Body fat scales use a technique called Bioelectrical Impedance Analysis... or BIA for short. Very simply...
A small and completely harmless electrical current is passed through your body. The electrical current passes more quickly through fat free tissue like muscle than it does through fat or bone tissue. So... The amount of resistance to the electrical current relates to how much fat-free mass a person has and their body density. Here's the first challenge
