Smart scales utilize a technology known as bioelectrical impedance analysis (BIA). Imagine tiny electrical currents traveling through your body – up one leg, across your hips, and down the other.
These currents encounter resistance, and by measuring this resistance, the scale employs a mathematical formula to estimate your body composition. This includes metrics like body fat percentage, water weight, bone density, and muscle mass.

However, a crucial safety note: if you have an implanted medical device or are pregnant, ensure the scale offers a weight-only mode or the ability to disable the electrical current.
