A CGM (or continuous glucose monitor) is a device that allows you to view your glucose levels in real time. This data is transmitted from the sensor or transmitter and sent to a receiver or an app (like the Nutrisense app) where you can view glucose readings throughout the day.
From these readings, you can spot trends in your glucose levels and pinpoint the patterns in your lifestyle habits that may affect them.
Why pay attention to your glucose levels? It’s a great way to get a better overall view of how your body functions. It can also help you set new wellness goals, and build healthier, more sustainable lifestyle habits.
Navigating the insights from the CGM data and setting a plan to reach your goals can seem overwhelming. But Nutrisense can help make the most of its benefits, with one-on-one support from an expert nutritionist to help you decode the data and support your wellness goals.

The CGM data chart in your app is automatically updated each time you scan your sensor and shows recent changes in your glucose curve.
This CGM chart allows you to see how your levels fluctuate and the exact glucose score for each meal and activity you log inside the app.
Use a CGM to track
A CGM chart may have different elements depending on your chosen provider. The Nutrisense app displays metrics such as the area under the curve (AUC), delta, time in range, peak, and recovery levels.
*These additional metrics provide valuable information for those who want to optimize their blood sugar levels as part of a healthy lifestyle.
So, how accurate are CGMs? First, it’s important to understand how a CGM works.
Continuous glucose monitor accuracy can differ from other glucose tests and devices (like glucose meters) because they measure interstitial glucose levels (as opposed to blood glucose levels).
Interstitial glucose can take a little longer to diffuse and may be impacted by additional variables, so the accuracy of CGM readings can vary slightly from other tests.
While the accuracy of CGMs vs. finger sticks varies, CGM values are highly reliable when the technology is used correctly. For example, while the absolute value may vary at baseline compared to a gold-standard reference fasting glucose lab value, the most important thing to consider while using a CGM is the relative change in patterns and trends over time.
Use a CGM to track
It's a good idea to verify the calibration of your CGM device. You can do this with a reference fasting glucose lab value or finger-stick glucometer reading taken while fasting since this is when your glucose levels may be more stable. This can increase the accuracy and effectiveness of CGM readings.
With the Nutrisense CGM program, you can discuss these CGM readings with an expert nutritionist. Your nutritionist can help break all the data down into easy-to-understand insights.
You can then use these insights to incorporate micro changes in your lifestyle and dietary habits as you work towards your wellness goals.
“My CGM experience was incredibly eye-opening. My top three takeaways are:
1. How quality sleep (or lack thereof) impacts blood glucose levels the following day.
2. How weightlifting specifically has a significant impact on blood glucose levels.
3. How stress, like a stressful meeting at work, impacts my blood glucose levels.”
“One takeaway from the CGM program was that although I thought I was in tune with my diet, I found there were quite a few habits I could identify that needed improvement if I wanted to optimize my health for the long term.
There really are no shortcuts to health. You just get more educated through the journey, which allows you to make smarter decisions.”
“I think using a CGM provides more than accountability; it’s information! These data points and experiments help us learn about our bio-individuality, which helps us make more informed decisions in the future.”
