Ideal body weight
Estimated ideal body weight in (kg)
Males: IBW = 106#for the the forst 5 ft + 6# for each inch over 5 feet.
Females: IBW = 100# for the first 5 ft + 5# for each inch over 5 feet.
Ex
5’10” male
106 for the first 5 ft + 6x10 or 60 for the 6 inches – 106+60= 166 IBW
5’4” female
100 for the first 5 ft + 5x4 or 20 for the 4 inches – 100+20 = 120 IBW
% excess calculation is
Current weight – IBW x % expected to lose
Example
5’4” female who weight 320 # having RNY would lose 60% of her excess weight
Current weight 320 – IBW 120 x 60% = 120#
This patient could expect to lose 120# with a goal weight of 200# (320-120)
Hope this helps. Sarah
