Important Note
BMI is a simple way to estimate body fat based on your height and weight. It's a useful starting point, but it doesn't account for muscle mass or bone density. Athletes may have a high BMI but still be in excellent health. Always consult with a doctor for a complete assessment.
What is a Healthy BMI for Pakistani and Indian Adults
For Pakistani and Indian adults, a healthy BMI range is between 18.5 and 22.9. This is significantly lower than the standard WHO threshold of 24.9 used in Western countries. South Asian populations have a higher percentage of body fat and more abdominal fat even at lower weights, which increases the risk of chronic diseases like diabetes and heart disease earlier.
BMI Chart for South Asian Men and Women — Different Standards
| BMI Range (South Asian) | Category | Risk Level |
|---|---|---|
| Below 18.5 | Underweight | Higher Risk |
| 18.5 – 22.9 | Normal Weight | Low Risk |
| 23.0 – 27.4 | Overweight | Increased Risk |
| 27.5 and above | Obese | High Risk |
Why Pakistani and Indian People Get Diabetes at Lower BMI
Research shows that South Asians have a unique "thin-fat" phenotype — meaning they may appear thin but carry high levels of visceral fat around internal organs. This visceral fat is highly active metabolically and causes insulin resistance even at a BMI of 23. This is why the risk of Type 2 diabetes in Pakistan and India starts increasing at much lower weight levels than in Europeans.
Healthy Weight Range by Height for South Asian Adults
To stay in the "Low Risk" category, Pakistani and Indian adults should aim for weights that keep their BMI below 23. For example, a person with a height of 5'6" (168cm) should ideally weigh between 52kg and 65kg. Exceeding 65kg at this height puts you in the"Overweight" category by South Asian standards, significantly increasing metabolic risks.
