What should be the ratio of height and weight? The correct ratio of height and weight in men
What is the normal weight for a woman? Normal for what? For beauty or health? How does this parameter depend on age? In the article we will deal with these issues.
When it comes to health, it is most convenient to focus on body mass index. It is he who gives the most accurate idea of what weight is normal for you.
Yes, this tool is not perfect. Yes, it is criticized, but nothing simpler, better, and more accurate, no one has yet come up with.
The table below will give you a rough estimate of your body mass index. It is convenient to make more accurate calculations on this page.
The BMI of people of normal weight falls into the green zone. It is necessary to adhere to this zone regardless of age (over 20 years). Deviations in one direction or another indicate an increased risk to health. Note! A BMI below 19 is not a confirmation of compliance with the standard of beauty. Why - we will analyze at the end of the article.
Body mass index does not work for everyone. It is not suitable for people whose growth has not yet ended, pregnant women and athletes. They need other tests and special tables.
2. The norm of weight, taking into account age
If we talk about the dynamics of weight changes throughout life, then a statistical graph in percentiles will come in handy.
The graph takes into account age, but does not take into account height. It shows in what range the weight of healthy women usually lies and how it changes over the years.
As a rule, weight gain is associated with an increase in the fat component, less often in the muscle component. Decrease - with a decrease in bone and muscle mass. These age-related changes inevitably lead to a decrease in the level of health (and beauty). They can be prevented by balanced training, in which there is a place for weight training.
3. Weight and physique
There are two more important parameters used in assessing the weight of adults. This is the ratio of the waist and hips, and the percentage of fat in the body.
The first parameter indicates health risks more, the latter will help determine body composition.
The waist to hip ratio is easy to calculate. Divide your waist in centimeters by your hips.
The waist line runs strictly in the middle between the iliac crests (we put our hands on them when we rest the latter on our sides) and the lower palpable rib.
The norm for women is in the range of less than 0.80. Preobesity - 0.80-0.84. Obesity - more than 0.85.
For example, a girl has a waist of 72 cm, and hips - 97.
72 / 97 = 0.74 Great result!
In order to find out the content of adipose tissue in the body, you must at least visit a fitness club. A specialist, using a special device, a caliper, will measure the thickness of the skin fold and give you the result. But, something can be learned from a visual assessment.
The chart does not show the percentage of body fat in women of athletic build, only in photographs. In any case, maintaining 18-20% body fat or less for a long time and maintaining health can be quite a challenge.
It is even more important to use the ratio of muscle and fat mass in the body to assess beauty and health.
When there is little muscle mass, the figure may not look very attractive. It is for this reason that many girls with a low BMI value are unhappy with their bodies. Tara Reid illustrates this problem quite clearly. 
Her BMI is 16.7, on the border of the yellow and red zones.
Plus, a lot depends on the individual characteristics of the skin. However, a sufficient amount of muscle mass and a normal percentage of body fat will bring you closer to the beauty standard much more effectively than a minimum BMI.

Children's height and weight are rapidly changing quantities and are a very important indicator of a child's overall development. Sometimes it seems to parents that their child is growing by leaps and bounds: the recently bought jacket has already become cramped, the new shoes are already too small, and the little one has stretched out and become very large. But sooner or later, any parents ask themselves questions - what height and weight should a child have at his age? What parameters are considered normal?
To answer such questions, the World Health Organization (WHO) has developed tables of normal height and weight for children from birth to 17 years of age. These standards are suitable for assessing the development of a child of any nationality and do not depend on social status and place of residence.
It is worth noting that, according to WHO, children who are breastfed gain weight more slowly than their peers who are bottle-fed. However, the table takes into account averages, therefore it is applicable to all types of feeding.
The growth rate of a child depends on his age. As you know, the child begins to grow even in the womb and at birth, his height is 46-55 cm. In the first year of life, the child grows very quickly - on average, by about 25 cm. grows by 5-7 cm per year. In adolescence, in some years, a sharp jump in the growth of the child is possible (by 10-15 cm per year), which is normal and is associated with puberty.
Weight norms are usually proportional to height. The child actively gains weight in the first year of life, then the weight gain slows down significantly and becomes stable until the age of 17-18, depending on individual developmental characteristics.
Norms of growth and weight of children up to 1 year
According to WHO developments, the normal range for both boys and girls is allocated in the table of height and weight. Indicators "low" and "high" are a signal for parents to consult a doctor. If the real height or weight deviates significantly from the norm, this may be the result of a systemic disease or an unhealthy lifestyle - you should immediately consult a doctor and examine the child.

Height to weight ratio
There are different formulas for determining the optimal weight to height ratio. 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 by appearance, skin fold thickness, etc. With the same height and weight, one person may look full, another - completely normal.
The best indicator of 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 ideal weight, the most popular method is the height-weight index, body mass index - Quetelet index.
Formula: body weight in kg divided by height in meters squared B / (P * P)
For example: height 170 cm, weight 65 kg. So 65: (1.7 * 1.7) = 22.5
The norm for men is 19-25. For women - 19-24.

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 weight men and women should gradually increase with age - this is a normal physiological process. Kilograms, which some people consider "superfluous", in fact, they may not be. Can be used to determine the optimal weight formula according to 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: identifying height-age-weight relationships
One of the most popular methods for calculating ideal weight is Brock's formula. She takes into account height to weight ratio, body type and age of the 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).

In people with an asthenic (thin-boned) body type, the longitudinal dimensions prevail over the transverse ones: the limbs are long, the bone is thin, 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 (that is, 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.
1. 6.5 wrist circumference equals chest circumference.
2. 85% of the chest circumference is equal to the circumference of the hips.
3. To get the waist circumference, you need to take 70% of the chest circumference.
4. 53% of the circumference of the bust is equal to the circumference of the thigh.
5. For the girth of the neck, you need to take 37% of the girth of the chest.
6. The circumference of the biceps is about 36% of the circumference of the chest.
7. The girth for the lower leg is slightly less than 34%.
8. The girth of the forearm should be equal to 29% of the girth 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 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.
It is important for everyone to monitor their health, especially for men who do not always adhere to this rule. For this, specialists compiled a special table, according to which you can independently track the ratio of height and body weight. It contains information on how to independently determine the type of physique, standard data based on age. Together with the table, extremely simple formulas are used, the norm is calculated individually for each man.
To get the correct data, before the calculations, you need to clarify the type of physique:
- A normal physique for men implies the presence of an index of 18-20 cm, the proportions of the body are correct, the main dimensions are clearly observed.
- The so-called "broad bone", when a lot of weight is possible with small stature and massive bones. It is assumed to use an index of 20 cm or more. Body proportions are completely different. These are massive people who have heavy shoulders, overall body parts in the absence of fat. The hips are usually wide, the legs are short, the chest is massive.
- Thin-boned people are more graceful, for men this type is not uncommon, although it is mistakenly considered otherwise. The index is set to 18 cm. This asthenic type suggests the presence of long and thin limbs, a neck. The muscles are not so strongly developed, the longitudinal dimensions of the body prevail over the transverse ones.. Often such people are considered painful, although in reality this is absolutely not the case. The main thing is that all proportions are observed, there are no deviations in the calculations.
Effect of age on weight
In order for the calculations to be as accurate as possible, it is necessary to additionally take into account such an important factor as the age of the man. On average, a young and strong person is taller than an elderly person. Even normal weight at different ages can vary.
A special formula is used that allows you to clarify the ratio - weight and height. For example, the following ratio is observed: body weight \u003d 50 + 0.75 (height - 150) + (age - 20) / 4.
Using such a simple formula, it is very easy to calculate normal weight, knowing height and age. For example, for a man with a height of 183 cm and an age of 40 years, the normal weight will be:
50 + 0.75 (183-150) + (40-20) / 4 \u003d 50 + 0.75 * 35 + 20/4 \u003d 50 + 26.25 + 5 \u003d 81.25 kg.
With a height of 183 cm, the norm is 81.25 kg. But this is only an ideal indicator, in order to clarify it, it is necessary to use a special physique table.
Formulas for calculation
To calculate the norm of height and weight in men, you can use different formulas that require certain data. The most popular for home use are 2 formulas.
Nagler formula. This formula helps to calculate how much body weight corresponds to overall height. This resulting number is considered ideal, it is enough to determine the height and mass. For example, 152.4 cm should account for 45 kg. If the height is higher, then for every 2.45 cm, 900 g must be added. Additionally, it adds 10% of body weight. If the ratio with other data is equal to the example given, then height-weight is normal. If there are big discrepancies, then it is necessary to start taking measures. For example, optimize the menu or consult a doctor if there are symptoms of any diseases.
Formula by John McCallum. This formula for determining the ratio of height and weight in men is considered the best today. It is based on data acquisition when measuring the wrist. The percentages are as follows:
- chest girth should be equal to 6.5 girth for the wrist;
- the circumference of the hips should be equal to 85% in relation to the chest;
- 70% of the circumference of the chest are equal to the norm of the circumference of the waist;
- 37% of the chest circumference is equal to the neck circumference;
- 36% of the value of the girth of the chest is equal to the value of the girth of the biceps;
- and for the lower leg, this value is approximately 34% of the girth;
- 29% of the chest girth value is equal to the forearm girth value.
It should be noted that the rate of height and weight is highly dependent on the general physique of a man. Therefore, when using formulas, it is necessary to use a special table showing the dependence of a normal, thin or massive physique on all the data obtained. Doctors usually use this method to obtain the most accurate and reliable data.
Table for men
To determine your own ratio of height and weight, you can use the special data that was obtained by specialists.
Asthenic build, i.e. lean:
- at 155 cm - 49 kg;
- at 160 cm - 53.5 kg;
- at 165 cm - 57 kg;
- at 170 cm - 60.5 kg;
- at 175 cm - 65 kg;
- at 180 cm - 69 kg;
- at 185 cm - 73.5 kg.
Normosthenic addition, i.e., the norm of weight and height:
- with a height of 155 cm, the weight is 56 kg;
- at 160 cm - 60 kg;
- at 165 cm - 63.5 kg;
- at 170 cm - 68 kg;
- at 175 cm - 72 kg;
- at 180 cm - 75 kg;
- at 185 cm - 79 kg.
Hypersthenic addition, i.e. the so-called wide bone:
- at 155 cm - 62 kg;
- at 160 cm - 66 kg;
- at 165 cm - 69.5 kg;
- at 170 cm - 74 kg;
- at 175 cm - 78 kg;
- at 180 cm - 81 kg;
- at 185 cm - 85 kg.
Using such simple ratios, you can easily determine at home how much your own weight corresponds not only to height, but also to the general body type. If there are strong discrepancies, but it is necessary to consult a doctor. A man must strictly follow all recommendations for bringing the ratio back to normal, as this greatly affects the general state of health and even whether he is able to have children.
Obesity or severe underweight is always not only the cause, but also a sign of many diseases.
If the ratios are disturbed, treatment is often required, and not just a special diet. We must not forget that for the male part of the population, food should be more high-calorie, since energy consumption is greater.
The ratio of the body for a man is extremely important. To determine at home whether there are discrepancies, you can use numerous and extremely simple formulas and tabular data. If serious discrepancies are observed, it is recommended to contact the observing doctor, who will prescribe an examination. In most cases, you can get by with a special diet, but there is another percentage when excessive thinness or high weight are signs of serious illness.
Regular examination will help to avoid such situations, experts recommend going through it about once a year to prevent the development of many problems in the future.
There is such a value that differs for women and men as the weight and height index (BMI), which helps to assess the correspondence of a person’s mass with his height.
It helps to identify excess, normal or missing weight, which is very important if you need to treat the body or to self-correct your figure.
What is "body mass index"
Back in the 19th century, doctors determined that the appearance of diseases is directly related to the presence of fatty matter in humans. To determine the optimal weight, it was necessary to calculate the ratio of human height to its weight.
In 1869, the doctor A. Quetelet invented a method for calculating the index, which allows you to assess how much body weight fits the existing height. Over time, many scientists have made various corrections and new formulas have appeared. But the rules have varied over time.
Recently, the optimal BMI has decreased, and this has led to an increase in the number of people who are overweight and obese.
Optimal body weight - the established range within which weight can move without affecting the functioning of the body
How is BMI determined?
Sometimes, the calculation of BMI does not provide accurate data. This is due to the fact that people have a different ratio between muscle and fat mass, which is due to many factors. Therefore, individuals with the same indicator do not look the same.
For a correct calculation of BMI, age, gender and type (thin-boned, medium-boned and wide-boned) build, established based on measurements of the girth of the wrist, are taken into account.
An objective value is considered to be the proportion expressed as a percentage between fat and musculoskeletal tissue for women - 13-20%, for men - 10-15%.
Thin people with narrow bone formation have a lower standard compared to owners of large forms. Sometimes, to determine the constitution of the body, the volume of the chest is measured.
Due to the peculiarities in the structure of the female and male figure, their BMI is different. It is also necessary to take into account the age of the person being checked, because the optimal weight will differ for a young and an elderly person.
When analyzing the body mass index (the ratio of weight and height), one should take into account the fact that for men and women it will be different due to the peculiarities in the structure of the female and male figures. Over the years, a fat layer is added that is heavier than muscle tissue. Because of this, a mature person can have an ideal ratio and be overweight at the same time.
Special calculations are used to determine the optimal mass index of children. In a special way, BMI is calculated for athletes. Thanks to training, they have powerful muscles, and their ideal weight will be much higher than that of an ordinary person.
How to calculate BMI using formulas
When calculating the index of weight and height, they mainly use such simple actions: for women, 110 is subtracted from height (cm), and 100 for men. But in this formula, age, constitution of the individual, and other factors are overlooked.
It is quite difficult to calculate the correct indicator on your own, taking into account all the subtleties. For people who want to maintain their weight in order, a calculator was invented - online. 
You just need to write down your data (height, weight) in a certain form and after 2-3 s. the display will show the result. Additionally, mention of the circumference of the hips and wrists may be required.
The results obtained must be compared with the table, and a conclusion should be made about the body weight of the subject.
Calculation of body mass index by different methods
There are various ways to calculate the index, by which it is possible to independently determine your suitable weight and determine how many kilograms you need to lose. It is very important to remember that none of the methods will give an accurate idea of the existing body composition, because. every organism has its own characteristics.
Only a highly qualified specialist will help to correctly assess the condition of the patient's physical body. If the available weight is slightly different from the calculated norm, while feeling great, do not panic. Most likely, this is the individual norm.
Brocca's formula
The most recognized and common is the formula of the French anthropologist Brock, suitable for people of normal build who are above 150 cm and below 185 cm.
Having a certain growth, you need to subtract the coefficient:
- up to 165 cm - 100;
- up to 175 cm - 105;
- from 175 and above -110.
In this calculation, it is necessary to take into account the type of physique, and change the result:
- Asthenic (thin bone) - reduce by 10%;
- With normosthenic (medium bone) - subtract 110 from growth;
- Hypersthenic (wide-boned) - increase by 10%.
The optimal weight for women and men is calculated differently depending on the type of addition To determine your type, you need to measure the circumference of the wrist of the working hand. Women's sizes for all types in order - up to 16, 16-18, 18 and above. Men have such girth values - up to 17, 17-20, more than 20.
Quetelet formula
A mathematician of Belgian origin Quetelet proposed his own method for calculating BMI. The formula is elementary, and consists in the need to divide the weight of the subject by the height (meters) squared.
| Classification based on BMI | BMI | What to do |
| underweight | 19 | recommended to increase weight |
| -great shortage | Under 16 | |
| - medium deficit | 16-17 | |
| -small shortfall | 17-19 | |
| normal weight | 19,5-25,0 | |
| Excess body weight | Over 25 | need to reduce weight |
| 1 stage obesity | 25-30 | |
| stage 2 obesity | 30-35 | strongly recommend weight reduction |
| 3 stage obesity | 35-40 | |
| stage 4 obesity | over 40 | need to lose weight immediately |
These indicators are applicable to representatives of both the stronger and the weaker sex.
This calculation has some corrections. For example, it is not suitable for pregnant women, the elderly and children. The coefficient may vary depending on the complexion or the amount of muscle mass.
If the indicator is above 30 units. it is advisable to take serious measures: visit a qualified specialist, contact a nutritionist and go in for sports. 
Lorentz formula
The weight and height index for women can be calculated using a very simple Lorenz formula, which will help to get a value very similar to the results of other, more painstaking calculations.
To derive the coefficient, you need to know your height in centimeters (P) and carry out the following calculations:
- R-100-(R-150)/2. The resulting number indicates a normal mass, favorable for a person;
- For the abbreviated Lorentz formula, P / 2 -25 is necessary. In other words, subtract 25 from half of our growth.
This technique is relative, and does not allow you to find out the optimal weight with absolute accuracy. Body type is not taken into account here and the age factor is overlooked. Indeed, at different ages, different body weights are considered the norm.
Breitman formula
To derive the weight and height index according to the Breitman formula for women, with a height of 165, it is necessary to subtract 100 from 165. For a universal calculation, you need to multiply the growth by a factor of 0.7 and subtract 50.
Body mass index for women
The mass index of weight and height is easy to calculate for women by applying Brock's formula: we subtract 100 from height in cm. If we subtract 10% from the result, we will get the ideal weight.
Having received too high a value, it can be argued that the subject is at risk, and is prone to diseases of the cardiovascular system, hypertension, impaired respiratory system functions, etc.
The extracted norm can be considered for each lady individually. It is due to age, and is different in young girls and mature women. For a more accurate definition, it is also worth considering the proportion of muscle and adipose tissue.
So, if you use the Quetelet form to calculate the BMI of a girl using average parameters, then with a height of 1.71 and a weight of 64 kg, we get: 1.71 * 1.71 = 2.9241; 64/2.9241=21.89. Normal for the fairer sex is an indicator from 19 to 24, and in this example it is normal.
Body mass index for men
The weight of a man depends on the individual physical form, well-being, and is commensurate with the height and width of the chest. The presence of excess kilograms indicates deviations in the work of many body systems, therefore it is very important to determine your ideal weight and stick to it.
You can calculate BMI for a man with average parameters (height-176, weight-88) using the formula: 88 / (1.76 * 1.76) \u003d 28.4. A value from 19 to 25 is considered a normal coefficient. The coefficient found above indicates extra pounds.
A clearer idea of the distribution of adipose tissue can be defined as follows: divide the waist by the volume of the buttocks. For the stronger sex, the norm is 0.85.
By applying the Nagler formula, a man can independently find his optimal ratio.
Having a height of 152 cm, the body weight should be 45 kg. Adding 0.9 kg to the weight for every next 2.45 cm of height, we derive a number, and if it matches the actual kilograms, then this is regarded as the norm. If there is a large discrepancy, it is advisable to take the necessary measures.
With the help of growth (P) BMI for the stronger sex can also be calculated as follows: P-(100+(P-100)/20)
Body mass index for children
Similar to calculating BMI for adults, you can calculate this indicator for children and identify excess kilograms, or a tendency to obesity. 
BMI = weight in kg / square of height in m.
For example, if we take the average value, when a child with a height of 1.5 m. weighs 45 kg, then we get: 45 / 2.25 \u003d 20. For a girl or boy 13-14 years old, this is considered normal. Children are constantly growing, and this means that this factor must be paid attention to. The table below shows the optimal indices for different ages.
| Child's age | Girl | Boy |
| 0-2 | 13,3-15,4 | 13,4-15,7 |
| 2-3 | 15,3-16 | 15,3-16,5 |
| 4-5 | 13,5-16,5 | 13,8-16,8 |
| 5 | 13-17 | 13-17 |
| 6-8 | 13,5-18 | 13,5-18,5 |
| 9-10 | 14-20 | 14-21 |
| 11 | 14,5-20,5 | 14,5-21,2 |
| 12 | 16-21,5 | 15-22 |
| 13-14 | 16-23 | 16-23 |
| 15-16 | 17-23,5 | 17,5-24 |
Even with the available data, the indicators are not easy to interpret. If in any doubt, it is best to consult a pediatrician. He will help determine the optimal weight and overall development of the child's body, and in case of deviations he will be able to give the necessary recommendations.
Body mass index for teenagers
To correctly determine the BMI of a teenager, it is necessary to make the same calculations as for children, because using adult measurements is not entirely correct. During puberty, it is necessary to carefully monitor the body weight of a teenager. The coefficient is calculated using the percentile. 
To find it, weight must be divided by height squared..
The resulting value does not contain the proportion of commensurate tissue types with growth, because of this there is the possibility of inaccuracies and misinterpretations.
The obtained result must be compared with certain data, due to the age of the teenager, and we will get a comparative value (SV BMI).
In boys and girls, this figure may differ, because the average level of muscle mass in men is higher than in women.
The found result of CV BMI meets the following indicators:
- more than 95 - obesity;
- from 85 to 95 - overweight;
- from 5 to 85 - the norm;
- less than 5 - lack of body weight.
Body mass index during pregnancy
The weight and height index for women during childbearing is calculated using the Quetelet formula. This coefficient is determined by the gestational age, and by comparing it with the permissible norms, you can find out how many kilograms a future mother can gain. To do this, you still need to know the weight of the lady before conception and her height. 
Insufficient weight gain by a pregnant woman can be a reason for abnormalities in the development of the fetus. Excessive addition of kilograms can cause difficulties in independent childbirth.
The norm during pregnancy is the addition of 7 to 16 kg. But in practice, it happens that mothers with extra or missing kilograms have produced healthy babies.
If there are doubts that the weight of the expectant mother can cause negative consequences for the baby, do not worry prematurely.
The maximum allowable body weight, taking into account age
The weight and height index is easy to find for women under 40, subtracting 110 from height in centimeters, and for ladies after 40 years, subtract 100cm.
It is obvious that with age, weight increases due to changes in carbohydrate metabolism, and this process is natural. This reduces:
- metabolism;
- changes in energy and physical activity;
- volume of muscle structure;
- metabolic movement;
- hormone activity.
Optimal body weight varies for different ages Many scientists use the Egorov-Levitsky standards to calculate the allowable weight coefficient for ladies. These indicators indicate the maximum allowable weight at a particular age. Exceeding the BMI below indicates excess body weight.
| Height, m | Age, years | ||
| 20-30 | 31-40 | 41-50 | |
| 1,66 | 65,2 | 71,8 | 76,5 |
| 1,68 | 68,5 | 73,7 | 78,2 |
| 1,70 | 69,2 | 75,8 | 79,8 |
| 1,72 | 72,8 | 79,3 | 82,8 |
| 1,74 | 74,3 | 79,0 | 83,7 |
Why you need to know your BMI
Knowing your BMI is necessary for those who care about their health and their figure. Doctors use this factor to select the dose of drugs. At home, you can control your weight with it.
The calculation of the indicator will help to identify the presence of abnormalities in the body, and their severity. Based on the data obtained, dieticians can prescribe an appropriate diet and exercise regimen for obese patients.
BMI is a standard way to determine the level of obesity in men and women
Nevertheless, with any weight adjustment, it is not recommended to trust only the obtained indicator. If it does not correspond to the norm, then it is worth doing additional research.
Analysis of BMI results
It is worth emphasizing that the BMI standard changes periodically. For example, in the US at the end of the 20th century, the normal index was 27.8. Then the standards changed, and the figure dropped to 25. This was the reason for the increase in the number of overweight citizens.
According to Israeli scientists, the optimal ratio for men is 25-27. For women, the normal index of weight and height completely coincides with the standard.
BMI has an indicative value and is used primarily by doctors and nutritionists. Having calculated the number yourself, it must be compared with WHO standards in a separate table.
When identifying obesity or underweight, you should not rely with full certainty on the derived index. So, people who have highly developed muscles and do not have extra pounds may have an overestimated figure.
Degrees of obesity by BMI
Having determined your weight and height index using Brock's formula for women, and identifying extra pounds, they classify overweight from optimal using the table:
| Excess,% | stage of obesity | Actual BMI |
| 20-30 | 1 | 25-30 |
| 31-50 | 2 | 30,1-36 |
| 51-99 | 3 | 36,1-40 |
| Over 100 | 4 | More than 40 |
Obesity levels 1 and 2 are considered as a minor cosmetic defect. It can cause mild discomfort, and cause further weight gain. At the extreme stage of obesity, pathological abnormalities are formed that affect all vital systems of the body.
Obesity can be of the following types:
- stable level for a long period of time;
- progressive- characterized by a rapidly increasing or slow continuous set of kilograms;
- residual- weight can increase significantly after a long period of weight loss.
Disadvantages and limitations in using the BMI method
The interpretation of the BMI values proposed by WHO does not take into account the age and sex of the individual. Evidence from many countries suggests that women's optimal weight index is lower than men's. In addition, it is higher among middle-aged citizens compared to young and old people.
The word “norm” means “averages”, but the statistics say that the “standards” for BMI, according to WHO regulations, do not correspond to the typical normal distribution of BMI indicators among residents.
It may be that the weight and height index, which is optimal for women in one country, will be overestimated for women living in many other countries of the world. For example, in Russia, if you follow the recommendations of the WHO, then most of the population over 30 years of age have extra pounds.
How to normalize body mass index
Excess weight, as well as insufficient, lead to serious disturbances in the functioning of the body. With small deviations from the norm, do not worry.
If the discrepancies are significant, first of all, you should consult a specialist. He will select the optimal diet and prescribe a diet.
- increase the calorie content of portions by increasing the intake of food and more frequent intake using protein products;
- engage in physical exercises aimed at adding body weight, excluding workouts that deplete the body;
- create conditions for healthy and sufficient sleep.
Those who have a non-critical excess of kilograms should adhere to the following rules:
- reduce the amount of food consumed;
- exclude fatty foods from the diet, reduce the intake of eggs, coffee, alcohol;
- diversify your diet with a sufficient amount of vegetables, fruits, low-fat dairy products, cereals, lean meat and fish;
- follow the diet. At night, it is better to drink kefir or eat fruit.
- choose sports activities that promote fat burning;
- breathe fresh air as much as possible and get enough sleep.
It is advisable to track your weight and height index, which is especially important for women, because its deviations can cause hormonal failure. A lack of body weight leads to a decline in strength, a decrease in immunity. Extra pounds create problems with the cardiovascular system, contribute to loss of activity.
