This calculator uses the BMI cut-offs recommended for Indian adults. These are lower than the standard international thresholds because South Asians tend to carry more visceral fat and face a higher risk of diabetes and heart disease at a lower BMI.

BMI is a screening tool, not a diagnosis. Please consult a healthcare professional for personalised advice.

Indian BMI standard

When is medication considered?

Indian guidance uses lower BMI cut-offs than Western guidelines. Anti-obesity medication, including GLP-1 receptor agonists, is considered after a structured lifestyle intervention — typically at a BMI of 27–27.5 or above, or from a BMI of 25 when a related condition such as type 2 diabetes, prediabetes, hypertension, dyslipidaemia, NAFLD, OSA or cardiovascular disease is present.

Why is it important to keep your BMI in check?

A higher than healthy BMI can lead to increased risk of the following conditions:

Heart disease

Heart disease is an umbrella term used to describe a variety of conditions that affect the heart. This typically includes narrowed arteries, which can lead to a heart attack.

The risk of developing heart disease is higher for people who are overweight or obese.

Type-2 diabetes

Type-2 diabetes happens either when your body does not produce insulin adequately or cannot utilise it effectively.

The risk of developing Type-2 diabetes is higher for people who are overweight or obese — and South Asians develop it at a lower BMI than other populations.

Hypertension

Hypertension, or high blood pressure, means that your blood is pushing too hard against the artery walls. Over time this can damage both your arteries and your heart.

Being overweight or obese can cause high blood pressure.

Fatty liver

A healthy liver contains only a small amount of fat. However, fat buildup in the liver becomes a concern when it reaches more than 5% of the liver’s weight.

The risk of developing fatty liver disease is higher in people who are overweight or have obesity.
