Weighing yourself on a weekly basis is one of the most important parts of a diet and exercise program. A daily or weekly weigh-in can keep you focused and moving toward your goals, and you’ll have the added motivation of seeing your weight drop on the scale over the weeks, months, and years. The only problem with weighing yourself weekly on a traditional scale is that you only see a number on a scale, and when you only look at your weight you don’t get a look at the bigger picture of your overall health. Smart scales are one of the recent additions to the connected health technologies available to make staying healthy easier to accomplish.

With a smart scale, you’ll see that your body weight is just one part of the puzzle when it comes to your health. Smart scales can measure a range of health indicators like body fat, body mass index (BMI), standing heart rate, bone mass, and more.

What is a smart scale?

A smart scale is a bathroom scale that looks just like a traditional scale but connects and communicates data with other devices. The main difference between a traditional scale and a smart scale is that the smart scale compiles more than just one metric of your overall health, and shares that data so you can easily store it for future reference. Some are able to capture data like heart rate, bone density, and body mass index then transmit that data to your phone or tablet so you can see a history of your overall progress. Additionally, many work in synch with fitness trackers and multiple health applications, thereby offering additional functionality and benefits.

Technology built into smart scales

A smart scale has built-in technologies designed to collect data from whoever steps on them. This type of scale uses bioelectric impedance analysis (BIA) to obtain your measurements. BIA involves the passing of a very weak, undetectable electrical current up through your feet. The results are consistent and accurate, and they will give you a picture of the state of your body on your weigh-in day.

Smart scales typically communicate with other devices via Wi-Fi and Bluetooth. For example, once you’ve connected your scale to your home’s Wi-Fi, it will use your home network to transmit data to your phone.

All of your data will be logged in the smart scale’s compatible app, and you can share that data with friends and family, share it with health care professional for enhanced health care, or sync it with your favourite compatible fitness apps. If you’re currently using a fitness tracker and app to track your health and fitness data, you may want to choose a smart scale made by the same manufacturer. That way you can ensure complete compatibility between your favourite app and your scale.

Powering a smart scale

In general, a smart scale uses batteries for power. Most smart scales will use AAA batteries, but others will use lithium-ion batteries for extended power. Battery life will depend on how often you step on the scale.

What do smart scales measure?

Stepping on a smart scale will tell you your weight, but it can also go beyond what you currently weigh and show you a more complete picture of your overall health. There are several different metrics smart scales will measure for you.

Body fat

Your body is made up of muscle and fat, and when your weight drops, it isn’t always your body fat that you’re losing. A smart scale will let you know what your body fat index currently is, and it will track your BMI over time so you can find out if you’re actually losing fat when you could be losing water weight or muscle mass.

Body Mass Index (BMI)

Your Body Mass Index is a good indicator of how healthy you currently are by incorporating height and weight into a summary number that categories people as underweight, overweight, etc. A high BMI (usually above 24.9) may mean you have significant body fat, and it’s a good metric to keep an eye on even if you’re not dieting or on an exercise program. Because your weight and BMI increase with unhealthy lifestyle choices, a high BMI may indicate health problems in the future.


Muscle mass

If you’re working out every week and you’re trying to increase your overall strength, you’re probably trying to lose weight too. When you step on a traditional scale and see that your weight has increased, your first reaction might be to worry you haven’t been working out enough. With a smart scale, you’ll be able to see if your weight has increased due to muscle mass acquired during your strength training workouts.

Bone mass

Smart scales can measure your bone mass. A low bone mass could indicate you are at risk for osteoporosis. With your bone mass measurement you’ll be able to know if you should adjust your diet, exercise, or take vitamins to prevent further bone loss or slow the likelihood of future problems stemming from bone loss.

Hydration level

The amount of water you retain can affect the number you see on the scale, so knowing your hydration level is important when weighing yourself. Your hydration level can also let you know if you’re dehydrated and need to drink more fluids.

Heart rate

Knowing how hard your heart beats at rest is just as important as knowing how hard it beats during exercise. A smart scale can obtain your heart rate when you’re stepping on the scale, and tracking it over time can be a good indicator of your overall heart health.

Maximum weight capacity of a smart scale

A smart scale is similar to a traditional scale in that it has a maximum weight capacity. For most smart scales, that capacity is 400 lbs. Some scales may have a lower capacity of approximately 330 lbs. If you’re interested in knowing the maximum capacity of the scale, take a look at the manufacturer’s features prior to choosing your scale.

How many people will be using the scale?

Having a smart scale means you can share your weight and other data with your friends and family, but you can also share the scale itself. You can set up multiple profiles within the compatible smart scale app, and whenever your family members step on the scale they will receive their own health data and have it assigned to their profile. Some scales even have a “baby mode” or “pregnancy mode” to differentiate readings for new moms.

Along with diet, exercise, and a fitness tracker to keep you motivated, a smart scale can be a valuable tool for anyone who wants to see a complete picture of their overall health.
