Transforming Your Body with a Body Composition Machine

Have you ever stepped on the scale and gained three pounds and not know why? Or weigh the same but had trouble zipping up your jeans?  

Chasing a number on the scale can be a lesson in frustration, this is why knowing your body composition and what you are made up of can be an invaluable tool that can put you back in charge of your health and weight loss goals. 

Unlock Your Body’s Potential By Using a Body Composition Machine 

If you are looking to get into shape and reach your fitness goals, the information from a body composition machine is the key and will help take your nutrition and workout regimes to the next level.  

Knowing your body composition can be incredibly valuable when it comes to creating an effective and personalized fitness routine and diet plan. With the help of a body composition machine, you can get a detailed analysis of your body’s structure and composition.  

In this article, we will look at why knowing your body composition is critical and how a body composition machine will help you transform your body for good.  

What is a Body Composition Machine? 

When it comes to our health, knowledge is power. That’s why you should understand exactly what a body composition machine can do and how it works. A body composition machine is an incredible tool that can measure your body fat percentage, lean mass, muscle mass, and more! Let’s break down what a body composition machine is and how it works.  

Definition of Body Composition 

Before we dive into the specifics of body composition machines, let’s start with the basics. The term “body composition” refers to the ratio of fat to lean tissue in your body. In other words, it measures how much of your weight is made up of fat versus lean muscle mass. This measurement can be an important indicator for overall health and fitness levels because having too much or too little fat can increase your risk for certain conditions like heart disease, high blood sugar or metabolic syndrome.  

Types of Body Composition Machines

There are three main types of body composition machines available on the market today— ADP (Air Displacement Plethysmography) machines, BIA (Bioelectrical Impedance Analysis) machines, and DEXA (Dual Energy X-Ray Absorptiometry) machines. High end BIA machines and ADP machines both can have 95-98% accuracy vs the DEXA machine. 

ADP Machines measure body volume by measuring how much air is displaced when a user steps inside an airtight chamber full of water (known as the Bod Pod (R)). The appointment times tend to be long for the user to change and perform the test.  

BIA machines use thousands of electrical signals to measure your body’s resistance to current passing through your cells. Some of these machines are used in fitness centers and gyms because they are relatively easy to set up and use. More accurate and sophisticated BIA machines are found in hospitals like the Mayo Clinic, Cleveland Clinic, professional sports team facilities, and high end medical and nutrition clinics.  

The DEXA machines use low doses of radiation to measure the amount of fat in your body by scanning different parts of your anatomy using X-rays. Because they require more setup time, these are usually found in hospitals where trained technicians operate them safely.  

How Body Composition Machines Work

Now that you know what types of machines are available, let’s talk about how they work. Both BIA and DEXA machines use sophisticated methods for measuring your body’s fat content as well as muscle mass, bone density, and more.  

BIA machines work by sending small electrical signals through your cells which then measure how quickly that signal moves through them; since fat has higher resistance than muscle tissue does, it takes longer for the signal to move through fatty cells than those that contain mostly lean tissue. DEXA machines use X-ray beams to scan different areas to obtain measurements of where all that extra weight is coming from.  

Understanding Your Body Composition 

What Are the Differences Between Body Weight and Body Composition?

Scale weight and body composition are two different measurements related to a person’s physical health and fitness. 

Scale weight refers to the total weight of a person’s body, which includes their bones, muscles, organs, and fat. It is a simple measurement that can be easily obtained using a bathroom scale. However, scale weight alone is not an accurate measure of someone’s overall health and ideal physique. It does not provide information about the distribution of body mass, and it cannot distinguish between different types of body tissue, such as fat, muscle, and water. 

While scale weight is a simple and easily obtainable measurement, it does not provide a complete picture of a person’s physical health and fitness. Body composition, on the other hand, provides a more accurate assessment of a person’s overall health and when interpreted correctly by a trained healthcare practitioner, can be used to create targeted diet and exercise plans to improve their physical fitness, reduce their risk of health problems and optimize their weight loss goals.  

Why is Body Composition Important to Obtain Optimal Health and Weight Loss?

Measuring body composition is important because it provides a more accurate picture of a person’s overall health and fitness.  

For example, a person with a low-scale weight may appear healthy, but if they have a high percentage of body fat, they may be at risk for health problems such as heart disease, diabetes, inflammation, and other chronic conditions.  

In contrast, a person with a high scale weight who has a high percentage of lean tissue, and a low percentage of body fat may be in excellent physical condition. 

What Are Key Metrics Measured By Body Composition Machines?

Body composition machines measure key metrics including BMI (Body Mass Index) (or Body Mass Index), percent of body fat, visceral fat rating (which measures belly fat), metabolic age (an estimate of how old or young your metabolism is functioning), and lean muscle mass percentage and more. All these measurements are used to create an overall picture of an individual’s health status which can then be used to set personalized goals for diet and exercise plans that will increase overall health and wellness over time.  

Understanding Your Body Composition Results

An Inbody 270, Inbody 570 and  InBody 770 test is a body composition analysis tool that provides information about the various components of your body, such as body fat percentage, lean muscle mass, water distribution, and more. Here are some basic things you need to know to interpret various results.  

Body Composition Analysis 

The test measures your body composition, which includes your body fat percentage, skeletal muscle mass, protein mass, mineral content, and body water percentage. These results can help you understand your overall body composition and identify areas that may need improvement

Muscle Mass 

Provides information about your muscle mass in different regions of your body, including your arms, legs, and trunk. This information can be helpful for athletes, bodybuilders, or anyone looking to increase their muscle mass

Body Fat Percentage

Measures your body fat percentage, which is the percentage of your body weight that is made up of fat. This information can help you track changes in your body fat percentage over time and assess your overall health

Visceral Fat Level 

Provides information about your visceral fat level, which is the fat that surrounds your organs. Elevated levels of visceral fat can be a risk factor for health problems such as heart disease and diabetes

Basal Metabolic Rate

Provides information about your basal metabolic rate, which is the number of calories your body burns at rest. This information can help you understand your overall energy needs and plan your diet accordingly. 


This is the most crucial step. When interpreting your results, it is important to: 

  • Consider your age, gender, height, and weight. You should also compare your results to a reference range based on your age and gender. High end BIA machines have this comparison built in to the results pages.  
  • Get an accurate assessment of your results from a trained and Certified Nutrition and Health Coach.  What you do with the results are as important, if not more so, as the results themselves. 
  • Develop a personalized nutrition, supplement, and workout plan with your health coach based on your results. Track your progress and plan a follow-up measurement and session. Make your efforts count and help you work toward your optimum health goals.  

Overall, an InBody BIA machine test can provide valuable information about your body composition and health. However, it is important to get an accurate and meaningful interpretation of the results to map out an effective nutrition and workout plan.  

From Weight Loss to Muscle Gain: How a Body Composition Machine Can Help

Have you ever wanted to shed a few pounds, but weren’t sure how? Or have you wanted to get toned and build muscle, but did not know where to start?  

A body composition machine can help. It can provide you with the information you need to make informed decisions about weight loss (fat loss) or muscle gain goals. Let’s explore how this technology works and why it is so beneficial for your health journey. 

How A Body Composition Machine Can Assist In Weight Loss

Utilizing a body composition machine can give you an accurate measure of your body fat percentage, extracellular water (or bloat) and muscle mass, which is especially important when trying to lose weight

Having this information allows you to determine how much fat, protein, carbohydrates, and water to target in your nutrition to achieve your desired results. This way, you will not get stuck in losing scale weight alone where you may be unintentionally losing muscle mass, shutting down your metabolism and triggering the yo-yo dieting cascade.  

How A Body Composition Machine Can Assist In Muscle Gain

On the other hand, if your goal is to gain muscle rather than lose weight, a body composition machine can also help with that too.  

By measuring your current muscle mass in relation to the rest of your body fat percentage, you can set realistic goals for yourself based on what you want out of your nutrition, lifestyle and fitness routine. Did you know that sleep also has a profound effect on building muscle mass? More about that later.  

With your body composition information on hand, you will be able to make meaningful changes, and track and measure progress more effectively so that you are one step closer towards achieving those results. 

How To Set Goals Based On Your Body Composition

When using a body composition machine as part of an overall fitness plan, it’s important to set realistic goals for yourself. The data from the machine gives insight into what changes are needed for those goals to become reality – whether that means losing 10 pounds of fat, gaining 5 pounds of muscle mass, or losing inflammation or water mass.  

This information allows your nutrition and health coach to create an individualized nutrition and exercise program tailored specifically towards meeting those objectives.  

Metrics like food calorie and macronutrient goals, and if incorporating cardio workouts like running or HIIT classes along with strength training sessions to target specific muscles groups or regions of the body would be beneficial. Remember, you can’t work out a bad nutrition plan; both sets of goals are important to achieve optimal success. 

Using a Body Composition Machine

3 Top Tips on How to Prepare for a Body Composition Test

Before getting tested with a body composition machine, there are a few things that you can do to ensure that your results are as accurate as possible.  

  1. Make sure you are hydrated the day before and the day of the test AND that your bladder is empty before the test. This means drinking 1/2 your body weight in ounces of water the day before and moderate amounts the day of the test. In addition, avoiding alcohol the night before and coffee the day of the test, both of which can dehydrate you.  
  2. Avoid strenuous exercise or taking hot showers before testing as this can impact your results.  
  3. Try not to drink too much water and empty your bladder 1 hour prior to the test as this can also influence the results.  

What to Expect During a Body Composition Test

A body composition test with a machine usually takes between 5-30 minutes depending on the type of machine used and how long it takes for the technician administering the test to collect all necessary measurements.  

During this time, you will be asked to stand still and stay relaxed with no tension in your body while sensors measure various parts of your body such as fat mass, lean muscle mass and more. It is important for accuracy that these measurements are taken correctly so try not to fidget or move around too much during testing 

How Often to Use a Body Composition Machine

How often you use a body composition machine really depends on how frequently you want information about changes in your body over time.  

If you have specific health goals, it is recommended that you track changes over time and get tested every 2-4 weeks since changes in weight may occur slowly over weeks rather than days.  

However, if you simply want one measurement of your general health, then once every 3-6 months should suffice.  

Comparing Body Composition Machines

How Accurate are Body Composition Machines?

The at home body fat scales are the most inaccurate. Studies show that these scales either overestimated or underestimated body fat percentages. The most accurate readings were off by about 21%, while the least accurate were off by about 34% and highly variable day to day.  

The DXA machine is considered the gold standard for measuring body composition with an accuracy of around +/- 1-2% [[1]].  

The best bioelectrical impedance analyzers,  have an accuracy of around +/- 3-8% for measuring body fat percentage [[2]].  

While both the DXA and BIA machines can estimate body composition, the accuracy of the measurements can vary by manufacturer, model types and are affected by factors such as hydration and recent food intake [[1]] [[2]]. 

Different Brands of Body Composition Machines

There are many different brands of body composition machines available. Some popular at home scales include Withings Body+, Innotech scales, FITINDEX Bluetooth Body Fat Scale, Arboleaf Digital Scales.

FAQs (frequently asked questions)

Is it safe to use a body composition machine?

Using a body composition machine is generally safe if used according to the manufacturer’s instructions. However, people with pacemakers or other electronic implants should avoid certain types of machines, and pregnant women should avoid using them altogether. 

Can a body composition machine measure visceral fat?

Body composition machines, such as bioelectrical impedance analyzers (BIA), can estimate visceral fat levels, but their accuracy can vary. Imaging methods like MRI and CT scans are considered more accurate for measuring visceral fat. 

How do body composition machines work?

Bioelectrical impedance analyzers (BIA) estimate body composition by running a small electrical current through the body, which can estimate quantities of fat mass and fat-free mass based on varying amounts of water content in bodily tissues [1].  

What are the benefits of knowing my body composition?

Knowing your body composition can provide more information than just body weight, including body fat percentage, water weight, bone mass, and basal metabolic rate [2]. This can help with setting goals for improving body composition by decreasing body fat, increasing muscle, or both [3], which can have health benefits such as reducing the risk of chronic diseases and improving overall physical performance [2].  

What is the best body composition machine to use?

There are various body composition machines that use Bioelectric Impedance Analysis (BIA) technology, but the accuracy can vary [2]. Professional BIA’s like the InBody 770 model is a highly rated and accurate BIA machine that provides comprehensive body composition analysis and includes visceral fat level and area [[3]]. However, it is important to note that the best machine for an individual may depend on their specific needs and budget. 

How can a body composition machine help with weight loss?

The result of many diet plans leads to weight loss, however, it may also include a loss in muscle mass, which can shut down your metabolism and lead to yo-yo dieting [[1]]. Setting specific and attainable goals is important for weight loss strategies that protect lean body mass, which is important for overall health [1]. By tracking changes in body composition, with a professional assessment from a health care provider, specific adjustments to diet and exercise routines can be made to ensure that the weight loss is primarily from fat mass and extracellular water or bloat, rather than muscle mass [[2]].
