How to calculate body weight. How to calculate excess weight

The results of BMI calculations are not suitable for assessing the weight of professional athletes, pregnant women, as well as people suffering from edema and other disorders that lead to an incorrect assessment of the original data.

Weight ranges in this calculator are calculated taking into account height, according to the methodology of the World Health Organization (WHO).

The very method of estimating weight by BMI is intended for primary detection underweight or overweight. Obtaining an estimate different from the norm is the reason for contacting a nutritionist and endocrinologist in order to conduct an individual weight assessment and make recommendations for its correction, if necessary.

Range ideal weight(norm) shows at what weight the probability of occurrence and recurrence of diseases associated with overweight or underweight is minimal. In addition, as practice shows, a person with normal weight looks not only healthy, but also the most attractive. If you adjust your weight, it is highly recommended not to go beyond the norm, in order to avoid health problems.

About weight categories

underweight usually an indication for increased nutrition; consultation with a dietitian or endocrinologist is also recommended. This category includes people who are malnourished or have a disease that leads to weight loss.
Underweight is also typical of professional models, gymnasts, ballerinas or girls who are overly fond of weight loss without the control of a nutritionist. Unfortunately, this can sometimes lead to health problems. Therefore, weight correction in this range should be accompanied by regular medical supervision.

Norm shows the weight at which a person has the maximum chance of staying healthy as long as possible, and, as a result, beautiful. Normal weight is not a guarantee of good health, but it significantly reduces the risk of disorders and diseases caused by overweight or underweight. In addition, the owners of normal weight, as a rule, are in good health even after intensive physical activity.

Preobesity speaks of being overweight. A person in this category often has some signs associated with excess weight (shortness of breath, increased blood pressure, fatigue, fat folds, dissatisfaction with the figure) and has every chance of moving into the category of obesity. In this case, a slight weight correction to the norm, or to values ​​close to it, is recommended. It also does not hurt to consult a nutritionist.

Obesity- an indicator of chronic disease associated with excess body weight. Obesity invariably leads to problems with cardiovascular system and significantly increases the risk of acquiring other diseases (diabetes, hypertension, etc.). Obesity treatment is carried out exclusively under the supervision of a nutritionist or endocrinologist, and only after necessary analyzes and definitions of its type. It is not recommended to engage in uncontrolled diets and serious physical exertion for obesity, as this can provoke additional problems.

Answers on questions

What is the ideal weight for me?

The calculator calculates a weight range that is ideal for you based on your height. From this range, you are free to choose any specific weight, depending on your preferences, beliefs and requirements for the figure. For example, adherents of a model figure tend to keep their weight on the lower border.

If your priority is health and life expectancy, then the ideal weight is calculated based on medical statistics. In this case, the optimal weight is calculated based on a BMI of 23.

Can you trust the resulting estimate?

Yes. Adult weight estimates are based on the results of authoritative research by the World Health Organization (WHO). Weight assessment from birth to 18 years of age is carried out according to a separate special method, also developed by WHO.

Why is gender not taken into account?

The BMI of adults is assessed in the same way for both men and women - this is justified by the results of statistical studies. At the same time, for weight assessment, gender and age are of fundamental importance.

Some other weight calculator gives a different result. What to believe?

There are a huge number of calculators designed to give an estimate of weight based on height and gender. But their formulas, as a rule, were developed in the last century by individuals or groups based on criteria that are unknown to you or do not suit you (for example, formulas for evaluating athletes).

The WHO recommendations used in this calculator are based on common modern people, subject to conditions modern life, advances in medicine and based on recent observations of the population of all continents of the planet. Therefore, we trust only this technique.

I think the result should be different.

Evaluation is based solely on the height and weight you provide (and age and gender for children). In case of unexpected results, please double-check all entered data. Also, make sure that you do not belong to any of those whose weight cannot be assessed through the body mass index.

My result is underweight, but I want to lose more weight

There is nothing unusual in this, many professional models, dancers, ballerinas do just that. However, in this case, it is recommended to lose weight only under the supervision of a nutritionist and endocrinologist, so as not to harm your health. if it means something to you.

My result is normal, but I consider myself fat (or thin)

If you have concerns about your figure, then we recommend that you go in for fitness, having previously consulted a good nutritionist.

Please note that some elements of the figure are almost impossible to correct only with the help of fitness, exercise, diet, or a combination of both. Your goals should be analyzed by an experienced doctor in order to assess their reality, consequences and prescribe only the right procedures.

My result is pre-obesity (or obesity), but I do not agree with this

If you are an athlete with a high muscle mass, then the BMI weight estimate is simply not intended for you (this is mentioned in). In any case, for an accurate individual weight assessment, contact a nutritionist - only in this case you will receive an authoritative result with a doctor's seal.

Why am I considered too thin or fat even though my weight is normal?

Pay attention to the personality and weight of those people who bother you. As a rule, they judge exclusively by themselves: subjectively. Fat people always consider thin people to be skinny, and thin people consider fat people to be fat, moreover, both of them can have weight within healthy norm. Take into account and social factors: try to exclude or stop those judgments in your address that are based on ignorance, envy or personal hostility. Only an objective assessment of BMI is worthy of trust, which clearly indicates the norm, excess or deficiency of mass; and trust your anxieties about the figure only to supportive people of your weight category or a doctor.

How to calculate body mass index (BMI)?

It is necessary to divide the weight indicated in kilograms by the square of the height indicated in meters. For example, with a height of 178 cm and a weight of 69 kg, the calculation will be as follows:
BMI = 69 / (1.78 * 1.78) = 21.78

How much should you weigh?

❧ The most important indicator of human health — normal weight and its stability maintained for a long time.

If your lifestyle is correct and healthy, then your weight will be close to ideal and will easily be maintained within the normal range.

An unhealthy lifestyle leads to changes in body weight (more often weight increases), after which various diseases begin.

Body weight (weight) is an integral assessment of the degree of metabolism, energy and information processes in the human body.

❧ Weight regulation is the regulation of all processes in the body.

To estimate the weight in each house there should be a floor household scale. This simple device will bring you undoubted benefits. Currently, in stores you can buy floor scales of domestic and foreign production, simple mechanical and electronic. It's easy to take your first step to the scale - a step to health.

Control weighing is best done in the morning before breakfast, after the toilet, morning exercises and shower. It is advisable to have a minimum of clothing. Before weighing, it is necessary to place the balance on a flat place on the floor, check the zero setting. It is necessary to stand on the scales in a stable position, with two legs located symmetrically with respect to the center of the scales and their edges. After calming down the pointer of the scales, read off the indications on the pointer and the scale of the scales. Remember the result, and when you get off the scale, write down the date and your weight on a check sheet.

To control the state of health, it is quite enough to weigh once a week, for example, on Sunday. Daily weighing makes sense only if you start a fairly intense fight against overweight.

Now let's find out what is normal and ideal weight.

Normal weight is considered to be determined by the formula: human height (in cm) - 100.

However, this value is only an approximate maximum guideline.

It is necessary to strive for a lower weight value, called ideal, the value of which takes into account corrections for gender, age and body type.

An approximate guide value for ideal weight can be determined from the normal value by subtracting 10% of this value for men and 15% for women.

Here are the values ​​​​of the ideal weight of men and women.

Ideal weight for a man

Notes:

1. The first value of the ideal weight corresponds to the calculated value, the second to the corrected value for the light body type, the third for the average body type, the fourth for the heavy body type.

2. An approximate figure for each weight for height not listed in the table can be obtained by averaging the values ​​​​of the two values ​​\u200b\u200bgiven.

3. Adjusted ideal weight values ​​are based on the minimum weight level. This is indeed the ideal to strive for.

4. In reality, for each body type, there is a spread in the ideal weight values.

5. Many people prefer to record the results of regular weighing in a special diary, which indicates the dates of weighing and weight indicators.

6. The tables in this chapter are examples. You should not try to necessarily reach the minimum limits of your weight. The limit of your own weight must be chosen for yourself so that you feel energy and strength in yourself.

And now, according to the table, we find out how much weight a man with a height of 180 cm can have.

Such a man can have a normal weight of 80 kg, an ideal calculated weight of 72 kg, for a light type, the adjusted weight is 63–67 kg, for an average type, 66–72 kg, for a heavy type, 70–79 kg.

In addition, according to the results of regular weighing, you can always draw conclusions about the state of your health.

It's great when at 20 and at 70 people keep their ideal weight.

❧ Compliance during years ideal weight means that a person adheres to the right lifestyle, all physiological processes in the body proceed normally and the person is healthy.

A sharp weight loss or a sharp weight gain with the same diet or with increased nutrition due to a sudden incomprehensible need for additional nutrition and a sharply aggravated appetite can only mean one thing: there are disturbances in control processes in the body. A serious illness has set in.

❧ The tendency to a sharp change in weight is a signal that it is time to consult a doctor to find out the specific reason.

SHARP WEIGHT LOSS can occur with cancer, diabetes, diseases gastrointestinal tract, lung diseases, helminthiasis and other serious diseases.

RAPID WEIGHT GAIN can be observed with endocrine diseases, with the accumulation of fluid in the body as a result of diseases of the heart and kidneys and in other cases.

But a gradual increase in weight, not caused by any diseases, is observed in those people who like to eat tasty, a lot, often and do not burden themselves with any significant load. For example, after an active vacation, a person loses weight and feels cheerful and strong. And when vacation comes down to just enhanced nutrition, lying on the couch watching TV all day and sleeping for a long time, the person gains weight and feels lethargic.

Excess weight recorded by you when weighing, accumulated as a result of overnutrition and lack of sufficient motor load, can only mean one thing: goodbye health. No matter how tasty it was to eat, you will have to pay with your health a little earlier or a little later.

You can also assess your condition using the GROWTH-WEIGHT INDEX.

You need to know exactly your height and weight.

To calculate this index, you need to multiply your body weight (in kg) by 100, and then divide the resulting product by your height (in cm).

An index significantly lower than 37 may be in patients with malnutrition caused by various diseases that affect metabolism, or with insufficient and inadequate nutrition for a long time.

The normal ratio between height and weight is expressed by a number that lies in the range of the index from 37 to 40. This is the ideal to which one must strive.

❧ If the height-weight index exceeds 40, then you have too much weight for your height..

Another way to check your status is to use the END index. Measure your waist and hips with a flexible meter. Divide the first number by the second. If the index for a man is more than 0.95 and more than 0.85 for a woman, then there are problems with being overweight.

It is even easier to determine the presence of excess fat using a pinch test. Grab a fold of skin on the abdomen with a pinch. If the fat fold is more than 2.5 cm, then you have problems with being overweight.

Another easy way to check your physical condition- a critical look in the mirror. Undress in front of a mirror. Look: do you have significant fat folds that spoil your figure? Stand up straight. Tilt your head. Can you see your lower belly? Stand up straight and try to lightly press your back against the door. If your body touches the door at five points (back of the head, shoulder blades, buttocks, calves and heels) or three points, then this is normal. If, with a straight body position, you manage to touch the door only with your buttocks, then there are problems with being overweight.

When you are unable to regularly check your weight due to lack of time, you should pay attention to how your clothes fit. If the clothes are getting tighter and tighter, the belt has to be spaced out, you have to buy larger clothes, then you have a problem with being overweight.

If your clothes are becoming more and more loose, hanging on you, you have to buy a smaller dress size, and you lead a normal diet and motor activity, you should definitely consult a doctor. Sudden weight loss can be caused by a serious illness.

Scales can help some people in the fight against excess weight, while others will only get in the way. Such people get hung up on the readings of the scales during daily weighing and get upset if the arrow is standing still or moving too slowly to the left. A person begins to inspire himself that nothing works out for him and that he needs to stop fighting. In fact, you need to think about what actions you can effectively reduce your weight.

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 formulas for calculating 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 only suitable 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, the ideal body weight for girls should be calculated as follows:

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 example: 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:

For example: 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 small overweight. 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. It has to do with the slowdown 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?

It is necessary for every modern person to know how to calculate body weight and draw the right conclusions about the state of the indices, which show whether you have obesity or a predisposition to this disease. We offer you basic methods on how to calculate your body weight using simple formulas and tables.

Human body weight and its excess

Human body weight - the most important indicator our state of health, which determines whether nutrition meets the needs of the body. Distinguish between normal, overweight or underweight.

Naturally, obesity necessarily implies the presence of excess body weight, formed due to the accumulation of fat.

However, the concept of excess body weight is not synonymous with obesity and has an independent meaning. So, many people have a slight excess of body weight, not reaching the degree of illness, that is, obesity. In addition, excess body weight is due to developed muscles (in athletes or people engaged in heavy physical labor) or fluid retention in the body in a number of diseases.

In the same way, the lack of body weight does not always reach the degree of the disease - protein-energy deficiency. Many methods have been developed to control body weight. Usually they are aimed at comparing height and body weight and comparing the result with normative indicators calculated on the basis of various formulas or given in special tables. Earlier in domestic medicine, body weight exceeding the norm for a given adult by 5-14% was called excessive, and exceeding the norm by 15% or more indicated obesity as a disease. At the same time, in foreign medical practice obesity was considered excess body weight, reaching 20% ​​or more compared with the norms adopted in tables or obtained by calculation formulas. As a result, the prevalence of obesity in our country was higher than in other countries.

Brock's formula

Until now, Broca's formula, proposed by the French surgeon and anatomist Paul Broca, is still popular. According to this formula, the following indicators of the norm are obtained.

Normal body weight

For men of average build:

• with growth up to 165 cm, the norm of body weight in kilograms is equal to growth in centimeters minus 100;
• with a height of 166-175 cm - minus 105;
• with a height of 175 cm or more - minus 110.

Obesity or obesity: methods for assessing body weight

In women of appropriate height and build, the proper body weight should be approximately 5% less than that of men.

A simplified version of the calculation is also proposed:

• for women under the age of 35, normal body weight should be equal to height in centimeters minus 110;
• over 35 years old - height in centimeters minus 100.

In people with narrow chest(asthenic physique), the data obtained are reduced by 5%, and in people with a wide chest (hypersthenic physique), they increase by 5%.

I note that the formula “height in centimeters minus 100”, popular due to its simplicity, used for people of any height, distorts Brock's indicator.

How to determine BMI: body mass index calculation

Currently, a very informative indicator is used in international practice - the calculation of body mass index (BMI), also called the Quetelet index. In 1997 and 2000 WHO recommended that body weight be assessed based on BMI, with which Russian doctors also agreed. However, the report "Prevention, diagnosis and treatment of primary arterial hypertension in Russian Federation» (2000) experts of the Scientific Society for the Study of Arterial Hypertension, the All-Russian Scientific Society of Cardiology and the Interdepartmental Council for cardiovascular diseases amended: as the lower limit of BMI, which characterizes normal body weight, it is proposed to consider 20 kg / m 2 instead of the WHO recommended indicator of 18.5 kg / m 2 shown in the table. The reason for this proposal is simple: a number of studies have found that people with low BMI values ​​(less than 19-20 kg / m 2) have higher mortality not only from oncological diseases or chronic obstructive pulmonary disease, but also from cardiovascular disease.

Before determining the BMI, the available body weight in kilograms is divided by the height in meters squared:

BMI = body weight (in kilograms) / (height in 2 meters).

Body mass index table

The body mass index table allows you to assess the state of your health and provide possible risks development chronic diseases. It gives a description of the indicators of body mass index (BMI). We warn you that the assessment of body mass index should be carried out by a qualified doctor, taking into account your individual characteristics.

I will demonstrate the application of the formula on specific example. Suppose your height is 165 cm and your weight is 67 kilograms.

1. Convert height from centimeters to meters - 1.65 m.
2. Square 1.65 m - it will be 2.72.
3. Now 67 (weight) divided by 2.72. Your result is 25.7 kg / m 2, which corresponds to upper bound norms.

You can not calculate BMI individually, but use a special table developed by D. G. Bessenen in 2001.

Please note that it has a number of shortcomings: there are no BMI values ​​​​below 19 kg / m2, and BMI characterizing different degrees obesity are given in abbreviated form in the table.

Table - Body mass indices in accordance with height and body weight:

Waist hip index

In recent years, it has been found that the risk of developing a number of diseases depends not only on the degree and duration of obesity, but also on the nature of the distribution of fat in the body.

Depending on the localization of fatty deposits, there are:

• abdominal obesity (it is also called visceral, android, "upper", like "apple", according to the male type) - excess fat is located mainly on the abdomen and in the upper body. This type of obesity is more common among men;
• gluteofemoral obesity (it is also called gluteofemoral, gynoid, "lower", like "pear", according to the female type) - excess fat is located mainly on the hips, buttocks and in the lower part of the body, which is typical for women.

At abdominal obesity even minimal excess body weight increases the risk of cardiovascular disease and death from them. Increasing chance coronary disease, as well as its three main risk factors: arterial hypertension, diabetes Type 2 and lipid metabolism disorders (increased blood cholesterol and other indicators). Combination listed diseases and conditions is called the metabolic syndrome. Its treatment, including with the help of diet therapy, is a task of paramount importance. Moreover, treatment is indicated not only for diagnosed abdominal obesity, but also for a significant excess of body weight (BMI - 27-29.9 kg / m2), if fat is deposited mainly in the upper body.

Waist hip index- this is the ratio of the circumference of the waist (measured above the navel) to the largest circumference of the hips (measured at the level of the buttocks).

On the contrary, gluteofemoral obesity is not associated with a pronounced additional risk and threatens with minimal medical consequences. His treatment is mainly cosmetic. I note that we are talking about obesity without concomitant diseases especially without type 2 diabetes and hypertension.

To determine the type of obesity, it is necessary to determine the waist / hip index (WHI).

Only waist circumference can be measured. It is recognized that the risk of developing metabolic syndrome:

• moderately increases with a waist circumference of 80 cm or more - in women, 90 cm or more - in men;
• increases sharply with a waist circumference of 88 cm or more - in women, 102 cm or more - in men.

Modern data require new approaches to assessing body weight. In particular, underweight has been found to be a risk factor for increased mortality from certain noncommunicable diseases. The concept of adipose tissue as metabolically inert, being exclusively an energy depot, has also changed. It has now been established that adipose tissue is a diffuse endocrine gland that produces a number of hormones and biologically active substances.

Table - Biologically active substances secreted by adipose tissue:

Leptin and obesity

Separately, it is worth dwelling on leptin, discovered in 1995, a hormone produced by fat cells. Its blood level reflects the energy reserves of adipose tissue, affects appetite, energy intake and expenditure, and changes the metabolism of fats and glucose. Leptin and obesity are closely related: this substance slows down the metabolism, but when deficient, it can cause a malfunction in the body.

According to the obtained scientific data, a positive role in normal operation the body is played only by excess body weight, which has not reached the degree of obesity.

Lack of fat reserves and leptin deficiency can impair reproductive function in women with severely reduced body weight, for example, after therapeutic fasting or when anorexia nervosa which is often accompanied by amenorrhea. No need to think that science is trying to rehabilitate obesity.

Thus, women with preserved menstrual function and overweight have a lower likelihood of developing breast cancer, bone resorption (destruction of bone tissue) and postmenopausal osteoporosis. No negative effect of excess body weight (without obesity) on lipid and carbohydrate metabolism, as well as on the level of blood pressure in practically healthy men and women. Foreign studies conducted by insurance companies stated the lowest mortality rate among people whose body weight exceeded the norm by 10%.

Specialists of the Research Center for Preventive Medicine of the Ministry of Health of Russia, who have been observing men and women aged 40-59 for 20 years, have found a relationship between life expectancy and BMI. Thus, 50% of the "thin" and "full" examined died earlier than those who had an average BMI - from 20 to 30 kg/m2. At the same time, “thin” men and women died earlier than “full” ones. Why this happens and whether people with low body weight have other risk factors is still unknown.

The problem of excess weight is very acute today. Unfortunately, the number of obese people is growing every day. But who said that you have to put up with it? No, it is extremely necessary to deal with this problem, and you need to start as soon as possible. Just do it wisely, trying not to harm the already affected health. We will tell you where excess weight comes from and what methods for losing weight are most effective.

Before you start fighting for slim figure and healthy body, you need to know exactly what are the main factors from our Everyday life cause fat to accumulate in various places of the body:

1. Wrong and unbalanced diet. Usually, overweight people consume many more calories daily than their body uses. This is the main reason for the onset of obesity.
2. Sedentary lifestyle. Scientists have long proven that a constant sitting or lying position of the body gradually leads not only to the formation of excess weight, but also to the development of many serious diseases.
3. genetic predisposition. Unfortunately, this is also an important factor. But do not think that if you are disposed to be overweight, then nature itself has determined you to be fat. No, it's not. If you learn to maintain your health and follow the basic rules healthy lifestyle life, fullness is not terrible even if there is a tendency to it.
4. endocrine disorders. This factor is rather a consequence of the first two reasons on our list. The presence of such disorders can cause irreversible consequences that require long-term treatment, possibly even in a hospital.
5. Constant stress. We've all heard that nerve cells very difficult to recover, and disruption nervous system slows down many processes in the body. Take care of your psychological health and try to attach importance to minor troubles as little as possible.

Overweight and health - what could be the consequences?

The presence of excess fat in the body leads not only to unaesthetic appearance, but also entails the appearance of serious ailments. Many obese people do not know or simply do not want to know about them:

• fat and carbohydrate metabolism is disturbed, which makes all organs work to the limit;
• increased blood pressure and, as a result, the development of hypertension;
• circulatory disorders;
• atherosclerosis;
• heart attack;
• stroke;
• fatty liver (steatosis);
• whitening of the gastrointestinal tract;
• infertility;
• hormonal imbalance;
