The Complete
Glycemic Index Guide

GI vs GL — what actually matters for blood sugar, with food swap tables that cut glycemic load by up to 97%.

Whole foods arranged for optimal glycemic control

Not all carbohydrates are created equal. The Glycemic Index (GI) measures how quickly a food raises blood sugar, while the Glycemic Load (GL) tells you the real-world impact based on a typical serving. For managing Type 2 Diabetes, GL is the metric that matters most.

GI vs GL: The Key Difference

Glycemic Index (GI)0–5556–6970+
Glycemic Load (GL)0–1011–1920+

Smart Food Swaps

Small changes, big impact. These swaps can reduce the glycemic load of your meals by 40–97%:

White rice (GL 33)Cauliflower rice (GL 1)-97%
White pasta (GL 23)Zucchini noodles (GL 2)-91%
White bread (GL 10)Sprouted grain bread (GL 6)-40%
Mashed potatoes (GL 18)Mashed cauliflower (GL 2)-89%
Orange juice (GL 12)Whole orange (GL 5)-58%
Cornflakes (GL 23)Steel-cut oats (GL 7)-70%

Best Low-GL Foods for T2D

GL: 0

Proteins

Chicken, fish, eggs, tofu, tempeh — pure proteins have zero glycemic impact and should anchor every meal.

GL: 0–3

Non-Starchy Vegetables

Broccoli, spinach, kale, cauliflower, zucchini, asparagus, bell peppers — eat generously.

GL: 0

Healthy Fats

Olive oil, avocado, nuts, seeds, fatty fish — these slow glucose absorption and improve insulin sensitivity.

GL: 5–10

Smart Carbs

Lentils, chickpeas, black beans, quinoa, steel-cut oats — high fiber slows their glucose release.

The Fiber Multiplier

Adding fiber to a meal physically slows carbohydrate digestion. A study in Diabetes Care found that adding 10g of fiber to a meal reduced the post-meal glucose spike by up to 25%. This is why Fortivore targets 8g+ fiber per meal.
