What is this calculator?
Estimate meal glycemic load from GI and carbohydrate amount. The formula, a worked example, and a reference table are below. Results are for education only, not medical advice.
How it works
GL = (Glycemic Index × digestible carbohydrate grams) ÷ 100.
Example
GI 55, carbs 40 g → GL = (55×40)/100 = 22 (higher-GL serving illustration).
Reference Table
| Value | Meaning |
|---|---|
| < 10 | Lower per-serving GL |
| 10–19 | Moderate |
| 20 | Higher |
FAQ
GI tables vary?
Yes—use consistent references within a meal plan.
Protein and fat?
They blunt glucose rise but GL focuses on carb portion × GI.
Diabetes meds?
Carb counting and clinician plans override casual GL estimates.
Whole fruit?
Fiber changes effective carb absorption versus juice.
