Tells you how big that rise actually is once portion size is factored in.
Example:
Watermelon has a high GI (it digests quickly) but a low GL because a normal serving doesn’t contain many carbs so the actual blood-sugar impact is small.
Why it matters:
Understanding both GI and GL gives you a clearer picture of how foods affect your blood sugar both the speed of the rise and the true impact based on the portion you eat.
