Since protein cannot be stored in the body, it must be consumed so that it’s readily available for muscle repair and growth. For this reason, I recommend lean protein be included with every meal. Many protein sources are animal products and many animal products contain saturated fat. Saturated fat has been linked to many dangerous effects on the body. For this reason, it’s important to be aware of lean sources of protein. I have included a list of lean sources of protein at the bottom of this article.
