We could say that a paleo diet takes us back to “the roots” in that it tries to emulate what our Paleolithic ancestors ate before the advent of agriculture. Followers of the paleo diet believe that the human body is genetically mismatched to the modern-day diet that emerged with farming practices 10,000 years ago, and that a paleo diet is the more natural alternative.
So, what do people on the paleo diet eat? The emphasis is on unprocessed, whole foods, like meat, eggs, seafood, vegetables, fruit, nuts, seeds, and healthy fats. The paleo lifestyle is also often accompanied by a great deal of exercise to further imitate the hunters-gatherers who were always on the move. Many paleo diet followers do strenuous exercise like Crossfit or triathlon.
