BMI-norm. What is it?

The problem of excess weight and harmony of the figure in ourtime excites almost every person. Everyone wants to look beautiful, and without a harmonious, aesthetically attractive body, to achieve this is almost impossible. In addition, overweight is often the cause of various diseases. Accordingly, a fat person is absolutely healthy by definition can not.

To control the weight, a specialan indicator called the body mass index (abbreviated to BMI), which is the ratio of the weight of a person and his height. With the help of this indicator you can determine the presence of extra pounds. It is calculated very simply: you need to divide the total body weight (in kilograms) into a square of growth (in meters). BMI is normal for both men and women - 22.

Unfortunately, not everyone understands that lack of weightas dangerous as its surplus. Of course, leanness often looks more decent than dangling fats, but it can bring many problems to the person suffering from it. These are, first of all, fragile, fracture-prone, bones and lack of menstruation in women. Of course, you can not start yourself, but you also need to remember that the BMI-norm should be observed. Strong distortions in both directions, nothing but harm, the body will not bring.

Exact match to an indicator such as BMI(norm) means that a person is in good physical condition and does not suffer from obesity or painful leanness. The main task of such people is simply to maintain the weight at the existing level, and also to strengthen the muscles with the help of physical exertion.

The importance of BMI can fluctuate between indicatorsfrom 25 to 27. This stage is called an unattractive word - "pre-fatigue." In this case, you can already beat the alarm and begin systematic work to reduce weight. To the same stage belong the values ​​of BMI from 27 to 29. People whose body mass index is within these limits, it is urgent to try to lose weight at least to the value of 25-27, so as not to go smoothly to the next - the first stage of weight redundancy. The term "obesity" (BMI above normal) means already a large enough stock of extra kilograms, which invariably entail the emergence of a whole bouquet of diseases. To prevent this is possible, losing weight by at least 5-10%. However, in order to completely restore the metabolism and bring the figure in order, most likely, without the help of a dietitian, you will not manage.

Those who ignored all warningsdoctors and did not bother with the problem of weight loss, quickly reach the next stage - obesity of the second degree. In this case, the specialist's help is already mandatory, because people alone can establish a culture of nutrition and cope with excess weight a person simply can not. In some cases, drug therapy may be required.

The third degree of obesity is the most neglected anddangerous of all, which were listed above. At times, the risk of cardiovascular and oncological diseases, as well as diabetes mellitus, increases. To combat such a mass, most likely, you will need drugs, and even surgical intervention.

As practice shows, the BMI indicator forwomen are often much more important than for men. Unfortunately, in most cases the representatives of the stronger sex do not consider it necessary to follow the figure. However, in order to avoid health problems, such a notion as "BMI-norm" should not be an empty sound for them.
