In a GI Diet, your aim is to eat more of low GI food and less or high GI food. A GI Diet uses the Glycemic Index to guide your eating plan.
The Glycemic index is a guide developed to help improve blood sugar control in diabetes. The Glycemic index classifies carbohydrate-containing foods according to their potential of raising your blood sugar level.
Although the GI Diet is not a true low-carbohydrate diet because you don't have to count carbohydrates. Nor is it a low-fat diet. But a low GI Diet does steer you toward certain types of food that is low-fat and low carbohydrates.
