What is the Glycemic Index (GI)?

The Glycemic Index is a scale from 0 to 100 that ranks carbohydrate-containing foods by how quickly they raise blood sugar levels after eating. Foods with a low GI (55 or below) are digested slowly and cause a gradual rise in blood sugar, while high GI foods (70 or above) cause a rapid spike.

What is Glycemic Load (GL) and how is it calculated?

Glycemic Load accounts for both the quality (GI) and quantity of carbohydrates in a serving. It is calculated as GL = GI x net carbohydrates (grams) / 100. A GL of 10 or below is low, 11-19 is medium, and 20 or above is high.

Why is GL more useful than GI alone?

GI only tells you how fast a food raises blood sugar, not how much. Watermelon has a high GI of 76, but a typical serving has few carbs, giving it a low GL of about 8. GL gives a more complete picture of a food's actual impact on blood sugar.

Is this glycemic index tool really free?

Yes, this GI/GL calculator is completely free to use with no signup, no account creation, and no hidden fees. Your data is stored locally in your browser. It is provided by FreeWWW.com, a platform dedicated to free online tools.

How can I use GI and GL to improve my diet?

Focus on choosing low and medium GI foods, pair high GI foods with protein or healthy fats to lower the overall glycemic response, and use the meal tracker to keep your daily glycemic load within a healthy range (generally under 100).
