Glycemic index and serving-size calculator
Glycemic Load Calculator
Estimate glycemic load for common foods by combining glycemic index, carbohydrates per serving, and serving size in grams or ounces.
Calculate glycemic load from GI and serving size
Glycemic load is calculated as glycemic index multiplied by the grams of available carbohydrates in your serving, divided by 100. Use the interactive app to search foods, check GI values, convert serving sizes, and compare low, medium, and high glycemic load estimates.
