What this calculator does
Glycemic load works out combines a food’s glycemic index with the actual carbohydrate in a serving. Enter your own figures above and the answer updates as you type: nothing is fixed in the code, so the result reflects exactly the numbers you supply.
The formula this calculator evaluates is printed under the tool and explained below, so you can check the working by hand or reuse it in a spreadsheet.
The formula
FormulaGlycemic load = (Glycemic index × carbohydrate grams per serving) / 100
The inputs explained
| Field | What to enter |
|---|---|
| Glycemic index (0-100 scale) | A number. Starts at 55. |
| Carbohydrate per serving (g) | A number, measured in g. Starts at 50. |
Worked examples
Every figure in the tables below is produced by this page’s own calculator at build time, so the numbers and the tool always agree. Select any row to load that scenario.
How the answer changes with glycemic index (0-100 scale)
Every other input is held at the calculator’s starting values while glycemic index (0-100 scale) varies. Select any row to load that scenario into the calculator.
How the answer changes with glycemic index (0-100 scale)
