I get the feeling if I don't drink protein shake after workout I feel low. Is it a mind thing or is it really a nutritional fact that hits the body? I usually don't go to gym and it has been 1 year since I could afford any supplements so I stopped it as I think I will be putting my body under stress if I don't have protein shake.
Is it really true or just my mind being lazy? What are the alternatives when one does not have protein powder to gulp down?
