Reach and maintain your ideal healthy body weight with the help of smart scales

Maintaining an optimal body weight is an important part of healthy living and a great new year’s resolution for 2018. To achieve your wellness and body weight goals this year, consider investing in a smart living device such as a smart scale. If you’re not sure which high-tech smart scale to get since there are so many on the market, take a look at this guide and our comparison of four popular smart scales to get you started towards healthy living and wellness.

Benefits of smart scales

Consider the benefits of owning a connected smart scale and the convenience it brings. Instead of having to record your weight manually, smart scales do the job for you and is able to sync with different health apps to track your weight over time. Many of these smart scales go beyond measuring body weight and measure metrics such as body fat percentage, body mass index, muscle mass and bone mass. Measurements are taken through a process called bioelectrical impedance, which is a low and safe electrical current sent through your body when standing on the smart scale. However, for those that are pregnant or have an electrical implant such a pacemaker, it’s not recommended to use a scale with bioelectrical impedance. Another benefit of a Wi-Fi or Bluetooth enabled smart scale is that you can send data directly to your computer or phone so the information can be viewed through specific apps.

How to pick a smart scale

The key to picking the best smart scale for your needs depends on finding out what it does best and how it fits into your lifestyle. What sort of metrics are most important for you? Most people are only concerned about body weight, body fat and BMI but if you are an athlete and require more detailed data, look for metrics such as hydration levels, muscle mass and lean body mass.

Are smart scales accurate?

If you are worried about the accuracy of smart scales, most consumer-grade scales will have some small margin of error, but most report data very close to if not your actual body weight and measurements. Bioelectrical impedance can fluctuate based on different factors such as hydration levels, but this technology is acceptable for determining body composition over an extended period of time. Most smart scales are accurate and consistent and don’t usually fluctuate more than one or two pounds at most.

Using an app with smart scales

Another important factor for choosing your smart scale depends on the app it uses and if it’s compatible to other health apps. Try downloading the app before you buy a smart living device to see how you like it. Some apps allow other scales to be connected while some connect to others like nutritional services. A general recommendation is that if you have an app you use daily, buy the scale that syncs and works well with it. For example, if you own a Fitbit tracker it would be wise to buy the FitBit Aria2.
