What is a healthy BMI?

A BMI between 18.5 and 24.9 is generally considered healthy for adults. Below 18.5 is underweight, 25–29.9 is overweight, and 30 or above is classified as obesity. These ranges are a guide, but a clinician can give a more complete picture.

BMI is a useful population-level screening tool but has limits for individuals. It doesn't account for muscle mass, bone density, or fat distribution. Athletes may have a high BMI despite low body fat. Use it as a starting point, not a diagnosis.

Can I lose weight if my BMI is in the healthy range?

Yes. BMI doesn't capture all aspects of body composition. If you want to change your weight or body composition, a clinician can assess whether that's appropriate for you and build a safe plan.

Calculate your BMI

Body Mass Index (BMI) uses your height and weight to estimate your weight category. This calculator is for adults aged 20 and over. It does not measure body fat or predict how quickly you can lose weight.

BMI does not measure body composition directly, and it may not accurately reflect the health or wellness of individuals of a specific race/ethnic group, those with high muscle mass, pregnant women, children, the elderly, or those with specific health conditions. BMI should not be used as a sole diagnostic tool. The BMI calculator does not determine eligibility for any weight loss medications or treatments provided via the DarDoc platform. Consultation with a healthcare provider is required to assess suitability for any medical treatment based on individual health and medical history.
