What Is A Body Fat Scale

Today, with more and more advanced technology, when you step on a scale, it can clearly tell you the various health indicators of your body.

In addition to listing your weight, body fat percentage and bone and muscle mass, it can also be synchronized to your phone or computer. 

It is important to master and track this information, which can not only greatly increase your chances of losing weight, but also help you better understand the health of your body.

Today’s guide will introduce the 8 most popular smart body fat scales on the US market.


For people with pacemakers or pregnant women, it is best not to use an electronic body fat scale.

Better yet one should consult a doctor before using it because many of these scales use bioelectrical impedance (BIA) technology to measure body fat.

This means that electromagnetic waves may interfere with the function of pacemakers and may affect pregnant women.

Again, it is best to always consult your physician.

The 8 Best Body Fat Scales Review

1. RENPHO Bluetooth Body Fat Scale

It is one of the best-selling products on Amazon and the most cost-effective body fat scale.

A scale like this can help you monitor your weight loss progress and reach the health goals you set for yourself.

The bottom of the scale is made of ABS hard plastic. The panel is 5 mm thick tempered glass, while there are four high-precision sensors and four high-sensitivity electrodes, which can be automatically calibrated to give you more accurate readings.

This scale also has a Bluetooth function. You can download the free apps provided by RENPHO or other apps you are accustomed to using on the App Store/Google Play and sync them with Samsung Health, Apple Health, Google Fit or Fitbit, to share weight loss progress to family and friends.

When multiple people in your family use the same scale, everyone can store their own information and data separately to avoid confusion. You can also transmit the information to your phone via Bluetooth and the FITINDEX app.

Its panel is made of 5mm tempered glass, and the bottom is made of high-quality ABS plastic. It is also equipped with four high-precision sensors and four electrodes to ensure rapid and accurate analysis of body composition.

This is very convenient to use. You just have to download and install the corresponding app and stand on the scale. Then your body composition information and data will be transmitted to your mobile phone, where you can track or share your weight loss process at any time.

3. Greater Goods Smart Body Fat Scale

From an appearance point of view, the body fat scale from Greater Goods is a bit more fashionable. I like its black panel and light gray streamlined stripes design.

Unlike most other body fat scales, this scale uses a one-to-one storage method to separately and securely synchronize the measurement data of each user. Even when several people use the same scale at the same time, other people will not be able to see your information.

Its tempered glass panel is 15 inches (38 cm) long, so people with larger feet can also use it. The feet of the scale are equipped with non-slip pads to prevent any sliding or scratching of your wooden floor during use.

This scale is applicable to mobile phones like Android5 and above, iPhone 5S and above or any iPad released after 2013.

One disadvantage is that this body fat scale can only measure and analyze 6 indicators, including body weight, BMI, body fat, muscle mass, moisture and bone mass.

4. YUNMAI Premium Body Fat Scale

This body fat scale by YUNMAI is very easy to set up and use. After taking it out of the box and installing the battery, you can download YUNMAI on your phone. Once downloaded, just turn on Bluetooth and follow the steps to connect it.

With this scale, there are two weight units: metric (kg) and imperial (lb).

This scale uses bioelectrical impedance technology to accurately measure body weight, body fat percentage, water percentage, muscle mass, and bone mass.

However, with this scale, the measurable physical indicators are not complete, because it does not measure BMI, which is a pity.

Nonetheless, if your purpose is mainly to use this scale to monitor the progress of your weight loss, rather than your overall health level, then the five basic functions it comes with are sufficient.

A Few Tips For Using The Body Fat Scale Correctly 

  • When using any scale please make sure to place it on a flat, hard surface. Avoid using carpets, foam pads, bath mats, or any other article placed under the scale.
  • If you use a smartphone app, it is best to back up your data. For example, backing up your data to Google Drive or another platform can help prevent the accidental deletion of your data.
  • Try to use the body fat weight scale at the same time every day. This will help to provide relatively more accurate weight or health data and development trends.

Frequently Asked Questions

Q: What is the difference between BMI and body fat percentage?

A: BMI is the abbreviation of “Body Mass Index”, also known as body mass index, which is a common tool for assessing the ratio of weight to height. It mainly measures whether you are overweight from a health perspective. It is used to calculate the risk of chronic diseases caused by your obesity level.

Calculation method: BMI = weight (kg)/ (height [m])2

You can use this free online BMI calculator to calculate your body mass index.

The World Health Organization believes that for people between 18 and 65 years old (except for pregnant women, breastfeeding women, the elderly, and athletic athletes), the following criteria can be used to judge whether a person is too thin or too fat: [*]

  • BMI value lower than 18.5: Underweight
  • BMI between 18.5-24.9: Normal
  • BMI between 25-30: Overweight
  • BMI that is more than 30: Obesity

Body fat percentage(BFP) is the total mass of fat divided by total body mass, multiplied by 100.

Relatively speaking, to judge a person’s true degree of obesity, body fat percentage is more illustrative than BMI. However, it is better to combine the two indicators to be more objective and accurate.

Q: When is the best time to use a body fat scale?

A: It is recommended to use the scale in the morning after going to the bathroom, or two hours after breakfast, to get the most accurate figure.

Try to ensure that you use the scale at the same time every day, to accurately track the trend of weight loss and healthy development.

Q: How do I know which scale is best for me?

A: You can ask yourself a question: What is my purpose for this scale?

  • Some people just want to know whether their weight has gone up or down. In this case, a simple weight scale is enough;
  • Other people want to know about more changes in physical indicators, such as BMI, body fat percentage, muscle mass, metabolic level, bone mass, etc.. This information can help them track and manage their weight more accurately and understand their health more clearly. For these people, a body fat scale will be a much better choice.
  • In addition, those who are technically advanced or people who like to store and/or share their data will be more interested in higher-tech fitness measurement equipment.

Q: What is muscle mass?

A: There are about 650 muscles in the human body, which account for about half of your body’s weight.

According to the difference in structure and function, muscles are divided into three types: skeletal muscle, smooth muscle and cardiac muscle.

  • Skeletal muscle is the power part of your exercise routine. When you increase the muscle strength through exercise, you exercise skeletal muscle.
  • Smooth muscles are present in the digestive system, blood vessels, bladder, respiratory tract and women’s uterus. They are stretched and contracted by the nervous system.
  • Myocardium exists only in the heart.

The quality of each muscle is related to the normal operation of the entire body system.

Q: What is bone mass?

A: Bone mass represents the health of bones. It refers to the content of bone tissue. Bone tissue includes bone minerals (calcium, phosphorus, etc.) and bone matrix (collagen, protein, inorganic salts, etc.).

The strength of human bones is closely related to the amount of bone mass. However, an increase in bone mass cannot be achieved by supplementing calcium alone.

Collagen is also an important component of human bones, especially cartilage tissue. Therefore, it is very important to supplement collagen as well.


Losing weight is not just about weight loss, but more importantly, reducing body fat.

An accurate smart body fat scale can help you comprehensively master various indexes of your body, allowing you to track and manage your weight and health status more easily.
