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.

Best for
People who tried autoimmune protocols and other elimination diets without success. Should be approached as a short-term elimination, not a permanent pattern.
Research
Limited. Self-reported survey data shows strong satisfaction. Long-term RCTs do not exist.
How CalPilot helps
Track meat servings, types, and fat-to-protein ratios. Photo logging works well — meat photos are easy to recognize. Vitamin C deficiency tracking flagged if intake stays low.
