While you are in the program, you have the option of having a body composition test 20-30 pounds before your goal weight or per the doctor’s recommendation. This sheet describes the purpose of the test, how it is performed and how to use the results.

What will the body composition test tell me? Your body composition test will tell you what percentage of your body is fat. Percentage body fat is based on the amount of fat weight you are carrying in comparison to your total body weight. The rest of your body is lean mass, which is the weight of components such as muscle, bone, organs, etc. Lean mass represents a key determinant of the magnitude of one’s resting metabolic rate (RMR). A decrease in lean mass will slow one’s RMR, which could hinder the progress of weight loss. Goals for weight loss and target body weight should be to lose body fat without losing lean mass.

In addition to using the body mass index (BMI) to determine a healthy weight, body composition can be just as important. Sometimes your original goal weight may change after having your body composition measured.

How should I prepare for the test? Please follow these instructions in preparation for your body composition test:

  • No exercise on the day of the test.
  • Bring (or wear) shorts and T-shirt. No pantyhose or girdles. Tank top for females.
  • No food or fluids for two hours prior to the test.
  • Empty your bladder prior to the test.

When do I get the results? Our staff will review the results with you after the test. The entire test and reviewing the results takes about 30 minutes. You will receive a copy of the results; the original is filed in your chart.
