Advanced Body Analysis

Have you ever wondered how many calories you need to lose, gain or maintain weight? Knowing your body composition can help you set goals related to diet and exercise. Or, it can help you track progress for building muscle for your sport of choice.
A baseline test shows how much of your total weight is made up of muscle and bone versus fat. A separate repeat test, performed and interpreted by an experienced exercise physiologist or sports dietitian, can assess if your efforts are resulting in muscle building or changes in your body’s makeup.

Our Advanced Body Analysis Package may include up to three of the following tests:

Indirect Calorimetry

Indirect calorimetry measures the oxygen your body consumes. Using this measurement, it calculates your resting energy expenditure (REE), commonly referred to as a resting metabolic rate (RMR).

During this test you will relax in a comfortable position and breathe normally into a specialized mouthpiece that is connected to the ReeVue machine. After approximately 10 minutes you will know your results!

Here is an example of the information you will learn from indirect Calorimetry: Sample Results Printout

For more information on the ReeVue and RMR, read the “What conditions can it help” section below.

Bioelectrical Impedance

When you stand on the Tanita scale, a very low, safe electrical signal is sent from the scale through your feet to your legs and abdomen.

The electrical signal passes quickly through water that is present in hydrated muscle tissue but meets resistance when it hits fat tissue. This resistance, known as impedance, is measured and is used by the scale to calculate what your body is made of (body composition).

You will not feel anything during this test.

Skinfold Test

An exercise physiologist or dietitian estimates body composition through a three-site caliper test:

  • Men will be measured at the chest, belly and thigh
  • Women will be measured at the tricep, thigh and suprailium (the skin just above the hip)

This test does involve a caliper that pinches skin and can be a bit uncomfortable.


    Knowing body composition and calorie needs can help with weight loss, muscle mass gain or sports performance.

    Indirect Calorimetry/ReeVue:

    • The ReeVue measures number of calories burned at rest.
    • It helps determine daily calorie range needed to lose or maintain weight.
    • It provides a more accurate assessment of calorie needs versus using bioelectrical impedance or a basic equation – it measures YOU since it is not using a formula.
    • ReeVue considers genetics, medications, muscle mass, exercise and hormones and how these factors may affect your metabolism.
    • If having difficulty losing, maintaining or gaining weight, ReeVue helps determine if daily caloric intake may be the cause.
    • It allows your care team to build a more personalized and accurate health plan for improved results.

    Bioelectrical Impedance/Tanita and Skinfold Test:

    • These tests are helpful for studying body composition and comparing body composition changes as weight is lost or muscle is gained.
    • They help in selecting an ideal target weight.
    • Several measurements from different tests can provide more accurate results about your body composition.
    • Skinfold measurements give an alternative for those who cannot complete bioelectrical impedance (Tanita) test.

    Your results will be used to personalize your treatment plan.

    Sports Performance:
    For those interested in sports and exercise performance, your exercise physiologist and dietitian can use this information to tailor your meal plan and training plan to maximize your results, allowing you to work smarter, not harder.

    Weight Management:
    For weight loss, weight gain and weight maintenance, use results to guide a calorie goal and track changes in body composition.

    In many instances, individuals have either been told or they suspect that their metabolisms are “slow” when trying to lose weight. While having a slow metabolism is uncommon, undergoing metabolic testing is an easy way to detect and diagnose this disorder.

    With weight loss, calorie needs change, and plateaus in weight loss can occur. In this instance, it would be an excellent time to reassess RMR and changes in body composition. In maintenance, measuring RMR can be helpful to show the effects of the weight loss treatment, assisting with setting long-term calorie intake goals.

    We will tailor your appointment to your needs. You may choose to have up to three of the tests completed. Your provider may guide you in deciding which test(s) will be most beneficial to you.

    1. Do not drink alcohol 48 hours prior to the test.
    2. Avoid intense exercise 12 hours before the test (running, weight lifting, or any exercise for a duration longer than 30 minutes).
    3. Avoid eating or drinking (especially caffeinated products) 4 hours prior to the test.
    4. Empty bladder 30 minutes prior to the test.
    5. Avoid all diuretics for 7 days before test, if possible. Please consult your primary doctor before stopping any medications.
    6. Avoid using lotion(s) or moisturizers on skin (especially skinfold locations) at least 1 day prior to test.
    7. Wear comfortable clothing, preferably gym clothes such as t-shirt and gym shorts.
