You're probably not going to notice too much of a difference. Your metabolism will be slightly elevated during the day if your morning cardio is intense. However, pay attention to how your evening workouts are affected. Because if you're getting less sleep because of this new plan, you might be more tired during the day and your workouts might suffer - in which case, doing the morning cardio will have a negative impact on your progress.
Another note is that your breakfast/meal after your morning cardio, should be one of your biggest meals of the day (whether you do cardio in the morning or not), so a Muscle Milk RTD is probably not cutting it!
