Devine: Men = 50 + 2.3 × (in − 60) kg
Hamwi: Men = 106 + 6 × (in − 60) lbs
Men = 50 + 2.3 × (height in inches − 60); Women = 45.5 + 2.3 × (height − 60). In kg.
No. Ideal weight varies by body frame, muscle mass, bone density, and age. These are estimates.
BMI 18.5–24.9 is considered healthy.
Hamwi rule: Men = 106 lbs for 5 ft + 6 lbs per inch over 5 ft; Women = 100 lbs + 5 lbs per inch over 5 ft.
Traditional formulas don't account for age. After 50, maintaining muscle mass matters more than hitting a weight number.
