How does this adjusted body weight calculator work?
This is a health tool that works as an ABW calculator determining the adjusted body weight according to the actual weight of the user and the estimated ideal body weight. There are three fields to be completed. First you need to select the gender then to input the weight and height.
For your convenience, the adjusted body weight calculator lets you choose whether you want to use lbs or kg and inches or centimeters. Once you have all the data put in, by simply pressing the Calculate button you will receive the result.
Please note that the AdBW and IBW formulas employed in this case are only available for cases with a height of over 60 inches, equivalent to approximately 153cm.
Ideal body weight formula
This is the IBW formula by Devine 1974 that is still used to calculate medication dosages or nutritional requirements in the case of obese patience but can also offer some reference in regard to the indicated weight.
Male: IBW = 50 kg + 2.3 * (Actual height – 60 in)
Female: IBW = 45.5 kg + 2.3 kg * (Actual height – 60 in)
Adjusted body weight formula
This is the IBW adjusted by a factor, usually 0.4 or 40% and it is used especially in cases where the actual weight is more than 20% of the ideal one. It provides a better insight and can be used to calculate energy requirements in obesity cases. For IBW<< Actual weight we continue by calculating the AdBW according to:
AdBW= IBW + 0.4 * (Actual weight – IBW)
