Frequently Asked Questions about Metabolism

Why should I have my resting metabolic rate (RMR) measured?
Metabolic rate varies from person to person and depends on many factors including:
A study published in the journal Metabolism compared women of the same height, age, and weight and found that their metabolic rates varied by almost 900 calories a day. Everyone has a unique metabolic rate, and the only way to know yours for sure is to have it measured.
Does metabolism change over time?
Metabolism varies from person to person and can change over time.
Your metabolism is determined by:
Weight loss or a change in body composition can also affect your RMR.
If you are losing weight or participating in a fitness program that includes resistance training, we suggest measuring your metabolism every time your weight changes 5 pounds (or 5% of your body mass).
Monitoring your RMR will allow you to adjust your daily calorie targets if your metabolism changes. Losing weight and reducing your calorie intake can reduce your metabolism.
To obtain an accurate resting metabolic rate, the test should be done 2-4 hours after eating or exercise. MedGem can be used at other times of the day, but the RMR will be slightly elevated depending on the amount of activity you have done and when you last ate.
A recent study at the University of Colorado Health Sciences Center found that the average difference between RMR measured in the morning, following an overnight fast, compared to RMR measured in the afternoon (at least four hours after eating) was only 100 calories/day. (Abstract pending publication.)
Using regular metabolic testing, the MultiDisciplinary Team will evaluate your USB-Me program and track daily calories, nutrients, and exercise against your targets.
Using your RMR value along with your goals, the MultiDisciplinary Team will shape a program to help you lose, gain, or maintain your weight. Your program is personalized, continually evaluated, and allows you to track calorie burn and calorie intake to achieve your goals.
Metabolism is the body''s process of combining nutrients with oxygen to release the energy needed for the body to function. Metabolism is the total number of calories a person burns each day and includes RMR, occupational activity, and exercise.
Metabolism varies from person to person and can change over time. Your metabolism is determined by your body composition (amount of muscle and fat), body weight, age, and gender. Learn your unique RMR by having it measured using MedGem. Having your metabolism monitored over time will help you balance the calories you burn with the calories you eat. Weight loss or a change in body composition can lower or raise your RMR.
