How Do Body Fat Scales Work?

Although the scale is a useful tool for measuring weight loss, it is limited to assessing one component: weight. On the other hand, measuring body fat percentage can better gauge the effectiveness of your diet and exercise program.

A body fat scale is a device that a person can use to measure their weight and body composition at home. The term "body composition" refers to the relative percentage of body fat, muscle, and water.

How do they work?

The body fat scale uses a technique called bioelectrical impedance analysis to measure body fat. Basically, you step on a small sensor that sends tiny, unobtrusive electrical currents on one leg and the other, measuring the amount of resistance encountered along the way.

Fat is a poor conductor of electricity compared to other parts of the body, such as muscle. So the idea is that the more resistance the current experiences, the higher the body fat content. Body fat scales can provide a wealth of information including:

  • Metabolic age
  • Basal metabolic rate
  • Bone density
  • Physique rating
  • Muscle quality
  • Muscle mass
  • Body water percentage
  • Visceral fat
  • Body fat percentage

Smart body fat scales like BodyPedia can also connect to your smartphone or tablet, making it easier to access your body data. It also helps you target areas for improvement, train effectively, adjust your diet, set achievable goals, and track body composition over time to achieve success.

How to use body fat scales

As with traditional scales, it is best to measure yourself regularly and record the results rather than rely on one-off or occasional measurements.

  1. Make sure your feet are bare and clean in order to make good contact with the sensor pad of the scale.
  2. Place the scale on a hard, level floor.
  3. Do not take measurements immediately after waking up, after meals, or within 24 hours of excessive exercise or alcohol consumption. The water content in your body may be uneven or atypical, which can make readings unreliable.
  4. Measure yourself at the same time of day under the same conditions.
