Your guide to choosing body-fat scales

THE SMART-SCALE GENERATION

• Smart scales connect to your smartphone or tablet, so you can view, store and track your vital statistics through an app. Most of the scales transfer your weight and measurements to an app.

• The scales can be set up only with an app. Download the app before purchasing the scale to determine whether you like it, as some smart scales aren’t compatible with all operating systems.

• Some smart-fitness device manufacturers require you to use the app, scale and a smart device together.

• Key measurements include: BODY-FAT PERCENTAGE: Proportion of body fat to weight. BODY-WATER PERCENTAGE: The total amount of water in your body

expressed as a percentage of your total body weight.

BODY MASS INDEX (BMI): Some scales provide a BMI reading based on your height and weight.

MUSCLE AND BONE MASS: The percentage of your body’s composition that comprises muscle and bone.

VISCERAL FAT: A higher amount is linked to an increased risk of conditions such as type 2 diabetes and heart disease. Some scales include graphs that display how your measurements and weight change.

BUYER’S GUIDE

• DISPLAY: Look for a data display that you’re able to read – some models have a backlight, making it hard to read from standing height.

• CONTROLS: Opt for clearly labelled controls.

• USER PROFILES: If more than one person will be using the scale, choose one that supports multiple user profiles.

• PRICE VS VALUE: Basic scales measure only body-fat percentage, while models with more features provide a full body measurement.

• MULTIPLE MODES: Some scales have different modes that give you target numbers.

• SIZE: A wide platform offers more standing room.

• MODELS: For connected scales, stick with the same brand that can be paired with other fitness devices such as smartwatches or activity trackers.

WEIGHING TIPS

• Stand barefoot for best contact with the scale’s sensor pads. • Wet or moist feet affect the conductivity of the signals and might produce inaccurate results. • Try to measure yourself at the same time of day, under the same conditions. • Don’t stress about daily measurements as your weight fluctuates every day. Weekly averages are more useful. • Put the scale on a hard, level floor. • If you have a pacemaker or are pregnant, check with your doctor before using these scales as the electrical charge could have a negative effect.
