Overweight can be observed in many people, especially since the introduction of fast food in the diet. In some, the degree of obesity is insignificant, in others, the stage of the disease is expressed in tens of extra pounds. The obesity table will help you calculate the body mass index for men and women, thanks to which you can find out the stage of painful fullness. In order to contact a nutritionist at an early stage, and not bring the set of extra pounds to the state of a deadly morbid phase.

What is obesity

Excessive formation and deposition of adipose tissue in the human body is called obesity or liposis. Excess fat accumulates in the subcutaneous tissue, omentum and other tissues of the human body. This process is a disease that is characterized by an increase in the total mass of the human body by more than 20% of the norm. Excess weight causes psychophysical discomfort. But the worst thing is that a large mass entails pathologies of the musculoskeletal, cardiovascular, reproductive and digestive systems.

Causes

The accumulation of excess body fat often occurs due to an imbalance between the intake of energy resources from food and their expenditure. Energy costs differ depending on the lifestyle of each person. When more calories come from food than the body consumes, the unspent nutritional resources are converted into fat. The source of extra pounds can be many factors, it all depends on the characteristics of the human body.

Causes of liposis:

• overeating (90% of cases);
• physical inactivity (70% of cases);
• endocrine diseases;
• metabolic disorder;
• diabetes.;
• hereditary predisposition;
• physiological conditions (pregnancy, lactation, menopause).

Types

To calculate the type of liposis, it is first necessary to know the weight rate according to height. A normal indicator of human body weight is the number obtained by subtracting the figure 100 from the height in centimeters. 15% for women and 10% for men must be subtracted from the value obtained. For a BMI corresponding to the average norm, it is considered to be an indicator from 18 to 25 kg / m2.

Depending on the indicators of the human body mass index, the stage of obesity is classified into 4 types:

• I - deviation from the normal value by 10–28%.
• II - deviation from the norm by 30–48%.
• III - excess of the prescribed norm by 50–98%.
• IV - difference from the normal indicator by 100% or more.

How to determine the degree of obesity

You can correctly calculate the degree of obesity using a special formula. When calculating BMI, the height and weight of a person are taken into account. The abdominal Quetelet index looks like this: IR = weight / height2. After the personal value of the human body mass index is obtained, it must be compared with the data of a special obesity calculation table in order to establish the individual stage of liposis.

Table of obesity by weight and height

How personal weight differs from the normal value is easy to determine on your own. For these purposes, there is a table for calculating obesity. Knowing your height and weight, you can calculate the presence of extra pounds, and at what stage is the pathological process of liposis. The number at the intersection of the height column with the weight value column will show the BMI.

The degree of obesity by BMI

The calculation of the indicators of the human body mass index is made by dividing one's own weight by the squared height in meters. The resulting number must be compared with the data in the obesity calculation table. Depending on the degree of obesity according to the body mass index, there is a classification that helps to determine at what stage of painful fullness a particular person is. The stages of overweight by BMI are shown in the table:

obesity classification

The pathology associated with the accumulation of extra pounds is divided depending on the causes, the nature of the distribution of excess fatty tissues, the body's ability to grow adipocytes. History taking, laboratory and hardware studies in the diagnosis of liposis of a certain type are carried out in order to prescribe the appropriate treatment. Obesity is classified by degree and by other indicators, such as:

• morphological systematization of body fat: hypertrophic or hyperplastic liposis;
• places of localization of fat deposits on the body: abdominal, gynoid or mixed type;
• forms of painful fullness depending on the genesis: endocrine, cerebral, drug-induced or alimentary obesity.

In men

The abdominal (android) type is conventionally referred to as the "apple". It refers to the male form of liposis, which is more common. About 40% of men in various forms are subject to the android type of painful fullness. With abdominal obesity, deposits accumulate in the abdomen and waist. The accumulation of extra pounds according to the upper type in men appears closer to the age of 30, and if this process is not stopped, it continues throughout life.

Among women

The gynoid type is conditionally called a "pear" and is more often observed in women due to hormonal disorders. Fat with this variant of painful fullness according to the female type accumulates in the thighs and buttocks. Fat deposits according to the lower type in women can accumulate not only with age with a slowdown in metabolism, but also after childbirth and during breastfeeding.

BMI - body mass index- reflects the state of human health. This indicator depends on the fat resources of the body and may correspond to the norm, be excessive or deficient. Many people have a body mass index that is far from optimal. No wonder BMI appeared in medical records as a key risk factor for morbidity and began to be taken into account in the diagnosis.

What is your body mass index?

According to WHO, half of the people on the planet die today not from dangerous infections, as in past eras. Fast food, overeating, stress, "sedentary" work and "couch" leisure have become the main enemies of man.

A whole generation of obese people has grown up and are doomed to type 2 diabetes, cardiovascular disease, osteochondrosis and many other dangerous ailments. The asymptomatic period of these pathologies can drag on for years, during which the body's strength will slowly but surely be undermined. About the destructive activity of a hidden disease and will warn an increased body mass index.

In turn, a lowered BMI will signal another deviation from the norm - the painful exhaustion of a person. This state of affairs should also cause concern. An organism with an insufficient mass of body fat is not able to normally cope with its functions and resist diseases. Deficiency of adipose tissue can be a sign of type 1 diabetes, osteoporosis, indigestion, breathing or mental problems.

In any case, the body mass index will allow you to catch yourself in time and start restoring your physical form. Of course, on the path to perfection, you will need to pull yourself together, get rid of bad habits, sacrifice destructive addictions. However, the game is worth the candle, because the most precious thing is at stake - your life.

How to calculate body mass index?

To find out this indicator, you need to determine your weight (in kilograms) and measure your height (in meters). Then the number indicating the weight should be divided by the number obtained by squaring the numerical expression for height. In other words, you need to use the formula that conveys the ratio of body weight to height:

BMI = M / R 2

(M - body weight, P - height in meters)

For example, your weight is 64 kg, your height is 165 cm, or 1.65 m. We substitute your data into the formula and get: BMI \u003d 64: (1.65 x 1.65) \u003d 26.99. Now you can turn to official medicine for the interpretation of BMI values:

• it does not take into account the ratio of muscle and fat mass, so BMI will not be able to adequately reflect the state of health of a bodybuilder involved in building muscle potential: once he calculates the body mass index using the Quetelet formula, and according to the results, he will be in the company of loose fat men;
• these calculations are not suitable for older people: for 60-70-year-old pensioners, somewhat overweight is not considered dangerous to health, so the BMI range for them can be extended from 22 to 26.

If you are not an elderly person and not a bodybuilder, then the Quetelet formula will quite cope with the assessment of the balance of your parameters. The magnitude of the error in this case does not interfere with understanding whether you are normal or not.

It should be borne in mind that the understanding of the medical community about the BMI norm may change over time. It already happened on the threshold of the third millennium, when the BMI index recommended by doctors dropped from 27.8 to 25. But Israeli scientists proved that a body mass index of 25-27 is optimal for men: with this index, they are provided with the greatest life expectancy.

With a normal body weight, the body feels as comfortable as possible. So nothing prevents the proper functioning of all organs and systems.

As soon as this "fine line" of ideal weight is violated, your "bouquet of diseases" can increase, as excess fat interferes with the work of all organs. The pressure on the legs also increases, and they begin to swell, shortness of breath may appear.

Therefore, try to watch your weight to be healthy. First you need to find out if your weight is normal or overweight (and if overweight, then what degree of obesity). These calculations will greatly help you choose the most appropriate diet and exercise.

Body mass index

So, you first need to find out your height and weight. With these data, you can start the calculations. This should be done according to the formula: B / P ^ 2 \u003d BMI (B - weight in kg, P - height in m).

And now more clearly:

1. Let's say your height is 170 cm and your weight is 60 kg.
2. We translate height into meters - 1.7 m.
3. Now we get the square of height: 1.7 x 1.7 = 2.89.
4. Now we divide the weight by the square of height: 60 / 2.89 \u003d 20.76.

If your BMI result is less than 19, this is a sign of dystrophy. You urgently need to gain weight. Dystrophy, like obesity, is dangerous to health. If your body mass index is between 19 and 25, your weight is ideal. If more than 25, you have problems with obesity.

Degrees of obesity

Now you can in more detail about what exactly your degree of obesity is. This will help to find out, again, the body mass index.

There are four degrees in total:

• First degree - BMI = 26-28.5.
• Second degree - BMI = 28.5-35.
• Third degree - BMI = 35-40.
• Fourth degree - BMI = more than 40

Abdominal index

These calculations are needed to find out how much your degree of obesity is detrimental to health.

To do this, you need to measure the volume of the hips and waist. Now substitute the results into the formula: T / B \u003d AI (T - waist, B - hips).

Let's say that your waist is 97 cm, and your hips are 93. We consider: 97/93 \u003d 1.04.

For women, the norm is an index less than 0.8, for men - 0.95. If your index is above this data, sound the alarm.

First degree

This degree is the most harmless. You still do not have so many extra pounds, so you do not notice any deterioration in health.

The organs have not yet undergone any changes regarding functions and structure.

Discomfort is possible only with regard to appearance: extra centimeters on the hips and waist, fat folds, etc.

If you make the necessary efforts, in a fairly short time you can normalize your weight.

Second degree

She's already tougher. You notice how the heart works with difficulty. The legs often swell, and tormented by varicose veins. But that's not all.

Lipid metabolism is disturbed in the body, limbs begin to deform due to heavy loads, pain in the joints and spine is felt.

In children, second-degree overweight can lead to disorders in puberty.

Third degree

In this case, all the above problems are only exacerbated. Added to this are:

• Drowsiness;
• fatigue;
• irritability;
• general weakness;
• constant hunger and thirst.

Obesity is a dangerous disease, because the harm that is caused to the body from excess weight is not immediately noticeable. Obesity does not always depend on heredity and age. Diagnosis made at an early stage is the key to quick and successful treatment.
Basically, everyone measures excess weight visually by an external factor that affects the change in the body. Statistics show that obese people are three times more likely to suffer from high blood pressure than thin people. Obese people are more likely to develop diabetes, about nine times higher, and obese suffer 40 times more. It's simple, the load on all human organs is growing along with an increase in obesity. Imagine that a backpack with a weight of 10 to 100 kg was hung on you, the load is colossal, it is impossible to move calmly and easily with this.

How to determine the degree of obesity

An easy way to determine the degree of obesity by the Quetelet index - which means body mass index, for this you just need to know your weight and height. You need to get on the scales on an empty stomach, measure your height at different times, then select the average mark. It happens that during the day the growth may vary slightly by 1-1.5 cm.

The formula by which you can find out the degree of obesity:

With a weight of 85 kg, and a height of 1.60:

Mbody (kg)/Height2 (m)

BMI=85/(1.6*1.6)=33.203

BMI, kg/m2 State
Less than 18.5 stands for underweight
18,5-24,9 indicates normal body weight
25-29,9 I st - overweight
30-34,9 II stage - obesity
35-39,9 II stage - pronounced obesity
40 or more III stage - severe obesity

Tables for determining the degree of obesity

Do not forget that the Quetelet indicator makes it possible to correctly evaluate the data not for all categories of people. Suppose athletes have muscle mass, which is also reflected on the scales, but not under the guise of fat. Therefore, before referring to this formula, one must understand that the indicators will be different. An athlete's BMI can also be high, as in overweight people, it's all about the muscles. Not always, people with the same BMI look the same.

Normal weight (HB) can also be determined using other indices. Each index has its own calculation formula. The height value is substituted in centimeters:

1. The Brox index is suitable for people with a height of 155 to 170 cm. HB is equal to height minus 100 (HB = height-100). The value is determined by ss 10% error;
2. Bernhard index. HB=height x chest circumference/240;
3. Breitman index. HB = height x 0.7-50 kg;
4. Noorden index. HB = height x 420/1000;
5. Taton index. HB=height-(100+(height-100)/20);
6. Oder index. HB = distance from the symphysis to the crown of the head x 2-100.

ICO- index of central obesity. This method determines excess fat in this way, the waist circumference in cm must be divided by the length of the hip circumference.

For women, the mark of 0.8 is considered the norm, and for men - 1. And the waist should not exceed: for women - 80 cm, for men - 94 cm.

How to measure your waist and hips

A thin person should measure the narrowest place with a centimeter tape. A full person should clasp the waist 2 cm above the navel. Hips should be measured at their widest point.

* m - body weight in kilograms -

* h - height in meters,

and is measured in kg/m2.

example BMI calculation:

with a height of 1.64 m and a weight of 72 kg:

72 / (1.64*1.64) = 26.77 kg/m2

in the modern world, the following standards have been adopted to determine obesity levels:

15 or less - Acute underweight

(sometimes 15-20) - Underweight

18.5-25 - Norm

25-30, - Overweight

30-35 Obesity 1 degree

35-40 Obesity 2 degrees

50 or more overweight

At 1 And 2 degrees of obesity patients, as a rule, do not have special complaints about their health. They just become less mobile and more tired. 1 And2 degree of obesity delivers mainly psychological problems to the patient, but just these obesity and are the most progressive. It is at this stage of overweight that you should think about the diet.
Sometimes it is enough to add a small but regular physical activity every day and remove the usual, but daily piece of bread, and in a month you will miss two kilograms. At 3 And 4 degrees of obesity the patient has a sharp deterioration in the general state of health.

There is shortness of breath at the slightest physical exertion or even at rest. At 3 degrees And 4 degrees of obesity may be disturbed by pain in the heart, tachycardia. There is a general decrease in performance.

Metabolic processes in the body are disturbed, the immune defense of the body is reduced, as a result of which the risk of rheumatism disease increases sharply. It is very easy to call a rheumatologist at home now. But it is better to do timely prevention.
Frequent headaches and weakness, drowsiness, constant fatigue. Constant nervousness, joint pain, bitterness in the mouth may indicate hepatosis of the liver.
At 2,3,4,5 degrees of obesity atherosclerosis, diseases of the heart, joints, liver and biliary tract, diabetes mellitus may develop.
Treating overweight is much more difficult than preventing it. It requires perseverance and consistency, regular exercise and strict diets.
But first of all, it would be worth determining what food is for you in your life?

Perhaps this is a reward or consolation, or perhaps an encouragement. All troubles from childhood.
A food diary will help you overcome this problem. This is well stated in the article "The Psychology of Obesity".

So again:

Degrees of obesity

• I degree of obesity - actual body mass exceeds the ideal by more than 29%,
• II degree of obesity - overweight 30 - 40%,
• III degree of obesity - overweight 50 - 99%,
• IV degree of obesity - overweight more than 100%.

Ideal weight formula

The body weight, which is obtained after subtracting 100 from the height in centimeters, is considered to be the ideal body weight. Features of the constitution of men are also taken into account, therefore, when calculating, men should take away another 10%, and women - 15%.

Body mass index

• BMI less than 15 kg / m 2- a large lack of body weight;
• BMI from 15 kg / m 2 to 18.5 kg / m 2- insufficient weight;
• BMI from 18.5 kg / m 2 to 25 kg / m 2- normal weight;
• BMI from 25 kg / m 2 to 29.9 kg / m 2- overweight;
• BMI from 30 kg / m 2 to 34.9 kg / m 2 - I degree of obesity;
• BMI from 35 kg / m 2 to 39.9 kg / m 2 -II degree of obesity;
• BMI 40 kg / m 2 or more - III degree of obesity.
