World Health Organization (WHO) defines overweight and obesity as abnormal or excessive fat accumulation that presents a risk to health.
A simple measure used to classify weight in adults is body mass index (BMI). BMI is defined as a person’s weight in kilograms divided by the square of his height in meters (kg/m2). WHO identifies overweight when BMI is greater than or equal to 25; and obesity when BMI is greater or equal to 30.
In Asians, the cut-offs for overweight (≥23.0kg/m2) and obesity (≥25.0kg/m2) are lower than WHO criteria due to risk factors and morbidities.
