# How to determine the degree of obesity

Instruction

The simplest way to determine the presence of excess weight is the formula "height" (in cm) minus 100. If the number of kilograms does not exceed the resulting figure - there is no excess weight. However, for a more accurate calculation, the following amendment should be applied: for people 155-165 cm tall, the formula is the same as above; for those whose height is from 165 to 175 cm, you need to subtract 105; for those who are above 175 cm subtracted 110.

Determining the presence of excess weight using the above method is very approximate. A more accurate and scientifically sound indicator is body mass index. Calculate it is easy - you need to divide body weight to kilograms by height in meters, squared: BMI = weight / (height) ^ 2.

Now, referring to the following indicators, you need to find out whether there is excess weight. If the BMI is less than 15, there is a strong lack of weight; A BMI between 15 and 19 indicates that body weight is insufficient; BMI from 19 to 25 - weight is normal; BMI 25-30 - body weight exceeds the norm, BMI 30-35 - first degree obesity; BMI 35-40 - second degree obesity; BMI - 40-50 - third degree obesity; BMI over 50 - supercooling.

There is also another indicator of excess weight - the so-called abdominal index. To determine it, you just need to measure the volumes of the waist and hips, and then find the ratio of these volumes: AI = OT in cm / ABOUT in cm).
