How the Glycemic Load Calculator works

This Tolyo.app free online tool uses the standard formula:GL = (GI × carbs per serving) ÷ 100. GI measures the speed of rise; GL also considers how much you eat.

Quick tips

  • • GL ≤ 10: low • 11–19: medium • ≥ 20: high (per serving).
  • • Larger portions raise GL even if GI is the same.
  • • Fiber, protein, and fat can blunt spikes when eaten together.

Example

Food with GI 55 and 30 g carbs per serving → GL = (55 × 30) ÷ 100 = 16.5 (medium).
