What's your BMI?
Body Mass Index estimates whether your weight is in a healthy range for your height. It's a starting point, not a diagnosis — Calkut uses it alongside your goal and activity level to set a calorie target that actually fits you.
Health risk rises at a lower BMI for South Asian populations, so this narrows the healthy band to 18.5–23.
Healthy weight for your height
55–74 kg
Your BMI falls within the range associated with the lowest health risk for most adults.
How it's calculated
BMI = weight (kg) ÷ height (m)². In imperial units, that's weight (lb) ÷ height (in)² × 703. For most adults, the World Health Organization classifies a BMI below 18.5 as underweight, 18.5–24.9 as a healthy weight, 25.0–29.9 as overweight, and 30.0 or above as obese.
What the bands mean
BMI is one signal, not the whole picture — it doesn't distinguish muscle from fat. Calkut uses it as a starting point alongside your age, activity and goal to set a target that fits.
Underweight
Below the healthy range for your height. If this wasn't intentional, it's worth a conversation with a clinician.
Healthy weight
Your BMI falls within the range associated with the lowest health risk for most adults.
Overweight
Above the healthy range. A modest, steady deficit is usually the safest way to bring it down.
Obese
Well above the healthy range, where health risk rises sharply. A structured plan and medical input both help here.
Not a diagnosis
BMI is a general screening measure and doesn't account for muscle mass, bone density, age or sex. It is not a diagnostic tool. If you have concerns about your weight or health, speak to a qualified clinician.
