Formula
GL = (GI x Carbs per serving) / 100
Glycemic Load Scale
Why GL is Better Than GI Alone
Glycemic index only measures how fast a food raises blood sugar. Glycemic load also accounts for how much carbohydrate is in a typical serving. Watermelon has a high GI (72) but low GL (4) because a serving has few carbs.
Example Calculation
Calculate GL for a food with GI 55 and 30 g carbs per serving.
- 01GL = (55 x 30) / 100 = 16.5.
- 02This is a medium glycemic load.
