This is not typical of more recently devised paleo diets Loren Cordain's – probably the most popular – instead emphasizes animal products and an avoidance of processed food. Eaton and Konner, for example, wrote a 1988 book The Paleolithic Prescription with Marjorie Shostak, and it described a diet which is 65% plant-based. The basis of the diet is a re-imagining of what paleolithic people ate, and different proponents recommend different diet compositions. Some recent paleo diet variants emphasize the consumption of unprocessed animal products. The paleolithic or paleo diet is also sometimes referred to as the caveman or stone-age diet. In 2012 the paleolithic diet was described as being one of the "latest trends" in diets, based on the popularity of diet books about it in 20 the Paleolithic diet was Google's most searched weight-loss method. in physical education, who trademarked the words "The Paleo Diet" and who wrote a 2002 book of that title. These diet's ideas were further popularized by Loren Cordain, a health scientist with a Ph.D. The diet started to become popular in the 21st century, where it attracted a largely internet-based following using web sites, forums and social media. Eaton and Konner proposed a "discordance hypothesis" by which the mismatch between modern diet and human biology gave rise to lifestyle diseases, such as obesity and diabetes. In 1985 Stanley Boyd Eaton and Melvin Konner published a controversial article in the New England Journal of Medicine proposing that modern humans were biologically very similar their primitive ancestors and so "genetically programmed" to consume pre-agricultural foods. Voegtlin advocated a meat-based diet, with low proportions of vegetables and starchy foods, based on his declaration that humans were "exclusively flesh-eaters" until 10,000 years ago.
In his 1975 book The Stone Age Diet, gastroenterologist Walter L. In 1958, Richard Mackarness authored Eat Fat and Grow Slim, which proposed a low-carbohydrate "Stone Age" diet. Arnold DeVries advocated an early version of the Paleolithic diet in his 1952 book, Primitive Man and His Food. Densmore proclaimed that " bread is the staff of death", while Kellogg supported a diet of starchy and grain-based foods in accord with "the ways and likings of our primitive ancestors". Īdrienne Rose Johnson writes that the idea that the primitive diet was superior to current dietary habits dates back to the 1890s with such writers as Emmet Densmore and John Harvey Kellogg. On the other hand, following the diet can lead to nutritional deficiencies such as an inadequate calcium intake, and side effects can include weakness, diarrhea, and headaches. There is some evidence that following it may lead to improvements in body composition and metabolism compared with the typical Western diet or compared with diets recommended by some European nutritional guidelines.
Anthropological science has found that human diets in paleolithic times were more varied and less meat-centric than had previously been assumed.Īdvocates promote the paleolithic diet as a way of improving health. This evidence undermines a core premise of the paleolithic diet - that human digestion has remained essentially unchanged over time. In the 21st century, the sequencing of the human genome and DNA analysis of the remains of early humans have found evidence that humans evolved rapidly in response to changing diet. As of 2019 the paleo-diet industry was worth approximately US$500 million. Voegtlin popularized a meat-centric "Stone Age" diet in the 21st century the best-selling books of Loren Cordain popularized the Paleo diet. Historians can trace the ideas behind the diet to "primitive" diets advocated in 19th century. The diet avoids processed food and typically includes vegetables, fruits, nuts, roots, and meat and excludes dairy products, grains, sugar, legumes, processed oils, salt, alcohol, and coffee. The Paleolithic diet, Paleo diet, caveman diet, or stone-age diet is a modern fad diet consisting of foods thought by its proponents to mirror those eaten by humans during the Paleolithic era.
