Waist size and health risk: what is a healthy waist for Indians?

Many Indians have what looks like a normal body, with slim arms and legs, but a belly that sticks out. Doctors take this pattern seriously. A measuring tape around your waist can tell you more about your risk of diabetes and heart disease than the weighing scale. You can work out your own number with the waist-to-height ratio tool.

Why does waist size matter more than weight?

Body fat is not all the same. Fat under the skin of the hips and thighs is relatively harmless. Fat stored deep inside the belly, around the liver, gut, pancreas and heart, is called visceral fat. It is metabolically active and releases substances that:

• make the body resistant to insulin, raising blood sugar
• increase triglycerides and lower “good” HDL cholesterol
• raise blood pressure
• deposit fat in the liver, causing fatty liver disease
• promote inflammation in blood vessels

Your waist size is a simple, practical estimate of this deep belly fat. Two people with the same weight and BMI can have very different waists, and very different risks. Read more in BMI for Indians.

What is a healthy waist size for Indians?

Indian consensus guidance uses lower waist cut-offs than many Western guidelines, because Indians develop diabetes and heart disease at smaller waist sizes:

	Increased risk
Men	90 cm (about 35.5 inches) or more
Women	80 cm (about 31.5 inches) or more

These cut-offs apply to adults who are not pregnant. The national ICMR-INDIAB survey found that abdominal obesity is very common in India, in both cities and villages, and often more common than obesity measured by BMI.

What is the waist-to-height ratio?

The waist-to-height ratio divides your waist by your height, using the same units. The simple rule is: keep your waist less than half your height. A ratio of 0.5 or more suggests extra belly fat and higher risk.

For example, if you are 160 cm tall, a waist of 80 cm or more gives a ratio of 0.5. A large review of studies found that the waist-to-height ratio was a better screening tool for heart and metabolic risk than waist size or BMI alone, across many populations. One advantage is that it adjusts for height, so the same rule works for shorter and taller people.

You can calculate yours with the waist-to-height ratio tool. The Body Roundness Index is another shape-based measure that uses waist and height.

How do I measure my waist correctly?

Measuring the same way each time matters more than anything else.

1. Stand straight and relaxed, with your feet together, wearing light clothing or none over the belly.
2. Find the lowest rib at your side and the top of your hip bone.
3. Place the tape midway between the lowest rib and the top of the hip bone, all the way around the body.
4. Keep the tape level, snug but not pressing into the skin.
5. Breathe out gently and read the tape at the end of the breath. Do not pull your belly in.
6. Take two readings and use the average.

Use the same spot, the same time of day (ideally the morning, before breakfast) and the same tape whenever you re-measure.

Can my waist be large even if my BMI is normal?

Yes, and this is common in India. A person with a “normal” BMI of 22 can still have a waist above the cut-off. This pattern, sometimes called “normal-weight obesity” or the “thin-fat” body type, still carries a higher risk of diabetes and fatty liver. Newer obesity frameworks, including the 2025 Lancet commission, recommend using a waist measure alongside BMI for exactly this reason. Read what is obesity.

How do I reduce my waist size?

Visceral fat responds well to the basics:

• reducing refined carbohydrates, sugary drinks and fried snacks
• getting enough protein, from dal, curd, paneer, eggs, fish or soya
• regular physical activity, both walking and resistance exercise
• good sleep and less alcohol

Spot exercises like sit-ups do not burn belly fat specifically. Overall fat loss does. Belly fat is often among the first to reduce when you lose weight, which is why the waist can shrink even before the scale moves much.

What should you ask your doctor?

• Is my waist above the healthy range for Indians?
• Should I be tested for diabetes, fatty liver or cholesterol problems?
• Is my belly fat linked to PCOS, sleep apnoea or medicines?
• What is a realistic waist target for me?

If your waist is high and you also have high sugar or blood pressure, an endocrinologist can help. Book a consultation.
