The formula for a man's body weight relative to height. How to calculate the normal weight of a person? How to determine if a person is overweight: ways to measure body composition

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 permissible weight body

Height, cm

20–29 years old

30–39 years old

40–49 years old

50–59 years old

60–69 years old

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 have excess weight, not whether 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 obtained should also be compared with the table, however, in this option, 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 it 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 should 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 indisputable plus of BMI is that it does not indicate a mythical ideal, but estimates real weight and height.

Before losing weight, a competent person must make sure that he really needs it and 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 in order 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 one is the most accurate. Scientists say that none of them claims to be the best: each has flaws.

The classic Quetelet formula

The Quetelet formula is a universally recognized way of calculating a person's excess weight all over the world. It is approved and recommended by such an authoritative organization as WHO. That is why most people use it. Allows you to find BMI - body mass index (in the West it is an abbreviation of BMI - Body Mass Index).

Formula for calculation: I \u003d M / H 2, where:

  • I - body mass index;
  • M - current weight in kilograms;
  • H - height in meters at the moment.
  • M=74;
  • H=1.6;
  • we calculate the square of growth: 1.6x1.6 \u003d 2.56;
  • it turns out I \u003d 74: 2.56 \u003d 28.91.

Note. Hereinafter, throughout the text, all examples of calculations will be given based on these data: our conditional little man weighs 74 kg with a height of 1 m 60 cm. The rest of his parameters (age, gender, physique, wrist size) will vary. So it is more convenient at the end to compare the results obtained 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 is considered a corridor of 25-29.9, where the figure obtained in our calculation example (28.91) fell. Indicators starting at 30 are already obese.

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 already in 1869. She is simply outdated. Secondly, it does not take into account the age and constitution of the structure of the human body, which means that 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 according to age and sex:

If the BMI turned out to be higher than the indicators given in the table, this indicates the presence of overweight.

tables

Those who are not friends with mathematics and do not like calculations can determine excess weight in other ways. Firstly, for this it is enough to find online calculators, enter your data in special boxes, click the "calculate" button and get a ready 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 conditional 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 conditional male man is 20 years old, then he needs to lose weight by 11 kg; and if 60 - then only 6.

Table for calculating excess weight depending on the physique

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

In asthenics:

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

For normosthenics:

  • legs are slender;
  • the waist is thin;
  • the figure is harmonious;
  • growth is average.

For hypersthenics:

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

After that, you can determine whether there is excess weight, according to the tables:

For men

For women

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

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

Brock's method

Paul Brock (French surgeon, anatomist, ethnographer, anthropologist) in the 19th century proposed a special formula by which to calculate excess weight. Today, in its popularity, it is only slightly inferior to the Quetelet method. It is based on the type of physique, which has already been 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 the excess weight, we use our body type:

  • asthenics reduce Broca's index by 10% and get 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 an excess of 8 kg;
  • normosthenic: 160–100=60; then he needs to lose 14 kg.

Broca's method does not work for athletes, pregnant women and 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's take only the most famous as an example.

Lorenz

A formula from the last century from the Danish physicist Hendrik Anton Lorenz. To calculate overweight, you must first determine the ideal.

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

Example: 160-100-(160-150):2=55.

Short: H (in centimeters): 2–25.

Example: 160:2–25=55.

Now, for our conditional little man, you can calculate how much excess weight is in him: 74–55 \u003d 19 kg.

Borngart

  • V=75;
  • 160 x 75:240=50.

Conclusion: 20 extra pounds were found.

mohammed

Example: 160 2 x 0.00225=57.6.

Conclusion: you need to lose 16.4 extra pounds.

Mohammed'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: in excess of 12 kg.

Monnerot-Dumine

For example:

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

Conclusion: you need to get rid of 10 kg.

Brok–Bruksht

  • in 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:

Women: 160–100–(160–100):10=54.

Conclusion: lose weight by 20 kg.

For men: 160–100–(160–100): 20=57.

Conclusion: losing weight by 17 kg.

Kref

Odds:

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

Calculation example:

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

Conclusion: losing weight by 15.95 kg.

Davenport

Calculation example:

  • we translate body weight into grams: M=74 kg=74,000 g;
  • 74 000:160 2 \u003d 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 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

  • the thickness of the skin fold near the third rib;
  • thickness of the skin fold at the level of the umbilicus.
  • if the thickness of the skin fold near the third rib is more than 1.5 cm, this is a sign of overweight;
  • if the thickness of the skin fold at the level of the navel 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 drugs for a patient. But over time, it gained wide popularity and began to be used to determine the ideal body weight. By the way, most online calculators work 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 weight by 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 improvement on Devin's formula, which many people say is more accurate.

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

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

Conclusion: remove 16 extra pounds.

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

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

Conclusion: gaining 20 extra pounds.

Taton

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

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

Conclusion: losing weight by 17 kg.

For reference: Jan Taton is a Polish researcher who has dealt with the problem of overweight throughout his life. Developed my own diet.

Noorden

Calculation example: 160 x 420: 1000 = 67.2.

Conclusion: the 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: in excess of 18 kg.

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 - (Brock'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 - (Brock'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 Dukan's overweight, for (you can read it) it is extremely important, just find an online calculator on numerous sites dedicated to this weight loss method. It takes into account:

  • age;
  • body type;
  • height;
  • muscle mass.

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

Bonus for Men: The John McCallum Method

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) can not only calculate their excess weight, but adjust body proportions. His technique is based on the circumference of the wrist:

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

McCallum's technique is also called the bodybuilder's formula. Men for whom it is important not only to lose weight and build muscle mass, but also to properly distribute it throughout the body so that it is embossed and beautiful, these calculations are a real find.

Now all these formulas are used only at home and are recommended for those whose 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 as it is the result of a 3D scan.

Do you know your ideal weight? Worried about health? Do you want to maintain optimal body proportions? In order to start changing your lifestyle, go in for sports or introduce into your diet healthy foods, you need to calculate the weight by height and age. This will be the starting point, a kind of guideline in developing a weight loss program, selecting a set of exercises or compiling the “right” menu.

Calculating the ideal weight for women on a calculator from the site is a way to determine the norm of body weight, which will help you always keep fit and monitor its changes.

BMI: what is it and why count it

In the middle of the 19th century, practitioners and doctors of medical sciences noticed that the ratio of height and weight affects the state of health. And in 1869, Adolf Quetelet (a well-known scientist at that time) named it "body mass index" (BMI). It is designed to determine the correspondence of these parameters.

It is calculated for both men and girls according to one formula:

where M is the weight indicated in kilograms; P - height squared. Take the value in meters.

Let's calculate the body mass index of a representative of the weaker sex with a height of 167 cm and 74 kg, translate the height from centimeters into meters: 167 cm \u003d 1.67 m. Then we square this value: 1.67 * 1.67 \u003d 2.8. We substitute the numbers in the formula: M \u003d 74 / 2.8 \u003d 26.4.

The BMI for this woman would be 27.4. What gives this value? By itself, it is just a number, but with a body mass index interpretation table, it is useful knowledge. By comparing it with the indicators available in it, you will determine how much the current weight corresponds to the norm.

Body mass index (BMI) What does it indicate Recommendations
>40 3 degree of obesity It is worth correcting the situation in the near future. Since the risk of acquiring a particular disease (hypertension, for example) is increased. Seek help from a nutritionist.
35 to 30 2 degree of obesity There may be problems with the cardiovascular and other body systems.
30 to 25 1 degree of obesity There is a chance to quickly and without consequences for the body to throw off extra pounds, which will help to avoid illness.
24.99 to 18.5 norm Weight in the optimal range for your age and height. Try to keep the mass in this limit and the chances of staying healthy will increase significantly.
18.5 to 16 and below underweight Increase the amount of food you eat. Sign up for a consultation with an endocrinologist. Review your diet.

The concept of "ideal weight" is a generally accepted framework, the limits of which become the designation of the optimal height / all ratio. We are all different, and the body weight of a person depends on such factors:

  1. diet;
  2. physique;
  3. lifestyle;
  4. nationality and others.

Therefore, the ideal weight is an average standard. It is calculated on the basis of a large amount of information that has been obtained as a result of studying these people. So a man of a strong physique will weigh 2-3% higher than that of a thin one. And a thin woman is 3 - 5% less than a lady with magnificent forms.
Recommended.

The Internet is full of various articles and tables on determining the optimal ratio of weight and height. But all of them are very, very conditional, since they do not take into account many factors: age, gender and physiological features person. Therefore, excess fat should be assessed not only by the conditional ratios presented in this table, but also by appearance, thickness of the skin and a number of other factors. With the same height and weight, one person may look full, the other - completely normal.

objective parameter perfect body is the percentage of fat and musculoskeletal tissue. For men, the norm is 9 - 15% fat of 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 shows well the amount of fat in the body, but does not indicate how fat is distributed, in other words, it does not give a visual-aesthetic picture. But you can check your body for ideality by another formula.

The distribution of body fat is determined by the ratio: waist circumference (at the level of the navel) divided by the circumference of the buttocks.

  • Norm for men: 0.85
  • For women: 0.65 - 0.85.

Does age affect height-to-weight ratio?

The answer is unequivocal. Yes, of course it does. It has been proven that the weight of a man and a woman should gradually increase with age - this is a normal physiological process. Kilograms, which some people consider "superfluous", in fact, they may not be. You can use the formula to determine the optimal weight depending on age.

P is height in this case, and B is 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. It takes into account the ratio of height, weight, body type and age of a person.

Brock's formula for people under 40 years old 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 THREE 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).

Solovyov index body type Typical for this body type
for men for women
18-20 cm 15-17 cm normosthenic (normal) the physique is distinguished by the proportionality of the main dimensions and their correct ratio
over 20 cm over 17 cm hypersthenic (broad-boned) In people with a hypersthenic (wide-boned) body type, the transverse dimensions of the body are much larger than in normosthenics and especially asthenics. Their bones are thick and heavy, their shoulders, chest and hips are wide, their legs are short.
less than 18 cm less than 15 cm asthenic (thin-boned) 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 chest circumference is equal to the thigh circumference.
  5. For the neck circumference, you need to take 37% of the chest circumference.
  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 circumference of the forearm should be equal to 29% of the circumference of the chest.

But not all physical data will exactly correspond to these ratios, the numbers have an average, average value.

A few more options for the ratio of height and weight

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

Ecology of life. There are different formulas for determining the optimal ratio of weight and height. But all of them are very, very conditional, since they do not take into account many factors ...

There are different formulas for determining the optimal ratio of weight and height. But all of them are very, very conditional, since they do not take into account many factors: age, gender and physiological characteristics of a person. Therefore, excess fat must be assessed not only by the conditional ratios presented in this table, but also by appearance, skin thickness and a number of other factors. With the same height and weight, one person may look full, the other - completely normal.

The objective parameter of an ideal body is the percentage of fat and musculoskeletal tissue. For men, the norm is 9 - 15% fat of 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.

Obesity III degree

The Quetelet index shows well the amount of fat in the body, but does not indicate how fat is distributed, in other words, it does not give a visual-aesthetic picture. But you can check your body for ideality by another formula.

The distribution of fat throughout the body is determined by the ratio: waist (at the level of the navel) divided by the volume of the buttocks.

  • Norm for men: 0.85
  • For women: 0.65 - 0.85.

Does age affect height-to-weight ratio?

The answer is unequivocal. Yes, of course it does. It has been proven that the weight of a man and a woman should gradually increase with age - this is a normal physiological process. Kilograms, which some people consider "superfluous", in fact, they may not be. You can use the formula to determine the optimal weight depending on age.

P - in this case, height, and B - age in years. Body weight \u003d 50 + 0.75 (P - 150) + (B - 20): 4

As you can see, there are many ways to calculate the optimal ratio of your height and body weight, depending on a variety of factors. But no matter how you do the calculations, the main thing is that your weight is COMFORTABLE for yourself. So that you can easily and freely feel in your own body, love yourself and enjoy life to the fullest! - without getting depressed from the fact that during the calculations you (and suddenly!) found out an “overabundance” or “lack” of kilograms.published
