Your guide to choosing the perfect smart scale

THE NEW GENERATION OF SMART SCALES

• Smart scales connect to your smartphone or tablet to enable you to view, store and track your statistics through an app. Almost all transfer your weight and other body measurements to an app (either directly via your Wi-Fi or when connecting to your inproximity device using Bluetooth and/or Wi-Fi).

• This is a convenient way to track your progress but having your device on when you step on the scale might be a nuisance.

• These scales can only be set up using an app so check the device and operatingsystem compatibility. Download the app before purchasing the scale to see how you like it.

• Some smart-fitness device manufacturers, such as Fitbit, Garmin, and Polar, require you to use the app, scale, and a smart device together.

BMI

Many people confuse body-fat percentage with BMI but they're completely different. BMI stands for ‘body-mass index' and it's a numeric expression of the relationship between your height and weight. You calculate your BMI by dividing your weight in kilograms by your height in metres squared.

Here's how BMI values are correlated with body-weight status:

• UNDERWEIGHT: <18.5

• NORMAL WEIGHT: 18.5–24.9

• OVERWEIGHT: 25.0–29.9

• OBESITY: >30.0
