As for the fat/muscle ratio: the measurements were clearly not uniform (different person measuring, or tape/calipers placed is different spots, or subject was "sucking it in" on week 2, etc).     Given the ridiculous numbers posted, combined with the fact that a scam company like Herbalife is highly unlikely to have anybody properly trained in caliper use, it seems all the figures came from the scale and its body composition monitor.  No math needed; it's all bullshit.
