The Advanced Body Composition report, available with the Body Logic scan, offers comprehensive measurements of the body, including the precise location of bone, fat, and muscle mass. This document breaks down the data so you can address questions about the report with our staff at the Center. This scan is highly beneficial to patients with metabolic syndrome, PCOS, obesity, anovulation caused by hormone imbalance and for customers who are in a weight loss program, athletes, police and fire dept. personnel.
When looking at the Adipose Indices on the Advanced Body Composition report, keep in mind that the lower the numbers in the AM percentile column, the less fat there is compared to others of the same age. More specifically:
Total Body % Fat: Indicates a client’s fat mass/total mass.
Fat Mass/Height2: This refers to a client’s Fat Mass Index. It is a more accurate measure of obesity than Body Mass Index (BMI) because it calculates the amount of fat a client has relative to their height instead of total weight relative to height. The higher this number, the more fat they have.
Android/Gynoid ratio: This measurement indicates whether a client is an “apple shape” vs. “pear shape,” with “Android” meaning abdomen and “Gynoid” meaning thighs. A value >1 indicates a client is more “apple shaped” which could mean a higher risk for cardiovascular disease, while a value <1 indicates more of a “pear shape”.
% Fat Trunk/% Fat Legs and Trunk/Limb Fat Mass Ratio: While these measurements aren’t vitally important to everyday health monitoring, they demonstrate the distribution of fat in a client’s body and can be used clinically to track lipodystrophy.
EST VAT Mass, Volume, and Area: These are measurements of visceral fat, the “bad fat” around the insides of organs. VAT area (cm2) > 100cm2 has been shown to be associated with an increased risk of metabolic syndrome and coronary heart disease.
When looking at the Lean Indices on the Advanced Body Composition® report, keep in mind that the higher the numbers in the AM percentile column, the more muscle there is compared to others of the same age. More specifically:
Lean/Height2 = Lean Mass Index: Amount of lean mass a client has relative to height. The higher this number, the more muscle they have.
Appen. Lean/Height² (kg/m²): The measurement of functional muscle in a client’s appendices (legs and arms) relative to their height. This value is linked to physical performance and is used clinically to monitor sarcopenia or other muscle disabilities. The higher the number, the more functional muscles a client has.
The Body Logic scan is so accurate that it measures all fat in the body, both essential fat and storage fat. Storage fat is the fat clients want to lose, but humans need a certain amount of fat to survive – this is called “essential fat.” It is found in places like cell membranes, the central nervous system, the heart and lungs, and digestive system. On average, about 4% of body fat in men and 12% body fat in women is considered essential fat.
For Total Body %, use the age matched graph on the top of the Advanced Body Composition report as a reference. If you falls in the dark blue area, that means he/she is leaner than 50% of people their age. If you fall in the light blue area, that means you have more body fat than 50% of people in your age range. The line in the middle is equal to the mean body fat % for your gender.

The Body Logic scan offers comprehensive measurements of the body, including the precise location of bone, fat, and muscle mass. This information can help you and your healthcare provider assess the state of your health and define successful treatment plans and training programs to help you achieve your health goals.

DXA stands for Dual-energy X-ray Absorptiometry. It means two X-ray energies are used to measure the bone mineral and soft tissue inside your body to provide the most accurate body composition assessment.
The Advanced Body Composition report is included with the Body Logic scan. It provides visual images of the body that show the precise location of bone, lean mass and fat mass. The color-coded system makes it easy for athletes and patients to see exactly where they have fat and muscle on their bodies and provides a visual comparison of changes in the body over time. Detailed measurements of the torso, hips, abdomen and both arms and legs accompany the image to give a complete picture of body composition.
The BodyLogic scan can measure as small as 1% changes in muscle and 2% changes in fat.
For optimal results:
The frequency of Body Logic scans is dependent on your circumstances, goals, and program. Work with your Healthcare provider to determine the best scan frequency for you.
The radiation dose received during one Body Logic scan is approximately equivalent to one day of background radiation. Another way to think about the dose is it is less than the radiation dose you receive during a cross-country flight. The dose from a Body Logic scan is much less than a CT scan or a standard X-ray.
