Body Fat Scale



What is a body fat scale? A body fat scale is similar to a regular bathroom scale in that you step on it and it provides a digital reading.  However, in addition to your weight in pounds or Kilogram, a body fat scale also claims to provide your body fat percentage. This can be an interesting number to track, especially for those on a weight loss regime that includes exercising.  It can be frustrating when the number on the scale will not budge while you are dedicated to your exercise and healthy eating plan. 


How do they work?  Body fat scales use Bioelectrical Impedance Analysis (BIA).  A very small, harmless electrical current passes through your body tissues, slower through fat and quicker through muscle. Resistance is what is being measured.  So, actually it is not analyzing your body fat percentage so much as your body density.  The scale then takes this reading and uses a formula to give you a body fat percentage reading.
