Glycemic Load & Glucose Response Calculator (GL & GI Harvard)

Metabolic glycemic impact audit. Unlike isolated Glycemic Index (GI), Glycemic Load (GL) measures real blood glucose impact by accounting for the exact portion size of net carbohydrates consumed.

Formula: Harvard / ADA Formula: Glycemic Load (GL) = (Glycemic Index × Net Carbs_g) / 100. Serving GL Tiers: Low (≤ 10), Medium (11-19), High (≥ 20).

In-Depth Guide & Mathematical Methodology

🍇 Why Glycemic Load (GL) Beats Glycemic Index (GI)

Watermelon Example: Watermelon has a high GI (72) but very low net carbs per serving, yielding a Low GL of only 5.

Insulin Control: Low GL meals (GL ≤ 10) prevent rapid blood sugar spikes, supporting appetite control and insulin sensitivity.
