“The Low Glycemic Index Treatment diet (LGIT) is a relatively new diet that was created by Dr. Elizabeth Thiele and dietitian Heidi Pfeifer at Massachusetts General Hospital about ten years ago. While it is still considered a high fat diet, it allows for greater freedom with 40 to 60 grams of carbohydrates, using only carbohydrates that are low on the glycemic index (GI) (<50). The GI is a measure of the effect of carbohydrates on blood sugar levels. The lower the number, the less the carbohydrate will alter your blood sugar level. When you hear the term “sugar rush,” that is often due to the rise of glucose in your bloodstream after consuming a sugar-rich food; foods that are high on the glycemic index raise the blood sugar levels in your body, and because all that goes up must come down, eventually the blood sugars will descend, causing the classic “crash” we’ve all felt hours”
