The Green Light Diet, also known as the G.I. Diet, is a diet plan that focuses on incorporating nutritious low-glycemic, or “green light,” foods into your diet while restricting the intake of high-glycemic foods. Low-glycemic foods are fairly high in fiber and low in calories, both of which aid weight loss and improve overall health.
Glycemic Index
Carbohydrates are macronutrients primarily used for energy and sparing muscle protein. They are broken down to the sugar glucose, which is the main source of energy for cells. However, not all carbohydrates have the same impact on blood glucose levels. The glycemic index is used to measure the effect of carbohydrates on blood glucose levels. Low-glycemic carbohydrates digest slowly and keep blood glucose levels stable, whereas high-glycemic carbohydrates digest rapidly and significantly increase blood glucose levels.
Green Light Foods
The Green Light Diet encourages the intake of low-glycemic foods while minimizing the intake of high-glycemic foods. These green light foods include cherries, broccoli, green beans, sweet potatoes, oats and nuts. Green light foods help control blood sugar levels, which in turn helps reduce hunger and increases satiety. On the other hand, high-glycemic foods, such as white potatoes, white bread, bagels and watermelon, are limited on the Green Light Diet since they increase blood sugar levels and boost hunger pangs.
Diabetics
Increasing the intake of low-glycemic foods can be an effective strategy for weight loss and controlling blood sugar levels for diabetics, according to research reported in the January-February 2006 issue of “Diabetes Education.” Scientists discovered that type 1 and 2 diabetics adhering to a low-glycemic diet plan for up to 36 months experienced improvements in blood sugar control and decreases in body mass index, an indicator of body mass.
Caution
The Green Light Diet seems to be effective for improving overall health, particularly for those with diabetes or weight issues. Before you start a diet plan, consult your health care provider.
