Lowering the GI and GL (glycemic index and load) is the sure way to permanent weight loss and optimum health—and this ingenious mix-and-match key makes the diet so simple to follow. No tables, no calculations: the work’s already done to assure the right balance of foods. Each recipe is color-coded in red, amber, or green. Choose a red, and then select one amber and two green or three green for the rest of the day. Pick two amber, and the other two must be green. Or go all green! And don’t worry, all the dishes are delicious!
