Follow the 4:1 rule. No eating, drinking, supplements or exercising for 4 hours prior to the measurement, and no smoking for 1 hour prior. Also make sure that the client has rested for at least 10 minutes prior to beginning the measurement.

The Gem device has been validated in children 7 years of age. In addition, the Gem may not be able to accurately determine RMR in children younger than 7 years due to the specifications of the GEM requiring 500 ml of tidal flow and 72 ml/min of oxygen uptake.

For more than 80 years, health and fitness professionals have relied on equations that estimate RMR using a persons height, weight, age and gender. Such equations have proven inaccurate by nearly 900 calories. With the Gem device, health and fitness professionals can now easily and accurately measure a persons VO2 to determine RMR, providing a precise measurement of the number of calories a person burns each day at rest. The Gem device has been validated against the Douglas Bag technique, the industry standard in analyzing metabolic measurements, and is within 1% accuracy of the Douglas Bag technique for determining RMR.

Metabolism varies from person to person and can change over time. It is determined by many factors including body composition (amount of muscle and fat), weight, age, genetics and gender. Weight loss or a change in body composition can significantly affect RMR.

Typically, ‘empty’ calories generally refer to foods that are high in calories derived from sugar - especially refined sugars and corn syrup. Not only do these foods tend to be high in calories and low in nutritional value, they tend to burn rapidly, causing a spike in blood sugar levels followed by a rapid energy slump.

RMR is influenced by many factors, including age, gender, genetics, hormones, and medications.

RMR accounts for the vast majority of an individual’s calorie needs each day - up to 75% of the total.

Meaningful weight loss takes time, and an individual may be getting the wrong message if they are weighing each and every day. True weight loss is most accurately measured if an individual weighs every two weeks. Daily fluctuations in weight are often the results of water weight and dehydration.
