What is a Paleo Diet?

With the New Year upon us a LOT of people will be dieting and based on what I've seen the most popular diet fad right now is the Paleo diet. So what is a Paleo diet?

According to Wikipedia it's not Paleo at all, it's actually called Paleolithic diet and it's essentially the caveman diet. Wait, does that mean you eat raw mean and grunt a lot during this diet? Uh, no.

The Paleolithic diet, also popularly referred to as the caveman diet, Stone Age diet and hunter-gatherer diet, is a modern nutritional diet designed to emulate, insofar as possible using modern foods, the diet of wild plants and animals eaten by humans during the Paleolithic era.[1] Proponents of the diet therefore recommend avoiding any foods that they claim were not available to humans at that time, including dairy products, grains, legumes, processed oils, and refined sugar. The Paleolithic diet is a fad diet[2] that has gained popularity in the 21st century.

If you like meat, this diet is for you! Here's the deal, eat lots of meat & fiber, but not a lot of carbohydrates, but only those foods that were available to caveman. This sounds a lot like the Atkins diet to me.
