This diet goes by many names: the Paleo Diet, the Caveman Diet, the Stone Age Diet or the hunter-gatherer diet. Whatever your preference, this eating plan is based on the food consumed during the Paleolithic era that ended about 10,000 years ago. This means that the suggested foods can be hunted, fished or gathered. This includes foods such as pork, seafood, eggs, fruits, nuts and vegetables. Foods to avoid include grains, legumes, dairy products, salt, refined sugar and processed oils.
The only downfall to this diet, says Hardy, is that once again the food limitations make it difficult to maintain. There may also be problems with receiving all the necessary nutrients derived from legumes, whole grains and reduced-fat dairy products [sources: Zelman; Hardy].
