The Paleo diet has been promoted as the optimal diet, offering the eater a plethora of benefits including weight loss, disease prevention, and improved health. It is designed to mimic what our hunter-gatherer ancestors ate and includes grass-fed meats, nuts, seeds, eggs, fruits, vegetables, and some oils. Foods to avoid on the diet include all grains, cereals, dairy, beans, and potatoes, as well as processed foods, sugar, salt, and refined oils.
