Obesity is prevalent in developed countries. It is a major risk factor attributed to the development of various lifestyle diseases.
Obesity is defined as general obesity where the BMI is higher than 25 for the Asian population and more than 30 for the rest of the population1,2.
WHO criteria (kg/m2)
Criteria for Asian Population (kg/m2)
Obese type 1 (obese)
Obese type 2 (morbidly obese)
Obese type 3 (super obese)
Abdominal obesity also defined as a waist circumference has a close relationship with central body fat accumulation and an increased risk of cardiovascular diseases independent of general obesity3. The high prevalence of abdominal obesity is a striking feature of Asian Indians and all South Asians4. It can occur even in the absence of elevated body mass index (BMI) less than 20 kg/m2. Asian populations have 3% to 5% higher body fat than others at an identical BMI5.
Waist Circumference Ranges:
below 31.5 inches
below 37 inches
31.5 to 35 inches
37 to 40 inches
35 inches or more
40.2 inches or more
Waist circumference is found to be the best measurement of obesity whereas Waist to Hip Ratio(WHR) could be used as an alternative indicator for obesity6.
According to the World Health Organization (WHO), in both men and women, a WHR of 1.0 or higher increases the risk for heart disease and other conditions that are linked to being overweight7.
Waist to Hip Ratio
There are increasing concerns regarding the impact of obesity on BMI and longevity8. Obesity can be prevented or reversed by following a healthy and active lifestyle.
A moderate reduction in weight by 5-10% is associated with meaningful improvements in obesity-related metabolic risk factors9. So a comprehensive dietary approach would help to reduce the weight and prevent obesity-related complications.
