Glycemic Load Versus Glycemic Index – What is the Difference?

As mentioned in a previous post titled, “What is the Glycemic Index”, the glycemic index tells us how fast the carbohydrates within a particular food enter into the blood as sugar.

Foods that rank high on the Glycemic Index have a tendency to short circuit weight loss efforts by triggering excess insulin to enter the blood thus shutting down the fat burning process.

TheGlycemic index, however, does not tell the entire story about how a particular food impacts the blood sugar and insulin levels because it ignores the quantity of carbohydrate within the food. For example: Watermelon has a fairly high Glycemic Index score of 76, however, because the majority of watermelon’s mass is WATER it has a low Glycemic Load of 3.
