Low-carbohydrate diets restrict carbohydrate consumption relative to the average diet. Foods high in carbohydrates (e.g., sugar, bread, pasta) are limited, and replaced with foods containing a higher percentage of fat and protein (e.g., meat, poultry, fish, shellfish, eggs, cheese, nuts, and seeds), as well as low carbohydrate foods (e.g. spinach, kale, chard, collards, and other fibrous vegetables). There is a lack of standardization of how much carbohydrate low-carbohydrate diets must have, and this has complicated research. One definition, from the American Academy of Family Physicians, specifies low-carbohydrate diets as having less than 20% carbohydrate content.There is no good evidence that low-carbohydrate dieting confers any particular health benefits apart from weight loss, where low-carbohydrate diets achieve outcomes similar to other diets, as weight loss is mainly determined by calorie restriction and adherence.An extreme form of low-carbohydrate diet – the ketogenic diet – was first established as a medical diet for treating epilepsy. Through celebrity endorsement it has become a popular weight-loss fad diet, but there is no evidence of any distinctive benefit for this purpose, and it carries a risk of adverse effects. The British Dietetic Association named it one of the "top 5 worst celeb diets to avoid in 2018".

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 during the Paleolithic era.[1] There are different variants of the diet; some are predominantly plant-based but the most recent popular variants focus on animal products.[2] 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.[3] The ideas behind the diet can be traced to primitive diets advocated in 19th century. In the 1970s Walter L. Voegtlin popularized a meat-centric "Stone Age" diet, and in the 21st century, the Paleo Diet was popularized in the best-selling books of Loren Cordain.[4] As of 2019 the paleo diet industry was worth approximately US$500 million. In the 21st century, the sequencing of the human genome and DNA analysis of the remains of early humans has found evidence that humans evolved rapidly in response to changing diet. This evidence undermines a core premise of the paleolithic diet, that human digestion has remained essentially unchanged over time.[5] Anthropological science has found that the paleolithic human diet was more varied and less meat-centric than had been assumed. The paleolithic diet is promoted as a way of improving health.[6] There is some evidence that following it may lead to improvements in body composition and metabolism compared with the typical Western diet[7] or compared with diets recommended by some European nutritional guidelines.[8] 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
