How to calculate the correct weight. How to calculate excess 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 an average value obtained on the basis of a set of given physiological parameters of a person, such as height, age, gender, and body type. But the state of health, the level of 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 a 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).

An important point: the calculation of the 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.

What a beautiful body women have in their youth! If you pay attention to your figure constantly from a young age, then even childbirth will not spoil it. But if you don’t follow her, plus age, then problems begin. And how you want to have a beautiful figure in any period of time. How to calculate your ideal weight? This will be discussed.

Body shaping

With age, people begin to move much less and eat more, and food is consumed more fatty, high-calorie. And the figure grows in breadth, by leaps and bounds, problems begin: shortness of breath, pressure, varicose veins. But now you have decided that it is time for you to change your lifestyle and bring the figure into proper shape. Maybe diets or fitness classes will help, they say jogging and swimming help. This is where the question arises of how to calculate your ideal weight.

Before you start any business, you need to know what result will suit you in the end. How many kilos do you need to lose, or, on the contrary, gain. For this, you should make a calculation and find out which indicator will be optimal for you. How to calculate your ideal weight?

Ideal weight according to different methods

There are many methods. Here is some of them:

• Brock's method: subtract 110 from the height in centimeters, the result is almost perfect weight, that is, if a woman has a height of 180 cm, then, subtracting the prescribed 110, we get 70 kg. The method is controversial, since in this case the age of the woman is ignored.
• Measure the fat fold using a special ruler - a caliper (you can use a caliper). In women, the norm is from 2 to 4 cm, in men - from 1 to 2 cm.
• American method: subtract 150 from the height, increase by 0.75, add 50. If the lady is 170 cm tall, then as a result she should weigh 65 kilograms.
• Lorentz method (simplified version): divide the height by two and subtract 25, that is, we divide the same 170 centimeters in half, we get 85 and subtract 25, in the toga we have 60.
• Bongada method: multiply the height by the volume of the chest, divide by 240. So, we multiply 170 by the standard 90, divide by 240 and get 63 kilograms 75 grams.
• Ketele method: divide the weight of a woman by the size of her height squared, that is, if a woman has a weight of 80 kilograms and the same height of 170 cm, then 80 kg should be divided by 2.89 (1.7x1.7). We get an excess body weight of 27 kilograms per square meter.

To date, it is the method of Adolf Ketele, a Belgian sociologist, that is practiced by many specialists, it can be used by ladies of all ages.

How to calculate weight online

The Solovyov index made it possible to determine three types of human complexion:

• if thin bone - asthenic;
• if normal bone - normosthenic;
• if a wide bone - hypersthenic.

Using this method, you can determine which bone a person has, you only need to measure the narrowest place on the wrist.

You can still use this method, although it is close to the method above. Grasp the left hand in the wrist area with two fingers, index and thumb. And then the same way:

• embraced with ease - asthenic;
• fingers lay back to back - normosthenic;
• not embraced - hypersthenic.

How to calculate ideal weight online? In order to calculate the average mathematical value of the required weight of a person, you will need to use a special calculator. You should enter your data, and the table will give the result.

We find out the result

• Gender Female;
• age, say, 35 years;
• woman's height - 170 cm;
• wrist girth - 16 cm.

The normal weight of a woman according to the indicated data is 70 kg.

Find out what should be the weight, taking into account age

It has long been known that metabolism - a chemical reaction that occurs in a living organism to support life, is different in youth and in adulthood, and it is she who plays an important role in the weight category of a woman. But now let's talk about the structure of the human body to calculate the perfect weight. Let's go back to body types.

Women who have thin bones are rarely overweight, as they are usually energetic and mobile, so that even eating excess food does not harm them. They manage to spend their energy faster than it has time to accumulate.

Women who have a normal type of bones are usually built in proportion to all sizes of the human body. The weight of such women is usually normal, the figures are beautiful.

Women who have a wide bone, usually, even without being overweight, look heavier, since both the chest and the circumference of the hips are wide. Yes, it's easy for them to put on weight.

How to calculate the ideal weight based on age? No matter how a woman looks, she has a latent (latent) fullness, which indicates the percentage of fat, muscle and bones. Therefore, for mature ladies there is a formula developed by Brock. According to her:

• when the height is up to 165 cm, then the coefficient 100 is taken away;
• if the height of a woman is from 166 to 175 cm, then the coefficient 105 is subtracted;
• if the height is more than 176 cm, then the coefficient 110 is minus.

Professionals define Brock's indicator as reliable for ladies from 40 to 50 years of age, and after 50 years it should be increased by 5-7% of the indicated indicators.

How else to calculate the optimal performance?

How to calculate the ideal weight of a woman? What are ideal settings? Sane women understand that the ideal weight and parameters 90x60x90 are completely different things. Only a girl of eighteen or twenty years old can have such weight and such parameters, and women of more mature age are more likely to be skeptical about such sizes.

Weight, close to the ideal of an adult woman, is the size at which she feels great when she herself admires her figure. When, climbing the stairs, she does not suffocate, when, when she is about to go swimming in the lake, she has not been on a diet for a week. The ideal parameters are when you are comfortable, both yourself and people like you.

A factor of 100 is subtracted from the height of a woman;

A coefficient of 150 is subtracted from the height of a woman, and the result is divided by two;

Calculate Ideal Weight: Calculator

If you want to be healthy - a weight calculator will help you with this. He will calculate both the ideal body weight and the allowable kilograms that will not interfere with your life. It will also help determine your body mass index - a value by which you can evaluate the coincidence of body weight with height.

How to calculate the ideal weight online for women using a special calculator? First you need to upload data for calculation according to the formula, where the weight is calculated in kilograms, and her height is calculated in meters squared. For example, a woman who weighs 70 kg and is 180 cm tall would have a body mass index of 70: (1.8 x 1.8) equal to 21.60, which means that she has a completely normal weight. Since it is considered that if the index:

• less than 15 is almost anorexia;
• if the index is from 15 to 20, then it is considered that this is a lack of weight;
• if from 20 to 25 - perfect weight;
• from 25 to 30 - overweight;
• and from 30 - obesity.

Convenient home scales

Calculating the ideal weight, it turns out, is not difficult at all. The body mass index may indicate the total mass, but it will not show the distribution of all kilograms. Since two people can have the same weight and the same parameters, but be completely different build. Again, the percentage of total body weight, that is, muscle, fat, water, and bone, plays a role here. In women, this range is from 18 to 25%.

You can also calculate your ideal weight using a scale. Modern technology has advanced far, and scales have appeared on sale that help determine what percentage of body fat is in the body. They are very convenient to use at home.

In general, if you are a little overweight, but at the same time you feel great, calm down, you should not lose weight just because someone thinks that it should be so. And you won't have to struggle with the question of how to calculate your ideal weight.

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. This is not surprising. 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 figure. You should pay attention to sports or at least increase physical activity in order to put your 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.

Knowing if your weight is within normal body weight helps you understand your body, identify problems, and sometimes even make a diagnosis right away. Weight control is considered the most important preventive measure for a number of dangerous diseases.

Unfortunately, often body weight worries not those people who should be worried (obese patients), but young girls who have driven into their heads that they do not meet the TV-magazine standards 90-60-90, and bring themselves to fainting with all sorts of diets . In the case of a serious illness, such as diabetes, starvation and semi-starvation diets pose a threat to life.

Therefore, let's determine together the compliance of your weight with the norm. Take a notepad and a pen in your hands, and even better, a calculator, we will count. The procedure for calculating the normal weight is quite simple and does not take much time.

Many formulas are used to determine normal body weight. The simplest and most famous

M \u003d P - 100, where M is the mass in kg; P - height in cm.

But this formula in this form is very inaccurate and is applicable only for a very approximate calculation.

It is advisable to use the full formula (see table below).

Calculation of ideal body weight

You can also use the modified formula: ideal body weight \u003d (height in cm minus 100) and another minus 10% for men; BMI \u003d (height in cm minus 100) and another minus 15% for women:

• 1 degree of obesity - the actual body weight exceeds the ideal by less than 30%;
• 2 degree of obesity - if the actual weight exceeds the ideal by 31-50%;
• 3 degree of obesity - if the actual weight exceeds the ideal by 51-99%;
• 4 degree of obesity - if the actual weight exceeds the ideal by as much as 100% or more.

Currently, in most countries of the world, body mass index (BMI), or the Quetelet index, is used to determine normal and overweight in a person:

BMI \u003d M / R 2, where M is the mass in kg; R 2 - height in meters, squared.

According to the international classification, an indicator from 18.5 to 24.9 kg / m 2 is considered the norm. A reading below 18.5 indicates underweight. If the BMI is in the range of 25 to 29.9, it is overweight, and obesity is diagnosed with a BMI over 30.

For example, your height is 181 cm, weight is 99 kg. Let's do a simple calculation: 1.81 2 = 3.2761. Divide 99 by 3.2761 for a BMI of 30.22, which means you are one of the many with weight problems:

• 1 degree of obesity (mild obesity) - with a BMI between 27 and 35;
• 2 (moderate) - with a range of values ​​35-39.9;
• 3 (severe or painful) - with a BMI of 40 or more.

Table of normal human body weight by age

For the diagnosis of obesity, in addition to the total mass, the volume of the waist and hips is important. So, for men, a waist circumference of 94 cm is considered acceptable, for women - up to 88 cm. With a waist circumference of 94-101 cm in men and 102 cm or more in women, the risk of metabolic complications is high.

If your waist circumference exceeds the indicated figures, you have an abdominal (visceral) type of obesity, that is, fat is deposited around the internal organs - the liver, pancreas, heart, disrupting their work. It is this type of obesity that is a risk factor for the development of diabetes mellitus, coronary heart disease, arterial hypertension, myocardial infarction!

Patients with type 1 diabetes mellitus, whose body weight is normal, naturally do not need to worry about the impact of obesity on diabetes.

Patients with type 2 diabetes who have a normal weight (there are very few of them) should try to keep it close to ideal numbers, so be sure to strive for ideal weight for your age.

Well, for people with diabetes mellitus types 1 and 2, who are overweight or obese, the basics of calculating the calorie content of the diet must be remembered and applied daily, this is the most important thing for you in the treatment of diabetes.

Counting calories is also important for people with a lack of weight, they already know that gaining weight is by no means an easy task. And correctly calculated nutrition with the determination of the need for kilocalories will allow you to gain the missing kilograms.

The phrase "ideal weight" gives rise to the most controversial associations. Someone imagines a fashion model with proportions of 90-60-90. Someone, on the contrary, a magnificent Kustodievskaya lady. And someone is watching the fluctuations in the indicators of weights, reminiscent of a cardiogram, and has little idea of ​​​​what to stop on. It seems that your favorite jeans fit, and nothing hangs over their belt.

But where is the ideal?

In order to make life easier for those who are trying to maintain this very “ideal weight” and their doctors, back in the century before last, the Belgian sociologist and statistician Adolf Kyutle developed a simple formula for calculating the so-called body mass index. It is still actively used in medicine and sports today. Looks like that:

As a result of calculations, a two-digit number with digits after the decimal point is obtained. According to the latest recommendations of the World Health Organization, it is interpreted as follows:

Yunna Popova, Head of the Metabolism Department at the Nutritional Clinic of the Russian Academy of Medical Sciences, says that all formulas for determining the ideal weight, despite the prevalence of their use, do not take into account the so-called body composition. That is, the percentage of weight of fat, muscle and bone tissue.

According to Popova, an increase, for example, in BMI, is often observed in professional athletes who have impressive muscle mass. In particular, weightlifters. For them, this index can show a third or more degree of obesity, although the actual amount of fat in such people is negligible.

“When calculating according to the formula, an athlete finds himself 30 kilograms of excess weight, but in fact, you need to lose weight by no more than five,” says Popova. Also, an increase in BMI is possible with diseases that cause water to linger in body tissues.

Therefore, the expert says, in addition to BMI, specialists use methods that determine body composition. For example, with the help of caliperometry - determining the thickness of the fat fold. Or bioimpedancemetry - hardware determination of the amount of fat, water and muscles in the body of a particular person. These studies are simple and painless, but only a qualified specialist can perform them.

Therefore, Popova believes, before being frightened by the results obtained after home calculations and going on strict and unbalanced diets, you must first visit a doctor who will tell you exactly what shortcomings it makes sense to deal with.
