What happens if you cut out every plant food and eat nothing but meat, fish, and eggs? That's the question carnivore answers in practice, not theory — it's the most restrictive eating pattern in mainstream discussion right now, with vegetables, fruit, grains, and legumes excluded entirely. It's an extreme version of a broader low-carb trend, and it draws strong opinions in both directions.
What It Actually Involves
A typical carnivore plate is simply meat, sometimes with eggs or dairy included depending on the version being followed. There's no counting of carbs because there essentially aren't any left to count — the entire plant kingdom is off the table.
Who It Tends to Work For
A relatively small subset of people, often those who have already tried multiple elimination diets and report symptom relief specifically from removing plant foods. It is not something most people jump straight into — most who try it have already gone through less extreme versions like keto or paleo first.
Pros
- Extremely simple — there are no food-combining decisions to make
- Some people report reduced digestive symptoms during the elimination phase
- No calorie counting or macro tracking required
Cons
- The most restrictive and least long-term-studied diet in mainstream use today
- Zero dietary fiber and no plant micronutrients, antioxidants, or polyphenols
- Can be expensive and logistically difficult to sustain, especially when eating out
- Not well suited to try without first discussing it with a doctor, given how extreme the elimination is
Cutting out all plants means cutting out nutrition altogether — that eating only animal products leaves the body with nothing to run on.
Carnivore does cover protein and fat, but it genuinely lacks dietary fiber and the vitamin C and plant micronutrients that normally come from fruit and vegetables — which is exactly why vitamin C, magnesium, and a general multivitamin show up below as the supplements most commonly paired with it.
⚠️ This is the most restrictive diet on our site's list. Cutting out every plant food is a major physiological change. Talk to a doctor before attempting it, and consider working with one throughout, especially if you have any pre-existing condition.
Supplements Commonly Paired With Carnivore
- Vitamin C — normally supplied by fruit and vegetables, genuinely hard to replace on this diet
- Magnesium — supports the electrolyte shifts common to any very low-carb diet
- A general multivitamin — as a broad safety net given the lack of plant-derived micronutrients
- Fiber — some people reintroduce a fiber supplement even while staying otherwise strict
