How BMI is calculated
BMI compares your weight to your height squared:
Example: 65 kg at 1.70 m height → 65 ÷ (1.70 × 1.70) = 65 ÷ 2.89 = 22.5 (Normal). WHO categories: below 18.5 underweight, 18.5–24.9 normal, 25–29.9 overweight, 30+ obese. Your healthy weight range is simply BMI 18.5–24.9 multiplied by your height squared.
India-specific: Asian-Indian consensus guidelines (Misra et al.) recommend action from a lower BMI — overweight from 23 and obesity from 27.5 — because Indians tend to carry higher body fat at the same BMI than Europeans.
FAQ
BMI kitna sahi indicator hai?
Useful screening tool, but limited. Muscle weighs more than fat, so athletes can show "overweight" while being healthy, and a normal BMI can hide excess belly fat. For a fuller picture, doctors also check waist circumference, blood pressure and blood tests — BMI alone sab kuch nahi batata.
India ke liye alag cutoff kyun?
Research (ICMR/Misra consensus) shows Asian Indians develop metabolic risk — diabetes, heart disease — at lower BMI levels than Western populations. So overweight is flagged from 23 (not 25) and obesity from 27.5 (not 30).
Kya pregnant women ya bachchon ke liye valid hai?
No. This calculator is for adults 18+. Pregnancy changes weight naturally and children need age-and-gender growth charts (WHO child standards) — adult BMI un par apply nahi hota.
Meri BMI high aa rahi hai, kya karun?
Panic nahi — ek number se diagnosis nahi hota. Diet, sleep, activity level, family history — sab context matter karta hai. Apni BMI report lekar kisi doctor se discuss karein; woh sahi next steps batayenge. This tool gives information only.
