Protein is essential to help build muscles and to maintain normal bodily functions. However, most people do not know how much protein is enough for them on a daily basis. This amount of daily protein intake varies depending on your normal calorie diet. When I say diet, I am referring to the amount of food one needs to eat to maintain their normal body weight. For some people it is less important to know how much it costs to eat the required amount of protein every day, but those who want to change their diets to build muscle mass may be interested in how much this change would cost on a daily basis. Essentially, this website has broken down a few key calorie intake levels and what it typically costs to achieve those protein levels. It also briefly talks about differences between different types of food costs and the potential to spend less on protein depending on your preferences.
