Diet protocol
Carnivore
Carnivore is the most restrictive diet on this list — only animal products are eaten. No vegetables, no fruit, no grains, no legumes. Some practitioners include dairy; strict carnivores exclude it too.
The research base is thin compared to other diets. Anecdotal reports are strong from a vocal community. We track it because users ask for it.
