Many bodybuilders follow the gylcemic index (GI) religously, and they shouldn't! Why so? Well, the GI is based on eating carbohydrates on an empty stomach without the addition of protein, lipids, fiber, water, etc. Therefore, it obviously has it's shortcomings and is not the be all end all choice for chosing our carbohydrate sources. Truth is, it's quite irrelevant when it comes to bodybuilding purposes. Let's take white potatoes for example. This food species is often avoided mainly because of it's high GI rank. Foolish. White potatoes are a very nutritious food and should be incorporated in a sound nutrition program. See, we're already spotting shortcomings challenging the elements and principles of the GI. But wait, there's more. The GI of that white potato can be drastically altered by combining it with the addition of protein, lipds, fiber, and other carbohydrates. In conclusion, the GI should not be followed religiously by bodybuilders and nutrient-density should be the main principle in one's nutrition plan, not the GI.
