On the premise that fat tissue is less metabolically active than is lean
tissue, I use the following method to determine adjusted body weight (abw).
Actual weight minus ideal (or desirable) weight times 25%
Add this number to the ideal (or desirable) weight
Once you have this abw, you may calculate energy requirements as you
normally would, either by using Harris Benedict or any other of the several
The best reference I can put my hands on with short notice is Whitney, et
al. "Understanding Normal and Clinical Nutrition", 4ed. West (1994). page
