Assess your body fat distribution and health risks by comparing your waist circumference to your height.
Enter your height and waist circumference to calculate your health risk ratio.
Your body fat distribution indicates a low risk for metabolic diseases.
Visceral fat (fat stored around your internal organs) acts as an active endocrine organ, releasing inflammatory markers that increase insulin resistance and cardiovascular strain. Keeping your waist under half your height is a universal rule for metabolic health.
Understanding why body fat distribution is critical.
BMI often classifies athletes and muscular individuals as "overweight" because muscle is dense. WHtR ignores total weight and focuses entirely on the abdominal region, giving a clearer picture of fat storage.
"Apple-shaped" bodies store fat centrally and have higher WHtRs and health risks. "Pear-shaped" bodies store fat in the hips and thighs, which is metabolically safer.
Unlike BMI thresholds which should ideally be adjusted by ethnicity and age, the "keep your waist to less than half your height" rule applies effectively across almost all demographics and ages.

BMI cannot distinguish between muscle mass and fat mass, nor does it tell you where fat is stored. WHtR specifically targets abdominal (visceral) fat, which wraps around internal organs and is a major risk factor for heart disease and type 2 diabetes. A muscular athlete might have a high BMI but a healthy WHtR.
Do not measure at your pants belt line. Find the midpoint between the bottom of your ribs and the top of your hip bones (usually just above the belly button). Breathe out naturally and measure without pulling the tape too tight.
A ratio between 0.43 and 0.52 is generally considered healthy for both men and women. A simple rule of thumb to remember is that your waist circumference should be less than half of your height (a ratio of 0.50).

A BMI of 25 is "overweight" for a Western adult, but research shows South Asians carry significantly more body fat at the same BMI — and face higher metabolic risk. The WHO recognises lower BMI thresholds for Asians. Here is what the research says and why it matters.
Most Indians accept an EMI figure from their bank without questioning it. This guide explains exactly how Indian banks calculate EMI — the reducing balance method, how RBI repo rate changes flow through to your loan, and what you can do to pay off your home loan years early.
