People who are not indifferent to their health, necessarily watch the weight. There are many techniques that help determine the ideal ratio of height and weight. However, few of the amateurs know what the Quetelet index or body mass index is. The works of Adolphe Quetelet in mathematics, astronomy and sociologists are known throughout the world. But for women, he, first of all, the creator of a unique formula, helping to keep himself in shape.
What it is?
Everyone who is going to lose weight, it is necessary to ask, what the Quetelet index or the body mass index. Without such information, one can get so carried away with a diet that this will lead to exhaustion and health problems.
The body mass index (BMI) is used by many nutritionists to determine the normal weight. Also, using a special formula, you can identify insufficient or excessive body weight.
To determine whether weight to growth, you need to divide the body mass into a height in meters squared. For example, 60 kg: (1,6m X 1,6m) = BMI 23,44. This is recognized as a norm that is not harmful to health.
What indicator should I adhere to?
The Quetelet index, corresponding to the normal weight, will help to part with many complexes, and cease to strive for a ghostly ideal and excessive leanness.
So, in people whose BMI is equal to 18,5-25 units, everything is in order. They just have to lead an active lifestyle and eat healthy food to keep fit.
If the BMI fluctuates between 16 and 18,5, you need to think about weight gain. These indicators are not critical, but still worth a visit to a nutritionist.
People who have the Quetelet Index dropped below 16 units most likely need medical attention. A similar pattern occurs in dystrophics and girls suffering from anorexia.
With BMI 25-30, we are talking about excess body weight. This situation requires a diet and active sports. Otherwise, BMI can grow to 30-35 units, and this is the first degree of obesity.
Usually people whose body mass index is 35-40 know that they have weight problems. This picture signals a second degree of obesity. A BMI exceeding 40 units is about the third degree.
Since the Quetelet index, corresponding to the normal weight, is a conditional indicator, it does not take into account the physique. For example, in professional athletes BMI is very high due to the large amount of muscle mass.
Therefore, you need to take into account the parameters of the body, as well as measure the percentage of fat in the body. For the last action in the home conditions you need special scales. By setting the growth rate, sex and age on such scales, you can find out how much fat is in the body, and how much muscle and water.
