Glycemic Load(GL)
Definition
A metric that accounts for both the quality and quantity of carbohydrates in a food serving, calculated as GI multiplied by grams of carbohydrates per serving divided by 100. A glycemic load below 10 is considered low, 11 to 19 is medium, and 20 or above is high. Glycemic load is a more accurate predictor of CGM-measured glucose response than glycemic index alone because it factors in actual portion size.
Why “Glycemic Load” Matters for Glucose Monitoring
Understanding glycemic load is essential for anyone using or evaluating a continuous glucose monitor. This concept directly affects how CGM devices are designed, how glucose data is interpreted, and how clinical decisions about blood sugar management are made.
This term applies broadly across all continuous glucose monitors and is foundational knowledge for interpreting CGM data, whether you are managing diabetes or using a sensor for metabolic wellness.
