Definition: The Glycemic Index, (or GI), ranks foods based on their effect on blood sugar in your body. Each food on the Glycemic Index receives a "score" according to how much your blood sugar level increases within a few hours of eating it. When following any weight loss diet based on this concept, you'll be choosing from foods that have a low GI rating
Pronunciation: glie-see-mick
Also Known As: GI
Examples: The NutriSystem Nourish diet plan is based on the Glycemic Index.
