1. Earlier the formula was considered as the most known method of determination of weight of the person: growth minus 100. By this method the sex, age, the structure of body was not considered. Therefore now if it is about people till 30 flyings, it is accepted "growth minus hundred" to reduce by 10% or to subtract from growth 110.
2. For those to whom for 50, it is necessary to subtract 105-107. Sometimes this formula is changed depending on growth: if the person is lower than 165 cm, subtract 100, from 165 to 175 cm - 105, higher than 175 cm - 110. Now also the addition type is considered. For normal type the result remains without changes, for uzkokostny type ─ 10% are subtracted from the received result, for big-boned ─ 10% increase.
3. Other popular method has been offered in the 19th century by Adolphe Quetelet. It consists in the following: weight in kilograms should be divided into growth squared. If the received figure is ranging from 18 up to 25, then body weight can be considered good.
4. Some scientists consider that it is necessary to proceed not from growth and weight, and from fat percent in organism. For this purpose define vertical fold of fat on stomach in 2.5 cm from navel. If thickness of fold is to 2.5 cm, then fat deposits in limits of norm, it is higher than 2.5 cm - surplus. And if thickness of fold is 1-2 cm, weight is normal irrespective of what it. One of the easiest ways of determination of admissible completeness, this measurement of grasp of waist. For women it has to be no more than 80 cm, for men ─ less than 95 cm.
5. It is also necessary to watch the relation of waist and hips. If this relation less than 0.8 for women and no more than 0.9 for men, then weight is considered normal.
