How to Choose the Best BMI Scales

Using the best BMI scale is one way to keep track of your health goals. However, measuring your BMI can sometimes be difficult because the score is affected by other body compositions such as muscle mass, bone mass, and body water percentage, among others.

It is not uncommon to get inaccurate scores of either obese or underweight. As such, the following are some of the essential features to look for in your best BMI scale.

a) Compatibility with fitness apps

The first thing you need from your BMI scale is compatibility with Bluetooth or WiFi, smartphones, and fitness health apps. BMI scores can vary depending on other factors like muscle mass and bone mass, so the only way you may get accurate readings is by measuring body fat many times.

When a BMI scale is compatible with your fitness apps like Google Fit, Fitbit, Samsung Health, and Apple Health, it will send and store personal data every time you measure yourself. With time, you can use this data to understand your BMI scores and set goals to maintain your BMI in the healthy range.

b) Other tracking functions

When you measure BMI, there is a great chance you end up with an incorrect score. It happens because measuring BMI alone does not factor in lean mass and body fat. Therefore, you might have a lean, muscular body with a healthy weight and find your BMI scores high.

Incorrect BMI scores happen because your measuring method uses your height and weight only. As such, when these two factors don't measure up to an expected BMI, you might get the wrong readings.

When buying your best BMI scale, make sure it also comes with other measuring functions. It would be best to particularly look for one that calculates your body weight, body fat, and muscle mass, as these are the main measurements that affect your BMI.

c) Ease of use

When buying a BMI scale, you will find models with different features to improve their ease of use. Consider how easy this scale will be to use on your carpet or bathroom floor.

Different surfaces can affect overall readings to give you inaccurate BMI scores. It would be best to buy a BMI scale that compensates for lost gravity on different surfaces such as carpets or bathroom mats.

Additionally, you can also look for a digital bathroom scale that employs positioning control technology. Most BMI scores come with four sensitive electrodes that guide you when you place your feet for the best results.

d) Weight capacity

If you are buying a BMI scale you can use with other family members, it is best to consider the maximum weight it can support to give accurate readings. Some scales can carry as much as 400lbs and give accurate results.
