Low-Carb
Carnivore Diet
Only animal-sourced foods, no carbohydrates; an extreme form of low-carb.
The carnivore diet is an extreme form of low-carb: it almost completely eliminates plant foods and is based exclusively on animal products — meat, fish, eggs and, in some variants, dairy. It removes carbohydrates from the diet entirely.
It is a highly controversial diet. It appeals through simplicity and satiety, but eliminates fibre and a range of plant-derived nutrients, with high saturated fat intake and little long-term evidence. We include it here for completeness — it is not an approach to recommend without medical supervision.
History and origin
The first systematic observations about a diet based exclusively on animal products came from explorers who lived among Arctic peoples. Vilhjalmur Stefansson, a Canadian-American anthropologist, spent years on his expeditions (1906–1918) eating exclusively meat and fat alongside the Inuit and returned in good health. In 1928, together with a colleague, he participated in a one-year controlled experiment in New York, eating only meat under medical supervision, without suffering any manifest deficiencies. The study was published and fuelled debates that continue today.
In the modern era, the carnivore diet was popularised mainly through non-academic channels. Shawn Baker, an American orthopaedic surgeon, published Carnivore Diet in 2019 and built a significant online community around his ideas. Canadian philosopher Jordan Peterson contributed to the diet’s notoriety after publicly recounting improvements in his health following the adoption of a strict carnivore regimen. These personal testimonials generated considerable interest but do not constitute clinical evidence.
Controlled long-term studies on the carnivore diet are almost completely absent from the peer-reviewed literature. A few observational analyses and surveys of followers have been published recently, but small sample sizes and non-randomised designs limit the conclusions. The medical and nutritional community remains sceptical about the long-term safety and sustainability of a regimen that completely eliminates fibre and plant foods.

Întrebări frecvente
Is the carnivore diet healthy?
It is highly controversial. It eliminates entire food groups and fibre, with high saturated fat intake, and long-term evidence is very limited. Not recommended without medical supervision.
Do you lose weight on the carnivore diet?
Many people lose weight short-term through the elimination of carbohydrates and the high satiety of protein, which reduces caloric intake. Long-term sustainability and safety remain debatable.
