The simplest formula for calculating the ideal weight is the formula of Broca: an ideal weight in kilograms is equal to the growth in centimeters minus one hundred. Modern modified formula Brock looks like this:
- if the increase – up to 165 cm, the ideal weight in kilograms is equal to the growth in centimeters minus one hundred;
- if height – 166-175 cm, the ideal weight in kilograms is equal to the growth in centimeters minus one hundred and five;
- if the growth of more than 175 cm, the ideal weight in kilograms is equal to the growth in centimeters minus one hundred and ten.
Such a calculation of weight is most suitable for people under the age of forty to fifty years. Before that age figure should be reduced (by approximately 10-12%), and after – to increase by about 5-7%. Broca’s index does not account for the constitution, so the correct calculation for hypersthenic and asthenic physique will need to make a recalculation.
Today the standard for calculating the ideal weight is taken account of body mass index (BMI). By BMI revealed a deficit or excess body weight, as well as being diagnosed with obesity to some extent. This figure is often taken into account in the drafting of various agreements on health insurance, at its “wrong” numbers, the price of insurance may increase, as it contributes to the development of various severe metabolic disorders that lead to diseases such as atherosclerosis, coronary heart disease, hypertension a stroke.
BMI – a ratio of weight expressed in kilograms by the square of the height, expressed in meters. The formula for its calculation is as follows:
BMI = m/h2,
where m – mass of the body in kilograms, h – height of the individual in meters.
After determining the indicator to evaluate the table, which also takes into account gender. For example, a BMI less than fifteen shows a significant deficit of weight, from fifteen to twenty – just about the weight deficit, from twenty to twenty-five – that the weight is normal, twenty-five to twenty-seven – about overweight and more than twenty-seven – of obesity, higher rates of obesity suggest (to 29 – I degree, and 34 – II A, 40 – II B, over 40 – III).
But BMI does not account for the constitution, therefore, also requires correction of hyper-and asthenic body type.
There are special tables for determining your ideal weight, which take into account weight, height, age and gender. But they tend to require amendments to the constitution.
Body weight – this is a very important indicator of physical development of man. But he can not be the same for everyone, as it depends on age, body composition and physiological (often inherited) features of an organism, particularly metabolism. The human body changes its properties and settings are also of physical activity and various acute and chronic diseases. All of this contributes, as an increase or decrease in body weight, which can lead to various diseases.
Today found that the desire to have an absolutely ideal weight is not always a positive effect on human health, so little extra weight compared with the ideal much better effect on health.
