BMI kya hota hai?
BMI (Body Mass Index) weight aur height ke ratio se body fat estimate karne ka ek simple tool hai. Formula: weight (kg) / height (m)². Yeh ek screening tool hai — diagnosis nahi.
BMI categories — Indian population ke liye
Indian vs WHO standards
WHO standard BMI 25+ overweight define karta hai. Lekin Indian subcontinent ke logon mein body fat composition alag hoti hai — isliye India mein 23+ overweight aur 27.5+ obese consider kiya jaata hai (WHO/ICMR recommendation).
| BMI Range | WHO Category | Indian Standard |
|---|---|---|
| Below 18.5 | Underweight | Underweight |
| 18.5-22.9 | Normal | Normal |
| 23-24.9 | Overweight (by WHO) | Overweight (Indian) |
| 25-27.4 | Overweight | Obese I (Indian) |
| 27.5+ | Obese | Obese II (Indian) |
BMI ki limitations
- Muscle vs fat distinguish nahi karta — athlete ka BMI "overweight" show ho sakta hai
- Age aur gender factor nahi karta
- Body fat distribution (belly fat vs overall) measure nahi hota
- Waist circumference BMI se better predictor hai heart disease risk ke liye
Healthy BMI ke liye weight kitna hona chahiye?
ToolNinja ka calculator height enter karne par ideal weight range bhi batata hai. Example: 5'6" (168cm) height par Indian standards ke liye 52-65 kg ideal range approximately.
BMI calculator accurate hai?
Screening ke liye useful hai — exact body composition ke liye DEXA scan ya body fat percentage measurement zyada accurate hai. Doctor se proper assessment karwayein agar concerns hain.
