Obesity is simply defined as an excess of body fat. Peripheral (general) obesity is defined by finding a body mass index (BMI) = Wt(kg)/Ht (M2) of 30 and more. According to BMI, there are three grades of obesity, grade I obesity with BMI of 30-35, grade II obesity with BMI of 35-40 and grade III (morbid obesity) with BMI of 40 and more. On the other hand, abdominal (visceral) obesity is commonly assessed by measuring waist circumference (WC). It is usually confirmed with the finding of WC of 102 cm and more in men and 88 cm and more in women although there are population-based variations in these WC limits. Which is more harmful in terms of health complications, peripheral or abdominal obesity?
