How to calculate ideal weight

For many centuries of existence, mankind has created enough formulas to help you find out your ideal weight. All of them are great for determining the boundaries of underweight and overweight, but they differ in complexity and the set of necessary initial data. The simplest and at the same time informative is the Lorentz formula, which allows you to calculate the ideal weight by height. The people called it the "dream formula".

The Lorentz method was developed in 1929. Suitable for people over 18 years old, height from 140 to 220 cm. It has two options - for women and for men. An undoubted advantage is obtaining indicators close to the results of more complex and time-consuming calculation methods.

For woman

The only indicator that you need to know to calculate the ideal weight using this formula is height in centimeters. It is not difficult to make accurate measurements of growth: you need to stand with your back to the wall, make a mark at the level where the top point of the head (crown) will be located and measure the result with a centimeter tape.

Calculations of ideal body weight are made according to the following formula: (height in cm - 100) - (height in cm - 150) / 2.

Example: (170-100) - (170-150)/2= 70-20/2=60.

The ideal weight for a 170 cm tall woman is 60 kg.

For a man

The Lorenz method is quite informative for men as well. Again, in order to determine the norm of its own weight, it is enough for a man to know his height in centimeters exactly. The calculation goes like this: (height in cm - 100) - (height in cm - 150) / 4.

Example: (180-100) - (180-150) / 4 = 72.5.

The norm for a man with a height of 180 cm is 72.5 kg.

How to find out the normal weight of a child

Since there are formulas for calculating weight taking into account age, it is possible to determine the norm for small child and teenage girls and boys. Formulas for children are different from adults, since with age there are some changes in the rate of metabolic processes. You can calculate the normal weight of a child using a free one.

Making such calculations is no less important than for an adult, because by identifying the ideal weight of a teenager, you can adjust his diet and prevent weight gain in the future.

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

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

In order to more objectively assess your weight, there are calculation formulas excess weight. They are also not perfect, they have a number of drawbacks. But they allow you to reconsider your view on the issue of excess weight. You will find the most famous formulas for calculating ideal weight in this article.

Determination of ideal body weight

The ways we talk about are different from each other. And to some extent reflect the evolution of methods for calculating the ideal body weight. From the authoritarian method of Lorenz, which is suitable only for young girls. Before Broca's formula, taking into account body type and calculation formulas for age and height.
If you are curious, read the article with a pencil and paper in hand. But do not be strict about the resulting numbers. Not a single formula can describe the individuality, way of life, state of health and feelings in one or another weight of a particular woman.

First way. Lorentz method

The advantage of the Lorentz method: calculates the weight rate for those girls who are always 18. But seriously, this is one of the toughest methods that you should not be guided by.

The disadvantage of this method it is believed that it only works for girls, but not for guys. Also, you can not use it if a woman is taller than 175 cm.

According to this method, calculate ideal mass bodies in girls should be like this:

1. Measure your height in centimeters.
2. Subtract 100 from it.
3. The second action will be subtracting from the height of 150 centimeters.
4. Determine the difference between the first and second results.
5. The resulting units are divided in two.

This is how the formula for estimating body weight in a female looks like: (P - 100) - (P - 150) / 2.

For instance: the girl has a height of 170 cm, we calculate: (170 - 100) - (170 - 150) / 2 \u003d 70 - 20/2 \u003d 60 kg.

The second way. Quetelet index

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

The disadvantage of the formula is the inability to apply it to adolescents and the elderly. Also, you should not count on the objectivity of the method with very low or very high male and female growth. The method is valid for representatives of the stronger sex 1.68-1.88 meters, and the weak - 1.54-1.74 meters. He “lies” to pregnant, lactating mothers, athletes.

Important! The calculation of the correct weight norm begins with the calculation of BMI (body mass index).

Often, BMI is used by doctors to determine if there is obesity or dystrophy.

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

1. Find out the mass of a person's body in kilograms using scales.
2. Measure height in meters.
3. The first indicator is divided by the square of the second.
4. They calculate and find their BMI in the table.
5. Know the result.

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

Body mass index		Human weight parameters
18 to 25 years old	26 to 46 years old
> 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	1 degree of obesity
Up to 35	Up to 36	2 degree of obesity
up to 40	up to 41	3 degree of obesity
40 and more	41 and more	4 degree of obesity

For instance: A 24-year-old girl has a height parameter 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 were 2 years older, then her parameters corresponded to her age.

The third way. Brock's formula

Advantage: the technique of how to correctly determine the excess weight of a person according to Brock is 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:

1. The number 110 is subtracted from the height in centimeters if the person is under 40 years old.
2. The older the man or woman, the more he (she) will weigh. After the age of forty a person, his parameter is calculated as follows: the number 100 is subtracted from height.
3. Also, a correction in the calculations is 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 weight norm for a woman of thirty years as follows - 110 units are subtracted 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 hypersthenic - then 57 + 5.7 = 62.7 kilograms.

Fourth way. Nagler's method

The advantage of the Nagler method The fact is that if you have data on growth, you can calculate the ideal number of kilograms for a girl.

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

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

Example: 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 - it 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 does not reflect their body type in any way.

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

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

Example: a woman is 42 years old, and her height is 168 cm. Find 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 smartness.

What is your favorite way to calculate your ideal weight?

Imagine a picture: wake up in the morning, take a shower, have breakfast. And when the time comes to put on your favorite jeans, we realize with horror that we can’t fasten them - the stomach interferes. We climb under the sofa, find dusty floor scales, get up on them and ... A familiar story, right?

Whatever figure is displayed on the scales, frustration and depression are received - jeans are not to be worn now. What to do? You can just score. Throw your pants in the trash or shove them into the farthest corner of the chest of drawers - let them lie there until better times. And you can go the other way - throw off a couple of other extra pounds - maybe the trousers will fit.

The second option is more difficult - you need to do something, spend time, make efforts. However, we clench our will into a fist and decide to lose weight. But before starting, another question arises - what to strive for, how many kilograms you need to lose, so that it is completely good: both pants so that they fit, and breathe easier, and on the beach so that in the summer it would not be a shame to get out. We are thinking, trying to figure it out - how to calculate your ideal weight?

It turns out that the ideal (correct) weight is an abstract concept, and it denotes the average value obtained on the basis of a set of given physiological parameters of a person, such as height, age, gender characteristics, body features. But the state of health, level physical activity, the percentage of fat mass in relation to muscle mass and other individual indicators of a single person are not taken into account here.

This means that it will not be possible to find the exact value of your weight using known formulas. However, we will get an approximate guideline that we can rely on when reducing or gaining body weight.

The most famous types of weight calculation by formulas:

• Calculation of weight by height
• Calculation of weight by age and height
• Calculation of weight by BMI (body mass index)

Calculate weight by height

A simple method known more as Brokk's formula. The simplified version looks like this:

• For women: Ideal weight = Height (cm) - 110
• For men: Ideal weight = Height (cm) - 100

Example: the normal weight of a man with a height of 180 cm is 80 kg, and for a woman with a height of 170 cm - 60 kg

The modern version of the same formula looks a little different, but is considered more accurate:

• For women: Ideal weight = (Height (cm) - 110) * 1.15
• For men: Ideal weight = (Height (cm) - 100) * 1.15

Example: the normal weight of a man with a height of 180 cm is 92 kg, and for a woman with a height of 170 cm - 69 kg

Calculate weight by age and height

The following weight determination method is not a calculation formula. This is a ready-made table with which you can calculate the correct weight by age. And if the previous version gives an approximate norm of a person’s body weight, then the Egorov-Levitsky table, as it is also called, displays the maximum allowable weight value, the excess of which is considered unacceptable for a given height and age group.

All you need to know is your height, age and actual weight. Look for the intersection of these parameters in the table and understand how far you are from the maximum allowable value. If the figure in the table is higher than your existing weight, it’s good, if it’s lower, there is reason to think about the gym and dietary restrictions.

Example: A woman with a height of 170 cm, 35 years old, weight 75 kg. Crossing over the table shows the maximum weight value of 75.8. A woman is one step away from this value. Therefore, close control of body weight is needed, otherwise it is possible to go beyond the permissible limits.

Calculate weight by BMI (Quetelet body mass index)

table for calculating the optimal weight by Quetelet's body mass index

With the help of the Body Mass Index, you can find out in which predetermined range the person's weight is at the current moment: deficiency, normal or obesity (all BMI values ​​are shown in the table).

BMI is calculated using a formula that uses baseline height in meters and weight in kilograms. The formula looks like this: KMT = weight in kilograms: (height in meters * height in meters).

Example: a man with a height of 185 cm (1.85 m) and a weight of 88 kg will have a BMI \u003d 88: (1.85 * 1.85) \u003d 27.7. We are looking for a value in the table and we understand that the index is in the range of Overweight (pre-obesity).

Important point: calculation correct weight according to BMI does not take into account gender and age-related changes in the body.

Conclusion

It is important to remember, whichever method of calculating the correct weight you choose, the result of the calculations should not be taken as an absolute truth. All figures will be approximate and indicative. And jeans from these calculations still won't fit. So dumbbells in your hands, legs in sneakers, a lock on the refrigerator and forward - towards the result.

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 used a simple formula- from height in centimeters, men subtract 100, 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. On the this moment there are formulas by which you can find out BMI not only by Quetelet, but also by Brock, by Humvee, by Kref and by 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 norms in different time were different. V last 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. BMI of lean individuals with narrow shoulders and chest should be less than the indicators 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 body fat, 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 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 doses. 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 while absolutely normal weight leading to anorexia.

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

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 will be able to calculate body mass index based on age by different formulas or display 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 representatives fair half 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 considering and trying to achieve best results. Obesity does not have a favorable effect on general well-being and on the state of human health. Excess weight leads to hypertension, cardiovascular disease, diabetes and joint disease. Therefore, you should take action and get rid of extra pounds.

On the other hand, it happens that the BMI is within the normal range, and the body looks flabby and by no means young. In this case, you should not be proud of the results of the check and do not care about the figure. Attention should be paid to sports, or at least increased physical exercise 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.
