We created challenges to help you learn in real-time how different factors impact your personal blood sugar responses. These blood sugar challenges are completely optional and are designed for your own learning. They do not contribute to your results. We recommend doing these challenges as your first meal of the day on Days 1-5 of ZOE 102.

You'll put some concepts to the test to help you learn about how you can make all the foods you love work for you. Your data will also contribute to helping further science for everyone.

In this article, you'll find:

  • An overview of your blood sugar challenges

  • How to do your blood sugar challenges

  • How to prepare for your blood sugar challenges

  • Extra credit blood sugar challenges

How to do your blood sugar challenges

Here's what you'll need to do for each of your core blood sugar challenges:

  • Fast overnight for at least 8 hours

  • Eat your meal

  • Log it in your app

  • Check your blood sugar readings on your reader (or LibreLink app if you have it), 3 hours after your meal

  • Complete your blood sugar challenge reflection quiz

To get accurate results that you can compare with your other challenges, we recommend that you:

  • Eat your meal on an empty stomach

  • Fast for 3 hours

  • Limit or avoid exercise during your fast

These restrictions above are optional for more accurate blood sugar comparisons. Your official results won't be affected by whether or not you stick to them.
