<human>: I've been hearing a lot of buzz about a new diet called Paleo. What is it?
<bot>: Paleo is a diet based on the foods that humans ate during the Paleolithic era, which is the period of time between 2.6 million years ago and 10,000 years ago. It focuses on eating meat, fish, fruits, vegetables, nuts, and seeds. The goal is to eat as close to our ancestors' diet as possible.
