Evidence category: Systematic review. This describes the source category, not approval or certainty.
Regulatory statement in source: Not separately recorded; do not infer approval from the evidence category.
The carnivore diet is an almost entirely animal-based way of eating. A scoping review found only nine human studies, with small samples, short durations and weak designs. Some reported weight loss, more satiety and better inflammatory or metabolic markers, while risks included possible shortfalls in vitamins C and D, calcium, magnesium, iodine and fibre, and raised LDL and total cholesterol. One case described worsening health. The review concluded that the quality of evidence is very limited.
Benefits reported in the imported source
- Some of the nine human studies reported weight loss, more satiety and better metabolic markers.
- Survey respondents reported better digestion, mood and cognition, all self-reported.
Risks and limits
- A scoping review found only nine small, short, weakly designed studies and called the evidence very limited.
- Reported harms include raised LDL and total cholesterol.
- Possible shortfalls in vitamins C and D, calcium, magnesium, iodine and fibre; one case worsened.
Source bottom line: Carnivore eating has very limited human evidence, with reported weight loss set against raised cholesterol.
Uncertainty: Reference information only. Not medical advice.
Study protocols — reports, not instructions
about 2,300 people across 9 human studies, from single cases to one survey of 2,029 respondents
- Reported regimen
- predominantly red meat, eggs, dairy and organ meat with plant foods excluded; roughly 70-75% of energy as fat, 25-30% protein, under 5% carbohydrate
- Duration
- 43 days to about 6 years; survey respondents reported a median of 12-14 months
- Reported outcome
- Studies reported weight loss, more satiety and lower inflammatory markers, alongside raised LDL and total cholesterol in 27% and micronutrient shortfalls.
