Proteins are one of the three macronutrients necessary for healthy body function. Protein’s primary function (among others) is serving, in the simplest terms, as the “building block” of muscle. To gain or maintain lean muscle, protein is an absolute must.
Furthermore, understanding that the three macronutrient sources of calories are proteins, carbohydrates, and fats, a persons total caloric intake for the day must be some combination of calories from these three nutrients. Unless you want a vast majority of your calories to come from carbs and fats, proteins must make up a significant ratio of your daily caloric intake.
Unless you are getting all of your proteins from whole foods (meats, dairy, nuts) a protein supplement (whey protein shake) is a great way to get the protein you need.
