• What You Eat: Ruminant meats (beef, lamb), poultry, fish, eggs, organ meats, animal fats (tallow, butter), and occasionally small amounts of hard dairy. Zero fruits, vegetables, grains, seeds, or legumes are allowed.

  • The Pros: Functions as an ultimate elimination diet. Many users report dramatic relief from chronic autoimmune symptoms, severe digestive bloating, and craving spikes.

  • The Drawbacks: Total lack of dietary fiber, potential micronutrient gaps (unless organ meats are regularly consumed), high saturated fat impact on lipid profiles, and very limited long-term clinical trial data compared to broader diets.

  • Best For: People dealing with severe food sensitivities or autoimmune issues using it as a temporary elimination tool.
