How to find out and calculate your weight. Calculation of weight by height and age. Ideal Weight Calculation

To "blind" the ideal figure, it will take a significant amount of time and effort. However, before embarking on this difficult task, go to the mirror and look at yourself critically, but with love. You can take a centimeter and measure all your circumferences, just don't draw any gloomy conclusions if you don't get 90-60-90.

Most likely, it really will not work out, but there is no tragedy in this. First, there are many things that can be fixed. Secondly, a lot of things may not need to be corrected.

Type of constitution

For example, anthropologists distinguish three main types of constitution (not to mention numerous transitional and intermediate variants). These three types are called: normosthenic, hypersthenic and asthenic.

A person with a hypersthenic constitution, most often of average or below average height, broad-boned, with relatively short arms and legs and a wide chest. Asthenik is tall, long-legged, with a narrow chest, as if directed upwards. Normostenik means “normal”: growth is average and everything else too.

You can quite accurately determine your constitutional type by the so-called intercostal angle, which is formed by the lowest costal arches. Stand in front of a mirror with your stomach in and your chest out, and see what your intercostal angle is (you can even take a large protractor and measure).

If it is approximately 90 degrees, then you are normosthenic. If this angle is sharp, less than 90 - you are asthenic, and if obtuse - hypersthenic. In the latter case, in particular, successful weight loss can lead to a not very successful result: thinness will not adorn the hypersthenic, and some “extra” weight, on the contrary, will round out the somewhat square outlines of the figure.

Ideal weight is not a number on the scale, but an integral important component of your life.

Ideal weight

Your weight is ideal if:

• It does not cause health problems (or potential risks);
• It does not restrict you in your daily life, desires and needs;
• You are satisfied with your body as it is, and at the same time you do not feel embarrassed;
• You like your body and don't compare yourself to the people around you (or actors, singers, athletes, etc.).

There are various indicators and formulas that can determine the approximate weight range in which you may begin to develop health problems, as well as the weight you need to strive for in order to minimize or completely eliminate these problems.

Methods for determining excess weight

1. Determination of excess weight using scales

The simplest (and most approximate): height (in centimeters) minus 110. The resulting number (in kilograms) is the ideal weight. However, this does not mean that “everything else” is superfluous.

There is the easiest and most accurate way to determine if you are overweight: just measure the crease on your stomach. For women, the allowable norm is 2-4 cm, but for men it is slightly less - 1 - 2 cm. Experts say that from 5 cm or more is obesity. True, unfortunately, in this case we will not see the exact result of how much we need to lose. This is just a kind of hint that it's time to sit down at the simulators and on a diet.

3. BMI - body mass index (Body Mass Index)

The so-called body mass index (BMI) has received general recognition. His calculation: Divide your weight in kilograms by your height in meters squared. Example: BMI \u003d 68kg: (1.72m x 1.72m) \u003d 23. This formula is good because it works for both “kids” and “giants”.

The following BMI values ​​are distinguished:

less than 15- acute weight loss;
from 15 to 18.5- weight deficit;
from 18.5 to 24 - normal weight;
from 25 to 29- overweight;
from 30 - 40- obesity;
over 40- severe obesity.

5. Scales that determine the percentage of body fat

But BMI does not speak about the distribution of kilograms on the body. Physique matters. With the same height and weight, one person will be slim and strong, the other full and loose. The ratio of muscle and fat is important, how many percent of the total body weight is fat mass, how much is muscle and bone, how much is water. The normal proportion of fat in the body of men is 12-18%, women - 18-25%.

Recently, devices have appeared to determine the percentage of body fat. In the process of bioelectrical analysis, a weak, absolutely safe electric current is passed through the body. The principle of analysis is based on the fact that an electrical impulse passes more easily through muscles and water than through fat. Now scales have appeared that include this technology, you can use them to regularly and more or less accurately measure at home not only your weight, but also the percentage of fat.

6. The formula for determining the realistically achievable weight

The formula is applicable for cases when a person begins to lose weight with a fairly large weight.

The calculation is carried out in two stages:

1. First determine your weight, as if you were the owner of a normal metabolism:

(45 kg) + (1 kg for each centimeter of height over 150 cm) + (0.5 kg for each year over the age of 25, but not more than 7 kg).

2. Then carry out a correction for a slow exchange:

Add from 4.5 to 7 kg;

Add another 4 to 7 kg (with an initial weight of about 90 kg);

A few more kilograms are added (with the initial weight, greatly exceeding 100 kg).

An example for a fifty-year-old lady with a height of 158 cm, weighing 90 kg today:

45 kg + 1 kg (158 cm - 150 cm) + 7 kg + 7 kg + 7 kg = 74 kg.

If our lady manages to bring herself up to 60 kg, then she is provided with all sorts of health troubles and an inevitable quick return to her original weight, plus a certain number of cheerful kilograms.

How does body weight affect health?

What does the number on the scale really mean? How does it relate to all the reasons why you want to lose weight? Perhaps you want to look more attractive, improve your health, fit into your favorite jeans or put on a beautiful dress that has been hanging in your closet for many years, improve your physical shape, return to your youth, or are you just more comfortable living with fewer kilograms? The number on the scale is not what determines your success or failure. There are so many ways to measure progress and success besides constantly monitoring the scale.

There is only one reason to talk about "normal" or "ideal" weight and that reason is your health.

Which can later lead to serious illness or even death. Although your specific weight may not be the cause of any diseases, it is absolutely known that people whose weight is above or below the “normal” are much more susceptible to various health problems.

Before starting any diet or exercise cycle for weight loss, you should first decide what weight you would like to achieve as a result. That is, to set an end goal to strive for. This goal is often ideal weight. This is either the weight in which you are physically comfortable, or an index that satisfies you in terms of external parameters.

It is important not to go too far in setting a goal, because if you set a goal that is too high, you may never achieve it. If you have to lose more than 5 kg of weight, it is better to break the goal into several stages. For example, lose 1.5 kg every month for six months, etc. Don't forget to read.

How can you help yourself decide what your ideal weight is? Indeed, unfortunately, not everyone can have a wasp waist due to their constitution from birth, but you can look good with any figure if the weight is normal.

To mathematically determine your ideal weight, you need to calculate several parameters. There are many ways to do this. Below are the main ones.

Calculation of the norm of weight according to the Body Mass Index (BMI)

It is calculated by the formula: weight (in kg) divided by height (in m) squared. For example, if the weight is 64 kg with a height of 167 cm, then the IMS will be calculated as follows: 64 / 1.67 2 \u003d 22.9. From the table below, you can determine if your index is normal:

In our case, the IMS is normal, since the result of 22.9 falls in the range of 18.5 - 25. However, this weight may still not satisfy its owner. Accordingly, you can calculate your ideal weight using the minimum rate of IMC. Let's do it: 19.5 x 1.67 2 = 54 kg.

Broca's index

It is used if your height is in the range of 155-170 cm. Calculation formula: Height (in cm) minus 100 and minus 10. It turns out: (167 - 100) - 10 \u003d 57 kg

Breitman index

Calculation formula: Height (in cm) multiplied by 0.7 and minus 50 kg. We get 167 x 0.7 - 50 \u003d 66.9 kg

Borngardt index

To calculate your ideal weight, you need to apply the formula: Height (cm) multiplied by the chest circumference (cm) and divide the result by 240. In our version (given that the chest is 92 cm) it will turn out: 167 x 92 / 240 = 64 kg

Noorden index

To understand your normal weight, you need: Height (in cm) multiplied by 420 and divided by 1000. We get: 167 x 420 / 1000 = 70 kg

Tatonya index

Normal body weight is calculated by the formula: Height (in cm) minus (100 + (height minus 100) divided by 20). A little confusing, let's look at an example: 167 - (100 + (167 - 100) / 20) = 63.7 kg

All those who lose weight are interested in the question of the norm. What weight is considered normal for yourself? There are a number of formulas, using which you can determine to what extent your body weight corresponds to one or another average value. After all, all these formulas are derived from the calculation of the average person. Therefore, resorting to them, one must clearly realize that any formula for normal weight is conditional.

In reality, each of us has our own individual genetically predetermined value of the optimal body weight, which depends on the totality of innate structural features of the tissues and organs of the body as a whole.

So, for example, there are three body types - asthenic (thin-boned / ectomorph), normosthenic (normal / mesomorph) and hypersthenic (big-boned / endomorph).

To determine your type, you need to measure the circumference of your wrist.

• Less than 16 cm - asthenic;
• 16-18.5 cm - normosthenic;
• More than 18.5 cm - hypersthenic.

• Less than 17 cm - asthenic;
• 17-20 cm - normosthenic;
• More than 20 cm - hypersthenic.

In addition to body types, the body of each of us is programmed for a certain weight. This program is included by the mother during pregnancy. It is believed that if she gained excess weight during pregnancy, then the child may have difficulty in controlling body weight in the future. In the course of our lives, both wrong and we are laying another program. During weight loss, many are faced with the so-called balance point or set point, when using healthy methods, and if it works out, then they can’t keep it.

For example, you weighed 90 kg, lost weight to 55 kg, want to lose another 5 kg, but it doesn’t work out no matter what you do. At the same time, even arranging a rest from the diet and small holidays, you do not gain more than 3-5 kg, which you then easily lose. Perhaps you have reached your point of balance, and overcoming it can cost you dearly. When the body is under constant stress, and diets, training and high demands on oneself are constant stress, the risk increases. It is important to listen to yourself and the needs of your body.

If we do not take into account the individuality of the body and physique, then we can use the following simple formulas in approximate calculations (author P.P. Broca, 1871):

For men

(Height in cm - 100) x 0.9 = ideal weight.

For women

(Height in cm - 100) x 0.85 = ideal weight.

There is another formula that can be used for both men and women:

(height in cm - 100) = ideal weight.

Example: If your height is 152 cm, your weight should be 152 - 100 = 52 kg.

There is another formula:

Height in cm x Bust in cm / 240 = ideal weight.

Example: (155 x 96) / 240 = 62 kg.

Do not forget that it is necessary, nevertheless, to take into account the physique, that women naturally have more fat than men.

Therefore, you can use the following data to determine your ideal weight:

For men

For women

Ideal weight formulas help you figure out how much weight you can lose. However, it is important to understand that two people with exactly the same weight can look completely different. It's not about height or body type, it's about body composition - the ratio of muscle to fat. Look at the photo.

Adipose tissue is more voluminous than muscle tissue. Therefore, the girl on the left looks more curvaceous than the girl on the right, although they have the same weight. And that is why it is so important to strive not so much to lose weight as to strengthen muscles with the help of strength training and.

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.

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.

1. 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.
2. 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.
3. 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 stationary 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.
4. 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.
5. 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.

1. 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.
2. Normal weight. With proper nutrition and physical activity, follow the usual way of life, without significantly changing anything in the diet and training.
3. 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.
4. 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.
5. 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.
