Resting Metabolic Rate Testing in Bariatric Surgery Patients

The ReeVue Indirect Calorimeter will be used in this study to measure the resting metabolic rate. The test takes approximately ten minutes to complete. The subject should prepare for the test by avoiding stimulants and exercise on the day of the test, as well as eating meals four hours before the test. The subject will be seated during the test. They will be given a nose clip that looks like a clothes pin to be placed on their nose. A plastic mouth piece that allows all of the air they breathe to come in through the top of the mouth piece and the air they breathe out to go into the ReeVue Calorimeter will also be provided. The subject will remain in this position for ten minutes until the testing is complete.
