Low GI treatment (LGIT) The LGIT is a high fat diet similar to the ketogenic diet. It focuses on both the type and amount of carbohydrate consumed. The Glycemic Index (GI) is a measure of the effect of carbohydrates on blood sugar levels. Foods are rated on their GI values ranging from 0 to 100. The LGIT includes foods that have a GI of 50 or lower and typically restrict carbohydrates to around 40g to 60g per day. The digestion of carbohydrate food is also slowed by eating foods containing fat or fibre at the same time. This treatment is normally used in older children as it includes a lot of fibre, which can be challenging for younger children. LGIT contains: 60% fat 30% protein 10% carbohydrate Manage Cookie Preferences
