My mother always asked, "why don't you just eat real food?", when it came down to supplements like whey protein, creatine, monohydrate, and pre-workout. The truth of the matter is that when it comes to lifting and fitness, you can absolutely accomplish all of your goals by only eating real foods. At the same time, supplements sometimes make it easier to accomplish these goals by saving time as well as making your nutrition requirements more manageable. Supplements are more inexpensive than ever so it makes them great additives to any diet style or fitness plan. Just remember that a supplement can never replace real food.
