Hi there! Thanks for your question. There is a lot of information about protein shakes, especially when it comes to drinking them before or after exercising. Protein is an important source for energy and we could usually get enough protein in the foods we eat.
EatFresh.org has tons of great recipes that use lean proteins and vegetarian proteins. Have you tried non-meat sources of proteins? Check out beans, nuts and seeds,and legumes. By adding a variety of different lean proteins and vegetarian sources of proteins throughout the day, you will get enough protein to help with your energy level and keep muscle mass.
Enjoy adding new sources of protein in your diet!
