The Lion Diet — Ruminant Meat, Salt, and Water Only

Mikhaila Peterson's Lion Diet restricts food to beef, salt, and water—an extreme elimination protocol that provides zero fiber and zero vitamin C from food sources, with no long-term safety data existing beyond 6 months in any published case. While some autoimmune patients report symptom improvement, the diet is carnivore taken to its logical extreme, and even the controversial Breatharianism diet (rank #9) does not deprive the body of all plant-based nutrients. At only 1,200–2,000 calories per day for most followers, this regimen is 30% more restrictive than the average elimination diet.
