Automatic Calculating of Zone Protein Requirements

For the program I am currently working on (W/F/S), I am wondering if automatic calculation of protein requirements would be something people would be interested in when using diet tracking software. If automatic calculation is allowed, I'd add in a way to override requirements if for some reason a workout isn't logged or whatnot.

The biggest problem with the formula is the way lean body mass is calculated. On the zone website (W/F/S), it uses for men: weight, height, wrist and waist measurements, and for women: weight, height, hips and abdomen measurements.

Short of everyone getting DEXA scans done, is there a better way (read: more accurate / less costly) for calculating lean body mass?

Protein = LeanBodyMass * ActivityFactor

Taken from the source on the Zone Living website, activity factors are as follows:
  • Sedentary - 0.5
  • Light - 0.6
  • Moderate 0.7
  • Active - 0.8
  • Very Active - 0.9
  • Elite Athelete - 1.0

Thanks.
