To lose weight or not to lose weight: how to determine if you are overweight? How to define overweight.

Here, on the radio, some very chief doctor spoke very seriously about sores and the dependence of these sores on excess weight. I never listen to illnesses at all, but I was too lazy to switch here, and it was just an excerpt from the interview. This doctor touched on two WHO-recognized methods for determining overweight: body mass index and waist / height ratio.

Since he repeated the calculation formula several times, I decided to write a calculator for myself, and it won’t hurt to check your “tummy” before the summer, otherwise they will hang it at the airport like a suitcase. Body mass index is measured as follows: weight in kilograms divided by height in meters squared.

The result is interpreted like this:

My body mass index turned out to be normal, but for Olega-Lassi, the initial data of 176 centimeters with 90 kilograms of weight gave first-stage obesity. This conclusion wildly outraged him, but confused me. Not only is he not fat, he doesn't even have a belly. Where these 90 kg in it come from - I have no idea. I believe that there are exceptions to this technique.

The second method is the waist/height ratio.

The result was predictable: the norm for both, as evidenced by the top photo. Oleg has a waist/height ratio of 51%, which indicates a normal weight.

Sometimes they write that the waist / height ratio is somewhere more reliable (accurate) indicator than BMI, because BMI does not take into account the features of a person’s structure, his gender, the percentage of muscle mass in relation to adipose tissue. I myself know a couple of fat people weighing less than 90 kg.

I give a table of results in order for you to determine whether your waist / height ratio is normal or “someone eats too much” (the ratio is given as a percentage).

Women:
Ratio 35 to 41.9: very thin.
Ratio 42 to 48.9: normal weight.
Ratio 49 to 53.9: overweight.
Ratio from 54 to 57.9: obesity.
Ratio over 58: dangerously obese.

Men:
Ratio less than 35: wasted, underweight.
Ratio 35 to 42.9: very thin.
Ratio from 43 to 52.9. normal weight.
Ratio 53 to 57.9: overweight.
Ratio from 58 to 62.9: obesity.
Ratio over 63: dangerously obese.

These methods seemed to me nothing more than an attempt to classify fat people according to the degree of obesity using mathematics. And to eat, as everyone perfectly understands, you need less.

It is known that in the USSR, a healthy weight for a woman was calculated using the simplest formula, growth minus one hundred. According to her, Baba Klava from the bench at the entrance was declared a woman with an ideal figure. Later, nutritionists slightly changed the formula - "growth minus one hundred and ten", and for ballerinas the formula "growth minus one hundred and twenty" has always worked. If such generalized data does not suit you, read on - we have collected the most interesting, relevant and reflective formulas.

Ideal Weight Calculator

Classification of body types according to Solovyov:

1. Asthenic type: less than 18 cm in men, less than 15 cm in women.
2. Normosthenic type: 18-20 cm in men, 15-17 in women.
3. Hypersthenic type: more than 20 cm in men, more than 17 cm in women.

Cooper formula

Ideal weight for a woman (kg): (height (cm) x 3.5: 2.54 - 108) x 0.453.
Ideal weight for a man (kg): (height (cm) x 4.0: 2.54 - 128) x 0.453.

Lorentz formula

Ideal weight = (height (cm) - 100) - (height (cm) - 150) / 2

For our heroine, the ideal weight will be 25 kg. State?

Kyutla Formula (Body Mass Index)

The Body Mass Index is designed to measure overweight and obesity. BMI is familiar to many.

BMI = weight (kg) : (height (m))2

BMI below 19 - underweight.

• At the age of 19-24 - BMI should be in the range from 19 to 24;
• at the age of 25-34 - BMI should be from 19 to 25;
• at the age of 35-44 - BMI should be from 19 to 26;
• at the age of 45-54 - BMI should be from 19 to 27;
• at the age of 55-64 - BMI should be from 19 to 28;
• over the age of 65 - BMI should be from 19 to 29.

Calculation example:

weight - 50 kg.

height - 1.59 m

BMI \u003d 50 / (1.59 * 1.59) \u003d 19.77 (normal BMI)

Fixed weight-height coefficient

The calculation is based on a fixed coefficient (weight in grams divided by height in centimeters). The table below is for women aged 15 to 50.

Ideal weight formula: (height in cm*coefficient)/1000

Brock's formula

It was this formula, proposed by the French physician Brock more than a hundred years ago, that was used in vulgar calculations. Brock's formula takes into account the physique: asthenic (thin), normosthenic (normal) and hypersthenic (stocky).

Ideal weight formula:

• up to 40 years: height -110
• after 40 years: growth - 100

Asthenics subtract 10%, and hypersthenics add 10%.

So our calculations are:

age - 24 years

height - 159 cm

physique - hypersthenic.

Ideal weight = 53.9 kg.

Brock-Brugsch formula

This is Brock's modified formula for people with non-standard height: less than 155 cm and more than 170 cm.

• Less than 165 cm: ideal weight = height - 100
• 165-175 cm: ideal weight = height - 105
• Over 175 cm: ideal weight = height - 110.

Egorov-Levitsky table

Attention: the table indicates the maximum weight for this height!

Maximum allowable body weight

Our exemplary woman with her weight of 50 kg with a height of 159 cm and an age of 24 years is far from the maximum. And this is good.

Many consider this table to be the most complete and balanced approach to determining the presence of overweight.

Borngardt index (1886)

It also uses chest circumference data.

Ideal weight = height * bust / 240

Robinson formula (1983)

There is an opinion that for men it is incorrect.

For women (height in inches):

49 + 1.7 * (height - 60)

For men (height in inches):

52 + 1.9 * (height - 60)

Miller Formula (1983)

For women (height in inches):

Ideal weight = 53.1 + 1.36 * (height - 60)

For men (height in inches):

Ideal weight \u003d 56.2 + 1.41 * (height - 60)

Monnerot-Dumain formula

This formula takes into account body type, bone volume, muscle mass.

Ideal weight = height - 100 + (4 * wrist)) / 2

Kref formula

This formula takes into account age and body type.

Ideal weight \u003d (height - 100 + (age / 10)) * 0.9 * coefficient

Odds:

• Wrist less than 15 cm - coefficient 0.9
• Wrist 15-17 cm - coefficient 1
• Wrist more than 17 cm - coefficient 1.1.

Mohammed Formula (2010)

Ideal weight = height * height * 0.00225

According to him, the ideal weight of our heroine should be 56.88 (which is a bit much).

Nagler formula

A little too general, Nagler's formula does not take into account your age and current weight at all - only height and gender.

For women (note: height in inches!):

Ideal weight = 45.3 + 2.27 * (height - 60)

For men (note: height in inches!):

Humvee Formula (1964)

Online weight calculators on the Internet usually use it:

Formula for women (height in inches):

Ideal weight = 45.5 +2.2 * (height - 60)

Formula for men (height in inches):

Ideal weight = 48 + 2.7 * (height - 60)

Devin Formula (1974)

Dr. Devin invented it to correctly calculate drug doses. She entered the mass consciousness as an ideal weight calculator later and enjoyed great success. True, there are also disadvantages: for women of small stature, the weight is usually offered very little.

For women (height in inches):

Ideal weight = 45.5 + 2.3 * (height - 60)

For men (height in inches):

Ideal weight = 50 + 2.3 * (height - 60)

It is believed that the ideal weight is the one that you had at 18 years old. It is advisable to keep it for life. But if you have broken away from the ideal over the past 15–20 years or more, you should not strive to return to it at any cost. After all, every 10 years of life, the energy consumption of the body decreases by about 10%. Accordingly, for every 10 years we add about 10% (5–7 kg): first from the same ideal weight, later from the one we have. And you should burn fat carefully, focusing on the same 10%, only in a year. In addition, it is better to strive not for an eighteen-year-old weight, but to calculate your new ideal using one of the medical formulas.

Brocca's formula

Ideal weight for men \u003d (height in centimeters - 100) 1.15.

Ideal weight for women \u003d (height in centimeters - 110) 1.15.

Example: The ideal weight of a woman with a height of 170 cm \u003d (170 - 110) 1.15 \u003d 69 kg.

Surely, this formula will remind many of the old “height minus 100” for men and “height minus 110” for women. It's really an improved version of that old formula. The fact is that the previous version required everyone to be fitness models, did not take into account either age or body type. Therefore, neither people with heavy bones and large muscles, nor women with pronounced hips and breasts could fit into it at all. Therefore, scientists have subjected the old formula of Brokk to processing, and in its current form it looks quite realistic.

Lorenz's dream

The ideal weight of a woman \u003d (height in centimeters - 100) - (height in centimeters - 150) / 2.

Example: The ideal weight of a woman with a height of 165 cm \u003d (165 - 100) - (165 - 150) / 2 \u003d 65 - 15/2 \u003d 57.5. Ideal weight - 57.5 kg!

Please note that this formula was developed only for women and is in no way suitable for the stronger sex. At first glance, it is too demanding on weight compared to Brokk's improved formula and indicates, rather, just the ideal weight when you were eighteen. Nevertheless, it is fully consistent with the body mass index (BMI), so it is quite possible to use it. If you are upset by the proposed numbers, then just forget about it and use a different formula. By the way, for women above 175 cm, it still will not work.

Egorov-Levitsky table

Maximum allowable body weight

Example: A 45-year-old woman weighs 76 kg with a height of 170 cm. This is not much at all, it is less than the maximum allowable!

The medical compilers took into account everything that is possible: gender, age, height. They did not limit only the lower limit of weight. But this is understandable - the table helps to find out if you are overweight, and not if it is insufficient. In our opinion, the most complete and balanced approach to ideal weight.

Quetelet index

Index = weight in grams / height in centimeters.

This is also a method to estimate the already existing weight, close to the BMI method described above. No wonder they have the same author. Here, the result should also be compared with the table, however, in this version, the physique is also taken into account. It can be determined very simply: stand in front of the mirror, pull your stomach in as much as possible and attach two rulers or just your palms to the two lower ribs. They form an angle. If it is rather blunt (more than 90 grams), you have a large physique. If almost straight, the physique is normal. If the angle is sharp, the physique is considered thin.

Example: The weight-height index of a 45-year-old woman weighing 70 kg with a height of 160 cm, a large physique = 70,000 / 160 = 437.5. For her, this is normal weight. And if she were 6 years younger or had a different body type, she would be considered too full!

This formula is respected by the fact that it takes into account many factors: age, and body type. It can be used for any height, you just need to be honest with yourself when assessing your body type. In any case, approaching the upper limit of the tabular index by 5-10 points is a reason to correct your diet and move more.

Quetelet calculation or body mass index (BMI)

Body mass index (BMI): weight in kilograms / (height in meters x height in meters).

This formula evaluates the existing weight and indicates in which direction it should be changed. Recall that to square a number, simply multiply it by itself. Compare the result with the table.

Example: BMI of a woman with a height of 170 cm and a weight of 72 kg \u003d 72 / 1.7. 1.7 = 24.9. She is overweight, she is still far from being obese, but she must at least not gain kilograms, and even better, lose 3–4 kg.

When comparing your weight with BMI, you need to know some features that, as a rule, are not mentioned anywhere. This formula is correct for people of average height (men - 168-188 cm and women 154-174 cm). For those who are shorter, the ideal weight is 10% lower than the "formula", and for those who are tall - 10% higher. In addition, this formula can "lie" when assessing those who exercise five or more times a week. The undeniable advantage of BMI is that it does not indicate a mythical ideal, but estimates real weight and height.

BMI, or body mass index, is an indicator that allows you to assess how much a person's body weight corresponds to his height. It is easy to calculate it. To do this, body weight in kilograms must be divided by height in meters squared.

For example, if you weigh 70 kg and your height is 1 m 65 cm, then your BMI will be 70/1.652 = 25.7 kg/m 2.

To evaluate this indicator, one should refer to the table developed by the World Health Organization.

Advanced: Body Fat Percentage Measurement

In recent years, many doctors have criticized the definition of overweight using body mass index. The fact is that BMI is a very average indicator. It is completely unsuitable, for example, for athletes: they have very developed muscles, due to this they weigh a lot, but this weight cannot be called superfluous. Does not take into account BMI and age or, say, gender characteristics. Meanwhile, over time, it is quite natural for a person to gain body weight within certain limits, and women with the same BMI as men are likely to have more fat.

Therefore, now in addition to determining BMI, body composition analysis is usually prescribed. Excess weight is not an excess of muscles, not water, but namely adipose tissue. That is what needs to be discovered. Paradoxically, such an excess is often observed in people with a normal BMI. Such people also need to adjust their figure: it is not necessary to go on a diet, but it is very worth doing physical education. It will strengthen the muscles in which fat burns.

To find out the percentage of fat allows bioimpedance analysis of body composition. A weak electric current is passed through the body, changing its frequency. Different tissues have different resistance to electricity, and this makes it possible to determine how much body weight is due to muscle mass, which is to bones, and which is to fat. If bioimpedance analysis is not performed at the medical facilities available to you, you can arrange a similar procedure at home. To do this, it is enough to buy an electronic scale with the function of determining fat. The principle of their work is the same, but they are less accurate, for example, they can rank the water contained in the body as fat mass. But for determining the dynamics of weight loss, this is still a good option.

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. No wonder. 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 indicators obtained, 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 shape. You should pay attention to sports or at least increase physical activity in order to put the 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.
