Step-by-Step Worked Example
Scenario: Male standing 5 ft 10 in tall (10 inches over 5 ft).
- Base weight = 50 kg.
- Additional inches: 10 * 2.3 kg = 23 kg.
- Ideal weight = 50 + 23 = 73 kg (160.9 lbs).
Result: Ideal Weight = 160.9 lbs

No. Bone density, muscle development, and genetic frame size account for significant natural healthy variance of +/- 10% to 15%.
