Eva, the GI is a measure of foods that cause changes in insulin levles, AKA carbohydrates. Proteins would not be on that list, because they are not carbohydrates

While exessive protien can be turned into glucose by the body, and many diabetics are senstive to excessive levels of protein, this is not an issue when you're LCing - the process by which proteins are turned into glucose (gluconeogensis) is done in the absence of insulin.
