Resources &
Recommended Reading
Every source, teacher, and rabbit hole worth your time behind The Gut Friendly Lifestyle Guide. Paperback can't hold live links. This page can.
Arrived here without the book? Even better. Nothing below assumes you've read a word of it. This is the map on its own terms... every source open, nothing locked, nothing sold to you.
Start Here.
What follows is a library, not a curriculum. Some of it is brilliant. Some of it is a decade old and still holds. Some of it contradicts other parts of it, which is exactly how a real field looks before the marketing department arrives and sands off the edges.
Read widely. Test on yourself. Keep what works. That's the entire method.
The book this page belongs to. Essential foods, habits, and practices for healing your gut and living with more clarity, energy, and strength. Second edition, paperback and ebook, available in every marketplace.
Get the Book →Long-form essays across all five pillars. Ancestral nutrition, physical sovereignty, stillness, esoteric knowledge, and mental mastery. Free to subscribe. Nothing performative.
Read the Essays →"Taking a suitcase full of old wisdom and unpacking it in a new age."
Foundations & Getting Started
If you're new to animal-based or carnivore eating, start in this group. These are the orientation documents... the "what is this, what do I actually eat, and what happens in week one" material.
The original community FAQ. Plain language, no product attached, written by one of the longest-standing zero carb veterans.
reddit.com/r/zerocarb/wiki/faq Getting StartedA practical breakdown of what actually goes on the plate, plus a free 30 day starter guide. Good first stop for the overwhelmed.
meat.health/knowledge-base/carnivore-diet-what-to-eat Getting StartedA structured starter plan with the common early mistakes named up front. Useful if you want a template rather than a philosophy.
biohackerslab.com/all-meat-diet-plan Master IndexThe single best compiled index of carnivore resources on the internet. Studies, books, podcasts, people. If you only bookmark one link on this page, bookmark this one.
justmeat.co Case StudiesHundreds of first-person recoveries across wildly different health histories. Not evidence in the clinical sense. Evidence in the human sense.
carnivore.diet Science & Practice"Eat meat. Not too little. Mostly fat." One of the sharpest analytical minds in the space on ketogenic carnivore metabolism. Absorbed the former ketotic.org archive.
mostly-fat.comDoctors, Researchers & Clinicians
The people doing the actual clinical and academic work. Read these when you want the mechanism, not the testimonial.
World record holding, steak eating, backflipping carnivore and orthopedic surgeon. The loudest early voice in the modern movement and still one of the most tested.
carnivore.diet/dr-shawn-baker-md Nutritional PsychiatryHarvard-trained psychiatrist on food and mental health. Her work on whether vegetables are necessary is the most rigorous treatment of that question anywhere.
diagnosisdiet.com Clinical ResearchDoctors publishing case studies on reversing autoimmune and chronic conditions with a paleo-ketogenic protocol. Actual clinical documentation, not blog posts.
paleomedicina.com/en PhysicianProtein-to-energy ratio, body recomposition, and the intersection of diet and brief intense resistance training. Dense, visual, unusually practical. Fair warning, the site loads slowly.
tednaiman.com Physician · VideoThe same material without the load time. If his site is crawling for you, start here instead. Short, diagram-heavy, and he does not pad.
youtube.com/@tednaiman ArchaeologyAn archaeologist connecting human nutrition to human evolution across prehistory. This is where the "carnivorous by design" argument gets its hard evidence.
paleostyle.com Deep DivesLong, well-cited explorations of specific carnivore topics. When you want one question answered thoroughly rather than the whole field summarized badly.
kevinstock.ioDeep Reading & Long-Form Blogs
For the men who don't want the summary. Some of these archives have been quiet for years. That does not make them less true... it makes them less noisy.
One of the deepest interview archives with long-term carnivores anywhere. Real people, real timelines, years of follow-up.
zerocarbzen.com Gut HealthEleven of the most common objections answered honestly, including the ones that don't flatter the diet. Fibre, vitamin C, cancer risk, the adaptation trough. For the men whose gut is the whole problem.
guthack.com/lifestyle/carnivore-diet PracticalRecipes, weight management, and day-to-day lifestyle strategy for people already eating this way. Less theory, more Tuesday night.
zerocarbhealth.com Philosophy · EthicsThe ethics of eating animals argued properly by someone who lived inside veganism before leaving it. Start with "The Vegans Have Landed" and "Execution at Happy Farm." He steelmans both sides better than either camp does.
aeon.co/users/rhyssouthan Ancestral NutritionThe intellectual grandfather of the whole ancestral health field. Price's dental and dietary fieldwork from the 1930s still hasn't been meaningfully refuted.
westonaprice.org Podcast ArchiveCarnivore and ketogenic eating applied to actual athletic performance. Informative, unserious in the best way, and a solid back catalogue.
theketogenicathlete.comCommunities & Forums
Where the veterans answer questions for free. Use these for troubleshooting, not for identity. A community is a tool, not a tribe to join.
Active, moderated, and unusually low on nonsense for a subreddit. The wiki alone is worth the visit.
reddit.com/r/zerocarb Facebook GroupThe old guard. Many members with five, ten, and twenty year track records. Ask a question here and someone has already lived the answer.
facebook.com/groups/zioh2 Facebook GroupEnormous, fast moving, and varied. Best for sheer volume of lived experience, weakest on signal-to-noise. Search before you post... your question has been answered forty times.
facebook.com/groups/worldcarnivoretribe Facebook GroupSmaller and more conversational than the Tribe. Better if you want an actual thread with someone rather than a firehose of posts.
facebook.com/groups/carnivorouscommunity Forum · FreeA proper forum, not a feed. Discussion boards, member blogs, weekly livestreams, and an archive you can actually search. Free to join and genuinely active.
carnivoretalk.com ForumThreaded, searchable, and archived properly. Better than a feed when you want to follow one question all the way down.
ketogenicforums.com/c/food/zero-carbSupplements & Products
Short list on purpose. Brand clarity comes from removal, not addition. Nothing appears here that isn't used personally or genuinely respected.
Beef liver, kidney, and heart in one capsule. This is the one on monthly subscription in my own house. Canadian company, no border fees, no affiliate arrangement... just what actually gets taken.
higherhealths.ca Nose to Tail · USDesiccated organ supplementation from grass-fed, regeneratively raised cattle. A dozen targeted formulations. The strongest US-facing option if Canadian shipping isn't your problem.
heartandsoil.co Pillar II · The Iron PathWide toe box, zero drop, and a sole thin enough that the ground tells you something. Your feet have 26 bones each and modern shoes treat them like one. Worn daily.
lemsshoes.comLems Shoes is an affiliate link. If you buy through it, The Primal Kodex may earn a commission at no additional cost to you.
Higher Healths and Heart & Soil are not affiliate links and earn nothing. They're here because they're used and they work.
Nothing appears on this page because it pays. A commission never changes what gets recommended, and a product that isn't personally used doesn't get listed at all. Disclosed in accordance with the Competition Bureau of Canada's guidance on influencer marketing and the US FTC's Endorsement Guides.

The Book Was
the Beginning.
The Gut Friendly Lifestyle Guide gave you the map. The Subtraction Kodex goes considerably further... into what has to come out before anything you add will hold.
