The Paleolithic diet derives its name from the Paleolithic age. As the name suggests, in this diet the people eat food that the Paleolithic people used to eat. So, the Paleolithic diet includes meats and fish in abundance and also fresh vegetables and fruits. Shannon Cooper started following the diet in 2010 and is sticking to it since then. According to her, the diet has transformed her life completely. This diet is all about unprocessed and natural food. Well, adhering to a diet like this is an easy thing for a fully grown adult but how an infant like Grace was going to respond to that, was yet to be seen.
