WHAT IS OBESITY AND BODY MASS INDEX?
The World Health Organization defines obesity as abnormal or excessive fat accumulation presenting a health risk. To establish specific measures to catalog individuals, calculation of body mass index (BMI in English) is required. For this a calculation of weight in kilograms to height in meters squared is used. It considers overweight individuals to have a BMI greater or equal to 25 kilograms per square meter (kg/m2) and obesity as when it is above 30 kg/m2. Also defined as an excess of 20 percent of the ideal weight, and an increase of 45.36 kg or 100 pounds of weight.
Morbid obesity (severe) is defined by taking the conclusions of the meeting of the National Institutes of Health in 1991, in which the concept was established for individuals whose BMI is greater than 40 kg/m2 or 35 kg / m2 in the presence of high-risk comorbidity, directly or indirectly associated with excess weight.
