Your Metabolic Fingerprint is a measurement of your body’s unique metabolism.
Just like your fingerprint, your metabolism is unique to you.
Why is my Metabolic Fingerprint so important to my weight management success?
Knowing your Metabolic Fingerprint is the missing piece to the weight management puzzle. With this information, you now have the ability to precisely know how many calories you need to meet your goals and personalize a program tailored to your body’s needs.
How often do I need to get measured?
We have all been there. We get on a program; we are doing great then BOOM! We hit a plateau, get frustrated and lose our motivation. What causes this plateau are changes in your metabolism as your body changes, whether it's by losing weight, gaining muscle mass or aging.
Keeping tabs on your Metabolic Fingerprint is essential to avoid those frustrating plateaus and see results that keep you motivated to go on. We recommend you re-measure every 4-6 weeks if you are on a weight loss plan, and every few months if you are on a maintenance plan. Talk to your measurement professional to determine the best schedule for you.
How do I get my Metabolic Fingerprint?
Enter your zip code in the Find Out Your Metabolic Fingerprint section at the top of the page to locate a measurement facility near you. Then call and make an appointment.
Similar to getting your cholesterol measured, there are measurement conditions that must be met in order to get an accurate result.
To ensure an accurate measurement you must follow these steps prior to your measurement appointment:
No food or drink (except water) for at least 4 hours
No exercise for at least 4 hours
No caffeine for at least 4 hours
No stimulants or supplements for at least 4 hours
No products containing nicotine for at least 1 hour
How does a measurement work?
At your appointment, your health professional will ask you to sit quietly and relax for at least 10 minutes before you begin the measurement. During the measurement you will breathe into a handheld device for 5-10 minutes. When the measurement is complete, your Metabolic Fingerprint will appear on the screen of the device.
What do I do with my number?
The professional that administers your measurement will talk to you about your results and how you can apply your Metabolic Fingerprint to your current program or a program that is right for you. You can also customize your BalanceLog software with your Metabolic Fingerprint for a more accurate determination of your body's needs
