Your body weight is not just one number — it is fat, muscle, water, and bone in different proportions. Body composition is the breakdown of those proportions, and it tells you far more about your health than weight or BMI ever can.
Every body is made up of four major components. Knowing the proportions of each is what we call body composition analysis.
All stored fat — subcutaneous (under skin) and visceral (around organs). Visceral fat is the dangerous type linked to diabetes, heart disease, and metabolic syndrome.
The muscle attached to your bones — what moves you, supports your joints, and burns calories. More muscle means a higher resting metabolism.
About 50-65% of your body. Split into intracellular water (inside cells, marker of cellular health) and extracellular water (in tissues — too much can signal inflammation or organ stress).
The mineral content in your bones — important for skeletal strength, especially in women post-menopause and in elderly populations.
BMI uses only weight and height. It cannot tell muscle from fat — so a 75 kg bodybuilder and a 75 kg sedentary person at the same height score identical BMI. One is fit, one is at risk. Body composition shows the difference.
For Indians specifically, this matters even more. Indians have 2× the visceral fat risk and lower lean mass than Caucasians at the same BMI — the so-called "skinny fat" or "thin-fat Indian" phenotype. BMI completely misses this. Body composition catches it.
Several methods exist — each with different accuracy, cost, and convenience.
| Method | Accuracy | Time | Radiation | India Cost |
|---|---|---|---|---|
| DEXA Scan | Gold standard | 15-20 min | Yes (X-ray) | ₹3,000-₹6,000/scan |
| InBody (Multi-freq BIA) | 98.4% vs DEXA | 15-60 sec | No | ₹500-₹2,000/scan |
| Skinfold Calipers | ±5-8% (operator-dependent) | 10-15 min | No | ₹500/scan |
| Single-Frequency BIA Scale | ±5-10% | 5 sec | No | N/A (₹3-15K device) |
| Hydrostatic / BodPod | High | 20-30 min | No | Rare in India |
For most people, InBody body composition analysis is the practical winner: DEXA-grade accuracy, in 60 seconds, no radiation, available at 1,500+ centres across India.
| Category | Indian Men | Indian Women |
|---|---|---|
| Athletic / Fit | 8-14% body fat | 15-22% body fat |
| Healthy | 15-20% | 23-28% |
| Overweight | 21-25% | 29-34% |
| Obese | >25% | >34% |

Body composition is the breakdown of what your body weight is made of: fat mass, skeletal muscle, total body water, and bone mineral. Two people at the same weight can have very different compositions.
BMI cannot tell muscle from fat. Body composition reveals fat-to-muscle ratio, visceral fat level, and water balance — the actual health picture, not just a number.
Indian men: 15-20% body fat is healthy. Indian women: 23-28% is healthy. See our full ranges by age.
DEXA (gold standard, X-ray, expensive), InBody multi-frequency BIA (98.4% DEXA correlation, 60 sec, no radiation), or simpler methods like calipers and basic BIA scales (less accurate). See accuracy data.
Active fitness/weight management: every 2-4 weeks. Clinical monitoring: as your doctor recommends. Same time of day and prep for reliable trends.
Yes — and this is the key insight. Build 2 kg muscle, lose 2 kg fat: scale and BMI show no change, but body composition shows a major transformation. Only body composition analysis catches this.
