The formula for calculating BMI according to Kegle: Body weight (kg) divided by Height (m) squared.
For example: a young woman at the age of 25 with a weight of 50 kg and a height of 1.62 m calculates an index of 50 / (1.62 * 1.62) \u003d 19.05 - a normal body mass index, but close to underestimation (less than 19 - deficiency weight). 
If you have problems with ideal mass bodies: problems with overeating, anorexia nervosa or bulimia, or you do not know how to convince yourself to become slim and healthy -
How to calculate BIM? Everyone needs to control their weight, both women and men. There is a formula that will help determine the body mass index for men. Extra pounds adversely affect not only the appearance, but also health.
The internal organs are also covered with fat and it becomes difficult for them to function. Shortness of breath appears, the work of the heart, pancreas is disturbed, diabetes mellitus and a number of other serious diseases develop. Therefore, it is very important to monitor the norm of weight.
Calculating BMI: why you need to do it
A calculator that calculates your weight-for-height norm was developed in 1869 by the Belgian mathematician Adolphe Quetelet. He made it easy for people who cared about their proportions and appearance.
Only this method(calculator) does not always have accurate data, but considers indicative. Since not only height and weight are involved in the calculation, but also the type of constitution, heavy or light bone, muscle mass, age.
The calculator that is available on the Internet is approximate and you need to focus on it approximately. For example, if a man or woman is an athlete, then it will be difficult for them to calculate their BMI, because muscle mass is heavier than fat.
The formulas that are presented on different websites of countries and WHO vary significantly in the final data. From a medical point of view, WHO takes the average, which can be in real life redundant for humans.
How to Calculate Body Mass Index
The formula that will help you find out the normal weight, taking into account height, is calculated as follows:
BMI for men = Weight (kg) / Height (m) 2
This easy formula will help you always stay slim and beautiful. You can also substitute your data into the online calculator and get an instant result.
Let's use an example to show how it is calculated:
Gender: Male.
Age: 35 years old.
Height: 175 cm 2 = 1.75 * 1.75 = 3.06.
Weight: 70 kg.
We substitute in the formula BMI \u003d 70 kg / 3.06 \u003d 22.88
BMI calculator
Thus, according to the table that we present below, the indicator is within the normal range, taking into account age and gender. Having memorized an easy formula, you can always calculate your indicators and control your weight without an online calculator.
BMI norm in men: the meaning of indicators
After calculating your BMI, you can see in the table whether your weight is within the normal range, taking into account age.

| 18-30 years old | Over 42.5 | Obesity 4 degree |
| 30 years and older | Over 43 | Obesity 4 degree |
Each person always has something to strive for, and there is no limit in the ideal. Everyone has their own idea of the beauty of the body, someone likes thin ones, and someone loves a small tummy from their man.
How to deal with extra pounds
Ways to deal with extra pounds enough. They can be divided into 3 groups:
- Non-medical getting rid of kg;
- Medical treatment of overweight;
- Surgery.
At the same time, the last item has a number of contraindications that may prohibit doing, for example, gastric bypass due to the presence of too large a BMI and there is a risk of death. Therefore, before such complex and serious operations, a corrective diet is prescribed.
Non-medical relief excess weight recommended when:
- There is a risk of complications with excess body weight;
- Waist >101-102 cm;
- Obesity of any painful stage.
We can conclude: any treatment of obesity begins with the 1st point - not drug therapy.
Medical therapy for obesity:
- There was no effect without the use of drugs;
- BMI of a man over 34 kg / m 2;
- Waist circumference is 103 cm.
Surgical care in the treatment of obesity has contraindications:
- Alcoholism;
- Mental disorders.
Indications for surgery:
- Lack of effectiveness in the second method of therapy (medication);
- When, with obesity over 30 kg / m 2, it has a risk of death in the presence of such diseases:
- Diabetes mellitus type 2;
- Hypertonic disease;
- IHD (ischemic heart disease);
- sleep apnea syndrome;
- Violation in the circulatory system.
- Obesity of any degree exceeds 4-5 years.
Non drug therapy
It is based on diet therapy, which consists in a phased reduction in kilograms, combined with physical activity and psychological training.
- Gradual weight loss within 5-6 months by 10-15% of body weight;
- Retention of the achieved result;
- Continuation of weight correction.
To achieve results at stage 1, a man needs to consume no more than 1800 kcal per day with moderate physical activity. To achieve a sharp decrease in body weight, the amount consumed per day should not exceed 1000 kcal.
But mono diet have a number of contraindications:
- Age restrictions - 60 years or more;
- The presence of chronic diseases: cirrhosis of the liver, renal failure, stones in the gallbladder;
- Diabetes mellitus type 1;
- Asthma bronchial (heavy breathing);
- Diseases of the endocrine system, thyroid gland;
- Oncological diseases;
- Pathology of the heart muscle;
- Alcoholism.
Supportive drugs for maintaining weight are prescribed by a doctor:
- "Sibutramine" Sibutramine;
- Fluoxetine Fluoxetine is an antidepressant.
Therapy of obesity with drugs
Drugs are prescribed by a doctor, do not use them without a prescription. All of them dull hunger well, but have many contraindications and side effects to consider before taking.
To "blind" perfect figure would require 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 out chest, 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- this is not a number on the scales, 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 Everyday 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, what percentage of total weight body is the mass of fat, how much - muscles and bones, how much - 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 substance is passed through the body. electricity. The principle of analysis is based on the fact that electrical impulse passes more easily through muscle 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 the closet for many years, improve your physical form, return to youth, or is it just more comfortable for you to live 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.
Many ways, formulas for determining normal weight some of them are described on this page. Remember - if your weight differs from the "ideal weight" calculated by these formulas by 5-10% in one direction or another, this is most likely normal and is due to the individual characteristics of the body. If you feel good, move easily, you do not catch your breath and your muscles do not hurt after climbing the stairs to the third or fourth floor - everything is in order.
The simplest (and very accurate) way to diagnose obesity is to measure the thickness of the skin fold on the abdomen. The norm for men is up to 1-2 cm, for women - up to 2-4 cm. A wrinkle of 5-10 cm or more - obesity is obvious.
The well-known formula: ideal weight is equal to height in centimeters minus one hundred. But this formula is too inaccurate, gives an acceptable result only for people of average height, does not take into account the physique and pumped up muscles.
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 "gullivers". A BMI of 19 to 25 is considered the norm. A BMI less than 19 is underweight, 25-30 is overweight, 30-40 is obese, more than 40 is severely obese.
