Patient Instructions: Measuring Your Resting Metabolism
The most accurate way to assess your nutritional needs is to measure your resting metabolism or the number of calories you burn each day to maintain your normal body functions (heart rate, breathing, and brain activity).
The following suggestions are recommended to optimize the results of the measurement. Your dietetics professional will advise you if these instructions need to be altered based upon your individual situation:
Do not eat or drink anything (except water) for at least four (4) hours before your measurement.
Do not exercise for 4 hours prior to the measurement.
Do not smoke or use nicotine (e.g., gum, patches) for at least two (2) hours before your appointment.
Continue taking your medications as prescribed by your physician, advising your dietetics professional of each medication and any herbs, vitamins, minerals, or other supplements that you are taking.
Plan to sit quietly for approximately 20 minutes prior to the measurement.
Further information about the equipment being used will be described by your dietetics professional.
Once your measurement is complete, your dietetics professional will interpret and may use the results as part of your nutrition care plan.
