Frequently asked questions about Low Glycemic Index Treatment (LGIT) Edited by Heidi H. Pfeifer, RD, LDN, Clinical Dietitian at Massachusetts General Hospital

1. What is the Low Glycemic Index Treatment (LGIT)?
The LGIT is a special high fat diet similar to the ketogenic diet that is used for difficult to treat seizures. It focuses on both the type of carbohydrate, low glycemic index, as well as the amount of carbohydrate based on portion sizes and household measurements. The glycemic index (GI) is a measure of the effect of carbohydrates on blood sugar levels.

When carbohydrates are digested, they release glucose into the bloodstream. Carbohydrates that digest rapidly have a high GI. Carbohydrates that are digested slowly have a low GI. Foods are rated based on their GI values ranging from zero to 100. The LGIT includes foods that have a GI of 50 or lower. In addition to the GI, the digestion of a carbohydrate food is slowed by foods that are eaten at the same time that contain either fat or fiber. Therefore, meals are balanced with sources of fat, protein and a low glycemic index carbohydrate.
