body fat
The human body contains essential quantities of fats, which are necessary for obtaining the necessary energy to survive, and to practice various daily activities and activities. There is a noticeable difference in the rates of accumulation of essential fats between women and men. Because of the pregnancy conditions that women go through, in addition to the hormonal changes that they witness during this period, the percentage of basic and necessary fats for women is 10%-16%, while for men it ranges from 3%-5%, and these fats are often found in adipose tissue. Around the abdomen and chest to provide protection for the internal organs of the body, and in many cases the percentage of body fat increases beyond its normal rates, causing body obesity.
Body fat percentage measurement
The percentage of body fat is measured to find out the level of obesity that its owner suffers from. The percentage of body fat is the calculation of the weight of stored fat in the body and dividing it by the total body weight. The tool for determining the percentage of body fat to know the obesity rate is more accurate than other measures of obesity. Because it depends on measuring the amount of fat in the body to determine the level of obesity, unlike other measures that depend on body weight to determine obesity, and these measures ignore the nature of body mass and do not differentiate between the nature of body weight if it is muscle or fat, so the body with muscles appears obese on other measures. due to the high muscle mass.

Techniques for measuring body fat percentage:
- Infrared scale: In this technique, the body was exposed to a group of infrared rays, and while the muscles reflect these rays, the body fat absorbs the infrared rays, thus showing its size and mass in the body.
- Body Density Scale: The average body density scale ranks the most accurate measure in determining body fat percentage, by dividing the total body mass by the total body size, and subjecting the result to a specific equation to obtain the body fat percentage, and one of these equations is the Serre equation (4.50 – p/4.95 ) (100).
- skinfold scale: In this technique, a specialized caliper is used to limit the folds of sagging skin between its openings, with the aim of calculating the volume of the layer of fat accumulated under the skin in those areas. numbers correctly.
