Kettering Health’s Metabolic Rate Evaluation uses Basal Metabolic Rate (BMR) testing to give you a personalized picture of how many calories your body burns at rest. Rather than relying on standard formulas, this simple test measures your unique metabolism, so you and your care team can build an exercise and weight-management plan around your body’s actual needs.

What is BMR testing?

Basal Metabolic Rate (BMR) testing measures the number of calories your body needs each day to carry out its most basic functions at rest, including breathing, circulating blood, regulating body temperature, and supporting organ function. Because the test measures your body directly, it gives you a personalized estimate of your energy needs rather than a generic formula or estimate.

What does BMR testing tell me?

BMR testing helps you understand how many calories your body burns at rest. That information can support:

• Weight loss and weight management planning.
• Personalized exercise and fitness goals.
• A better understanding of your metabolism.
• Individualized wellness and fitness plans.

How is the test performed?

BMR testing with the MedGem® device is a simple, noninvasive procedure that takes about 10 minutes. During the test, you will

• Sit comfortably in a quiet, relaxed position.
• Wear a small nose clip that directs all breathing through your mouth.
• Breathe normally through a handheld mouthpiece connected to the MedGem® device.

The device measures the amount of oxygen your body uses at rest, then calculates your resting calorie expenditure—your basal metabolic rate.

How should I prepare?

For the most accurate results, your healthcare provider may recommend that you

• Avoid food and calorie-containing beverages for several hours before testing.
• Avoid exercise before the test.
• Avoid caffeine, nicotine, and other stimulants before testing.
• Arrive rested and comfortable.

What should I expect after the test?

Results are available immediately after testing. Your healthcare provider will review your results with you and discuss how they can support your fitness, exercise, weight-management, or overall health goals.
