These smart scales all go beyond a typical digital scale offering. Each of them can measure your body composition, weight, and BMI using an electric current that travels through your foot from the sensor of the scale across your pelvis and down to the other leg. It measures how much resistance the current produces and then uses a mathematical formula to estimate how much fat, muscle, and bone make up your entire weight.

Although these features are useful, they are not reliable for the sensing of fat versus lean mass.

All this is to say, don’t get stuck in those matrices. Follow the instructions that come with your smart scale to get the most accurate measurements and data, and if you are concerned about your body fat percentage, body composition, health, or fitness, ask your doctor as appropriate.
