Fats
The fat rate in the human body is one of the important criteria that affect the assessment of the level of health and fitness of the human body, fat is an important component of the human body, it is the source of energy in the body, and a layer of insulating body of the degrees of external tractor, and the fat layer protects the body from shocks, Important components in cell wall, fats are essential for the manufacture of some important compounds in the body such as hormones, vitamins, yellow juice, studies have shown that the presence of a large mass of body fat over the normal rate caused many chronic diseases that have health risks Great, so you should maintain a certain level of fat within the normal range
Fat consists of carbon, oxygen and hydrogen. It is made up of three fatty acid molecules with one molecule of glycerol to form the tri-glycerides, the main component of fat in the human body. Each gram of fat provides the body with nine calories, does not dissolve fat in water and dissolves In solutions such as alcohol and ether, the glycerol enters the fat structure but is not considered fat because it dissolves in water.
Calculation of fat in the body
Body weight is calculated by calculation. The best time to calculate this is in the morning; because waist circumference and body weight calculation are accurate after a sufficient period of sleep. This equation does not give accurate estimates of body fat, but helps to know If they lose weight of muscle or body fat.
- Measurement of fat ratio in women = (weight × 732) + 986.8 (waist circumference measurement × 157.1570.0 (measurement of buttocks × 249)
We collect the results we obtained and get the percentage of the body mass of the body, and be (the proportion of body fat = total body weight – muscle mass)
- Calculation of fat in men: BMI = (total body weight × 082.1) + 42.94 (waist circumference x 15. 4).
Weight of body fat = (total body weight – muscle mass).
Body fat percentage = (body fat weight × 100).
The normal fat rate in women is 10 to 12 percent. In men, the normal fat rate is between two and four percent. Fat can be measured by other advanced and more accurate methods. There are some devices that measure fat in certain areas of the body. Is a useful way to estimate body fat content.
