<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 based on the idea that our ancestors ate foods that were available in the Paleolithic era, which lasted from 2.5 million years ago to 10,000 years ago. This means that people who follow the Paleo Diet eat foods like meat, fish, eggs, vegetables, fruit, nuts, and seeds, while avoiding grains, legumes, dairy products, and processed sugars. Proponents of the Paleo Diet claim that this way of eating can help with weight loss, reduce inflammation, improve heart health, and boost brain function.
