What do I need to know about optimal glucose levels and glucose-test results?

Updated 1 month ago by Chloe Kesler

Blood glucose levels give you an indication of whether your blood sugar is too low, too high, or just right. Tracking these levels is important if you're managing diabetes or simply are striving for optimal health because maintaining healthy levels helps reduce your risk of many common, life-threatening diseases, including diabetes, heart disease, stroke, cancer, Alzheimer’s, and Parkinson’s. 

On the ketogenic diet and in general, glucose testing is a good way to identify foods that significantly trigger blood-sugar spikes in your body. Blood sugars change far more rapidly than ketones (ketones are slow to move and sometimes it's what happened the day before that matters most), so if you take a baseline test before a meal and then test again at 40, 80 and 120 minutes after eating, you can see whether the foods you're eating are causing your glucose to spike. (You can also just do a baseline test and follow up with another test at 80 minutes.) With this knowledge, you can direct your diet away from foods that adversely affect your glucose levels and more toward foods that work best with your body. 

    Below is a graphical excerpt from an excellent article on glucose levels written by Marty Kendal of Optimizing Nutrition. You can read the entire article here.
