View Your Glucose Analytics
Make sure to also monitor your glucose statistics under the analytics tab on the main dashboard. You can view both your glucose statistics and charts. You can view this for the current day you have selected in the calendar or for a time range by adjusting the dates at the top.
The bar underneath each stat will be green if they are great, yellow if they are just okay, and red if some improvement is needed. The number to the left of each stat under “last” is your value for the previous day or range of dates. The value to the right under “change” is the change from the previous value to today’s value. In the image above, you can see the standard deviation for today is 10, while yesterday it was 9. So that is a 16% increase in standard deviation today.
Daily Average: This is the average of your daily glucose score.
Meals Average: This is the average of your meal glucose scores.
Mean: The average of all the glucose readings in the selected date range. Lower average glucose is typically indicative of fewer glucose spikes. When enough data is gathered, it can calculate an estimated hemoglobin a1c value. A great average is below 105.
Standard Deviation (SD): This reflects the amount of variability in your CGM readings. The larger the SD, the more you stray from your glucose average. It provides insight into your degree of glucose “swings” and your level of insulin sensitivity; the lower the number, the better. A great standard deviation is below 14. Important caveat: If you have major outliers, such as a one-time value of 400, this will alter the SD and cause an artificially high value.
Min: Your lowest glucose value within the selected date range.
Max: Your highest glucose value within the selected date range. Try to avoid repeated values above 140.
Time Within Range: The percentage of time that glucose levels are within the pre-set “green” area (70-140) in your Nutrisense app. The closer to 100%, the better. Important caveat: If you frequently have a fasting glucose < 70, this may alter your value. If you do not have any symptoms of hypoglycemia with this fasting value, then it is okay. You can adjust your upper and lower glucose thresholds under settings.
Median: This is your median glucose value. This is less affected by extreme outliers than the average glucose number. Aim for a median around 105 or lower.
Sleep average: This is your average glucose during your fasting window. You can set this customizable window by going to settings -> user -> fasting window.
Morning average: This is the last two hours of your fasting window and can provide an estimated fasting glucose value.
There are also statistics available for ketones, macronutrients, and habits if you are choosing to track this information.
The charts allow you to visualize your data as a graph. You can use the filter icon in the top right corner to hide or re-arrange charts.
There are glucose-related charts, such as your average glucose values by each hour of the day or by each day of the week. But there are additional charts for anything you might be logging, such as weight or stress. You can choose to view the charts by the current date, or by choosing a range of dates.
Additionally, you can find more analytics on your individual meal cards each time you log a meal. These are also important metrics to monitor to see how you respond to different foods! The first view of your meal card gives you an overview of your meal glucose response by giving you a glucose score. If you swipe right, you'll see a breakdown of that glucose information in further detail. Swipe right again for ingredient information. And swipe right a final time for macronutrient and nutrition information.
Each time you log a meal, you will see an associated number “score” with it. This is a number on a scale of 1-10, with 1 being a poor glucose response and 10 being excellent. This score takes into account your glucose information at the start of a meal until 2 hours later.
It combines 4 metrics:
1. Peak – this is how high your glucose goes during that 2 hours. We want to aim for a peak of 140 or less.
2. Exposure – this is your area under the curve for the meal response, or how much glucose exposure your body had during the 2-hour window. We want to aim for an area under the curve of 25 or less. This cut-off is based on population averages.
3. Stability – this is your delta, or how much your glucose changed in the 2-hour window. So you might have started at 70, and jumped to 130, and that would be a delta of 60. We want to aim for a shift in glucose of 30 or lower most of the time.
4. Recovery – this is how close your 2-hour glucose value is to your pre-meal glucose value. This shows us how well your body was able to respond to the meal and return back to baseline values!
