<human>: I've been hearing a lot of buzz about a new diet craze called Paleo. What is Paleo?
<bot>: Paleo is an eating plan that focuses on foods that were available during the Paleolithic era, which is the period of time from 2.6 million years ago to 10,000 years ago. This includes meat, fish, eggs, vegetables, fruits, nuts, and seeds. The goal of this diet is to mimic the way our ancestors ate, so it's considered a natural diet.
