For determination of ideal weight use various formulas of calculation: Lorentz's formula, Broca's formula, formula Kyyutla, calculation of the index of the central obesity, calculation of the index of volume of the body. Certainly, each of them has advantages and shortcomings. The formula Kyyutla is the most used, it is caused by its quite high precision and convenience at independent calculation.
It is required to you
- scales for measurement of weight of the person, centimeter.
Instruction
1. Measure the growth, express it in meters.
2. Measure the mass of the body, express it in kilograms.
3. Divide weight into growth squared. Thus you receive BMI (body mass index).
4. If your BMI lies in the range from 18.5 to 25, so you have healthy weight. Bigger BMI, than 25, demonstrates surplus of body weight. If BMI less than 18.5, your weight is insufficiently high.
5. Thus, the maximum body weight which will be considered as healthy for your growth, will be determined by formula m=25*L^2 where L^2 – your growth in meters squared. The minimum body weight which will be considered as healthy for your growth, will be determined by formula m=18.5*L^2. If you don't want to make calculation independently, you will be able easily to find in the Internet.
6. Also, it is possible to find calculators for Broca's formula and Lorentz's formula in the Internet.
