How to Compare Zones


The Zone comparison feature allows you to visualize different glucose responses between two or more zones.

How to Compare Zones from your Timeline:
  1. Select a meal you'd like to compare from the Timeline
  2. Select the three dots at the top right corner of the screen 
  3. Select Compare Zone
  4. Select the plus button and search for another meal you'd like to compare it to
  5. Select Compare.
  6. On the Compare Zones screen, you'll see the glucose response of the zones you selected. They're color-coded for ease of viewing.

Whatโ€™s the difference between the Absolute and Relative graphs?

In the relative glucose data graph, the baseline for both zones is set to zero. Both meals start at 'zero' glucose mg/dL, and you can see how much increase or decrease there is for each line. We call this a relative graph because you can compare the two logs in relation to each other.

Absolute graphs, on the other hand, will display the actual glucose values during that time. You can see what your glucose levels were at the start of the zone and the value for the spike. This is a way to see that a stable meal is a stable meal regardless of what your starting glucose levels are.

๐Ÿค” Why you might want to Compare Zones: Compare Zones allows you to see how the same meal or ingredient performs against different behavioral factors and macronutrient context, such as:

  • Changing the order of the meal to try fat, fiber, and protein first.
  • Adding exercise like a post-meal walk.
  • Trying the same meal at different times of the day.
  • Trying the same meal with different amounts of sleep the night prior.
