The "Caveman Diet," also known as the Paleo Diet, is based on the idea of eating like our ancient ancestors. It emphasizes whole, unprocessed foods that would have been available to humans during the Paleolithic era. This includes lean meats, fish, fruits, vegetables, nuts, and seeds, while avoiding grains, legumes, dairy, and processed foods. Proponents of the Caveman Diet believe it can lead to various health benefits, such as weight loss and improved energy levels. The diet aims to mimic the natural eating patterns of early humans, promoting a return to simpler, more nutritious food choices.
