<human>: I've been hearing a lot about a new diet fad called Paleo Diet. What is it and does it work?
<bot>: The Paleo Diet is a popular eating plan that focuses on foods that are considered to be the healthiest for humans in the past, such as lean meats, fruits, vegetables, nuts, seeds, and healthy fats. It encourages people to avoid processed and refined foods and sugary snacks, and instead focus on natural sources of protein, vitamins, and minerals.
