fed children in the United States. Breastfed babies gain weight more slowly than formula-fed peers. According to WHO experts, inflated standards contributed to unreasonable recommendations for formula feeding, overfeeding and obesity. The scientists' data showed that the pre-existing weight ratio were overestimated by about 15-20%. For example, according to previous recommendations, normal the weight a one-year-old child was 10.2-12.93 kg; according to the new recommendations, this figure should be from 9.53 kg to 11.79 kg.

AT "Growth standards for children under five years" included weight-for-age ratio, height-for-age ratio, and weight-for-height ratio.

You need to know about the ratio of height and weight

There are different formulas for determining the optimal ratio of weight and height. But they are all conditional, since they do not take into account many other factors. Therefore, excess fat should be assessed not only by these ratios, but also in appearance, the thickness of the skin fold, etc. With the same height and weight one person may look fat, another may be perfectly normal.

Men Growth The weight m pounds / inches average weight in kg obesity 1.55 5"1 56 67 1.58 5"2 58 69 1.60 5"3 59 71 1.63 5"4 60 72 1.65 5"5 62 75 1.68 5"6 64 77 1.70 5"7 66 79 1.73 5"8 68 81 1.75 5"9 69 83 1.78 5"10 72 86 1.80 5"11 74 88 1.83 6"0 76 91 1.85 6"1 78 93 1.88 6"2 80 96 1.91 6"3 82 98

Best Body Fat Ratio

The objective parameter of an ideal body is the percentage of fat and musculoskeletal tissue. For men, the norm is 9 - 15% of fat from the total body weight, and for women - from 12 to 20%.

Quetelet index

Knowing the Body Mass Index (BMI), one can judge obesity or underweight. The index is calculated for adult men and women from 20 to 65 years old. The results may be false for pregnant and lactating women, athletes, the elderly and adolescents (under 18). Among the many different methods for calculating the ideal weight, the most popular method is height - weight indicator, body mass index - Quetelet index. Formula:
weight ( the weight) body in kg divided by growth in meters squared
B/(R*R)

The norm for men is 19-25. For women - 19-24.

Where is the place for fat?

The Quetelet index, obviously, shows the amount of fat in the body quite well, but does not indicate how fat is distributed in the body, in other words, it does not give a visual-aesthetic picture.

Thus, you can check your body for ideality according to one more formula. The distribution of fat throughout the body is determined by the ratio:
waist (at the level of the navel) / volume of the buttocks.

The norm for men is 0.85

For women - 0.65 - 0.85.

Does age affect height-to-weight ratio?

The answer is unequivocal. Yes, of course it does. Proved that male and female weight should gradually increase with age - this is a normal physiological process. Kilograms, which some people consider "superfluous", in fact, they may not be. You can use the formula to determine the optimal weight depending on age. P - in this case, height, and B - age in years. Body weight \u003d 50 + 0.75 (P - 150) + (B - 20): 4

Brock's formula for identifying height-age-weight relationships

One of the most popular methods for calculating ideal weight is Brock's formula. It takes into account the ratio of height, weight, body type and age of a person. And Brock's formula for people under 40 is "height (in cm) minus 110", after 40 years - "height (in cm) minus 100".

At the same time, people with an asthenic (thin-boned) body type should subtract 10% from the result, and people with a hypersthenic (broad-boned) body type should add 10% to the result.

How to determine your body type?

The physique is usually divided into 3 types: normosthenic, hypersthenic and asthenic. In order to find out what your body type is, it is enough to measure the circumference of the thinnest place on the wrist with a centimeter. The resulting circumference in centimeters will be the necessary indicator (Soloviev's index).

Your body type

body type	Solovyov index - for men	Soloviev index - for women	Typical for this body type
normosthenic (normal)	18-20 cm	15-17 cm	the physique is distinguished by the proportionality of the main dimensions and their correct ratio
hypersthenic (broad-boned)	over 20 cm	over 17 cm	In people with a hypersthenic (wide-boned) body type, the transverse dimensions of the body are much larger than in normosthenics and especially asthenics. Their bones are thick and heavy, their shoulders, chest and hips are wide, their legs are short.
asthenic (thin-boned)	less than 18 cm	less than 15 cm	In people with an asthenic (thin-boned) body type, longitudinal dimensions predominate over transverse ones: the limbs are long, thin bone, the neck is long, thin, the muscles are poorly developed.

Nagler's formula for the ratio of height and weight

There is a Nagler formula that allows you to calculate the ideal ratio of weight and height. 152.4 cm of height should account for 45 kilograms of weight. For every inch (i.e. 2.45 cm) over 152.4 cm there should be another 900 grams. Plus another 10% of the resulting weight.

John McCallum's Girth Ratio Formula

One of the best formulas created by expert methodologist John McCallum. The McCallum formula is based on measuring the girth of the wrist.

• 6.5 wrist circumference equals chest circumference.
• 85% of the chest circumference is equal to the circumference of the hips.
• To get the waist circumference, you need to take 70% of the chest circumference.
• 53% of the chest circumference is equal to the thigh circumference.
• For the neck circumference, you need to take 37% of the chest circumference.
• The circumference of the biceps is about 36% of the circumference of the chest.
• The girth for the lower leg is slightly less than 34%.
• The circumference of the forearm should be equal to 29% of the circumference of the chest.

But not everyone's physical data will exactly match these ratios, since they suggest that the size of the wrist is rigidly related to the size of all human bones. And for some it's not.

A few more ratios of height and weight

The physique is considered ideal if the waist circumference is 25 cm less than the circumference of the hips, and the circumference of the hips is approximately equal to the circumference of the chest. Waist circumference should be equal to "height in centimeters - 100". That is, a woman with a height of 172 cm will be proportionately folded if the waist circumference is 72 cm, the hip and waist circumference is about 97 cm, that is, if she wears a clothing size of 48. If the hip circumference is less than the chest circumference, and the waist circumference is less than the hip circumference by 20 cm, then such a figure is called an “apple”. If the chest circumference is less than the hip circumference, and the waist circumference is 30 cm or more less than the hip circumference, this is a pear-shaped figure. For women and girls of average height - from 165 to 175 cm - this observation turned out to be fair. Their waist circumference in centimeters is approximately equal to their weight in kilograms. One kilogram of weight loss gives a decrease in the waist by one centimeter.

The problem of excess weight worries many in our time. To be slim means to be beautiful and healthy. Men and women calculate their ideal weight and do their best to match the cherished figure. But how do you know what you're aiming for?

Most often, a simple formula is used - men subtract 100 from height in centimeters, and women 110. The resulting number is considered the optimal weight. However, this calculation does not take into account the age, body type of a person and other additional features. Therefore, it is not suitable for everyone. A more accurate result can be found by calculating the body mass index (BMI).

What is BMI

BMI is a value that shows how correct the ratio of height and weight of a person is. According to a special formula, it is calculated whether the subject is obese or malnourished. Often this method is used by doctors in the treatment of diseases associated with overweight or underweight.

The idea to calculate BMI belongs to a Belgian scientist who lived in the 19th century, by the name of Quetelet. Subsequently, many nutritionists and anthropologists made all kinds of adjustments to the table. At the moment, there are formulas by which you can find out BMI not only by Quetelet, but also by Brock, Humvee, Kreff and Devin. They received such names by the names of the scientists who calculated the indicators.

The formula for calculating BMI according to Brock was developed at the end of the 19th century by a doctor from France. It is ideal for the average man in the street with a height of 155 cm to 2 m. Brock's method was supplemented by Professor Kreff. In the calculations according to his method, the type of physique is taken into account.

According to a certain formula, you can find out if a person suffers from so-called central obesity. To do this, the waist is divided by the hips. A number above 0.9 indicates that the test subject has problems. An overhanging tummy is a threat to health. They say that extra centimeters at the waist deprive several years of life.

It should be noted that the indicators of the norm at different times differed. In recent years, the ideal BMI has become much smaller than before, and therefore the number of people suffering from overweight and obesity has statistically increased.

What does BMI depend on?

Sometimes the calculation of BMI gives not quite correct results. The fact is that it is important to remember that the ratio of adipose and muscle tissue in people is different and depends on many factors. Therefore, people with the same BMI do not look the same.

In order to make an accurate calculation of BMI, not only height is taken into account, but also a person’s age, gender, and body type, which is determined by the results of measuring the wrist.

There are fine-boned, normal-boned and broad-boned types. The BMI of lean individuals with narrow shoulders and chest should be less than those of hypersthenics with large forms. Sometimes, to determine the type of physique, the width of the chest is measured.

Due to differences in the ratio of musculature and adipose tissue, normal BMI is different men and women. It must also be taken into account age subject. The ideal weight of a young girl or guy will be different from the body weight of a mature person. This is not surprising. With age, the fat layer, which weighs less than muscle tissue, increases. So an elderly person can get an ideal indicator as a result of calculations, and at the same time have problems with being overweight. Therefore, people over 50 are advised to monitor their waist-to-hip ratio to prevent central obesity.

A special formula and table are used to calculate the normal body mass index of children. In addition, do not forget that the ideal weight of girls and boys cannot be identical either. Different indicators will be in children under 2 years old and upon reaching this age.

In a special way, the ideal weight of athletes is calculated. They devote a lot of time to training, and therefore have developed muscles. Their ideal BMI will be significantly higher than that of the average person.

Why you need to know BMI

BMI is useful to know for those who monitor their figure and health. Doctors also use this indicator to determine the doses of medicines. In everyday life, it is used to control body weight.

It is much easier to follow the figure knowing what to strive for. And sometimes it happens that people invent problems for themselves. Young girls, for example, exhaust themselves with diets at absolutely normal weight, which leads to anorexia.

Calculating the body mass index will help determine if a person has problems and how serious they are. Nutritionists, on the basis of the obtained indicators, recommend a certain diet and exercise to an obese patient.

How to calculate BMI

It is quite difficult to calculate the body mass index on your own, taking into account all the nuances. We can help our users to cope with this task. For people who care about their weight, an online body mass index calculator has been developed. All that is required is to enter your data into the form and in a couple of seconds the result will appear on the screen. As a rule, it is enough to know your exact weight. For a more reliable result, you should specify the volume of the hips and wrists.

Choose which formula to use to calculate, and then compare the resulting number with the data in the table. Based on the result, it can be judged whether the weight of the test person is normal. BMI also indicates whether a person is underweight or morbidly overweight. Obesity has several degrees. This is also taken into account in the calculations.

We offer a handy online body mass index calculator. Despite its simplicity, it is quite accurate. You can calculate the body mass index based on age using different formulas or derive an average that will be as close to the correct one as possible.

BMI - an approximate indicator

Even using the most accurate formula, it is impossible to calculate the ideal weight. Each person is individual. Therefore, do not be upset if your indicators go beyond the norm.

The mistake of many, and especially for the representatives of the beautiful half of humanity, is the desire to be like models from glossy magazines. The slightest deviation from the norm can cause panic.

Of course, if the calculations indicate painful fullness, it is worth thinking about and trying to achieve better results. Obesity does not have a favorable effect on general well-being and on the state of human health. Excess weight leads to hypertension, cardiovascular disease, diabetes and joint disease. Therefore, you should take action and get rid of extra pounds.

On the other hand, it happens that the BMI is within the normal range, and the body looks flabby and by no means young. In this case, you should not be proud of the results of the check and do not care about the figure. You should pay attention to sports or at least increase physical activity in order to put your body in order. But such people do not need a diet at all ..

In any case, do not get hung up on dry numbers. The main thing is general well-being.

Even if the test results showed a poor result, you should listen to yourself. When a person is satisfied with his reflection in the mirror, and doctors do not see a threat to health in extra pounds, it is better to forget about formulas and calculations and enjoy life in the usual rhythm.

Many modern girls follow the figure, try to be fit and slim. To determine the normal ratio of height and weight parameters, it is necessary to know the norms and adhere to them, regulating body weight with nutrition and regular physical training.

Scientific minds have long invented a formula that determines excess or lack of weight. This is BMI. This abbreviation stands for Body Mass Index. According to this calculation, the main indicators of the human body are evaluated.

The ratio of height and weight in a girl is necessary not only to determine beauty. Knowing how this formula works, you can suspect problems with the body or, conversely, not think about possible risks.

What should be the ratio of height and weight

The formula is a road sign that shows whether life is moving in the right direction. Or maybe it's time for a change.

Table of the ratio of height and weight in girls

There is an opinion that the optimal weight for a person is the one that was in his youth. But we should not forget that every year of life the human body does not get younger. The amount of muscle mass decreases, the fat layer increases. And if you take the Quetelet formula (BMI) as the correct criterion for determining weight, then you can be very wrong.

The correct calculation of this index can be affected by both the type of physique and the amount of muscle and body fat in the body.

How to start determining the correct proportions of the body

The ratio of height and weight in girls in the modern world is very different even from those that were 20-30 years ago. Today, the beauty of the female physique is determined by: height, proportions of the upper body and lower extremities. But all numbers are relative.

To determine the parameters of your body, you need to take several measurements:

Also, in addition, measurements of the neck, shoulders, hips, calf muscles, and chest are made. Together, all these indicators determine the proportionality of the physique.

How to measure height correctly

With age, growth also undergoes changes. Firstly, in the morning a person’s height is always 1-2 cm higher than in the evening. This is due to the fact that the body relaxes and stretches during sleep. Secondly, the growth of a person at 50 years old will not be the same as it was 20 years ago. Therefore, there is a need to make new measurements at regular intervals.

To properly measure your height, you need to take an assistant and a hard meter. The measuring tape should be left for measuring waist volumes.

In this position, at the top of the head (crown), the assistant needs to put a mark on the wall. Moreover, measurements are carried out strictly parallel to the floor. Measuring the distance from the top point to the bottom - there is growth. Every woman or girl is different.

To say that someone is more beautiful is impossible. But there are categories of female growth:

• "inch" - height up to 155 cm;
• below average height - 155-165 cm;
• girls of average height - 165-170 cm;
• above average height - 170-175 cm;
• tall girls - 175-185 cm;
• too tall or tall - 185 and above.

Body Types

The main body classification includes three types - these are asthenic, normosthenic and hypersthenic (endomorphic appearance).

• Asthenic physique

The ratio of height and weight in girls with this type of figure is characterized by general leanness and graceful upper and lower limbs. Usually their height is 167-172 cm. Girls with this type of figure are very light, thin, elegant. They do not tend to gain excess weight.

• Normstenic girls

A distinctive feature of this type of physique is the proportionality of the figure. These women are usually of average height and have a very harmonious physique. With age, they can gain 2-3 kg of excess weight.

This is a strong, stocky female body type. Usually below average height. They have a broad chest and broad shoulders. Girls with such a physique are usually prone to gaining excess weight.

To determine your body type, you need to know height, leg length and wrist size:

1. Asthenics- legs are 7-8 cm longer than ½ height. The circumference of the wrist is less than 15 cm.
2. Normostenics- legs are 3-5 cm longer than ½ height. Wrist girth 15.5 -18 cm.
3. Endomorphs- the legs are a couple of cm longer than ½ height. The circumference of the wrist is more than 18 cm.

There are also divisions according to the figure:

• The A-shaped figure has wide hips compared to narrow shoulders.
• X - figurative type of figure. Shoulders and hips are approximately equal in width. The waist is 20 cm smaller.
• H - figurative figure. Shoulders, waist and hips are about the same size.
• T - figurative figure. The “boyish” type is broad-shouldered with narrow hips.
• Oh - a figurative physique. This type of women is distinguished by the most voluminous part of their figure - the waist.

Quetelet index

In the middle of the 19th century, the scientist statistician and sociologist Adolf Quetelet created a formula by which one can determine the excess weight in a person. The Quetelet Index (BMI) is a correspondence between human height and weight, which helps to determine the amount of excess or underweight.

To calculate your body mass index, you need to divide your weight by (height in meters*height in meters). It looks like this - weight kg: (height in m) 2.

Example: 74 kg: (1.76 * 1.76) \u003d 23.88 - the resulting figure is the Quetelet formula or body mass index.

Degrees of the Quetelet mass index

The mass index must be used with caution. When calculating it, the amount of fat in the body of a given person is not taken into account. Therefore, this weight analysis is indicative only.

1. Index up to 18.5 - lack of weight. There is no risk of obesity. Women may experience hormonal disorders, miscarriages, hypotension, low hemoglobin.
2. Index 18.6 - 25 - weight is normal. No risk of disease. There is no need to reduce or increase weight. Changes in weight can only be a personal preference.
3. Index 25.1 - 30 - extra kg. There is a risk of gradual onset of hypertension, varicose veins, diabetes.
4. Index 30.1 - 35 - 1 degree of obesity. This disease is not only a lot of fat on the human body or a cosmetic defect. Starting from this degree of obesity, the cardiovascular system and the vessels of the brain bear a double burden. Sugar is not properly absorbed by the body, leading to diabetes.
5. Index 31.1 - 40 - 2nd degree of obesity. The need for urgent action is doubling. Arthrosis, arthritis, hypertension, strokes, heart attacks are the consequences of this disease.
6. Over 40.1 - 3 degree of obesity. The huge possibility of dying from all of the above diseases increases significantly. There is an urgent need to take measures to reduce excess weight.

Volumes

The height-to-weight ratio or Quetelet index is not an ideal indicator of a beautiful body in girls or the absence of health problems.

To BMI, you need to add a measurement of waist measurement. This parameter will be in addition to the Quetelet formula.

1. The centimeter tape showed more than 80 cm - there is a small chance of developing metabolic diseases.
2. Measurements with a centimeter tape showed a waist circumference exceeding 87 cm - a critical figure. There is a need to reduce weight due to possible health complications.

Brock's formula

The French surgeon Paul Brock in the 19th century developed a calculation by which one can determine the optimal weight indicator for a person. This calculation formula includes the need to know your height in cm from which you need to subtract one hundred. The resulting figure will be an indicator of the ideal weight.

But for a correct calculation, there is a need to know the type of your physique. So, girls with the same body weight may look different due to different body types.

• Asthenics - (measured in cm. growth - one hundred) - 1/10 of the result.
• Normosthenics - measured in cm. Height - one hundred.
• Endomorphs - (measured in cm. height - one hundred) + 1/10 of the result.

Naegler's formula

When calculating, use a certain height and weight. To the ideal 152.4 cm (this growth figure is considered ideal) - (to the next 2.5 cm) you need to add 0.9 kg of weight. Add 10% of the result to the output figure.

For example: initial height is 165 cm. 165-152.4=12.6:2.5=5.04*0.9=4.536. The resulting figure must be added to the ideal 45 kg = 49.536. And add 10%. As a result, we get 54.48 kg.

The Neger formula is not suitable for all body types. From a girl with high growth, you can make an "analexic".

John McCallum Formula

The body weight formula was developed by John McCallum, a sports expert and writer. Among athletes, this formula is recognized as the best. It should be determined by the volume of the wrist.

Body parameters according to McCallum:

• chest volume is 6.5 * per carpal volume;
• waist volume - measured chest volume * 0.53;
• hip volume - measured chest volume * 0.85;
• thigh (leg) volume - measured chest volume * 0.53;
• neck volume - measured chest volume * 0.37;
• biceps volume - measured chest volume * 0.36;
• lower leg volume - measured chest volume * 0.34;
• forearm volume - measured chest volume * 0.29.

Lorentz formula

At the beginning of the 20th century, a Dutch physicist calculated the perfect weight for a person. It is based on growth.

This calculation is suitable for people over 20 years old. Growth has no limits.

Formula for the beautiful half:(subtract 100 from height measured in cm) - (measured height in cm is 150) divided by 2.

Example: 175cm=(175-100)-(175-150)/2=75-25/2=62.5kg

Breitman formula

To determine the ideal weight for a particular person using the Breitman formula, it is necessary to use the height parameter in cm. The calculation is made according to the formula:

Measured growth parameter in cm. * per 0.7 and subtract 50.

Example: 176 cm*0.7-50=73.2 kg.

The calculation of the perfect weight according to this formula is more suitable for women of a more mature age.

The role of age in the ratio of height and weight

Over time, the human body undergoes changes. Muscle volume decreases, body fat increases. Due to hormonal age-related changes in women, there is a redistribution, and even excessive accumulation of subcutaneous fat. Therefore, there is a need to compare your weight not with youthful indicators, but taking into account age.

The famous surgeon Brox did his BMI calculation, laying down the number of years and features of the figure.

1. The best result of female weight up to 39 years. Height measured in cm is a factor of 110.
2. Best female weight 40+. Height measured in cm is 100.
3. For an asthenic physique, it is necessary to subtract 10% of the ideal weight.
4. For female endomorphs, add 10% of their ideal weight.

Calculation of the ratio of height and weight, based on the type of female figure

Having a perfect physique is the dream of any woman or girl. All people are different and this should be recognized. Every woman is unique, no matter what body proportions she has.

Norm of weight and height: table for women

Growth	19-29 years old	30-39 years old	40-50 years old
165	58,5	61,75	66,3
167	60,3	63,65	68,34
169	62,1	65,65	70,38
171	63,9	67,45	72,42
173	65,7	69,35	74,46
175	67,5	71,25	76,5

The numbers in this table show the average allowable weight of a woman at different ages.

Using a dedicated calculator

On the Internet, different types of online calculators have found their place, which can be used to calculate the optimal body weight using various formulas. The way to use the online calculator is very simple. You need to know the parameters of your body and enter the data into the calculator windows.

To find out your values ​​​​using the Quetelet formula, you only need to know the height of your body and weight. The online assistant will do the calculation himself.

The ratio of height and weight in a teenage girl

The formula will help you find out the BMI of the child. Children's calculation of the Quetelet index \u003d child weight in kg / height in m 2. For example: child height 1.35, weight 35 kg = 35/1.82=19.23. This is the norm for children 12-13 years old.

To determine the BMI of a teenager, it is necessary to make the same calculation as for babies. The Quetelet index for adults is not yet suitable for them, due to the constant growth of the body.

It is necessary to calculate the indicator - percentile. Percentile = adolescent weight/height. The result obtained must be compared with the values ​​that correspond to the age of the young man.

Indicators:

• The result is 95 and more - the disease is obesity.
• Result 80 - 95 - overweight.
• The result from 6 - 80 is normal weight.
• Less than 6 - lack of weight.

Body mass index during pregnancy

BMI during pregnancy is estimated according to the generally accepted Quetelet calculations. But this formula has its own peculiarities. To apply this calculation, you need to know the number of weeks of pregnancy, weight and height before pregnancy.

Formula: pre-pregnancy weight/height squared:

• result of 19.8 or less - underweight;
• result up to 26 - normal weight;
• anything over 26 is overweight.

During pregnancy, there is a need to monitor weight. Any changes in the mother's weight can affect the development of the child.

Why you need to know your BMI

The Quetelet index or formula is a relative indicator. But to know it is necessary and not even for the beauty of the body. In these figures, part of the health is hidden. Indicators that exceed the norm should alert.

Behind them are such serious diseases as varicose veins, arthrosis, thrombophlebitis, strokes, heart attacks, diabetes. Few people want to have so many problems in their body. Therefore, it becomes necessary to monitor your BMI in order to prevent excess weight with its consequences.

Disadvantages and limitations in using the BMI method

The Quetelet formula has its drawbacks. These should include:

• age is not taken into account in the calculations;
• well-developed muscles can be interpreted as a threat of overweight or obesity;
• there is no difference between male and female.

This includes both disadvantages and limitations. If you need in-depth calculations, you should take several different formulas.

How to normalize body mass index

For girls who want to lose weight or gain weight, calculating the body mass index can be an assistant. You need to know certain rules. They are very similar for both groups.

The body mass index in girls, and in another way the ratio of their height and weight, can become an assistant in solving health problems. And also to be a guide in achieving the desired proportions of the figure.
