metabolic assessment

"Estimated energy needs should be based on resting metabolic rate (RMR). If possible, RMR should be measured."

Position on Weight Management (2009)

Resting metabolic rate (RMR) is the rate at which a person burns calories while at rest. Between 70 and 80% of all calories are burned under resting conditions. Knowledge of metabolic rate is vital to nutritional assessment, weight loss planning, and care of various medical conditions.

A simple 10 minute metabolic test accurately pinpoints how many calories a person burns and calculates how many calories should be consumed to maintain, lose, or gain weight.

How is the Metabolic Test Performed:

    • No exercise the day of testing
    • Fast 4 hours prior to appointment o Avoid stimulants, such as caffeine
    • Patient sits or reclines in a comfortable position.
    • The patient breathes into a mouthpiece.
    • A nose clip ensures that all the exhaled air is analyzed.
    • After 8-10 minutes, the device will beep, indicating the test is finished.
    • RMR results are visible on the screen and are printed out to aid in patient education.
