📚 Understanding Ideal Body Weight

What is Ideal Body Weight?

Ideal body weight (IBW) is the weight considered optimal for good health based on height and gender. Unlike BMI which gives a range, IBW formulas give a single target weight. Different formulas give slightly different results — the range across all formulas is a reliable target zone.

Ideal Weight for Indians

Research shows that Indians tend to carry more body fat and visceral fat at the same BMI compared to Western populations. The World Health Organization recommends lower BMI cut-offs for Asians — overweight starts at BMI 23 (vs 25 for Western populations) and obese at BMI 27.5 (vs 30). This means the ideal weight range for Indians is slightly lower than standard Western charts.

❓ FAQs

Q: Is ideal weight the same as healthy weight?
A: Not exactly. Ideal weight formulas give a single number based on height and gender. Healthy weight is a range (typically BMI 18.5–24.9). For Indians, a BMI of 18.5–23 is considered the optimal healthy range. Both are estimates — body composition (muscle vs fat) matters more than weight alone.
Q: Why do different formulas give different results?
A: Each formula was developed for different clinical purposes and validated on different populations. The Devine formula was originally created for medication dosing in clinical settings. The Hamwi formula was developed for diabetes management. The Robinson and Miller formulas are revisions of these. None is definitively "correct" — the average across formulas is a reliable guide.
Q: Should I aim for the exact ideal weight?
A: No — ideal weight is a guideline, not a rigid target. A range of ±5 kg around the calculated ideal is perfectly healthy for most people. Factors like muscle mass, bone density, and body frame size all affect what is healthy for you. Focus on energy levels, fitness, blood markers, and BMI range rather than hitting an exact number.
