I hear some folks ask for a protein shake after a workout. Should I just have protein instead of carbs?
No! You must combine carbs with the protein. Protein contains the building blocks to rebuild the tissue that you are breaking down and carbs contain the energy that will refuel your batteries and carry the protein molecules back to where they can begin to do their work!
If you just give your body protein post-workout, your body will use it for energy replacement, especially if carbs are not present. Over time your body will become dependent on protein for energy and you will literally waste all of those valuable amino acids. You see, your body will adapt to what you teach it. Remember, immediately following a workout your body requires glycogen. Glycogen comes from carbs.
By just drinking protein after a workout, your body metabolizes protein into glucose because that’s what your body requires at that moment. Your body then excretes all of those valuable amino acids as waste. But if you combine carbs with protein in a three to one ratio respectively, the protein molecule sits on the back of the carb molecule and they race back into your muscles together. In other words, the carb molecule acts as a transporter for protein.
