Body mass index (BMI) and waist circumference are the two most common ways to determine if your weight falls in the healthy range. BMI is a reflection of overall body fat content, and waist circumference reflects the fat around the waist.
The fat accumulated around the waist is associated with insulin resistance and so indicates an increased risk of developing diabetes. In addition, excess amount of fat around the waist may increase the risk of high blood pressure, high cholesterol levels, high triglyceride level and heart attack.
The waist circumference of Asian male and female should be smaller than or equal to 90 cm (36 inches) and 80 cm (32 inches) respectively.
