Purpose

The purpose of a glycemic index (GI) diet is to eat carbohydrate-containing foods that are less likely to cause large increases in blood sugar levels. The diet could be a means to lose weight and prevent chronic diseases related to obesity such as diabetes and cardiovascular disease.

Why you might follow the GI diet

You might choose to follow the GI diet because you:

• Want to lose weight or maintain a healthy weight
• Need help planning and eating healthier meals
• Need help maintaining blood sugar levels as part of a diabetes treatment plan

Studies suggest that a GI diet can help achieve these goals. However, you might be able to achieve the same health benefits by eating a healthy diet, maintaining a healthy weight and getting enough exercise.

Check with your doctor or health care provider before starting any weight-loss diet, especially if you have any health conditions, including diabetes.
