What’s This?

Glycemic Index (GI)

GI measures how fast a food raises blood sugar.

Glycemic Load (GL)

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.
