Ideal body weight (IBW) formulas were designed for medicine doses, not as a target, and they ignore frame size and muscle. Use them alongside the healthy BMI range.
Keep your waist under half your height: under 93 cm (36.5 inches) at 6'1". Waist-to-height ratio predicts heart and diabetes risk better than BMI alone, especially for South Asian adults.
| Waist-to-height | Waist at 6'1" | Meaning |
|---|---|---|
| Under 0.4 | under 74 cm | May be too slim |
| 0.4 – 0.49 | 74–91 cm | Healthy |
| 0.5 – 0.59 | 93–109 cm | Increased risk |
| 0.6 or more | 111 cm or more | High risk |
