The G.I. (Glycemic Index) Diet: If You Understand a Traffic Light, You'll Understand This Diet (Updated and Revised)

Backed by the science of the glycemic index, The G.I. Diet places every type of food into one of three color-coded categories: Green - make these foods the centerpiece of your diet; Yellow - eat occasionally, after you've achieved your ideal weight; and Red - avoid. For example, quickly digested white bread, including bagels and rolls, causes blood sugar to spike and hunger to return quickly. It's "red." Slowly digested stone-ground whole-wheat bread, which gives a much-longer feeling of satiety, is "green." The diet is a cinch to stick to, truly healthful, and couldn't be easier to follow. Includes recipes, snack ideas, a shopping list, and tips for dining out.
