Obesity is defined as BMI more than:
a. "Although not a direct measure of adiposity, the most widely used method to gauge obesity is Body Mass Index (BMI), which is equal to weight/height (in kg/ m2).
b. Other approaches for quantifying obesity include anthropometry (skin fold thickness), densitometry (underwater weighing), CT or MRI and electrical impedance using data from metropolitan life tables, BMIs for the midpoint of all heights and frames among both men and women range from 19 to 26 kg/m, at a similar BMI, women have more body fat than men.
c. Based on unequivocal data of substantial morbidity, a BMI of 30 is most commonly used as a threshold for obesity in both men and women".
