website found 5 ways to calculate the optimal weight used by fitness professionals.

Method 1. Quetelet index

If you know the body mass index, you 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).

The resulting number will be your index. The norm for men is 19-25. For women - 19-24.

Method 2. Volumes

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

The distribution of fat throughout the body is determined by the ratio: waist circumference (at the level of the navel) divided by the volume of the buttocks. The norm for men is 0.85; for women - 0.65 - 0.85.

Method 3. Taking into account age

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

Method 4. Brock's formula

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: 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? It is enough to measure the circumference of the thinnest place on the wrist with a centimeter.

Method 5. Nagler formula

There is a Nagler formula that allows you to calculate the ideal ratio of weight and height. For 152.4 cm of height there should be 45 kg of weight. For every inch (that is, 2.54 cm) over 152.4 cm, there should be another 900 g. Plus another 10% of the resulting weight.

Method 6. Formula John McCallum

One of the best formulas was created by expert methodologist John McCallum. Its formula is based on measuring the girth of the wrist.

The circumference of the wrist multiplied by 6.5 is equal to the circumference of the chest.
85% of the chest circumference is equal to the circumference of the hips.
To get the waist circumference, you need to take 70% of the chest circumference.
53% of the chest circumference is equal to the thigh circumference.
For the neck circumference, you need to take 37% of the chest circumference.
The circumference of the biceps is about 36% of the circumference of the chest.
The girth for the lower leg is slightly less than 34%.
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 proportionately folded if the waist circumference is 72 cm, the hips and chest circumference is about 97 cm, that is, if she wears 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.

Do you know how to calculate your ideal weight? Yes, you can use complex medical formulas and spend a lot of time. An online ideal weight calculator will do it in just 3 seconds! Enjoy!

You can calculate the ideal weight in kilograms, in each case, using special medical formulas. Why is this needed? Firstly, in order to properly monitor your own health, since extra pounds are not only an aesthetic, but also a medical problem. Secondly, to monitor the progress of weight loss or weight gain.

Using a free online calculator, you can determine the weight rate for a representative of any gender and age in a few seconds.

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 based on age, it is possible to determine the norm for a small child, a teenage girl, and a young man. 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.

You can calculate the body mass index using the formula BMI \u003d weight / height ^ 2, the calculation is simplified using the online BMI calculator. Body mass index is calculated as a ratio of height and weight, for men and women, these figures will be different. Depending on the BMI score, you can find out what recommendations to follow if you are overweight, and, conversely, if you are underweight.

Body mass index calculator

BMI table

The BMI calculator calculates correctly, only for adults (over 18).

Instructions for determining BMI

The BMI calculator has mandatory fields to fill in, where you should specify:

weight (in kilograms);
height (in centimeters);
press the button to calculate the indicators.

The resulting indicator (index) of the ratio of height and weight should be compared with the BMI table.

Underweight. The owners of underweight can become for several reasons - an innate constitution (thin physique), malnutrition (unbalanced diet), hormonal disorders, too fast metabolism, and hyperglycemia - the body's ability to absorb glucose at a high speed. Hormonal disorders should be corrected by an endocrinologist. The remaining violations require self-correction of dietary errors: increase the amount of carbohydrates and fats. Much more energy must be absorbed than such an organism spends, although this happens quite quickly. The use of simple carbohydrates is not prohibited. Loads should be directed at, aerobic training will only slow down the process of gaining body weight.
Normal weight. Happy owners of the norm should only follow in the same spirit. With a balanced diet and moderate exercise, body weight will be kept in place. When overeating, BMI can increase, so you should not increase calories so that later you do not resort to diets.
Overweight. Those whose index exceeded 25 should reconsider their lifestyle. First, review your diet. If the menu is dominated by carbohydrates (flour, sweet), you should reduce their consumption to a minimum. Eliminate sugary foods and increase your protein content in your diet. Second, analyze your physical activity. With a fixed lifestyle, fats are especially well absorbed, since the body does not spend energy, which means it accumulates subcutaneous fat. Start exercising, but take care of your joints, with excess weight, the joints are already subjected to stress.
Obesity. One of the causes of obesity is not only an excess of calories and an inactive lifestyle, but also hormonal disorders. Hormonal imbalances, such as an excess of female hormones and a lack of male hormones, can lead to the accumulation of excess fat, not to mention diseases such as diabetes. This problem can be solved only with the help of hormone therapy. If there are no violations, it is necessary to follow the measures, as in the recommendations for overweight. In any case, reduce the total caloric content of the diet, remove simple carbohydrates (sweets, and even fruits), walk more. And do not eat 3-4 hours before bedtime.
Severe obesity. In case of severe obesity, you should consult a doctor. Rather, this degree of obesity is provoked by more than just nutrition. It is necessary to take tests for hormones and identify the content of enzymes, the possible absence of which is unable to digest certain nutrients - fats and carbohydrates. Otherwise, proper nutrition and hiking will not interfere.

Underweight. In men, there are also a number of reasons for underweight - hormonal disorders, hyperglycemia, an accelerated metabolism and malnutrition. With high intensive loads and work associated with physical labor, an excess of calories in the diet should be ensured, exceeding the amount of carbohydrates over proteins and fats. You need to eat often, at least 6 times a day. Workouts should last no more than an hour.
Normal weight. With proper nutrition and physical activity, follow the usual way of life, without significantly changing anything in the diet and training.
Overweight. In men, a frequent case of overweight is not only an addiction to food, but also to drinks such as beer. The content of phytoestrogens in the composition of beer increases the production of female hormones, which leads to the accumulation of female-type fat (belly and thighs). In any case, there is the possibility of a hormonal imbalance, in the direction of increasing estrogens and reducing androgens. If the cause is a poor diet, eliminate high-glycemic foods from your diet and move more.
Obesity. In men, as in women, the cause of obesity can be endocrine disorders, as well as an excess of calories in the diet. Overeating can also be negatively affected by socio-psychological factors. Therefore, you should exclude all diseases and switch to a low-carbohydrate diet that is high in protein and fiber.
Severe obesity. It is urgent to consult a doctor endocrinologist or gastroenterologist. You can also take measures to prevent the possibility of gaining even more weight, which are recommended for overweight and obesity.

The calculation of the ideal weight is always problematic, since at the moment there are several ways to determine it. All of them, according to the assurances of the developers, are true, but women strive for the ideal, therefore, methods are used that give an average value. To calculate it, you can use online weight calculator which is presented below.

According to anthropologists, there are three types of figure in a person, which characterize the appearance and possible weight - asthenic, normosthenic, hypersthenic.

Asthenik is tall and light weight - these are standard people who eat a lot, but do not get better. The figure of the asthenic is angular, the bones "bulge", which somewhat loses its attractiveness.
Normostenik - average height and standard weight. Their health is the best, since such people are not prone to weight gain, the figure is harmonious and attractive.
Hypersthenic - growth is below average, and weight indicators are slightly higher than normal. The presented body has slight roundness, similar is observed in men and women. If a person with a hypersthenic body loses a lot of weight, his appearance will not be attractive.

From the above provisions it follows that it is important for a person to first study his body, and only then resort to. Perhaps losing weight will not be necessary at all, because it is important to pay attention not to the ratio of height and weight, but to the type of figure.

Mistakes will lead to forced debilitating diets, which women love to practice, striving for the ideal, but not being able to keep a low weight with their health characteristics.

How to determine the type of figure

In accordance with the above data, it is necessary to determine your body type, which will be important for both men and women.

To determine the following measurements are required:

Go to the mirror and draw your stomach in.
Next, you need to feel the lower ribs and evaluate their position relative to each other. This is called calculating the intercostal angle - the highest point of connection of the ribs in the middle of the human body.
If the angle is less than 90 degrees, then the figure of the anesthetic. If closer to a right angle, then this is a normosthenic. When the angle is more than 90 degrees, we are talking about hypersthenics - they have an expanded location of the bone, so they look plump even with normal indicators.

It is important for women to achieve the ideal weight, while it is clarified that it is not possible to determine it exactly. For each figure and person, the norm is determined individually, in most cases a person does not think about his condition, but looks precisely at his appearance.

About ideal weight

Calculating normal weight is not an entirely accurate procedure. Regardless of the results obtained, people tend to be thinner, men are slimmer and more prominent.

The ideal weight for a person corresponds to the following factors:

the existing weight and amount of fat in the human body is safe and does not provoke health problems;
the optimal indicator will not limit the movements of a person;
a woman or a man is satisfied with the appearance;
there is no comparison with other people.

In this case, it doesn’t matter what indicators a person has, but it is recommended to calculate the ideal weight for your height. In the presented way there is a certain ratio of appearance and health. Normal weight is recommended to be calculated and monitored (adhered to as much as possible) so as not to risk your health. The presented values are given to people to correct their diet and prevent the development of pathologies, mainly developing against the background of excess weight.

Expert opinion

Egorova Natalya Sergeevna
Nutritionist, Nizhny Novgorod

Yes, ideal weight is a relative and purely individual concept. When calculating it, many factors are taken into account: body mass index (BMI), constitutional type, amount of fat in the body, metabolic characteristics, etc. And yes, in hypersthenics, normal body weight is always higher than in asthenics.

Back in the days of the USSR, the formula for ideal weight was quite simple. 100 was subtracted from height, and the resulting number allegedly showed how many kilograms a person should weigh. Naturally, such calculations were inaccurate, brought little benefit and had practically nothing to do with reality. However, even today, many people measure the “normality” of weight by body mass index. I do not approve of this approach.

Moreover, I do not recommend determining the "ideal weight" on your own or with the help of friends and relatives. After all, you yourself will not be able to calculate the exact figure. And don't give yourself weight loss recommendations. So if you are planning to lose weight, contact a dietitian. This article does not list all the factors that a specialist takes into account when planning a weight loss program. In fact, there are many more. And be prepared for the fact that you may need to pass a series of tests.

How to determine the presence of excess fat in the body

There are several ways to determine the presence of excess fat. Its presence in the body provokes the development of cholesterol plaques, atherosclerosis and joint pathologies due to excessive pressure. In most cases, the legs suffer, but more serious problems can be encountered - osteochondrosis and spinal hernia.

Application of scales

The standard and common formula for calculating ideal indicators is to calculate the sum of 110 from your height. Calculating indicators is easy if you have a scale at home. Weigh yourself in the morning on an empty stomach and after going to the toilet.

Wrinkles on the abdomen

It is possible to determine a large amount of fat in the body, leading to obesity and a deterioration in the vital activity of the body, by the crease on the abdomen. For men, the norm is approved - 1-2 cm, for women - 2-4 cm. All indicators above 5 cm indicate the presence of obesity. This method will not make it possible to calculate how many kilograms you need to lose to an ideal figure, but may indicate the presence of health problems.

Body mass index

There is a way to calculate the norm by body mass index. To do this, use the formula: weight / height in meters2.

Here is the following definition:

if the body mass index is less than 18.5, then the person has a deficiency;
up to 24 - the norm;
up to 29 - excess;
over 30 indicates obesity.

The resulting value must be compared with the indicators in the table.

Using a calculator

For ease of calculation, an ideal weight calculator for height and age is offered.

Scales with the calculation of the amount of fat

Body mass index indicators give only mathematical values. It is noteworthy that the existing scatter entails significant differences in the amount of fat in the human body and in appearance. You can simplify your work and use only scales endowed with the function of calculating the amount of fat in a person. To do this, a weak electrical impulse is passed through the body, which easily passes through water and muscles. Difficulty passing through fat and leads to the calculation of indicators.

How to determine real indicators

Often, men and women begin to lose weight with large indicators, hoping to achieve significant results.

In order not to overestimate your capabilities, it is recommended to use the following formula to calculate the possible achievement:

45 kg + 1 kg for each cm of growth, which is over 150 cm + 0.5 kg for each year over 25 years, but not more than 7 kg.
Next, you need to add 4-7 kg to the value obtained.
Add another 4-7 kg if he currently weighs 90 kg.
If at the moment the person weighs more than 100 kg, add a few more kilograms.

As an example, you can take a woman weighing 82 kg, 165 cm tall and 31 years old. For her, normal indicators will be calculated as: 45 + 15 + 3 + 7 \u003d 70 kg. The value can be reduced to 67 - the amount will be obtained if you add 4 kg.

It turns out that a woman should weigh from 67 to 70 kg. Otherwise, she will not be able to maintain the achieved weight (for example, when losing weight up to 55 kg), and health problems will also arise.

Important! When losing weight or calculating indicators, it is recommended that you pay attention not to your own ambitions, but to the need to improve your health.

Weight and health are closely related, which should be monitored at all times. You need to weigh yourself constantly - every 2 days or once a week, while controlling your diet. To maintain the achieved ideal forms, it will be enough to spend weekly fasting days. They will help get rid of excess fluid in the body, which contributes to the breakdown of fat cells.
