Body Mass Index (BMI) is a simple measure using your height and weight to determine if you're at a healthy weight.

Understanding your BMI result
BMI is a useful screening tool but doesn't account for muscle mass, bone density, or body composition. For a complete health assessment, consult with our dietitian.
Understand where you stand on the weight spectrum
Set realistic weight management goals
Monitor changes over time with regular checks
BMI (Body Mass Index) is calculated as weight in kg divided by height in meters squared. It is used worldwide as a screening tool, not a diagnostic tool. The WHO categories are: Underweight (below 18.5), Normal (18.5-24.9), Overweight (25-29.9), and Obese (30+).
However, for Indian/South Asian populations, the risk thresholds are LOWER: the Asian BMI cutoff for overweight is 23 (not 25), and for obesity is 25 (not 30). This is because Indians develop metabolic complications, Type 2 diabetes, insulin resistance, and heart disease, at significantly lower BMI values than Western populations, due to a tendency toward higher visceral (belly) fat at any given weight.
Our calculator uses these Asian-adjusted thresholds for a more accurate health assessment for Indian users. If your BMI falls in the 23-25 range, you are considered overweight by Indian standards even though you'd be "normal" by Western WHO categories.
A muscular person may have an "overweight" BMI with very low body fat. Athletes and people who strength train should use body fat percentage instead.
Belly fat (visceral fat) is far more dangerous than hip/thigh fat. Two people with identical BMI can have very different health risks based on fat distribution.
Older adults naturally lose muscle mass, so a "normal" BMI in a 65-year-old may actually indicate insufficient muscle (sarcopenia). Context matters.
Use BMI alongside waist circumference, blood tests (fasting glucose, lipid profile), and body composition for a complete health assessment.
You may be underweight. Consider our weight gain program for healthy, muscle-focused weight gain with Indian foods.
Healthy range. Focus on maintaining through balanced nutrition. Our calorie calculator can help you find your maintenance calories.
Early intervention is most effective. Even a 3-5% weight loss can significantly reduce metabolic risk. See our weight loss program.
