How to Account for Body Water % in Body Fat Testing with a Tanita


#1

I got a new Tanita scale the other day (yes, I know they aren't all that accurate, but mine is actually coming pretty close to the DEXA test I had done recently) and I'm going to use it to get a baseline and then to monitor changes when I cut some weight in June. The model I purchased tests for body water percentage in addition to body fat. The higher the body water percentage, the lower the body fat percentage comes in at.

I'm trying to come up with a formula to account for this variable instead of just eyeballing the numbers. I was thinking I could do the following (total weight - body water weight)*BF% = x. Any math types out there care to help? I'm trying to get a number that I can track for "fat" that removes the body water variation.

Just measure every morning when you wake up at the same time.

Why would you want to track it every day?
