Here are the top 5 ways to measure your body toàn thân fat percentage
We previously discussed the DEXA scan, the BOD POD test, Ideal body toàn thân
fat percentage ranges, and How to get rid of belly fat, buthow do you actually measure body toàn thân fat percentage?
You might be weighing yourself once a month, once a week or even every day. You might also be calculating your
body toàn thân mass index (BMI) every now and then. But what if the extra weight you see on the scale was mostly muscle?
If you have a low body toàn thân fat percentage, a heavy muscle mass and strong bones, you might be wrongly classified as overweight, because your BMI (and weight) would be high. A good way to know is to measure your body toàn thân fat percentage, fat mass and fat-không lấy phí mass.
Similarly, you could have a perfectly “healthy” BMI, you might still have a high body toàn thân fat percentage, and a high amount of visceral fat—the fat that is stored within the abdominal cavity.
Knowing your what percentage of your weight is fat mass and fat-không lấy phí mass will give you a more
accurate view of your health. Thus, maintaining a healthy body toàn thân composition is crucial to prevent disease. Moreover, if you know your fat mass and fat-không lấy phí mass, you could easily plan your exercise and nutrition routine. So learning about body toàn thân composition is also key for optimal performance and appearance.
Fortunately there are several techniques you could use to measure body toàn thân composition. They all have advantages and disadvantages. Some of them are also a lot more accurate than
others. Here are the top five techniques for measuring body toàn thân composition (from the most accurate to least accurate):
1. DEXA / DXA SCAN
Advantages: The most precise and comprehensive method (it provides regional body toàn thân fat data); very repeatable. By utilizing your body toàn thân fat percentage score, you can compare your scans over time.
Disadvantages:
Hard to find. However, Fitnescity now has the largest network of DEXA body toàn thân composition providers in the nation. Find a DEXA scan near you.
DEXA / DXA Scan is widely considered as one of the most accurate and comprehensive body toàn thân composition tests. The DEXA scan utilizes dual-energy X-ray absorptiometry (DXA). The test looks beyond your weight and the traditional body toàn thân mass index (BMI). It determines your total body toàn thân fat percentage, total fat mass and fat-không lấy phí mass. Most importantly, DEXA body toàn thân composition technology provides
regional body toàn thân fat results (trunk, arms, legs, pelvis and android/gynoid regions). A DEXA scan can also measure visceral fat / abdominal fat, which is often associated with increased risk for cardiovascular disease and type 2 diabetes. DEXA results often include bone density as well (bone mineral density – BMD).
Recommended attire: Comfortable clothing.
Test
protocol: Arrive metal/ hard plastic không lấy phí or ready to change. This includes: No zippers, buttons, reflective materials, jewelry or watches, and no bras with clasps or underwire. No metal or hard plastic hair clips or pins. If you have metal in your body toàn thân (such as a replaced joint or a pin in a bone), you should inform the technician.
Comment: You should also note that the scan will subject you to a small dose of radiation, equivalent to that of flying by airplane from
Tp New York to California.

2. BOD POD
Advantages: The world’s gold standard for fast, accurate and safe body toàn thân fat assessment.
Disadvantages: Hard to find. Fitnescity
has a growing network of BOD POD partners across the country. Locate a BOD POD near you.
Based on Air Displacement Plethysmography, the BOD POD uses whole body toàn thân densitometric principles to determine body toàn thân composition (Fat and Fat-Free Mass),
guaranteeing high accuracy and excellent test-to-test repeatability.
The BOD POD’s air displacement plethysmography eliminates the invasiveness of Dual Energy X-Ray Absorptiometry (DEXA) and is therefore suitable for frequent, longitudinal tracking of body toàn thân composition and metabolic changes over time.
Recommended attire: Tight-fitting clothing or bathing suit. Swim cap (you will stay dry).
Test protocol: Two-hour fast prior to the test. No coffee of
alcohol four hours before.

3.Underwater / Hydrostatic Weighing
Advantages: Very accurate.
Disadvantages: Hard to find; you will get wet sitting submerged
completely underwater.
Hydrostatic weighing, or underwater weighing, compares your normal body toàn thân weight (outside the water) to your body toàn thân weight while completely submerged in the water. Using these two numbers and the density of the water, operators can accurately determine body toàn thân volume and density, along with the breakdown of fat mass vs. fat-không lấy phí mass.
Hydrostatic Weighing takes about 30 minutes.
Recommended attire: Minimal clothing.
Protocol:
You must remain motionless underwater while the underwater weight is recorded. The procedure is repeated several times to get a dependable underwater weight measure.
4. Skinfold Calipers
Advantages: Reasonably accurate; affordable; easy to find.
Disadvantages: Margin for error can vary depending on the experience and knowledge of the technician; you can feel
uncomfortable and cold.
This is one of the most accessible methods for measuring body toàn thân composition. The skinfold assessment measures the thicknesses of skin and the subcutaneous fat four to six locations in the body toàn thân. This includes the triceps, shoulder blade, love handle area, abdomen and calves. The Skinfold should not include muscle and fascia in order to ensure accuracy.
Once the test is completed, the measurements are put into a formula for the practitioner to estimate body toàn thân
composition.
The Skinfold Assessment takes about 15 minutes.
Recommended attire: Short sleeve shirts and shorts.
Protocol: It is important to keep holding firmly the fold of skin with the fingers so that the calipers are measuring just the thickness of the skin fold. You should also remain still.
5. Bio-Impedence (scales)
Advantages:
Somewhat affordable; quick and easy to do.
Disadvantages: According to an ABC investigation, body toàn thân fat readings with a scale can be highly inaccurate, mostly because they are sensitive to factors such as hydration, skin temperature, meal time and exercise.
Bio-impedence involves standing on a scale, and in some cases pushing the buttons
of two electrodes that are placed in your hands. A low level (and imperceptible) electrical current is then sent through the body toàn thân. Tissues that contain fluid and electrolytes, such as blood, have high conductivity, while fat and bone slow the signal down. As Bio-impedence determines the resistance to the current as it passes through the body toàn thân, it provides estimates of body toàn thân water and body toàn thân fat.
A Bio-impedence test takes about two minutes.
Recommended attire: Light clothing
and bare feet.
Protocol: You should stand still and quiet while standing and/or holding the apparatus.
Bonus: Online Body Fat Percentage Calculator
The Fitnescity trực tuyến Body Fat Calculator can be used to estimate your total body toàn thân fat based on specific body toàn thân
measurements. The result might not be accurate as the one you would get from an actual body toàn thân composition test, but it can give you an estimate.
To get the best results, measure to the nearest 1/4 inch (0.5 cm).
