Why are you so particular? I never could understand this fascination for glycemic food and eating based on some diet plan. You yourself are in the best position to judge what is good for you and you should eat accordingly. Breakfast as well all know is the best and most important meal of the day and you must treat it accordingly. What you eat depends on how much you workout or how much energy you expend. Low glycemic smoothies are all the rage these days and I suppose this is something that you can try as well. If you must!
