Information about BMI can be useful for people who want to reduce their health risks. If a person knows his or her BMI, it is possible to regulate the weight by changing of lifestyle and eating habits.
It is important also to know personal waist circumference, because it indicates the amount of visceral fat that can increase the risk of heart diseases, type 2 diabetes, high blood pressure and some kinds of cancer.
Athletes can be overestimated as overweight because of a large mass of muscles.
The health risk for overweight individuals with a pear shape is lower than for people with apple shape. Visceral fat is more metabolically active than subcutaneous fat and causes a lot of health problems.
If BMI is below 18.5 it is regarded as underweight. If such low index is caused by genetics of a person, then it is a normal thing. People who are too thin in spite of absence of genetic proneness to thin figure, can suffer from eating disorders such as anorexia nervosa and bulimia nervosa that can lead even to death.
Visceral fat is stored around and above the waist or in abdominal area, as write Smolin and Grosvenor in their work and produces dozens of substances that can influence emerging of inflammation and disease (248).
In last decades people eat more and move less that is why obesity rates grow. Fast food industry also contributes to this process by increasing portions of food they serve. Less people cook healthy food at home, people spend more time surfing on the Internet, not on the sport grounds.
Body weight and composition depend on genetics. Scientist J. Friedman (2006) discovered that such substance as leptin regulates our hunger, but there are people whose receptors mutated and are not sensitive to leptin. These people suffer from instant hunger and obesity, also this mutation is transferred to other generations.
