Ever wondered what happens if you eat only meat for 30 days? In this video, I react to Dr. Sten Ekberg’s breakdown of the carnivore diet, looking at the science, myths, and the real-world stories behind it. From nutrient concerns to healing autoimmune issues, here’s what the evidence actually shows.

Summary: “What Would Happen If You ONLY Ate Meat for 30 DAYS?”
- Core question: What happens if someone eats only meat for 30 days?
- Framing: Presented as an elimination diet to identify food triggers and reduce inflammation; then optionally reintroduce foods to test tolerance.
Reported/Claimed Effects (from anecdotes and observations described)
- Weight & appetite: Increased satiety, reduced hunger between meals, spontaneous longer gaps between meals; weight-loss plateaus may break.
- Metabolism: Shifts toward low-carb/ketogenic metabolism.
- Inflammation & symptoms: Improvements reported in gut issues, skin issues, inflammatory joint pain, and other autoimmune-type symptoms.
- Mood: Reports of improved mood and reductions in anxiety/depression.
Proposed Rationale (as explained)
- Lower antigen load: Removing many plant foods purportedly reduces immune reactions; less immune activation → less inflammation.
- “Neutral” food claim: Meat is described as the least likely to provoke inflammatory responses compared with many other foods.
- Leaky gut: Low-carb/keto and carnivore patterns are claimed to help “fix leaky gut,” offered as an explanation for improvements in autoimmune problems.
Nutrients & Common Objections
- Vitamin C / scurvy: It’s claimed that people do not develop scurvy on carnivore; explanation given that vitamin C competes with glucose for transport, so with low glucose, vitamin C is used more efficiently. A recent scurvy-related paper is mentioned, but the speaker states they don’t observe scurvy in practice.
- Fiber: The diet is presented as workable without fiber; people with alternating constipation/diarrhea (e.g., IBS) are suggested as potential beneficiaries.
How to Do the 30-Day Trial (as described)
- Foods emphasized: Unlimited meat, poultry, fish, shellfish, and eggs.
- Optional additions (small amounts): Cheese, cream, oils, mayonnaise.
- Stricter start: Some guidance suggests initially removing cream/milk and even certain vegetables; after improvements, consider testing reintroductions.
- Adaptation period: May “feel weird” at first when switching to keto/low-carb metabolism.
After 30 Days
- Reintroduction test: Gradually add small amounts of carbohydrates to find personal tolerance; if symptoms return, remove the triggering items again.
- Longer-term choices: Some people remain strict if all symptoms resolve and return with reintroductions; others maintain a low-carb pattern with selective foods.
Populations Discussed as Possibly Benefiting
- People with IBS-type symptoms (constipation/diarrhea), inflammatory or autoimmune complaints, weight-loss stalls, or suspected food sensitivities.
Evidence Notes (within the video)
- Mentions of a survey of self-described carnivore eaters and a desire for more formal studies comparing carnivore, low-carb, and higher-carb diets.

I really liked how they approached the elimination aspect of the diet, especially introducing fruits and vegetables back in for people who jump straight to carnivore who didn’t actually have some plant-based intolerance. It really illustrates that all on our own journeys figuring out what works for us
