What is it?
Have you heard about the 'Paleo Diet'?
Pros of the Paleolithic Diet
Cons of the Paleolithic Diet
"Debunking the Paleo diet"
Advocates for the Paleolithic Diet claim a person will lose weight without increasing exercise or moderating portions.
Numerous testimonies exist to support this claim.
Most advocates and testimonies support that the Paleo diet's weight loss is less restrictive than several diets because there is no portion control.
The diet has proven beneficial to people with Type 2 Diabetes and cardiovascular risk factors.
Research at the University of California has shown evidence that the diet can quickly benefit those with Diabetes.
Participants in a study improved blood sugar control, blood pressure control and blood vessel elasticity. They lowered levels of blood fats such as cholesterol. They achieved these results in less than three weeks.
In a 2007 twelve week comparative study of the Paleo diet and the Mediterranean diet (based on whole grains, low-fat dairy products, vegetables, fruits, fish, oils, and margarines) they found improved glucose tolerance independent of weight loss in both groups, but the improvement was significantly greater in the Paleolithic diet group.
People today are far less active than our caveman ancestors, who had to chase down their food or forage for it.
The diet should vary due to geography, season and opportunity but as modern humans, everything exists in grocery stores in extremely large proportions.
The diet bans not just processed foods, but all foods that weren't available to our stone-age ancestors.
The paleo diet, in a way, denies that we have evolved further than our biological ancestors in saying that our bodies can not process things which were not available during the hunter-gatherer period.
The diet ignores benefits of some more modern ways of eating, like calcium rich dairy and grains packed with fiber.
Meat today is no longer as lean as it used to be when its hosts ran wild, as most of the animals which we consume (and any you can find in your local supermarket) are domestic and farm raised.
Even if eating like a paleolithic man was reasonable, it is impossible. Almost every species of animal and plant is drastically different from its paleolithic predecessor. (Tomatoes, bananas, nuts, bovine, etc)
The diet ignores that, around this time, many children died when they were around 15. Few adults survived to live in their forties.
Hunter-gatherers sometimes went days without eating a fully nutritional meal, and it is believed that few if any were the fabulously muscular and toned men and women that we envision today. More likely, they were fit but extremely thin due to the strenuous activities they had to take part in to find their food every day.
47 of the 137 mummies examined of farmers, foragers and hunter-gatherers from around the world had, sometimes with advanced symptoms, hearts with clogged arteries.

2.5 Million to 10,000 years ago
The "Paleolithic Era" lasted from 2.5 mya to 10 kya
During this time stone tools started appearing suggesting a new way of life for primates
Ending around 10,000 years ago in the age of agriculture, this mark in time is what the "paleo" diet focuses on
*see "what is it" for details on what was presumably eaten during that time
The Paleo diet was first mentioned by Walter L. Voegtlin a gastroenterolgist in 1975 in the book he published;
The Stone Age Diet: Based on In-depth Studies of Human Ecology and the Diet of Man
He wrote it based on his personal dietary prescriptions to certain gastrointestinal diseases/problems
This diet wasnt widely noticed until S. Boyd Eaton and Melvin Konner published a paper in the New England Journal of Medicine
After this diet recieved attention from the medical community specifically among dietitions, it gained the attention of the average american looking for the next best way to lose weight. (or just eat more healthfully)
Now the diet is blogged, tweeted, facebooked, and instagramed about on a regular basis as it continues to be popular among the "healthy living" communities

Should you be eating a Paleolithic diet?
The simple answer is: no, you should not be eating a Paleolithic diet. Can you follow the diet? Sure. Does the diet provide benefits, especially to those with Type 2 Diabetes and cardiovascular problems? The scientific evidence says yes. The fact still remains that many other diets provide similar benefits, and the diet itself is more opinion than fact as to what our Paleolithic ancestors ate. To say there is some necessity for it and that you should be eating as the diet dictates is incorrect and ignores how adaptive our diets can be.
