5 ways to measure body fat percentage and why it matters

How to measure body fat percentage

Medical, scientific, or research settings yield the most accurate measures of body fat. However, if staying active and fit is important to you, and you don’t have access to research facilities, you’ll want more achievable ways to measure fat. 

Understanding your body fat percentage can help you live a healthier life. Your sex, age, and body type are all critical factors contributing to your overall body fat and your diet and exercise regimen. Too much or too little body fat can lead to different health issues, so a fuller awareness of what’s happening in that area is important.

For example, many people naturally want to avoid obesity and the health problems it brings. However, where is your body fat being stored? That matters, too. Belly fat can lead to a higher risk of heart and circulatory diseases as well as cancer and diabetes, but not all fat is bad.

What is body fat percentage?

Water, protein, fat, and minerals make up the composition of your body. Fat presents itself in two ways — essential fat and stored fat.

Essential fat lives in your bones, liver, kidneys, intestines, and muscles. This is good fat, and your body needs plenty of it to function normally. ‌

Stored fat is found in your adipose tissue and provides energy for your body. It insulates and cushions your organs and is also found under your skin. Too much stored fat can harm your health and lead to chronic diseases and conditions such as heart failure, diabetes, obesity, and fatigue.

Regularly checking your body composition will help you understand how fat and muscle mass fluctuate. Increasing your exercise routine but your weight stays the same helps you see how your internal body composition has changed and possibly improved.

Why should you trust body fat percentage instead of BMI?

To get a basic idea about how your weight can affect your health, many people use their body mass index (BMI). Many doctors believe BMI is a good tool for determining whether someone is underweight or overweight. 

Unfortunately, your BMI doesn’t take into account your muscle mass. 

Exercise has many benefits and can help you not only lose fat but also gain muscle. Your weight may increase because muscle is denser than fat. So, weighing yourself alone doesn’t tell you the whole story either.

Paying attention to your body fat percentage can help you make better dietary and exercise choices. If the value is higher than it should be, consider seeing your doctor for guidance on how to proceed. Higher or lower than average values can indicate health issues, such as an increased risk of cardiovascular disease.

5 methods for measuring your body fat percentage

Bioelectrical impedance analysis

The rate at which an electrical current travels through your body, or a bioelectrical impedance analysis (BIA), measures your body composition. This is because your adipose tissue, or body fat, causes greater resistance (impedance) than lean mass.

BIA scales can see how your body fat slows the rate at which the current travels. Then, it estimates your body fat percentage using bioelectrical impedance analysis.

Skinfold calipers

Calipers are simple devices that measure the dimensions of an object. Skinfold, or body fat, calipers can accurately measure your body fat percentage to give you a better overall picture of your health.

You measure the thickness of your skin and subcutaneous fat (underneath) within specific points of your body using skinfold calipers. Then, you enter those measurements into a body fat calculator. This allows you to estimate your body fat percentage better. 

This is especially true for people with average or above-average amounts of body fat. For men, that’s 15% or 25% and higher for women. If you have a leaner body type, under 15% for men or 25% for women, you may find that body fat calipers underestimate your body fat percentage. 

DEXA scan

The Dual X-ray Absorptiometry (DEXA) scan tells you a lot about your body type in a way that’s quick and pain-free. Not only will you get an in-depth analysis of your fat tissue and lean mass, but it will also tell you your bone density.

A sleek and unassuming machine, the DEXA scan has an “arm” that reaches out over a table. It has an open design that allows you to comfortably lie down during the test without feeling claustrophobic. 

It sends dual, low-power X-ray beams to accurately and precisely differentiate between your bone mineral, lean mass, and fat mass to give you an accurate picture of your overall body health.

Air displacement plethysmography

An air displacement plethysmograph (ADP) looks futuristic but provides you with data in the here and now. It looks like a human-sized pod, using air displacement to measure your body fat and lean body mass. 

This is extremely helpful for anyone who wants to understand how effective their exercise programs are as well as their diet and overall wellness. If you’re a competitive athlete or involved in a comprehensive weight loss program, this is also helpful information for you to have. 

It’s also fairly simple. You go into the device and sit down on a small molded seat. To get the measurement, you’ll put on a snug-fitting swimsuit and swim cap. This gives the ADP a good reading of the mass of your body. 

A technician sets up the testing device and closes the door. You’ll sit for two 50-second periods. A large window is there so you won’t feel closed in or claustrophobic. This lasts about three minutes, and the results are available immediately. 

Within 10 to 15 minutes, you and your doctor can see detailed information about your body composition, total energy expenditure, and resting metabolic rate.

3D body scan

A 3D body scan captures either the whole or part of your body. You’ll get a highly accurate and detailed picture that you can view on your computer or other digital device. 

A full-picture body scanning helps you understand your body fat percentage chart and body composition. This information can inform overall wellness and weight loss goals more accurately.

Fitness 101: The perfect bench press with fitness expert James McMillian
Adult, Male, Man

Every man has a similar thought when they first get up to go to the gym. We see it in movies. We see it in TV shows. The bench press is the number one representation of strength. When the movies or TV shows want to showcase their character’s strength, they send them to the weight bench with piles of plates on each side of a bar. The result of that is that when we head to the gym, the bench is the first destination. So, we need to make sure every man is armed with the knowledge and confidence. Men have to learn how to do a bench press and how to do it well.

That is why I reached out to one of my favorite fitness experts for our next edition of Fitness 101, James McMillian. As the President and Head Coach of Tone House, New York City’s premier athletic conditioning studio, he’s spent over a decade in the fitness world. From personal training and coaching high-energy group workouts to bringing people together through fitness experiences across the country, he is likely the busiest father and entrepreneur in New York. He is also in better shape than all of the Avengers and dresses better to boot. So, I will let him take the lead on teaching us about the bench press.

Fall back into your routine: Expert helps us reset after losing an hour of daylight
Dr. Bonnie Mitchell

I went to bed on Saturday night and it was still fall. When I woke up on Sunday, it felt like the winter was barrelling toward me because it was going to get dark before dinner and I was waking up an hour earlier than I am used to. Daylight Savings Time (whether you like it or not) is one of the parts of our yearly life we have to deal with. Once during the year we spring forward and we lose an hour of sleep. The other time of the year, like this past weekend, we fall back and gain an hour of sleep. As you can imagine, changing the hours of the day can destory your rythym, and that can throw off your routine and cause you to fall into a slump. If this sounds like you, I got some help from Dr. Bonnie Mitchell, Clinical Director at The Mental Health and Stabilization Center of Sacramento to get me back on track.

Here is what she sent me and what can help you too.

Not your average wellness gifts: A holiday guide for the health-conscious
Sharper Image

The words “health & wellness” have many different definitions and interpretations—depending on who you ask. As someone who prioritizes health as much as possible in my personal life, I’m painfully aware that this industry is full of endless products that don’t always live up to their claims. When it’s time to go holiday shopping for that “health-conscious” person in your life, I urge you to consider whether they really need yet another protein shaker bottle, reusable gym water bottle, or pack of protein bars.

While there’s nothing wrong with these so-called “gym bro” health & wellness gifts, 2026 is the time to think outside of the box for holiday gift-giving. With an ever-changing selection of modern technology and innovative products available to help inform smart health choices and advance our health, gift-giving in 2026 requires even more thought and careful gift selection.
