What is Obesity?

Obesity is a Latin word and means that who is eating too much.

Obesity is a disease that causes very serious health problems and unfortunately shortens the life span. For obesity classification, many parameters such as laboratory and imaging methods, body fat percentage and the type of fat deposition are used. For the moment, however, the World Health Organization (WHO) uses the body mass index (BMI) calculation for the identification and classification of obesity, and it is almost a common language all over the world. It is a value that everyone can calculate with a simple operation. Individuals with a BMI greater than 30 are considered obese.

In particular, the type of fat deposition in the body, that is the fat around the waist (apple type fatness) and the fat around the hips (pear type fatness), has an important role in defining obesity. Although there is not a clear scientific evidence, there is an opinion that the surplus of fat around the abdomen is accompanied by some disesases such as diabetes and atherosclerosis, which are referred to as the metabolic syndrome, accompanied by fat accumulation not only under the skin but also in the internal organs. In other words, the ratio of waist circumference to hip circumference is important. This value should be below 1. In terms of risk of metabolic syndrome, the waist circumference should be 102 cm in men and 88 cm in women.
