Every once in a while, I'll run across a form that asks for a patient's body fat percentage. At present, I have no way to measure this in the office, so I usually leave it blank. Next time, maybe I'll use this program to calculate it. After all, some experts have suggested that body fat may be a better indicator of overall fitness than body mass index (BMI).
Fat Estimator v1.1 estimates body fat percentage and ideal body weight using a tape-measure method by Covert Bailey. It's freeware.
