How to find out the normal weight for your height. How to calculate body mass index using formulas

BMI calculation results are not suitable for weight estimation professional athletes, pregnant women, as well as people suffering from edema and other disorders leading to an incorrect assessment of the initial data.

The weight ranges in this calculator are calculated taking into account height, according to the methods of the World Health Organization (WHO).

The method of assessing weight using BMI is intended for the primary identification of underweight or excess weight. Receiving a score different from the norm is a reason to contact a nutritionist and endocrinologist in order to conduct an individual weight assessment and develop recommendations for its correction, if necessary.

Range ideal weight(normal) shows at what weight the probability of occurrence and recurrence of diseases associated with overweight or underweight is minimal. In addition, as practice shows, a person with a normal weight looks not only healthy, but also the most attractive. If you are adjusting your weight, it is highly recommended not to go beyond the norm in order to avoid health problems.

About weight categories

Underweight usually an indication for increased nutrition; It is also recommended to consult a nutritionist or endocrinologist. This category includes people who are malnourished or have a medical condition that causes them to lose weight.
Lack of body weight is also typical for professional models, gymnasts, ballerinas or girls who are overly keen on losing weight without the supervision of a nutritionist. Unfortunately, this can sometimes lead to health problems. Therefore, weight correction in this range should be accompanied by regular medical monitoring.

Norm shows the weight at which a person has the maximum chance of remaining healthy and, as a result, beautiful for as long as possible. Normal weight is not a guarantee of good health, but it significantly reduces the risk of disorders and diseases caused by being overweight or underweight. In addition, those with normal weight tend to feel good even after intense physical activity.

Obesity speaks of excess body weight. A person in this category often has some signs associated with excess weight (shortness of breath, increased blood pressure, fatigue, fat folds, dissatisfaction with his figure) and has every chance of moving into the obesity category. In this case, a slight weight correction to normal or to values close to it is recommended. It would also be a good idea to consult a nutritionist.

Obesity- index chronic disease associated with excess body weight. Obesity invariably leads to problems with the cardiovascular system and significantly increases the risk of acquiring other diseases (diabetes, hypertension, etc.). Treatment of obesity is carried out exclusively under the supervision of a nutritionist or endocrinologist, and only after conducting the necessary tests and determining its type. It is not recommended to engage in uncontrolled diets and serious physical activity if you are obese, as this can provoke additional problems.

Answers on questions

What specific weight is ideal for me?

The calculator calculates the ideal weight range for you based on your height. From this range you are free to choose any specific weight, depending on your preferences, beliefs and requirements for your figure. For example, adherents model figure strive to keep their weight at the lower limit.

If your priority is health and longevity healthy life, then the ideal weight is calculated based on medical statistics. In this case, the optimal weight is calculated based on a BMI of 23.

Can the assessment received be trusted?

Yes. Adult weight estimates are based on the results of authoritative studies from the World Health Organization (WHO). Weight assessment from birth to 18 years is carried out using a separate special method, also developed by WHO.

Why is gender not taken into account?

BMI assessment of adults is carried out in the same way for both men and women - this is justified by the results of statistical studies. At the same time, for assessing weight, gender and age are of fundamental importance.

Some other weight calculator gives a different result. What to believe?

There are a huge number of calculators designed to estimate weight based on height and gender. But their formulas, as a rule, were developed in the last century by individuals or teams based on criteria that are unknown to you or do not suit you (for example, formulas for evaluating athletes).

The WHO recommendations used in this calculator are designed for general modern people, taking into account the conditions modern life, medical advances and based on recent observations of the population of all continents of the planet. Therefore, we trust only this technique.

I believe the result should be different.

The assessment is made solely on the basis of the height and weight data you provide (as well as age and gender for children). If you receive unexpected results, please double-check all entered data. Also, make sure that you are not one of the women whose weight cannot be assessed through body mass index.

My result is underweight, but I want to lose more weight

There is nothing unusual in this; many professional models, dancers, and ballerinas do just that. However, in this case, it is recommended to lose weight only under the supervision of a nutritionist and endocrinologist, so as not to harm your health if it means something to you.

Please note that most people's bodies are not able to fully function in a state of underweight. And only a few, due to the characteristics of genetics (or disease, ecology, lifestyle), can live comfortably with a deficit of body weight: without risk to health and without experiencing malaise, dizziness and constant hunger.

My result is normal, but I consider myself fat (or thin)

If you have concerns about your figure, we recommend taking up fitness after consulting with a good nutritionist.

Please note that some elements of the figure are practically impossible to correct only with the help of fitness, exercise, diet, or a combination of these. Your goals should be analyzed by an experienced doctor to assess their reality, consequences and prescribe only the right procedures.

My result is pre-obesity (or obesity), but I don’t agree with it

If you are an athlete (or an amateur weightlifter) with increased muscle mass, then weight assessment by BMI is simply not intended for you (this is mentioned in). In any case, for an accurate individual weight assessment, contact a nutritionist - only in this case will you receive an authoritative result with a doctor’s seal.

Why am I considered too thin or fat even though my weight is normal?

Pay attention to the personalities and weight of the people who bother you. As a rule, they judge solely by themselves: subjectively. Overweight people always consider thin people to be skinny, and thin people always consider overweight people to be fat, moreover, both of them can have a weight within the healthy norm. Take into account social factors: try to exclude, suppress or ignore those judgments addressed to you that are based on ignorance, envy or personal hostility. Only an objective assessment of BMI, which clearly indicates the norm, excess or deficiency of mass, is worthy of trust; and trust your concerns about your figure only to supportive people in your weight category, or better yet, to an experienced nutritionist.

How to calculate body mass index (BMI)?

It is necessary to divide the weight indicated in kilograms by the square of the height indicated in meters. For example, with growth 178 cm and weight 69 kg calculation will be like this:
BMI = 69 / (1.78 * 1.78) = 21.78

Who doesn't want to look good and feel slim? But it’s not always clear how to calculate the ideal weight, what number you should strive for, and whether it’s necessary at all.

There are girls who are sincerely convinced that they need to lose weight, but in fact for them the opposite is true - they need to gain weight. There are women who think that everything is fine and a few extra pounds have no effect. Although medical statistics say otherwise.

In order to more objectively assess your weight, there are formulas for calculating excess weight. They are also not ideal and have a number of shortcomings. But they allow you to reconsider your view on the issue of excess weight. The most famous formulas for calculating ideal weight can be found in this article.

Determining ideal body weight

The methods we talk about differ from each other. And to some extent they reflect the evolution of methods for calculating ideal body weight. From the authoritarian Lorenz method, which is suitable only for young girls. Before Brock's formula, which takes into account body type and calculation formulas based on age and height.
If you are curious, read the article with pencil and paper in hand. But don't be too strict about the numbers you get. No formula can describe the individuality, lifestyle, health status and feelings of a particular woman at a particular weight.

First way. Lorentz method

Advantage of the Lorentz method: calculates the weight norm for those girls who are always 18. But seriously, this is one of the most stringent methods that you should not rely on.

The disadvantage of this method It is believed that it only works for girls, but not for guys. It should also not be used if the woman is taller than 175 cm.

According to this method, ideal body weight for girls should be calculated as follows:

Measure your height in centimeters.
Subtract 100 units from it.
The second action will be subtracting 150 centimeters from the height value.
Determine the difference between the first and second results.
Divide the resulting units in two.

This is what the formula for estimating body weight in females looks like: (P – 100) – (P – 150) / 2.

For example: the girl is 170 cm tall, we calculate: (170 – 100) – (170 – 150)/2 = 70 – 20/2 = 60 kg.

Second way. Quetelet index

The advantage of the Quetelet index is its versatility - it is suitable for both women and men.

The disadvantage of the formula is the impossibility of applying it to adolescents and the elderly. Also, you should not count on the objectivity of the method in case of very low or very high male and female stature. The method is valid for representatives of the stronger sex 1.68-1.88 meters, and the weak - 1.54-1.74 meters. He also “lies” to pregnant women, nursing mothers, and athletes.

Important! Calculating the correct weight norm begins with calculating BMI (body mass index).

Doctors often use BMI to determine whether there is obesity or dystrophy.

How to determine how many kilograms overweight has a girl? Using Quetelet's formula, BMI is calculated:

Find out a person's body weight in kilograms using scales.
Height is measured in meters.
The first indicator is divided by the square of the second.
Make a calculation and find your BMI in the table.
They will find out the result.

The method is accompanied by a table in which BMI is calculated by age:

Body mass index		Human weight parameters
From 18 to 25 years old	From 26 to 46 years old	Human weight parameters
> 17,5	> 18,0	State of anorexia
Up to 19.5	Up to 20	Small deficit
Up to 23	Up to 26	Norm
Up to 27	Up to 28	Pre-obesity state
Up to 30	Up to 31	1st degree obesity
Up to 35	Up to 36	2nd degree obesity
Up to 40	Up to 41	3rd degree obesity
40 and more	41 and more	4 degree obesity

For example: The 24-year-old girl has a height of 1.59 m and weighs 61 kg. When calculating the weight norm for a woman, it turns out: 61 kg / (1.59)2 = 24.1 (BMI). It turns out that there is a slight excess weight. If the girl was 2 years older, then her parameters would correspond to her age.

Third way. Broca's formula

Advantage: technique on how to correctly determine excess weight person according to Broca, suitable for people whose height is in the range of 155-200 cm.

Flaw: age is not taken into account.

Important! To find out the constitution of the body, you need to find the thinnest place on the wrist and determine its circumference.

The measurement results are found in the table:

The number 110 is subtracted from height in centimeters if the person’s age is under 40 years.
The older a man or woman is, the more he (she) will weigh. After a person reaches the age of forty, his parameter is calculated as follows: the number 100 is subtracted from his height.
Also, corrections in calculations are made for asthenic and hypersthenic types. In the first case, 10% is subtracted from the result, and in the second, the same percentages are added.

Example: You can determine the normal weight for a thirty-year-old woman as follows: subtract 110 units from her height of 167 cm. It turns out that her weight should be 57 kg. If she has an asthenic body type, the final result is: 57 – 5.7 = 51.3 kilograms, and if she has a hypersthenic body type, then 57 + 5.7 = 62.7 kilograms.

Fourth way. Nagler's method

The advantage of the Nagler method is that if you have growth data, you can calculate perfect amount kilogram for a girl.

Flaw: this formula is valid only for females. It does not take into account age and body type.

For 152.4 cm of female height they take 45 kg.
Then for each new inch (5.54 cm) another 0.9 kg is allocated.
At the end of the calculation, an additional 10% of the found weight is added.

Example: a representative of the fair sex has a height of 170 cm. To calculate, we subtract 152.4 from 170 cm. This is equal to 17.6. We divide this value by the size of an inch - 2.54 cm. We get 6.93, and multiply by 0.9 kg. As a result, we have 6.24 additional kilograms. 45 kg + 6.24 = 51.24 kg. Add 10% of the resulting weight 51.24 + 5.124. The result is that she should weigh approximately 56.364 kilograms.

Fifth way. Women's formula based on age and height

Advantage: this method takes into account age-related changes representatives of the fair sex.

Disadvantage is that the method is only suitable for women. It doesn't reflect their body type in any way.

The weight norm for most women gradually increases as they age. This is due to a slowdown in metabolic processes in their body, and is a natural phenomenon.

This formula answers the question of how to determine the correct kilogram rate for a woman, taking into account her age:
50 + 0.75 (Height – 150) + (Age – 20) / 4

Example: The woman is 42 years old and her height is 168 cm. Finding the ideal body weight:
50 + 0.75 (168 – 150) + (42 – 20) / 4 = 69 kilograms.

But we must not forget that we are all individual, and the ideal number of kilograms may differ from the calculated one - the main thing is that the person is comfortable.

In addition, the numbers on the scales often do not describe the state of the body and well-being, the ratio of fat and muscle tissue. Namely, they give beautiful curves and fit.

Which method of calculating your ideal weight did you like best?

Content

Many representatives of the stronger and fairer sex worry about the condition of their own figure. To determine a parameter called body mass index, the calculation formula is a medically recognized and objective method. It allows you to find out the relationship between weight and height and assess how well these two indicators correspond to each other. The figure calculated by the formula for body mass index within the normal range means that a person’s health is not threatened by problems associated with excess weight, and that his figure looks harmonious.

Formula for calculating body mass index

To calculate such an indicator as body mass index, the formula makes up a simple empirical relationship. Like other relative indicators, this criterion requires reservations when used in practice. The value can be significantly influenced by bone thickness and body type. Depending on the absence or presence of muscle mass, the same indicator value can correspond to both a fit, athletic and a dense figure.

Often, BMI adequately reflects the overall picture and can serve as a guide in deciding questions about losing weight or gaining weight. To calculate this indicator, you need to divide your own weight in kilograms by the square of your height in meters. If you are characterized by flabby body, overweight, but the index value (BMI) is within the normal range, focus on playing sports. If you want to lose a few kilograms, then physical education should be combined with proper nutrition. BMI calculation is needed for the following purposes:

Being overweight or underweight can lead to health problems later on. For example, being underweight leads to the inability to get pregnant, lack of menstruation, and osteoporosis.
A normal BMI can range from 18.50 to 24.99: this figure increases with age.
If after the calculation you find yourself with extra pounds, there is no need to panic. There is no serious threat to your health, but you can improve your condition: choose a set of exercises, start eating right.
If the calculation using the formula shows that you are obese, consult your doctor.

Ideal body weight

The formula for calculating ideal body weight is designed to determine optimal weight, which is a combination of the minimum probability of death from a number of diseases, for example, coronary heart disease, diabetes, hypertension, with maximum life expectancy. The value of this indicator, according to the formula, depends on the gender, height, and physique of a person.

The ideal weight is considered to be that which is statistically reliably combined with maximum life expectancy. But the concepts of “normal body weight” and “ideal body weight” are not identical. The latter indicator is an abstract value that is typical only for a small proportion of the population of developed countries. It depends on factors, among which the determining ones are gender, height, type of human constitution, for example, normosthenic, asthenic, hypersthenic.

If we evaluate overweight In terms of ideal body weight, the majority of the population will be diagnosed with varying degrees of obesity. This is a consequence of the artificially created hype around the entire industry slim body, which creates demand for various weight loss products. However, when calculating excess weight based on normal weight, obesity will be detected in a quarter of the population, which has been confirmed by numerous studies and is true. Normal weight may differ from ideal by 5-10%.

For women

Representatives of the fair sex who strive for the ideal will be interested in such an indicator as ideal body weight. It is a prerequisite for healthy, active longevity, but still remains a theoretical value. This indicator can be calculated. The famous doctor Margarita Koroleva suggests calculating based on the normal weight indicator using Brocca's formula: to do this, subtract one hundred from the height in centimeters. If 10% is subtracted from the obtained value, the ideal body weight will be obtained.

For men

An ideal body weight guarantees a man a high level of performance, mental and emotional stability, a good level of physical development. The presence of excess weight is not always obvious, since there is hidden or latent fatness, which is present in people who seem slim at first glance. An objective indicator of the percentage of fat and musculoskeletal tissue is 9-15% fat for the male body, 12-20% for the female body. When calculating the ideal weight for men, use the following formula: BMI = height – (100 + (height -100): 20).

For children and teenagers

The ideal weight for adolescents and children is the ratio of body weight in comparison with height, which guarantees a high life expectancy. This figure may be different for boys and girls, since the average proportion of muscle mass is higher in males than in females. A child’s ideal weight is calculated using the formula: MI = (P x G): 240, where P is height in cm, G is circumference chest in cm, 240 – constant coefficient.

Calculation of BMI using different methods

There are several methods for calculating body mass index using the formula. This makes it possible to find out the degree of correspondence between weight and height, whether a person has enough weight, whether there is a deficiency or excess. The indicator was developed by the Belgian Adolphe Ketele in 1869. Now the ability to calculate it has gained wide popularity due to the fact that excess weight is one of the most exciting, pressing problems of our time. If previously obesity was considered an indicator of health, now it is a disease.

Brocca's formula

French anthropologist and surgeon Paul Brocque proposed his method in the 19th century. Standard formulas do not take into account the natural change in mass over the course of life. Brokk included in the calculation data on the age category, information on body length, and the constitutional type of build to which the subject belongs. Nature intends that weight changes with age. The value that indicated extra pounds at a young age becomes the optimal indicator over time.

For people under forty, the French researcher recommends using the following formula: ideal weight = height (cm) - 110. If you are over forty, the following calculation method is suitable: height (cm) - 100. In addition to age, the formula should take into account height researched: the taller a person is, the more he will weigh. This technique recommends using the “Brocke-Brugsch growth index”:

if you are shorter than 1.65 m, your ideal weight will be “height (cm) – 100”;
if a person’s height is 1.65-1.75 m, to calculate this indicator you will need to subtract the number 105 from height (cm);
if you are taller than 1.75 m, subtract 110 from your height (cm).

In addition to height and age, it is necessary to take into account the physique or constitutional type of a person. There are three of them - sthenic, normosthenic, hypersthenic. Normosthenics are considered to be people who are not too short and not very tall, with a normal ratio of limb length to height, average volumes of the head and chest. For such people, the indicator obtained using Brocca's formula is the ideal weight.

Asthenics are thin people with narrow bones, tall stature, and pale skin. Representatives of this constitutional type should subtract 10% from the result obtained by the formula. If your appearance is more reminiscent of hypersthenics: you are a broad-boned, stocky person with developed muscles, you should add 10% to the resulting figure.

Quetelet's formula

Adolphe Quetelet was a Belgian mathematician and statistician. He proposed the BMI formula in the 19th century. Using it, you can determine the degree of obesity or malnutrition, and assess the possible risk of developing diseases that are associated with excess weight. BMI according to Quetelet’s formula is calculated as follows: BMI = weight (kg) : (height (m))2. The obtained result is compared with the following data:

for ages 19-24, the normal index is 19-24;
at 25-34 years old the norm is 20-25;
for people aged 35-44 years – 21-26;
the norm for 45-54 year olds is 21-27;
at 55-64 years old the normal index value is 21-28;
for people 65 years of age or older, the norm ranges from 21 to 29.

Lorentz formula

The Lorenz method of calculating BMI is considered the simplest and most well-known: you only need to know your height. His formula looks like this: ideal weight = (height (cm) - 100) – (height (cm) - 150)/2. The simplicity of this determination method is not considered the only advantage. The concept of ideal weight is always relative. Every formula is derived by analyzing the results of statistical studies that compare different parameters of people. The data obtained can only serve as a rough guide.

The advantage of the Lorentz formula is that it gives an indicator that is close to the results of more complex calculation methods. However, this index does not take into account a person’s body type, of which experts distinguish three: the weight norm varies for each. The age parameter is not taken into account, and depending on age, different weights are considered normal.

Maximum permissible body weight depending on age

There is no doubt that weight depends on age. It is directly related to the occurrence of such a biological process as carbohydrate metabolism. With age, the metabolism of energy, substances, motor activity slows down, the volume of muscle tissue and metabolic rate decrease. All this, together with a decrease in hormone activity and energy consumption, contributes to weight gain. Its change with age is an inevitable, natural process. This dependence is clearly demonstrated by the table below, which shows the values for normosthenics.

Classification of obesity by BMI

Obesity is a disease characterized by the accumulation of excess weight due to excess deposition of adipose tissue in certain areas. Obese people are at increased risk for many diseases, among which the first place is occupied by diseases of the cardiovascular system. Depending on the value that will be obtained after calculating BMI, you can determine the degree of obesity, if any, using the following table:

Classification of health status depending on body mass index			Health Risk
		more than 25 years	Health Risk
Anorexia ataroxic and nervous	BMI does not reach 17.5, weight is less than 15% of normal			Treatment of anorexia and weight gain by healthy eating
Underweight	Under 18.5		Absent

Excess body weight			Elevated	Losing body weight through a healthy diet and exercise
Obesity of the first degree			Elevated	Need to reduce body weight
Obesity of the second degree
Obesity of the third degree			Very tall
Obesity of the fourth degree	40.0 or more	41.0 or more	Excessively high	Urgent weight loss required

BMI calculator

The calculator helps to quickly determine an indicator that is considered an indirect assessment of excess or underweight, and a predisposition to the development of obesity. BMI is calculated for both men and women. To determine the indicator, enter your weight (kg) and height (cm). Next, click on the “Calculate index” button and your body mass index value will appear in the “BMI” field. Compare the data obtained with the table above.

The question of how to achieve your ideal weight has always been and will be relevant.

In search of their norm, few people think that the ideal weight bar is a combination of many factors, not only the number on the scale, but also well-being: physical, psychological and state of health upon reaching a particular weight category.

There are many various options calculating your ideal norm, but this is just an average statistical indicator that may differ. In this regard, it is necessary to focus on the general indicators of tables with designated standards weight categories depending on the height, age and gender of a person and find among them the indicator that will be comfortable for the person.

How to determine your ideal weight? Let's start with the fact that the concept of excess weight is only excess fat in the human body.

It's fat, not muscle. Many people mistakenly believe that pumped up muscle mass is considered excess weight; this is not true.

People with the same weight, age, height and gender can look completely different, depending on the presence or absence of muscles.

That is why one person will look plump and another slim, thanks to properly designed sports forms, like an athlete. In this regard, you should critically, as if from the outside, look at your body.

This look will help you see yourself and understand that the reasons for dissatisfaction with your figure are not broad bones, genetic inheritance, namely excess weight, or rather fat.

Where to begin?

After the realization came that it was necessary to get rid of unnecessary subcutaneous fat, you need to understand the following: ideal weight can be achieved only if you eat right and exercise. It is worth remembering that the method of grueling fasting or many hours of daily training can be not only useless, but also harmful, which is why it is important to do everything correctly and in moderation.

At proper weight loss worth remembering:

During menstrual periods, women tend to experience fluctuations in body weight.
In this regard, plus or minus one kilogram per day while losing weight is the norm.
It may also fluctuate depending on the amount of water you drink.
It may also change due to muscle mass gain.
Oddly enough, gaining muscle mass and thereby achieving a slender body contour can be accompanied by a slight upward change in body weight.
This is due to the fact that muscle weighs almost twice as much as fat.
It is very important not to overdo it and if the goal is simply to tighten the body, choose wisely physical activity.

Why you need to know your normal weight: to maintain health, as well as track the process of losing weight or, conversely, gaining weight.

How to calculate your ideal weight: description of calculation methods and formulas

Calculation using Broca's formula

This calculation method is incredibly popular, thanks to taking into account not only a person’s height, but also the constitutional structure of a person.
The initial data required for the calculation is human height.

If height is less than 165 cm, then the following formula applies:

Height - 100 = normal weight.

If height ranges from 165 to 175 cm, then the following formula applies:

Height - 105 = normal weight.

If height is more than 175 cm, then the following formula applies:

Height - 110 = normal weight.

When calculating using this formula, you should also take into account your body type:

Thin-boned or asthenic.
If you use this particular method, then make the calculation, taking into account the asthenic build of your body.
To do this, you need to measure the circumference of the wrist and make sure that for the asthenic type this figure is less than 16 cm.
It is necessary to adjust as follows: 16 cm – 10% = normal.
For a normasthenic body type, use normal values from 16 to 18 cm.
No adjustment required.
If your body type is hypersthenic or broad-boned, then your wrist circumference will be more than 18 cm.
Adjustment: 18 cm + 10% = normal.

The article will describe body types in more detail below.

Carrying out calculations using the Lorentz formula

One of the simplest options for calculating your weight norm is this formula. But the result obtained after calculation according to Lorenz is only a guideline, since it does not take into account an important factor - physique.

To calculate your ideal body weight using this formula, you only need to know your height. Let's give an example of a calculation using the Lorentz formula, where height will be 176 cm:

Step 1: Height 176-100=76

Step 2: Height 176-150/2=13

Normal weight: 76-13=63.

The ideal weight for a height of 176 cm would be 63 kg.

Lorentz formula:

X= height – 100

Y = height – 150/2

Ideal weight = X-Y

Calculation using Bongard's formula

More suitable for calculating normal weight in men. This formula is not complicated, but it takes into account a very important factor of a person’s physique.

To calculate body weight using this method, you need to know the height and volume of the chest.

The formula looks like this:

IV = Height * Breast Volume/240

The history of the appearance of other well-known formulas for calculating ideal body weight

The above formulas for calculating ideal weight are not the only ones. Questions of this nature have interested people at all times.

The first formula that was created in 1871 was Broca's formula.
According to the method of this scientist, it was proposed to calculate body weight by subtracting 100 from height, for example, height 166 cm. 166-100 = 66. Normal weight for this height would be 66 kg.
Later in 1964, the Humvee scientist offered to calculate the weight of anyone, taking into account the height and initial weight in kilograms for a man and a woman.
Humvee believed that a man should take 48.1 kg as a starting point and add 1.1 kg for every centimeter of height if he is over 152 cm.
For women (girls), the starting point will be a weight of 45.4 kg.
And an increase of 0.9 kg after each cm above 152 cm.
The scientist Devine, who proposed his method in 1974, adhered to approximately the same calculation system.
If you calculate according to the formula of this scientist, you need to take the starting point in the weight of a man - 50 kg, a woman - 45.5.
After this, for every cm of height above 152 cm, it is necessary to add 0.9 kg for men and 0.9 kg for women.
The calculation created by Robinson is similar in its calculation to the methods proposed by scientists a little earlier.
The scientist suggested taking the following numbers only as the initial body weight: for men – 52 kg; women – 49 kg.
And also for every centimeter over 152 cm add: for men 0.75 kg, and for women: 0.7 kg.
The formula developed by Hammond in 2000 suggests using the same system for calculating weight.
The initial weight for a man will be 48 kg, and for a woman 45 kg.
The height reference bar will be 150 cm.
If the height is over 150 cm, then for each subsequent cm of height a man needs to add 1.1 kg, and a woman 0.9 kg.

How can a person understand if there are extra pounds?

When talking about ideal body weight, it is important to first decide whether you are overweight at all? To determine this, you need to know your BMI (body mass index).

It is thanks to the BMI indicator that you can determine whether you are underweight or overweight.

Ideal height to weight ratio - what is it?

Based on the foregoing, it can be understood that “ideal weight” is a ratio of many indicators.

All factors are very important:

height;
body type;
age.

That is why we can say that the ideal weight is a certain indicator, that figure of “comfortable weight” from an already defined norm.

Is it worth losing weight

How should a person who wants to lose weight motivate himself? You need to determine for yourself that it is impossible to lose weight by mocking yourself with hunger strikes and endless exercise.

Sooner or later, excess physical activity will lead to disgust at the mere thought of having to do exercise, and a hunger strike will not lead to weight loss, but to its subsequent repeated gain, because no one can live without food.

That is why you need to determine your excess weight in kilograms, choose the appropriate physical activity and be sure to eat.

Nutrition is an important condition when losing weight!

Nutrition may be different, but for health and systematic loss of excess body weight and subsequent maintenance of a “comfortable weight” you need to eat right!

Before losing weight, a literate person must make sure that he really needs it and that the problem is not far-fetched. And for this you need to know how to calculate excess weight. This will help determine exactly how many kilograms you need to lose to achieve ideal parameters for your gender, height and age. The only problem is that there are a huge number of calculation formulas, and no one can say for sure which of them is the most accurate. Scientists say that none of them claims to be the best: each has shortcomings.

Quetelet's classic formula

A universally accepted method for calculating a person’s excess weight is Quetelet’s formula. It is approved and recommended by such an authoritative organization as WHO. That's why most people use it. Allows you to find BMI - body mass index (in the West this is the abbreviation BMI - Body Mass Index).

Formula for calculation: I=M/H 2, where:

I - body mass index;
M - current weight in kilograms;
H - current height in meters.

M=74;
H=1.6;
calculate the square of height: 1.6x1.6=2.56;
it turns out I = 74:2.56 = 28.91.

Note. Here and throughout the text, all examples of calculations will be given based on these data: our conventional little man weighs 74 kg with a height of 1 m 60 cm. His other parameters (age, gender, build, wrist size) will vary. This makes it more convenient to compare the results obtained at the end and draw a conclusion about the “accuracy” of the proposed formulas and methods.

According to the official WHO table, the BMI norm ranges from 18.5-24.9 (inclusive). Overweight the corridor is considered to be 25-29.9, which is where the figure obtained in our calculation example (28.91) fell. Indicators starting from 30 already refer to obesity.

Despite the fact that the BMI formula is recognized by the WHO itself, it is often criticized because it is not accurate. Firstly, Quetelet (a Belgian statistician and sociologist) developed it back in 1869. It's simply outdated. Secondly, it does not take into account the age and constitution of the human body, which means it cannot be recognized as an ideal calculation.

WHO recognizes the imperfection of this approach, but is in no hurry to abandon it. They adjusted the normal BMI based on age and gender:

If the BMI is higher than the indicators given in the table, this indicates the presence of excess body weight.

Tables

Those who are not good with mathematics and do not like calculations can determine excess weight in other ways. Firstly, to do this, just find online calculators, enter your data in special boxes, click the “calculate” button and get a ready-made answer. Secondly, you can find tables of correspondence between body weight and parameters such as gender, height or age.

Height and weight table

Example. Our conventional little man with a height of 160 cm and a body weight of 74 kg falls into the category of those who need to get rid of extra pounds. If this is a woman, she will have to lose at least 18 kg (her optimal parameters are 50-56 kg). If a man, then by 14 kg (for him the ideal corridor is indicated as 55-60 kg).

Table by height and age

Example. If our conventional male person is 20 years old, then he needs to lose 11 kg; and if 60, then only by 6.

Table for calculating excess weight depending on body type

According to their physique, people are divided into 3 types, and the parameters of ideal and excess weight can also depend on this. Your wrist size will help you determine who you are:

For asthenics:

the neck is long, thin;
the shoulders are narrow;
the chest is flat, narrow;
limbs are long;
elongated face;
thin nose;
muscles are weak;
the tendency to be overweight is minimal.

For normosthenics:

slender legs;
waist is thin;
harmonious figure;
average height.

For hypersthenics:

the bones are heavy and wide;
the chest is voluminous and short;
broad shoulders;
shortened limbs;
below average height;
the tendency to be overweight is high.

After this, you can determine whether you are overweight using the tables:

For men

For women

If you and your body type do not fit into the corridor of ideal body weight, then you still have a problem with excess weight. How important this is can be seen in the example of our little man. If this is a hypersthenic woman, she will have to lose at least 13 kg, if she is normosthenic, then by 18, and if she is asthenic, then by all 23. Agree: the difference is significant.

Such tables are convenient because they do not require complex mathematical calculations, which are easy to make mistakes.

Broca's method

Paul Brocq (French surgeon, anatomist, ethnographer, anthropologist) in the 19th century proposed a special formula by which excess weight can be calculated. Today, in terms of popularity, it is only slightly inferior to the Quetelet method. It is based on the body type, which was already mentioned above.

H – 100 (if H< 165 см);
H – 105 (if H = 166–175 cm);
H – 110 (if H > 175 cm).

After that, to calculate excess weight, we use your body type:

asthenics reduce Broca's index by 10% and achieve their ideal body weight;
hypersthenics increase it by 10%;
normosthenics leave the result unchanged.

Calculation example. If our conditional little man:

asthenic: 160–100–10%=54; then he will have to lose 20 kg;
hypersthenic: 160–100+10%=66; then he has 8 kg in excess;
normosthenic: 160–100=60; then he needs to lose 14 kg.

The Broca method does not work for athletes, pregnant women or children.

other methods

Many scientists have tried to develop a method by which it would be possible to calculate the ideal weight and determine the number of extra pounds. Let us give examples of only the most famous ones.

Lorenz

A formula from the last century from the Danish physicist Hendrik Anton Lorentz. To calculate excess weight, you must first determine your ideal weight.

Extended Lorentz formula: H (height in centimeters)–100–(H (in centimeters)–150):2.

Example: 160–100–(160–150):2=55.

Brief: H (in centimeters): 2–25.

Example: 160:2–25=55.

Now for our conventional little man we can calculate how much excess weight he has: 74–55 = 19 kg.

Borngart

V=75;
160 x 75:240=50.

Conclusion: 20 extra kilograms were discovered.

Mohamed

Example: 160 2 x 0.00225 = 57.6.

Conclusion: you need to lose 16.4 extra pounds.

Mohamed's technique was developed in 2010. Many scientists consider it not only the most innovative, but also one of the best.

Breitman

For example: 160 x 0.7–50=62.

Conclusion: 12 kg in excess.

Monneroth-Dumain

For example:

V wrist=17 cm;
(160–100+(4 x 17)):2=64.

Conclusion: you need to get rid of 10 kg.

Brok–Bruksht

for a woman: H (in centimeters)–100–(H (in centimeters)–100):10;
for a man: H (in centimeters)–100–(H (in centimeters)–100):20.

Calculation example:

For women: 160–100–(160–100):10=54.

Conclusion: we are losing 20 kg.

For men: 160–100–(160–100):20=57.

Conclusion: we are losing 17 kg.

Kreff

Odds:

0.9 at V wrist< 15 см;
1 with V wrist = 15-17 cm;
1.1 for wrist V > 17 cm.

Calculation example:

V wrist=17 cm;
age=45 years;
(160–100+(45:10)) x 0.9 x 1=58.05.

Conclusion: we are losing 15.95 kg.

Davenport

Calculation example:

convert body weight to grams: M=74 kg=74,000 g;
74,000:160 2 =2.89 (there is excess weight if this indicator exceeds 3).

Conclusion: the parameters are close to the critical level.

Potton

Ideal weight formula for men: H (in centimeters) – 100 – H (in centimeters): 200.

Example: 160–100–160:200=59.2.

Conclusion: you will have to lose 14.8 kg.

Formula for women: H (in centimeters)–100–H (in centimeters):100.

Example: 160–100–160:100=58.4.

Conclusion: women will have to get rid of 15.6 kg.

Korovin

thickness of the skin fold near the third rib;
thickness of the skin fold at the level of the navel.

if the thickness of the skin fold near the third rib is more than 1.5 cm, this is a sign of excess weight;
if the thickness of the skin fold at the navel level is more than 2 cm, this also indicates the presence of extra pounds.

Devin

In 1974, Dr. Devin developed a formula that was intended to correctly calculate the required dosage of medications for a patient. But over time, it gained wide popularity and began to be used to determine ideal body weight. By the way, most online calculators work precisely on its basis.

Formula for men: 50 + 2.3 x (H (in inches) - 60).

50+2.3 x (62.99–60)=57.

Conclusion: you need to lose 17 kg.

Formula for women: 45.5 + 2.3 x (H (in inches) - 60).

Calculation example:

convert height to inches: H=160 cm=62.99 inches;
45.5+2.3 x (62.99–60)=52.

Conclusion: you need to lose 22 kg.

Robinson

This is an improved Devin formula, which, according to many, allows you to get a more accurate result.

Formula for men: 52 + 1.9 x (H (in inches) - 60).

Calculation example: 52+1.9 x (62.99–60)=58.

Conclusion: we remove 16 extra kilos.

Formula for women: 49 + 1.7 x (H (in inches) - 60).

Calculation example: 49+1.7 x (62.99–60)=54.

Conclusion: 20 extra pounds are gained.

Taton

Formula: H (in centimeters)–(100+(H (in centimeters)–100):20).

Calculation example: 160–(100+(160–100):20)=57.

Conclusion: we are losing 17 kg.

For reference: Jan Taton is a Polish researcher who has been studying the problem of excess body weight throughout his life. I developed my own diet.

Noorden

Calculation example: 160 x 420: 1000 = 67.2.

Conclusion: ballast is 6.8 kg.

Cooper

Formula for men: 0.713 x H (in centimeters) – 58.

Calculation example: 0.713 x 160–58=56.

Conclusion: 18 kg in excess.

Formula for women: 0.624 x H (in centimeters) - 48.9.

Calculation example: 0.624 x 160–48.9=51.

Conclusion: 23 excess kilograms.

Gabbs

Calculation example: (160–150) x 4:5+55=63.

Otto

Formula for men: Broca's index - (Broca's index - 52) x 1:5.

Calculation example: 60–(60–52) x 1:5=58.

Conclusion: you need to minus 16 kg.

For women: Broca's index - (Broca's index - 52) x 2:5.

Calculation example: 60–(60–52) x 2:5=57.

Conclusion: minus 17 kg.

Dukan

If you need to calculate excess weight according to Dukan, for (you can familiarize yourself with it) it is extremely important, just find an online calculator on numerous sites dedicated to this method of losing weight. It takes into account:

age;
body type;
height;
muscle mass.

If we analyze the data obtained during calculations using different formulas, the scatter is quite large. This once again proves that the ideal technique has not yet been developed.

Bonus for men: John McCallum's technique

John Dennis McCallum is a famous American sports columnist and writer of the mid-twentieth century. In his bestseller “The Key to Success,” he offers a separate formula by which young men (aged 18 to 35 years) can not so much calculate their excess weight as correct their body proportions. His technique is based on wrist circumference:

wrist circumference x 6.5 = chest circumference (CH);
85% OG = pelvic volume;
70% OG = waist;
53% OG = hips;
37% OG = neck;
36% OG = biceps;
34% OG = drumstick;
29% OG = forearms.

The McCallum Method is also called the bodybuilder's formula. Men for whom it is important not only to lose weight and gain weight muscle mass, but also to correctly distribute it over the body so that it is embossed and beautiful, these calculations are a real godsend.

Now all these formulas are used only at home and are recommended for those who have overweight does not exceed 10 kg. In other cases, experts recommend contacting them with this problem. Since 2000, a new measurement method has been tested and used in clinics as an alternative to BMI. It was called the body volume index (BVI - Body Volume Index). It is more accurate because it is the result of a three-dimensional scan.
