What is the carnivore diet?

Meat, eggs, animal fat. No plants. That's the whole definition. The variations come from how strict you are about edge cases.

The carnivore diet is an eating pattern that excludes all plant foods. The whole list. Vegetables, fruit, grains, legumes, nuts, seeds, and oils made from any of them. What remains is meat, eggs, animal fat, and depending on how strict you are, dairy.

That is the entire definition. The variations come from how you handle the edge cases.

What you eat

  • Beef, lamb, pork, chicken, fish, game, organ meats
  • Eggs
  • Animal fats: tallow, lard, butter, ghee
  • Salt
  • Water

Some practitioners also include, depending on where they sit on the strictness spectrum:

  • Dairy (butter, cream, hard cheese, yoghurt)
  • Raw honey and seasonal fruit
  • Coffee and tea (excluded on Lion Diet, generally allowed otherwise)

What you don't eat

Everything plant. The list of surprises for new people:

  • Olive oil and other seed or vegetable oils. They are plants.
  • Black pepper and spices. Also plants.
  • Wine, beer, spirits. Fermented plants.
  • Soy, gluten, MSG, plant-based protein powders.

Why people do it

The most common reasons people land here:

  • Autoimmune conditions that did not respond to other interventions
  • Long-running gut issues (IBS, IBD, food intolerances)
  • Weight regulation and metabolic health
  • Mental health changes (depression, anxiety). Anecdotal but persistent.
  • Energy and athletic performance

What the evidence actually says is a longer story. The honest version is at Why it works (and what we don't know yet).

The strictness spectrum

"Carnivore" is an umbrella term. It covers four practical levels, ordered from most restrictive to least:

  1. 01Lion Diet. Ruminant meat (beef, lamb), salt, water. Nothing else. The strictest named protocol, popularised by Mikhaila Peterson. Used for 30 to 90 days as an aggressive elimination tool, usually for severe autoimmune or gut issues.
  2. 02Strict Carnivore. All meat (ruminant, pork, poultry, fish, game), eggs, animal fats, salt, water. No dairy. No plants. Where most people start if they do not need Lion-level restriction.
  3. 03Carnivore + Dairy. Strict carnivore plus butter, cream, hard cheese and sometimes yoghurt. The long-term default for most practitioners. Adds caloric and culinary flexibility without breaking the meat-first principle.
  4. 04Animal-Based. Carnivore plus raw honey, seasonal fruit and heavy organ-meat emphasis. Sometimes raw dairy. Less an elimination protocol than an ancestral-eating frame. Popularised by Paul Saladino.

Full breakdown at Variations of the diet.

What it isn't

  • Not a weight-loss gimmick. Most people lose weight on it, but the ones who stick with it long-term usually came for something else.
  • Not high-protein. The macro split is fat-dominant. Typically 70 to 80% of calories from fat, 20 to 30% from protein.
  • Not necessarily expensive. Beef mince, eggs, and pork belly are some of the cheapest protein-per-dollar options in the supermarket.
  • Not a religion. Skepticism is welcome here.

What we don't know yet

  • Long-term health effects over decades have not been studied in a controlled setting. Most current evidence is observational, anecdotal, or short-term.
  • The mechanism behind reported mental health changes is unclear. Several hypotheses are on the table (lower inflammation, stable blood sugar, removal of plant antinutrients) but there is no consensus.
  • How well it works for everyone is unknown. Self-selection in published success stories is real.
