10 Best Body Fat Scales Tested And Fully Reviewed

0

For those those looking to lose weight and build muscle, getting on an ordinary scale is not enough. That’s because all that is presented is overall body weight and not other important information about body composition like body fat, muscle, water and bone mass.  Just because the number of overall weight might go down,  doesn’t mean that there is actual fat loss.

Thanks to technology, there are now smarter options that will present more in-depth body stats. Body fat scales offer consumers a clearer picture of their health and fitness by allowing us to see our body composition percentages to better be able to track and progress goals.

Stepping on a scale—or selecting one—doesn’t have to be scary. To help consumers make the smartest decision, we gathered a lineup of the options that weigh the most in merit.

Main Features
Along with showing the user’s weight, it gives five additional body results including body fat, lean mass, BMI, water weight, and bone mass, giving an overall look at their overall health with of an impressive accuracy within 0.2 lbs. Up to eight users can track their weight loss progress with results staying separate. With a stylish design its glass can withstand without breaking. Just step on its non-slip surface that is also scratch-resistant. The full results are displayed on a blacklit LCD screen.

Technology / Connectivity
Along with storing the results on the scale, it also uses Bluetooth Smart / LE technology to send data directly to the accompanying free app for iOS and Android, which can be shared to other fitness apps. The scale runs on four AAA batteries, which are included, and comes with a link to instructions for easy set-up.

What Makes It Stand Out
This body fat scale is similar to the Fitbit Aria, but is half its price. The smartphone does need to be in range, but the user doesn’t need to have their device on them to view results. This body fat scale also syncs data separately via 1:1 pairing so it is secure and kept private.

There is a team for tech support to be able to assist if and when a problem arises like when connecting to Bluetooth, and comes with a 5-year guarantee. The company also donates a portion to the Love146 charity to help end child trafficking and give support to survivors, making this the best choice for those looking to make an impact on their lives and on others.

The Criteria We Used To Find The Best Body Fat Scales

The body scales selected on this list were not chosen based on their brand popularity or if they are the latest models to hit shelves. Instead, we conducted in-depth research to determine the best options that are on the market that perform up to the best standards. To find the best scales, we made sure they deliver accurate body composition stats, while also being user friendly. Each of the key factors in creating our list of the Best Body Fat Scales is explained below.

Features
Besides providing overall weight and body fat percentage, what other body composition metrics does this scale measure? Customers may also want to see insights to other aspects of their health, and other indicators like BMI can help them know where they are at and where they need improvement.  How does this scale work, and how reliable and consistent is the data? Will it provide stats for more than one user?

Connectivity
Is this a “smart” scale? Smart scales require Wi-Fi or Bluetooth in order to work. Does it have an accompanying app, and does it sync with third-party apps including Apple or Google Health? If it’s from a wearable maker, is there seamless integration?

Durability
Up to how many pounds can this scale hold? What is it made from? It’s important that the scale won’t break. How long will its battery last?

Style
Does it have an appealing design? Is it stylish enough to leave out?

Weight
How heavy and thick is this scale? This is important if the consumer wants to be able to move it from the bathroom to their bedroom or workout space.

Other Important Factors To Consider

Using a body fat scale provides users with a more complete look into their health because they will know the percentages of their body composition metrics like overall weight, BMI, muscle and bone mass, water, and more. This better helps them stay accountable on their weight loss journey and track their progress because they know what the breakdown is.

Accuracy
It’s important to consider how accurate this data is. One of the best ways to get a completely accurate body fat reading is by using a Bod Pod, which precisely measures body density to reveal how much body fat vs. lean body mass is present.

However, many body fat scales uses bioelectrical impedance, which is accurate enough to be able to view trends over time. Bioelectrical impedance measure the resistance of the electrical wave that flows through the body, with the idea that it will move differently through fat.  It can be hard to determine belly fat since the waves are measure in the lower half of the body. Other factors like hydration, the time of day, and even PMS can effect the accuracy of the reading.  Because of the use of bioelectrical impedance technology, many body fat scales are not safe for pregnant women or those with pacemakers.

Body Fat vs. BMI
Although many body fat scales also measure body mass index (BMI), these two metrics are not the same. BMI refers to the measure of body fat based on a person’s weight in relation to their height. Body fat percentage is how much fat is in the body. It’s found by dividing the amount of fat mass by body weight.

Since BMI doesn’t take into account the weight of muscle and bone,  body fat is a much better indicator to finding a healthy weight for each individual.

FAQs

Q: How does the scale measure metrics like body fat, BMI, muscle, etc?

A: Many scales use bioelectrical impedance analysis to measure these. A small electrical signal is sent through the legs. The speed of the signal is then able to detect fat mass, etc. The electrical current moves more quickly through water, more slowly through fat. This combined with the user’s weight, age and other metrics, body composition numbers are made.

Q: How does a scale know which user is weighing in?

A: The accompanying apps typically allow the option to add more than one user. Once the new user sets up their own profile by proving info like their age, gender, approximate weight, fitness level, etc., they can step on and start tracking their stats. Using its sensors and algorithms, it is able to identify which user is on based on their metrics.

Q: What Is Pulse Wave Velocity (PWV)?

A: PWV is the measure at which waves move along the arteries. Accepted medically, it measures how stiff the arteries are, allowing the person insight to their heart health. The higher the PWV reading, the more stiff the arteries are. High blood pressure, high cholesterol and diabetes are all factors that can cause stiff arteries.

Q: How do you set up a body fat scale?

A: Setup varies, but generally users download the accompanying app. Set up the profile and step on to start weighing. Many companies also offer an online setup manual on their websites.

Q: How is body age measured?

A: We all have a chronological age, but body age differs by the level of fitness each individual has. Body age is calculated by comparing  basal metabolic rate (BMR) and body composition to reveal how old the body is.

Q: When is it best to weigh yourself?

A: It’s best to use the scale at the same time each day. Even though body fat percentiles won’t drop drastically, it’s a good idea to step on every day to track trends over time. Mornings are the best to to weigh oneself, or wait two hours after eating a meal.
