"The Paleolithic and Paleo Diet (also popularly referred to as the caveman diet) is a nutritional plan based on the ancient diet of paleolithic man that consisted of wild plants and animals. The Paleolithic word signifies a period of about 2.5 million years duration that ended around 10,000 years ago with the development of agriculture. Centered on pre-agricultural foods, the "contemporary" Paleolithic diet consists mainly of meat, fish, vegetables, fruits, roots, and nuts, and excludes grains, legumes, dairy products, salt, refined sugar, and processed oils.
That’s right. No grains, dairy, beans, or vegetable oils of any kind. It sounds difficult, but once you do it, you’ll feel better than you thought you could. You’ll feel lighter on your feet… You’ll sleep better… You can relax and just eat without feeling guilty!”
