At its core, Paleo is a lot more lifestyle than it is a diet. A Paleo lifestyle is about eating real, whole, natural foods and avoiding all processed foods.You see, the modern diet is exactly that, it's modern. Humans ate in a Paleo style since the beginning of time before starting the agricultural revolution where we started to eat grain and sugar- based foods, as well as processed foods.The idea behind Paleo is to eliminate those processed foods, chemicals, vegetable oils and other new additions to the modern diet that can be detrimental to our lifestyle, from how we move to our energy levels to how we feel on a daily basis.
