Body fat vs. BMI

The Centers for Disease Control and PreventionTrusted Source (CDC) outlines the following BMI recommendations for adults:

Below 18.5Underweight
18.5 – 24.9Normal or healthy weight
25.0 – 29.9Overweight
30.0 and aboveObese

You can use online calculators to determine your BMI, such as this oneTrusted Source from the National Heart, Lung, and Blood Institute.

Body mass index (BMI) is perhaps a more reliable indicator of your overall health instead of counting on a body fat scale alone. While BMI can’t measure fat, it does provide an overall picture of whether you’re in the right weight range for your height and age.

REASONS TO AVOID

-Fairly small platform

Of all the scales we’ve tested, this was the fastest and easiest to set up. Just install the app, enter your name, height and gender, and you’re ready to step aboard and start weighing. It takes mere seconds, and the scale can track up to 16 users (it will identify each person according to their weight and body stats).

The Eufy Smart Scale C1 is the best smart scale you can buy today, and makes tracking your weight and body composition effortless.

Weight and body composition data was in line with that recorded by professional scales at our gym, and results were consistent across multiple weigh-ins.

There’s no Wi-Fi connectivity, which means you’ll need to have your phone within Bluetooth range in order to sync your data, but that’s not a serious hardship – particularly since the scale can store up to 100 readings between syncs if it’s out of range.

This is one of the smallest scales we’ve tested, with a platform measuring 28 x 28cm. That makes it handy for small bathrooms where storage space is at a premium, but if you sometimes struggle with balance then you might find one of the many Withings Body smart scales a better choice,

Garmin Index

The Garmin Connect app (Android and iOS) offers a holistic view of your health, including data and metrics such as your activity level, weight, BMI, body fat percentage and other measurements and data.

The smart scale measures weight, BMI, body fat, body water, muscle mass and bone mass, and it offers accurate charts to track weight loss and other data over a week, a month and a year. It uses four AA batteries, and battery life is up to nine months.

EatSmart Digital Body Fat Scale with Auto Recognition Technology

EatSmart Precision GetFit Digital Body Fat Scale

Buy on AmazonBuy on WalmartPros

  • Precise measurements
  • Displays English and metric units
  • 400-pound weight capacity

Cons

  • Doesn’t store data points
  • Doesn’t measure BMI

This scale uses bioelectric impedance to estimate your body fat percentage, muscle mass, bone mass, and total body water, in addition to measuring body weight in 0.2-pound and 0.1-kilogram increments. It can support up to eight user profiles, but it does not store any scale data for those users.

After you set up your profile with the scale—providing your height, age, gender, activity level, and an initial weigh-in—it automatically recognizes you when you step on in the future.

For ideal results, stand on the scale in bare, dry feet whenever you want a new reading. And remember that people with pacemakers should not use bioelectrical impedance body fat monitors due to the (otherwise harmless) electric current they require to take a measurement.

How to choose the best body fat scale for you

First, consider the metrics of body composition that it measures and determine which are most important to you.

There are several factors that you should consider when picking a body fat scale to fit your needs.

Some of the most common measures include:

  • weight
  • body fat percentage
  • BMI
  • estimated calorie needs
  • resting metabolism
  • bone mass
  • muscle mass
  • body water percentage

If you’re interested in syncing your scale to your favorite health app, you may also want to evaluate whether it connects to WiFi or Bluetooth.

Other key factors to consider include the price, power source, weight capacity, and maximum number of users allowed.

How to measure most accurate body fat percentage without scale?

Aside from BMI, you can ask your health provider about the following methods. While stepping on a scale is perhaps the easiest method of body fat measurement, there are other ways you can determine your body fat percentage.

Waist measurements

One drawback to body fat scales is that they don’t tell you how much fat your body is holding around the waistline, which is considered a risk for:

Measuring your waistline can help complement your body fat scale results.

The National Heart, Lung and Blood InstituteTrusted Source notes that your risk for heart disease and diabetes increases if you are a woman with a waist measurement greater than 35 inches (88.9 cm) or a man with a waist measurement of more than 40 inches (101.6 cm).

Dual-energy x-ray absorptiometry (DEXA) scans

Often used to measure bone mass for osteoporosis diagnoses, DEXA scans are also reliable methods of body fat measurement and can be more reliable than relying on BMI alone.

To get one of these scans, you’ll need to find a center that has the equipment. The scans can be pricey depending on your location and may not be covered by insurance.

Calipers

Often used by fitness professionals, calipers are used to literally pinch your skin folds (usually around the waist or hips) to estimate your body fat.

The accuracy of this method varies. Results may be more or less accurate depending on the expertise of the person taking the measurement.

Handheld fat measurement devices

This body fat measurement test works similar to that of a scale, except it doesn’t measure your weight. There are sensors on either side of the device that measure your body fat as you hold the device in front of you.

Handheld fat measurement devices aren’t as accurate as other methods, but they’re easy to use and relatively inexpensive.

Bod Pod

Available at some fitness centers and medical facilities, a Bod Pod is a device you stand in for a few minutes while it measures your body fat via air displacement plethysmography (ADP).

This method has similar accuracy when compared to underwater testing. However, access to these devices is limited, and testing can be expensive.

Underwater weight (hydrodensitometry) test

This test is based on the buoyancy of your body weight. Fat floats more easily than muscle. Based on your buoyancy and your weight, the person administering the test can calculate your body fat percentage.

Underwater testing is considered to be an accurate tool for measuring body fat. However, it can be difficult to find a center that has the ability to do this type of testing. The test can also be uncomfortable.
