Proteins are the building blocks of our bodies. Present in all body tissues (such as muscles and skin), proteins make up the second largest portion of our body weight. Only water outweighs proteins, securing the top position of making up about 70% of our body weight.

Proteins are like our bodies' superintendents with many responsibilities. They build and repair tissues, fight off infections, and transport oxygen. Together with carbohydrates and fats, proteins are also our bodies' energy source. Just like carbohydrates, proteins generate four calories per gram. Nevertheless, our bodies usually consider proteins the back-up energy providers. Therefore, unless we exclude both carbohydrates and fats from our diet, we don't rely on proteins to get us energized.
