Find Ideal Body Weight (IBW):
Men: 50 kg + 2.3 kg per inch over 5 feet
Women: 45.5 kg + 2.3 kg per inch over 5 feet
Measure Current Weight.
2. Calculate Excess Body Weight:
Excess Body Weight = Current Weight – Ideal Body Weight
Example: A 5’6″ (66 inches) woman weighing 80 kg:
IBW = 59.3 kg
Excess Body Weight = 80 kg – 59.3 kg = 20.7 kg
