The Glycemic Index Meal Planner software calculates the overall Glycemic Index (GI) and Glycemic Load (GL) for meals and the day to help build a healthy diet for weight loss, diabetes, and sports performance. It also provides Carbohydrate, Calorie, Protein, and Fat analysis by meal and day.

The Glycemic Index - a measure of carbohydrate quality based on how quickly food raises blood glucose (blood sugar) levels - is a dietary key to health say the authors of "The New Glucose Revolution". Low-GI foods, by virtue of their slow digestion and absorption, produce gradual rises in blood sugar and insulin levels, and have proven benefits for health.

The Glycemic Index is highly recommended by both Atkins and South Beach diets.
