Glycemic Load Calculator by TheCalcTools

How the Glycemic Load Calculator works

Enter the food’s glycemic index, the available carbohydrate in one serving and the number of servings.

GL is GI multiplied by carbohydrate grams, divided by 100.

Categories are for a single serving.

The formula

GL = GI × carbohydrate (g) ÷ 100

Worked example

Using the default values shown in the calculator:

Glycemic index (GI)70
Available carbohydrate per serving (g)30
Servings1
  1. GL = 70 × 30 ÷ 100 = 21.0 for one serving.
  2. Category: High (20 or more).

Result:

Glycemic load21.0
Category (per serving)High (20 or more)

Frequently asked questions

What is the difference between GI and GL?

GI ranks how fast a carbohydrate raises blood glucose per gram. GL also accounts for how much carbohydrate you actually eat.

Is it medical advice?
