You have to use the scale barefoot and it sends some sort of pulse through your feet. You can't use it if you have a pacemaker and another condition or two. That technology has been around for a while. Women over 60 can have a higher than "normal" BMI and still be considered healthy.
I agree with the last sentence - all this stuff is a motivational tool and a tool to mark progress for healthier living.
And also fun for a gadget girl.
From a March 2014 Article:
Body Fat Scales
Body fat scales use a technology called bioelectrical impedance analysis to measure body fat. A small, unnoticeable electrical current is sent from one foot, up one leg and down the other leg. Fat is a poor conductor of electricity compared to other components of the body such as muscle. The more resistance the electrical current experiences, the higher the fat.
Body Fat Scale Reliablity
A "Consumer Reports" study of body fat scales supports what many health and fitness experts say: that these scales are not as accurate as other body fat measurement methods. One issue is that the current runs from foot to foot and therefore is only measuring fat content in the lower body. The Consumer Report study found that the best scales were accurate up to 80 percent of the time. Further, there was no consistency as to whether or not scales reported a higher or lower body fat content. Because of these widespread inaccuracies, "Consumer Reports" no longer tests body-fat scales. Although the scales aren't always accurate, they can still be a tool to measure progress if you test your fat percentage under the same conditions each time.
