Low-carbohydrate diets or low-carb diets are dietary programs that restrict carbohydrate consumption, often for the treatment of obesity or diabetes. Foods high in easily digestible carbohydrates (e.g., sugar, bread, pasta) are limited or replaced with foods containing a higher percentage of fats and moderate protein (e.g., meat, poultry, fish, shellfish, eggs, cheese, nuts, and seeds) and other foods low in carbohydrates (e.g., most salad vegetables such as spinach, kale, chard and collards), although other vegetables and fruits (especially berries) are often allowed. The amount of carbohydrate allowed varies with different low-carbohydrate diets.

Such diets are sometimes 'ketogenic' (i.e., they restrict carbohydrate intake sufficiently to cause ketosis). The induction phase of the Atkins diet[1][2][3] is ketogenic.

The term "low-carbohydrate diet" is generally applied to diets that restrict carbohydrates to less than 20% of caloric intake, but can also refer to diets that simply restrict or limit carbohydrates to less than recommended proportions (generally less than 45% of total energy coming from carbohydrates).[4][5]

Low-carbohydrate diets are used to treat or prevent some chronic diseases and conditions, including cardiovascular disease, metabolic syndrome, high blood pressure, and diabetes.[6][7]

As with the Paleolithic diet, several advocates of low-carbohydrate diets have argued that these diets are closer to the ancestral diet of humans before the origin of agriculture, and humans are genetically adapted to diets low in carbohydrate.[8] Direct archaeological or fossil evidence on nutrition during the Paleolithic, when all humans subsisted by hunting and gathering, is limited, but suggests humans evolved from the vegetarian diets common to other great apes to one with a greater level of meat-eating.[9] Some close relatives of modern Homo sapiens, such as the Neanderthals, appear to have been almost exclusively carnivorous.[10]

A more detailed picture of early human diets before the origin of agriculture may be obtained by analogy to contemporary hunter-gatherers. According to one survey of these societies, a relatively low carbohydrate (2240% of total energy), animal food-centered diet is preferred "whenever and wherever it [is] ecologically possible", and where plant foods do predominate, carbohydrate consumption remains low because wild plants are much lower in carbohydrate and higher in fiber than modern domesticated crops.[11] Primatologist Katherine Milton, however, has argued that the survey data on which this conclusion is based inflate the animal content of typical hunter-gatherer diets; much of it was based on early ethnography, which may have overlooked the role of women in gathering plant foods.[12] She has also highlighted the diversity of both ancestral and contemporary foraging diets, arguing no evidence indicates humans are especially adapted to a single paleolithic diet over and above the vegetarian diets characteristic of the last 30 million years of primate evolution.[13]

The origin of agriculture brought about a rise in carbohydrate levels in human diets.[14] The industrial age has seen a particularly steep rise in refined carbohydrate levels in Western societies, as well as urban societies in Asian countries, such as India, China, and Japan.

In 1797, John Rollo reported on the results of treating two diabetic Army officers with a low-carbohydrate diet and medications. A very low-carbohydrate, ketogenic diet was the standard treatment for diabetes throughout the 19th century.[15][16]

In 1863, William Banting, a formerly obese English undertaker and coffin maker, published "Letter on Corpulence Addressed to the Public", in which he described a diet for weight control giving up bread, butter, milk, sugar, beer, and potatoes.[17] His booklet was widely read, so much so that some people used the term "Banting" for the activity usually called "dieting".[18]

In 1888, James Salisbury introduced the Salisbury steak as part of his high-meat diet, which limited vegetables, fruit, starches, and fats to one-third of the diet.[original research?]
