Complete Guide to Ancestral Eating

How eating like our great-grandparents. real meat, wild fish, seasonal fruit, and zero seed oils. changed the way we think about food.

A plate of grilled meat with roasted potatoes and peppers

We didn’t plan to start eating this way. It happened slowly; one podcast about seed oils led to a deep dive on ancestral diets, and before we knew it, our pantry looked like a time capsule from 1920.

No canola oil. No ultra-processed cereal. Just meat, fish, eggs, vegetables, seasonal fruit, and the occasional organ meat that took some getting used to (more on that later).

This guide is everything we’ve learned after two years of eating this way. It’s not a dogma. It’s a framework that works for us. and based on the research, it works for most human bodies.

What Is Ancestral Eating?

Ancestral eating is loosely based on the premise that our bodies are optimized for the foods humans ate for the vast majority of our evolutionary history. That means:

  • Animal proteins. Meat, fish, eggs, shellfish. the nutrient-dense backbone of every traditional diet we could find, from the Inuit to Mediterranean cultures
  • Healthy fats. Butter, ghee, tallow, olive oil, coconut oil. not the industrial seed oils that entered our food supply less than a century ago
  • Seasonal produce. Vegetables and fruits that actually grow near you, in season
  • Fermented foods. Sauerkraut, kimchi, yogurt, kefir. gut health before “gut health” became a marketing buzzword
  • Organ meats. Liver, heart, kidney. the parts our ancestors prized but modern culture forgot

What it’s not. a rigid Paleo rulebook. We’re not re-enacting caveman life. We eat white rice sometimes. We enjoy cheese. The point is focusing on nutrient density and removing the foods that didn’t exist 150 years ago.

Seed oils, as a label habit

Reading ingredient labels is the change most versions of this pattern start with. Canola oil, soybean oil, sunflower oil, and safflower oil show up in salad dressings, crackers, restaurant cooking, and plenty of foods sold as healthy.

The practical objections people raise are about processing and use, not a personal before-and-after:

  1. Highly processed. Many are extracted with solvents, then bleached and deodorized
  2. High in omega-6 fatty acids. Excess relative to omega-3 is the usual concern in this literature, and it is still debated
  3. Unstable at high heat. They oxidize more readily than more saturated cooking fats

A common swap is butter, ghee, or tallow for high heat, and olive oil raw or at low temperatures. That is a cooking choice. It is not a Rooted Glow result. Bloating and skin changes after a diet swap are anecdotes unless a study measured them. This page does not have that study. For the research framing, see what the research says about seed oils.

Building Your Plate

A simple plate, if you want a pattern to copy. It is a template, not a log of what anyone here ate.

Protein First

Every meal starts with a protein source. This isn’t about bodybuilding; it’s about satiety, stable blood sugar, and getting the amino acids your body needs.

  • Breakfast. 3 eggs cooked in butter, maybe with smoked salmon or leftover ground beef
  • Lunch. Grilled chicken thighs, sardines on sourdough, or a big salad with steak strips
  • Dinner. Wild-caught salmon, grass-fed ribeye, slow-cooked lamb shoulder, or pork chops

Add Seasonal Vegetables

We don’t count portions. We just fill the rest of the plate with whatever looks good at the farmers market:

  • Spring: asparagus, radishes, peas, spring onions
  • Summer: tomatoes, peppers, zucchini, cucumbers
  • Autumn: squash, sweet potatoes, mushrooms, kale
  • Winter: root vegetables, cabbage, Brussels sprouts, leeks

Healthy Fats

Fat isn’t the enemy; it makes food taste incredible and helps you absorb fat-soluble vitamins (A, D, E, K).

  • Cook in butter or ghee
  • Dress salads with extra-virgin olive oil
  • Eat the skin on your chicken
  • Don’t trim the fat off your steak

Fruit as Dessert

Seasonal fruit replaced our sugar cravings within about three weeks. A bowl of ripe summer berries hits differently when you haven’t had a candy bar in a month.

The Organ Meat Question

Let’s be honest: eating liver for the first time was a mental hurdle. The texture, the idea of it; it took some convincing.

But here’s the thing: liver is the most nutrient-dense food on the planet. A small serving of beef liver gives you more vitamin A, B12, copper, and folate than almost any supplement.

How we eased into it:

  1. Liver pate. blend cooked chicken livers with butter, garlic, and herbs. Spread on sourdough. Actually delicious.
  2. Frozen liver pills. cut raw liver into tiny pieces, freeze, swallow like supplements. Sounds weird. Works.
  3. Mixed into ground beef. grate frozen liver into ground beef when making burgers or meatballs. You won’t taste it.

Heart is honestly the easiest organ to start with. Beef heart tastes like a lean, slightly minerally steak. Slice it thin, marinate, grill. Most people can’t tell the difference.

What About Carbs?

We’re not anti-carb. We’re anti-garbage-carb.

White rice, sweet potatoes, potatoes, sourdough bread, seasonal fruit; these are all fine in our framework. What we removed:

  • Breakfast cereals (highly processed, loaded with sugar and seed oils)
  • Most bread from grocery stores (preservatives, seed oils, dough conditioners)
  • Pasta made from refined wheat (occasionally we’ll have good-quality pasta)
  • Anything with high-fructose corn syrup

The shift here is from processed carbs to whole-food carbs. Your body handles them completely differently.

A sample week

This is an example menu, not a diary from a Rooted Glow writer and not a prescription:

Monday. Eggs and sausage for breakfast. Leftover roast chicken salad for lunch. Salmon with roasted sweet potato and broccoli for dinner.

Tuesday. Greek yogurt with berries and honey. Steak and arugula wrap (sourdough) for lunch. Slow-cooker bone broth soup with root vegetables for dinner.

Wednesday. Scrambled eggs with smoked salmon. Sardines on toast with olive oil and lemon for lunch. Lamb chops with mashed potatoes (butter, not margarine) and sauteed greens for dinner.

Thursday. Liver pate on sourdough for breakfast (it grows on you). Big salad with grilled chicken for lunch. Pork chops with sauerkraut and roasted beets for dinner.

Friday. Bacon and eggs. Tuna salad (olive oil mayo) for lunch. Homemade burgers (with grated liver mixed in) on sourdough buns, side of coleslaw for dinner.

Weekend. Farmers market haul determines the menu. Usually involves a bigger roast (whole chicken, pork shoulder, or beef brisket) that becomes leftovers for early next week.

Getting Started

You don’t need to overhaul a diet overnight. A practical order, if you want one:

  1. Swap your cooking oils. get rid of canola and vegetable oil. Buy butter, ghee, and a good olive oil. This single change takes five minutes and affects every meal.
  2. Read ingredient labels. just start noticing how many packaged foods contain seed oils, sugar, and ingredients you can’t pronounce.
  3. Eat more eggs. they’re cheap, fast, and packed with nutrients. Three eggs for breakfast keeps you full until lunch. Hard-boiled eggs also work as an afternoon snack when focus dips. The portable versions, including eggs, are in 10 brain snacks.
  4. Buy one thing from a farmers market. seasonal, local produce tastes better and is usually cheaper than you’d think.
  5. Try one organ meat. liver pate is the friendliest entry point. Give it three tries before you decide.

The rest happens naturally. Once you start eating real food, the processed stuff starts tasting like what it is: engineered to be addictive, not nourishing.

Frequently Asked Questions

What is ancestral eating?

Ancestral eating is a dietary approach focused on whole, minimally processed foods that humans have eaten for thousands of years: meat, fish, eggs, vegetables, fruits, nuts, seeds, and fermented foods. It eliminates modern processed foods, refined seed oils, and excess sugar that our bodies aren’t designed to handle.

Is ancestral eating the same as paleo?

They overlap significantly but aren’t identical. Paleo strictly eliminates all grains, legumes, and dairy. Ancestral eating is more flexible. It focuses on food quality and processing level rather than strict food group elimination. Some ancestral eaters include properly prepared grains, soaked legumes, and raw dairy if they tolerate them well.

How quickly will I see results from changing my diet?

Most people notice improved energy and digestion within 1-2 weeks. Skin improvements typically appear at the 4-8 week mark as your gut microbiome shifts and inflammation decreases. Body composition changes usually take 2-3 months of consistent eating. The key is consistency over perfection.

Is ancestral eating expensive?

It doesn’t have to be. Eggs, canned sardines, seasonal vegetables, butter, and organ meats are among the most nutrient-dense and affordable foods available. Buying in bulk, shopping seasonally, and cooking at home keeps costs comparable to a standard grocery budget. The savings from cutting processed snacks and takeout often offset the cost of higher-quality ingredients.
