5 Best Body Fat Scales You Can Try in 2021

Almost everyone has a normal/standard scale at home. As a result, it’s all too simple to rely on how much you weigh as proof that you’re on track (or not) with your fitness objectives. However, the number of pounds that display on a conventional bathroom scale can’t reveal how much of our body is fat rather than muscle. That’s where body fat scales come in handy.

Body fat scales are tools to measure aspects of your body composition,” explains Marvin Singh, MD, precision medicine expert from the Precisione Clinic in greater San Diego. “They commonly use a method called bioelectrical impedance analysis, which basically sends a weak current through your body to determine your body composition.”

In other words, such scales work with the help of sensors underneath your feet that use bioelectrical impedance. A tiny electrical current runs up your leg and across your pelvis to assess the degree of resistance from body fat when you step on the scale.

The scale’s sensors then measure the amount of resistance that the current encounters as it travels back through your other leg.

The scale’s signal can link up to your smartphone or smartwatch, as well as any fitness applications you may have, based on the sort of body fat scale you have.

Body fat scales have exploded in popularity, which means shoppers now have tons of options to choose from. The bad news is….you have tons of options to choose from. Because they can all look very much alike, selecting the best scale can be confusing. So we’ve whittled it down to five can’t-miss picks.

What to Look for in a Body Fat Scale

As you can see, the body fat scales available to consumers have a wide range of capabilities. Many of those are down to personal preference like what kind of power source they use, how big they are, whether the one you like has a Wi-Fi or Bluetooth capability or not. Take stock of what matters to you before making a decision.

However, according to Anel Pla, a certified personal trainer at Simplexity Fitness in New York City, the following are important features:

1. Precision Sensors

The most important feature of a digital body fat scale is that it should be able to give precise readings. This will be heavily influenced by the sensors.

2. Different Measurement and Date Options

Some body fat scales can calculate various aspects of a person’s health, including as visceral fat percentage (fat that hides in the spaces between the abdominal organs, which can cause severe diseases), BMI, bone and muscle mass, water weight and metabolic age, among other things.

It’s also useful if it allows you to keep track of several objectives on a daily, weekly, and monthly basis.

3. Should Be Usable On Carpet (if You Don’t Have Any Hard, Flat Floors)

When placed on carpet or uneven tile, some scales don’t work well.

4. Simple Instructions

They should be simple to comprehend and include clear illustrations and guidance on how to interpret your results.

5. Ample Profiles

There should be enough profiles (saved sets of individual information) for everyone who will use the scale on a regular basis. A “guest” profile might be useful for visitors.

6. Tempered Glass

It resists dampness effectively, which is useful if the scale will be kept in a bathroom.

Tips for Using a Body Fat Scale

Because the results are influenced by external factors and variables that our bodies undergo, body fat scales offer rough approximations. However, they can still be used to track your fat loss achievements.

Here’s a checklist to ensure results are as precise and useful as possible.

  • Make sure your feet are clean and bare so that you can effectively connect with the scale’s sensor pads.
  • Take your weight at the same time of day on the same surface (a hard, level floor, unless your scale is specifically made for accuracy on carpeting.)
  • Don’t eat or drink anything for four hours before the procedure.
  • Make sure to urinate around 30 minutes before taking a reading.
  • Don’t weigh yourself for at least 24 hours after heavy exercise or drinking alcohol, and don’t do so immediately after waking up. The reading will be incorrect if your body’s water content is uneven or unusual.
