Body mass index is important parameter, which allows you to assess the health status of the stronger sex.
Abrupt changes in body weight always adversely affect the functioning of body systems, therefore, both weight gain and weight loss are considered a deviation from the norm. However, a rapid increase in body weight is considered more dangerous - obesity.
For men, being overweight threatens with the following consequences:
- diabetes;
- cardiovascular diseases;
- decreased immunity;
- violation of the respiratory system;
- loss of stamina;
- decreased performance;
- erectile disfunction;
- infertility.
Particularly frightening of the stronger sex is the likelihood of developing impotence and the loss of the ability to reproduce against the background of obesity. After all, weight gain is due to a malfunction in metabolic processes and a violation hormonal background.
Weight loss also leads to serious complications and worsens the health of men, manifesting itself in the following consequences:
- weakening of the body's defenses;
- susceptibility to disease viral nature(SARS, flu, etc.);
- tendency to dystrophic pathological processes.
In view of this, it is important that the BMI in men is consistent with the norm. Maintaining a normal body weight will help to maintain for a long time not only beautiful figure but also health.
BMI parameter value
Body mass index is a special indicator that displays the correspondence of a person's weight and height.
This parameter is different for each individual patient and depends on many factors. When assessing BMI, the following are taken into account:
- gender;
- age category;
- degree of development muscle mass;
- hormonal status;
- Lifestyle.
The BMI rate for men is always higher than for women. For representatives of the stronger middle-aged sex, this indicator is higher than for old people or adolescents. Below 
the values of the body mass index parameter are given.
- BMI under 16 indicates excessive thinness in men.
- A BMI of 16 to 18.5 indicates moderate underweight.
- BMI from 18.5 to 24.9 is an indicator of the norm.
- A BMI of 25 to 30 is a symptom of non-critical (moderate) excess weight.
- BMI from 30 to 35 typical for obesity of the 1st degree.
- A BMI of 35 to 40 indicates grade 2 obesity.
- A BMI of 40 and above is a sign of critical overweight - obesity grade 3.
In the event that the BMI for men exceeds the number 40, there is a serious threat to life and surgery is required to eliminate the problem of severe obesity.
The likelihood of developing diseases against the background of obesity can be determined by assessing the value of BMI and waist volume. After all, a large weight is not always a sign of hormonal failure and metabolic disorders. For example, men who do weightlifting can have a lot of muscle mass and still be completely healthy.
If the BMI parameter is higher than normal and at the same time the circumference in the belt reaches 102 cm or more, then the risk of developing diseases against the background of obesity increases significantly. When the body mass index is 35 kg / m2 and above, and the waist is from 100 cm, then this indicates a critical condition and danger to life.
In order to assess the ratio of weight in relation to height, it is necessary 
use this formula:
I = M: (PxR)
In this formula, I is the body mass index (kg / m2), M is the mass (kg), P is the height (m). For example, let's calculate the BMI for men weighing 90 kg and height 187 cm:
I = 90: (1.87 x 1.87) = 25.7 - which is the norm.
This formula is widely used in practice in medicine in order to establish deviations in the state of health associated with impaired body weight. However, it is important to understand that BMI for men may differ from case to case. V adolescence this diagnostic method is not used. It is also useless to rely on normal values when measuring BMI in men who are involved in weightlifting. For developing organism parameters will always be lower, and higher for athletes with a strong physique.
Weight correction
If the body mass index begins to exceed the norm or decreases, then it is imperative to seek the advice of a specialist. In order to normalize weight, patients are prescribed a special optimally suitable diet, as well as an individual diet. With a slight excess of body weight 
men are recommended:
- reduce portions of food and the frequency of meals;
- refuse foods that provoke weight gain;
- eat more grains, vegetables and fruits;
- observe the diet, eat at the same time, do not eat at night;
- increase physical activity;
- monitor sleep and rest.
If the BMI for men is below normal, but the underweight is not critical, then the following doctor's advice should be followed:
- increase portions and eat more often
- increase the calorie content of dishes by including protein foods in the diet;
- fulfill physical exercises that contribute to an increase in muscle mass;
- observe a rest and sleep regimen.
In case of critical weight gain or weight loss, a specialist will prescribe appropriate treatment, since only diet and regimen will be ineffective for correcting body weight and preventing the development of complications.
The results of calculating BMI are not suitable for assessing the weight of professional athletes, pregnant women, as well as people suffering from edema and other disorders, leading to an incorrect assessment of the initial data.
Weight ranges in this calculator are calculated for height, according to the methodology of the World Health Organization (WHO).
The very method of assessing weight by BMI is intended for the primary detection of underweight or overweight. Obtaining an assessment that is different from the norm is a reason for contacting a nutritionist and endocrinologist in order to conduct an individual assessment of weight and develop recommendations for its correction, if necessary.
The ideal weight range (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 of normal weight looks not only healthy, but also the most attractive. If you are adjusting your weight, then it is highly discouraged 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 weight loss disorder.
Weight loss is also typical for professional models, gymnasts, ballerinas or girls who are overly addicted to weight loss without the supervision of a nutritionist. Unfortunately, this can sometimes lead to health problems. Therefore, weight correction in this range should be accompanied by regular medical monitoring.
Norm shows the weight at which a person has the maximum chances of staying healthy for 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, those of normal weight tend to be in well-being even after intense physical exertion.
Preobesity speaks of 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. V in this case light weight correction is recommended to normal, or to values close to it. Also, it will not hurt to consult a dietitian doctor.
Obesity- index chronic illness associated with excess body weight. Obesity invariably leads to problems with the 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 required analyzes and defining its type. Uncontrolled dieting and serious physical activity it is not recommended for obesity, as this can provoke additional problems.
Answers on questions
What is the ideal weight for me?
The calculator calculates the weight range that is ideal for you based on the specified 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 received estimate?
Yes. Adult weight estimates are based on authoritative research from the World Health Organization (WHO). Evaluation of weight from birth to 18 years is carried out according to a separate special method, also developed by WHO.
Why gender is not taken into account?
The BMI of adults is estimated in the same way for both men and women - this is justified by the results of statistical studies. At the same time, for weight estimation, gender and age are of fundamental importance.
Some other weight calculator will give you a different result. What to believe?
Exists great amount calculators designed to estimate weight based on height and gender. But their formulas are usually developed in the last century. by individuals or teams based on criteria that you do not know or do not suit (for example, formulas for evaluating athletes).
The WHO recommendations used in this calculator are designed for common modern people, subject to conditions modern life, advances in medicine and based on fresh observations of the population of all continents of the planet. Therefore, we only trust this technique.
I believe the result should be different.
The assessment is made solely on the basis of the data you provide for height and weight (as well as age and gender for children). If you receive unexpected results, please double-check all the entered data. Also, make sure that you do not belong to any weight that cannot be estimated through BMI.
My result is a lack of body weight, but I still want to lose weight
This is not unusual, many professional models, dancers, ballerinas do just that. However, in this case, it is recommended to lose weight only under the supervision of a dietitian 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 doing fitness, after consulting a good nutritionist.
Please note that some elements of the figure are practically not amenable to correction only with the help of fitness, exercise, diets, or their combination. 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 disagree
If you are an athlete with increased muscle mass, then BMI weight estimation is simply not intended for you (this is mentioned in). In any case, for an accurate individual weight estimate, consult a dietitian - only in this case you will receive an authoritative result with a doctor's seal.
Why am I considered too thin or fat when my weight is normal?
Pay attention to the personalities and weights of those people who bother you. As a rule, they judge exclusively by themselves: subjectively. Fat ones always consider the thin ones to be skinny, and the thin ones always consider the fat ones to be fat, moreover, both of them can have a weight within healthy norm... Consider and social factors: try to exclude or suppress those judgments in your address that are based on ignorance, envy or personal dislike. Trustworthy is only an objective assessment of BMI, which clearly indicates the norm, excess or deficit of mass; and only trust supportive people in your weight class or your doctor for your worries about your figure.
How to calculate body mass index (BMI)?
The weight indicated in kilograms must be divided 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
Being overweight or underweight is known to have a negative impact on health. People who have a deficiency of adipose tissue or an excessive amount of it are at risk for serious illnesses shortening life expectancy. Many methods have been developed to determine the compliance of weight with the norm according to certain indicators, one of which is the body mass index (BMI).
Body mass index is a value that allows you to assess the degree of correspondence between the mass and height of a person and determine whether the mass is overweight, normal or insufficient. This value is also called the Quetelet index in honor of its creator, the Belgian Adolphe Quetelet, who developed the method back in the 19th century.
The calculation formula is very simple:
I = m / h 2, where m is body weight in kilograms, and h is a person's height in meters.
To illustrate what BMI is, take, for example, a person 185 cm tall and weighing 96 kg. We translate the height from centimeters to meters, we get 1.85 m.Let's square this value: 1.85 x 1.85 = 3.42. Dividing the weight by this indicator, we get the desired value of the Quetelet index: 96 / 3.42 = 28
Since now most people use a calculator for calculations, it is more convenient to calculate the body mass index using this algorithm: we divide the mass in kilograms by the height in meters, and then divide the result by the height in meters.
For our example: 96 / 1.85 / 1.85 = 28
The calculated value does not tell us anything yet. To find out how much it corresponds to the norm, it is necessary to correctly interpret the result.
Interpreting the result
The normal body mass index is between 18.5 and 24.9. In more detail, the calculation result can be estimated using the table.
Body Mass Index (BMI) Table
If we turn to the example above, then a calculated BMI of 28 indicates the presence of overweight, which is not yet classified as obesity, but already carries increased risk the incidence of "diseases of the century" - cardiovascular, oncological, diabetes mellitus. However, one should not rush to conclusions, BMI is not indicative in all cases.
The main advantages of the method for determining the normal weight by BMI is its simplicity and versatility; people of any gender and age can use it. However, these advantages have their downside, and the results of the BMI method can not always be trusted. The main disadvantages of assessing body condition by BMI are the lack of accounting for:
- body type;
- the ratio of fat and muscle mass in the body:
- distribution of adipose tissue in the body.
Let's consider each of these shortcomings of the method in more detail.
Influence of body type
In terms of specific gravity, bones are much heavier than muscle, and even more so - adipose tissue, which is the lightest in the body. Therefore, the greater the volume of the musculoskeletal and muscular systems, the less fat will be with the same body weight.
There are three body types:
- asthenic (ectomorphs);
- normosthenic (mesomorphs);
- hypersthenic (endomorphs).
Ectomorphs have a narrow backbone, thin bones, and a relatively small amount of muscle. Endomorphs are characterized by a wide skeleton, thick bones and significant muscle mass. Mesomorphs for these indicators occupy an average position. All of these types are normal variants. However, the BMI norm does not take into account differences in body types. This method is most suitable for mesomorphs, but asthenics and hypersthenics, using it, may interpret their results incorrectly.
A conditional person with a BMI of 28 from the above example may have a completely normal or very slightly overweight if he belongs to pronounced endomorphs. And, conversely, if it is narrow in the shoulders and hips, thin-boned, then a body mass index value of 28 for it may mean the presence of obesity.
Despite the rather large permissible range of normal BMI values (18.5 - 24.9), the error in determining the weight norm for people different additions can be quite significant. The error is especially large at the boundaries of this range. So, for example, a hypersthenic person with a body mass index of 18.5 is likely to be in a state of exhaustion, and an asthenic with a BMI of about 25 will have significant excess weight.
Due to this lack of the BMI system, ectomorphs and endomorphs are advised to make adjustments in accordance with the characteristics of their body type, or resort to other methods of assessing body weight.
Percentage of fat and muscle mass
The formula for calculating BMI takes into account only two indicators - height and body weight. However, weight characterizes the state of the body very conditionally. The figures of people of the same height and weight can differ dramatically. An athlete with voluminous muscles and small body fat, can weigh as much as a person of the same height with underdeveloped muscles and a lot of adipose tissue.
For health and appearance more important indicator is not weight, but the percentage of fat and muscle in the body. After all, weight is a quantitative indicator that does not take into account the qualitative composition of the body.
Since BMI does not take into account the percentage of adipose tissue, it is better not to use this method for people with a significant predominance of muscle over fat mass. Weightlifters, bodybuilders, when trying to determine their ideal weight by body mass index, risk getting results that are far from reality.
Localization of body fat
Adipose tissue in the body can be localized in the subcutaneous layer, as well as in abdominal cavity where it builds up around internal organs... The most dangerous is the second type of obesity - abdominal, when fat is deposited inside the abdomen. Exactly abdominal obesity most often accompanies diabetes mellitus, hypertension, atherosclerosis, which are the causes of heart attacks and strokes.
Weight classification by BMI does not take into account the type of obesity, and this is one of its main disadvantages. This method recognizes the risk concomitant diseases directly proportional to the degree of obesity. Although in reality, abdominal obesity is more dangerous, even if its degree is lower than with subcutaneous fat localization.
Abdominal obesity is typical for most men, as well as those women who have an "apple" body type. According to statistics, coronary heart disease, heart attacks, stroke are more common in men and women "apples" in postmenopausal women. Therefore, persons belonging to these risk groups should, in addition to determining the permissible weight by body mass index, also use the following formula for verification: the waist in cm divided by the height in cm should not exceed 0.5.
Other shortcomings of the method
In addition to the fact that the method of assessing weight by BMI does not take into account body type, percentage and localization of adipose tissue in the body, it requires some more amendments.
So, for example, this method is not applicable to pregnant women and children. Also, the body mass index may not be correct for women who have a significant percentage of their body weight in the mass of the mammary glands.
Based on the results of research by American scientists, conclusions have been drawn that cast doubt on the upper limit of the BMI norm, which is 24.9. In the course of long-term observations, it was found that men live longer, whose BMI is close to 26.
The risk of disease when the BMI deviates from the norm
Despite all the shortcomings of the classification of weight by body mass index, in most cases it quite accurately allows you to determine the degree of compliance with the norm and the risk of concomitant diseases.
With a weight corresponding to a BMI of less than 16, there is a pronounced underweight and depletion of the body. Often this body mass index is present in persons suffering from anorexia nervosa... Among women reproductive age this degree of depletion is usually accompanied by cessation menstrual cycle... Immunity is greatly weakened, as a result of which the risk increases infectious diseases, escalate chronic diseases... The health risk at these BMI values is very high. Required Urgent measures for the treatment of concomitant diseases and weight normalization.
In the BMI range of 16-16.9, signs of underweight and wasting are less pronounced, but amenorrhea is often observed in fertile women. The health risk associated with this underweight is classified as high. It is necessary to take measures to normalize weight.
With values of 17-18.34, weight is considered reduced, and the health risk is increased. Bringing body weight into line with the norm is recommended by doctors.
If with a BMI below normal, the likelihood of diseases associated with a decrease in immunity and depletion of the body is increased, then with a weight exceeding the norm, the risk of heart disease, blood vessels, joints, metabolic disorders increases.
With values of 25-29.9, weight is considered overweight, and the health risk is also increased. Changes in diet and lifestyle are recommended, aimed at normalizing weight.
BMI 30-34.9 corresponds to the I degree of obesity in terms of body mass index, which is characterized by the appearance of shortness of breath when walking fast. If you do not take measures to reduce weight, then hypertension develops, the risk of diabetes is high.
With an index of 35-39.9, the second degree of obesity is diagnosed. This condition is characterized by: shortness of breath, swelling of the legs, fast fatiguability... The heart, arteries and veins, joints of the legs and spine are affected. Disorders may appear in women reproductive function... Disease risk of cardio-vascular system, musculoskeletal system, organs internal secretion very high. Weight loss therapy required.
With a BMI over 40, morbid obesity (III degree) is diagnosed, which is associated with an extremely high risk to health and poses a threat to the patient's life. Treatment of morbid obesity is difficult and is often done by surgery to reduce the volume of the stomach.
Determination of the ideal weight by body mass index, although it has a number of disadvantages, but due to the versatility and simplicity of this method, it is by far the most popular.
Body Mass Index Calculator is a simple way that anyone can use to find out within a few seconds if their weight is within normal limits. Body mass index (BMI) is a coefficient that allows you to calculate a person's body weight in relation to their height online. Calculating BMI is very easy, you only need to apply a simple formula. BMI does not measure body fat, but it effectively concludes that a person is not at risk of being obese, overweight, or underweight. BMI for men is calculated in the same way as for women.
BMI formula
A simple formula for calculating BMI is given below:
BMI = body weight (kg) / height (m) 2
How to calculate BMI? - it is enough to divide the weight of a person in kilograms by his height in meters, squared, for example: if a person's height is 165 cm, then it needs to be multiplied by 1.65 x 1.65 = 2.7225.
Then the weight of a person, for example, 60 kg, is divided by the result obtained: 60 / 2.7225.
This will give you a BMI of 22.03.
Moreover, when calculating the age does not matter. Online you can calculate the body mass index for both women and men.
Interpreting BMI Results
V International classification BMI for adults are calculations by which you can determine the norm or deviation from it. If BMI:
- below 16.0 - malnutrition is observed in a person;
- 16.0-17.0 - depletion of the body (often due to a serious illness);
- 17-18.5 - low weight;
- 18,5-25,0 - normal value;
- 25.0-30.0 - overweight;
- 30.0-35.0 - 1 degree of obesity;
- 35.0-40.0 - 2 degree of obesity;
- above 40.0 - 3 degree of obesity.
Another way to check if you are in the weight norm is to measure your waist circumference. For women, the waist circumference in the range of 80-88 cm already indicates overweight... Waist more than 88 cm, in turn, indicates obesity. Men with a waist circumference of more than 94 cm are overweight, we can talk about the initial degree of obesity when a man owns a waist with a circumference of 102 cm. Obese people are most often prone to the following ailments: stroke, heart attack, arterial hypertension, some types of cancer, diseases of the musculoskeletal system.
The calculation of BMI in children is done in the same way as in adults, only the data obtained are compared with the average results of this age group... Instead of defining intervals that indicate obesity, overweight, and underweight, BMI in children compares the scores of a specific gender and a specific age. Studies in the UK show, for example, that girls aged 12-16 have a much higher BMI than boys in the same age range.
Advantages and disadvantages of BMI
The huge advantage that BMI is characterized by is the fact that it is easy to calculate using a formula. Studies show that a BMI of 18.5-25 is observed in people who use for a long time good health and have the lowest incidence of diet-related ailments such as type 2 diabetes or atherosclerosis. Thus, the coefficients deviating from the norm are valuable evidence for a person that he needs to take care of his health. But, unfortunately, BMI is within normal limits, not always a guarantee that you have a normal body weight. You may be at risk of latent obesity, which is most often diagnosed among people who are not physically active enough. In this case, it will be more effective to study the percentage of adipose tissue in the body. Also, an increased body mass index does not always indicate that you are overweight. It may be that an above normal BMI is the result of highly developed lean muscle mass with little fat. For example, athletes have high values BMI, but at the same time they are in the correct physical form... After all, muscles are heavier than the same amount of adipose tissue. Physically active people should focus more on measuring their body contours rather than monitoring their BMI results.
When calculating the BMI of people with a height below 150 cm and above 190 cm, they will not receive correct result moreover, this method is not suitable for weight control in pregnant women.
Scientists are thinking about introducing a classification of BMI indicators depending on geographic and cultural conditions.
Other methods for determining obesity
- Measurement of the thickness of skin folds (the degree of obesity depends on the thickness of the layer of subcutaneous adipose tissue);
- a measurement in which the bioelectrical impedance method is used (the passage of a current with a very small strength and voltage through the human body);
- measuring body density by weighing it under water (using the difference in fat and muscle density).
Health warning
The obtained BMI calculations do not indicate a person's health or illness, they indicate an increased risk of diseases associated with obesity.
The World Health Organization often uses body mass index to calculate the percentage of people who are obese or overweight. These calculations are especially important in Western countries, where obesity is the main disease of civilization. You already know how to calculate BMI. The result that you get may indicate that your body is susceptible to illness due to an improper diet. This can simultaneously be a good motivation for you to make changes in your diet and lifestyle.
BMI is used to assess the risk of various dangerous diseases: atherosclerosis, ischemic disease heart, stroke, diseases of the musculoskeletal system and even cancer. All these diseases occur with obesity, and that is why the BMI calculator is an important tool that allows you to quickly calculate the body mass index of a person. Remember that the higher the BMI, the greater the risk of various diseases.
Before you deal with the hated extra pounds, you should find out at what weight the body will feel comfortable in terms of health. To objectively assess your own weight, to determine whether or not you have overweight, it is necessary to calculate the body mass index - an indicator that shows the optimal level of body mass in a particular case.
Too high or too much weight contributes to the development of heart disease, cardiovascular disease, and others. serious illnesses... The body mass index, or BMI, was developed by Belgian sociologist and statistician Adolphe Ketele in 1869. That is why this indicator is also called the Ketel index.
Body mass index (BMI) is calculated by the formula: Body mass index (BMI) = m / p 2, where
M - mass in kilograms, P - height in meters squared. For example: your height is 1.64 meters, your body weight corresponds to 60 kilograms. We square 1.64 meters - we get 2.6896 m 2. We divide 60 kilograms by 2.6896 m 2. Rounding off the value, we get 22.3. This indicator will be your weight indicator. By the way, in this case it is within the normal range.

Normal body weight is an average value, that is, a value that is observed in a specific group of people (of the same height, gender, age, etc.). However, the value of normal body weight is quite individual and depends on a number of factors (type of constitution, gender, race, age, height, etc.). There is no controversy about gender and height. But in terms of age, according to most scientists, weight completely stabilizes by about twenty-five years of age. It is at this age that the weight is normal. And this is where disputes arise. After all, body weight is not constant, it grows by about eight percent of the norm in most people, except for people in the elderly and old age(during this period, the weight decreases slightly). Therefore, the weight that is observed more often is considered the norm. But he's not perfect.
It has also been proven that the type of constitution has a strong effect on body weight. This takes into account three types of physique:
- Normosthenic type, which is characterized by proportional body size and harmonious development of bone muscular system.
- Asthenic type, which is characterized by a slender body and weak development of the muscular system, while, when compared with the normosthenic type, in this type the longitudinal dimensions of the body and chest prevail over the dimensions of the abdomen, and the length of the limbs over the length of the body.
- Hypersthenic type, characterized by good fatness, characterized by a long body and short limbs, and transverse dimensions body and abdomen relatively predominate over the size of the chest.
Average normal body weight values for assessing overweight and obesity are approximate. More accurately they can be calculated only by determining the percentage of adipose tissue in the body. Only the indicators of muscle and fat components in the total body weight can really show that excess weight is a consequence of obesity or due to highly developed muscles. But in real life, this question arises only if there is an insignificant excess of the weight of the norm. In addition, the standards for the percentage of body fat are quite individual in nature. When calculating it in any way, the indicator has a significant error.
When determining the indicator of normal weight, factors such as place of birth, race, climatic conditions in which their ancestors lived (heredity) are of particular importance. It has been proven that the concept of a biological norm for a North American is significantly different from that of a resident of Europe, Australia or Africa. Therefore, each population of people should focus on their indicators of normal body weight.
Before actively losing weight, you need to understand what you really need: you want to get rid of extra pounds or slightly correct the figure. In this case, it is important to take into account the weight and distribution of fat in various parts body. To do this, you need to divide your own waist by the volume of your hips in centimeters. If the value obtained is higher than 0.8, you need to think about it, since excess fat on the waist is more dangerous than its deposits on the hips and buttocks.
According to research data, the risk group includes women whose waist volume exceeds 88 centimeters, and men with an excess of 102 centimeters. But here one should take into account important point, completely fat-free female body will not function normally, so it makes no sense to completely get rid of fat. This is dangerous! Indeed, it is in this layer of fat in women that estrogens are found, which are responsible for well-being, and also preserve the elasticity and youth of the skin.
