It's common knowledge around here that you should consume a simple carb, like fruit juice, with your post-workout shake in order to increase insulin levels and get those amino acids to your muscles. But what about for regular meals?
For example, let's say I just drink a protein shake with 0 carbs. Protein doesn't affect my blood sugar, and therefore insulin isn't produced. So does that mean that protein I took in was not utilized for my muscles and was basically wasted? It makes sense to me that one would have to eat a carb with their protein, yet I see a lot of people eating just protein (ie a shake as a meal replacement.)
Also, how exactly does eating a protein before doing cardio protect your muscles from being broken down as energy? Your body doesn't build muscle just because you eat protein, and using the calories from the protein source as your energy for the cardio defeats the purpose of doing cardio in the first place.
Sorry for the long winded questions, but I'd love to know the answers. Been bugging me for a while.

Having the amino acids from the protein shake available for the body during a workout prevents the body from scavenging them from its own muscles. Your body is resourceful and will dip into its own tissues for what it needs. If there is no fuel it will eat itself (that is a very basic explanation, but you get the idea, right?)
I think it is good to have some complex carbs with every meal, vegies and brown rice or a sweet poatato. The only time you really want the simple carbs is after your workout.
