Will you join me on a little adventure? A trip back in time? Back to a time before the crazy world we live in today.

Before Starbucks, McDonald’s, or Walmart. Even before we had electricity, running water, and toilets.

It’s hard to imagine how we survived, yet this is how humans have lived for the vast majority of their existence. This world of convenience and plenty is actually a novel thing. We’re very lucky, really.

So, let’s imagine living as a hunter-gatherer. The priorities for the day are to avoid being eaten by a sabertooth tiger and to find food for the tribe.

Now imagine, after a grueling day’s hunting, you and your fellow hunters secure a kill. Imagine the relief that tonight, your belly will be full after many nights of emptiness and gurgling.

Do you think, after not knowing where the next meal will come from, that any part of the beast, whose life has been sacrificed to allow yours to live on, will be left to waste?

Surely I don’t need to answer that. It’s safe to assume that whatever can be eaten, will be. Eating nose-to-tail is about as ancestral as it gets.

So, what is nose-to-tail eating? It’s about going back to your roots. It’s about paying respect to the animal that was sacrificed. It’s about accessing all the nutrients and goodness Mother Nature has provided – it’s almost as if we were designed to eat the whole animal.

TL;DR

• Nose-to-tail eating helps you get the full nutrition your body expects from animals, not just the lean cuts.
• Organs, fat, broth, and tougher cuts support energy, recovery, hormones, and digestion in ways typical diets miss.
• This approach matches how our ancestors ate when nothing went to waste and every part had a purpose.
• Adding even small amounts of organs, broth, or beef fat can make a real difference to your daily energy and long-term health.

What Does Nose-to-Tail Eating Actually Mean?

It means eating more than just the lean cuts and using the whole animal for nutrition. In simple terms, it’s a return to how humans always ate before modern food culture narrowed our choices.

Most people today buy the same cuts on repeat: chicken breast, ground beef, and steaks, maybe bacon. But our ancestors didn’t have that luxury. They ate everything because every part offered something different.

Muscle meat gave strength. Organs supplied dense nutrients. Bones provided minerals and collagen. Fat delivered long-lasting energy.

In my own diet, this shift made a big difference. I stopped chasing snacks because real food filled the gaps. The richer nutrient profile helped me feel more stable and focused through the day.

How Is Nose-to-Tail Different From the Way Most People Eat Today?

Most modern diets ignore organs, fat, skin, and connective tissue. These parts often contain the nutrients people struggle to get from supplements.

When you only eat muscle meat, you miss key vitamins, minerals, and compounds like choline, glycine, and retinol. These support energy, recovery, mood, and metabolic health. It’s a more complete approach to nutrition without adding complexity.

Why Should Humans Eat the Whole Animal?

Eating the whole animal gives your body a fuller range of nutrients than muscle meat alone. It creates a more balanced and satisfying way of eating that supports energy, recovery, and long-term health.

When you focus only on lean cuts, you rely on a limited nutrient profile. Organs provide vitamins and minerals in forms your body can use easily. Bones and connective tissue give you collagen and glycine, which support joints, skin, and digestion. Animal fat offers steady fuel without blood sugar swings.

In my own diet, this was the biggest change. I felt more grounded and less hungry through the day. I didn’t need snacks or coffee boosts because the food actually kept me going. It felt like I finally gave my body what it had been missing.

What Are the Main Benefits in Simple Terms?

Here’s the straightforward version:

• Better energy because organs and fat provide nutrients that support cell function.
• Better recovery because collagen-rich parts help joints, tendons, and gut lining.
• Better mood because B vitamins, choline, and animal fats support brain health.
• Better appetite control because real nutrients satisfy the signals your body sends.

Why Does This Matter More Today?

Modern diets are full of processed choices but low in nutrient density. Many people overeat because their body keeps asking for what it never receives. Eating the whole animal solves the gap without complicated rules.

What Nutrients Do You Get From Organ Meats That Muscle Meat Misses?

Organ meats provide vitamins, minerals, and compounds that muscle meat lacks. They offer far higher density and variety, which supports energy, immunity, and overall function.

Muscle meat is great for protein and strength, but organs fill the nutritional gaps. Liver is rich in retinol, B vitamins, copper, and choline. Heart provides CoQ10, which supports energy at a cellular level. Kidneys bring selenium and specific peptides that support detox pathways. Even “odd” organs like spleen or thymus offer unique compounds that you simply cannot get elsewhere in meaningful amounts.

In my own diet, adding small portions of liver, heart, and kidney changed how satisfied I felt. I didn’t need multivitamins because the food covered what supplements were trying to patch.

That said, if you struggle with the thought or taste of organ meats, but want the health benefits, supplements are a great option. There are many on the market; see my round-ups of the best organ meat complex and beef liver supplements to help you figure out which one is best for you.

Spoiler alert: MK Supplements top the list. They’re superior to any other on the market. Use the code JIMJACKSONFB for a 15% discount.

Are Organs Really More Nutrient-Dense?

Yes. In fact, organs often contain 10–50 times more vitamins and minerals than standard cuts.

Here’s a simple comparison to show the difference:

Food (100g)	Vitamin A	B12	Iron	Choline	CoQ10
Beef steak	0 IU	Moderate	Moderate	Low	Low
Beef liver	~16,000 IU	Very high	High	Very high	Moderate
Beef heart	0 IU	High	Moderate	High	High
Beef kidney	Low	High	High	High	Moderate

Which Organs Offer the Biggest Nutritional Return?

Here’s the quick breakdown:

• Liver: Best all-rounder for vitamins A, B12, folate, copper, and choline.
• Heart: Great for CoQ10 and B vitamins.
• Kidney: High in selenium and supports antioxidant pathways.
• Spleen: Rich in heme iron.
• Brain: High in DHA and phospholipids for brain health.
• Tongue: Fatty, satisfying, and rich in B vitamins.
• Bone marrow: Deep energy source due to healthy fats and stem-cell-rich compounds.

Mini Q&A: Simple Organ Questions

Which organ gives the biggest energy boost?

Liver. Its B12 and retinol content support energy production directly.

Which organ is easiest to start with?

Heart. Mild taste and easy to cook.

Do you need large amounts?

No. Small portions deliver big results.

How Does Nose-to-Tail Eating Fit With an Ancestral Diet?

It fits perfectly because humans have always eaten the whole animal for survival and strength. Wasting parts is a modern behaviour, not a natural one.

For most of human history, food was scarce and hunting took effort. When your life depended on an animal, you used everything. Organs gave the most nutrition. Fat kept you warm and fueled long days. Bones became broth. Even connective tissue became valuable because it supported joint health and recovery.

In my own diet, eating this way felt more “human” than any modern rule-based plan. It simplified everything. No counting. No weighing. Just real food with intent.

Would Our Ancestors Have Wasted Any Part of an Animal?

No. Every part had a purpose.

Here’s how a traditional hunt likely looked:

• Organs eaten first for immediate energy.
• Fat saved for cooking or travel.
• Muscle meat shared or dried for later.
• Bones simmered for broth.
• Skin used for tools or clothing.

Nothing went to waste because every part helped the tribe survive. That mindset aligns with basic common sense. If you had to chase dinner for miles, you wouldn’t throw the best bits in the bin.

Why This Ancestral Test Still Matters

Modern health advice often ignores human history. We’re told to fear fat, avoid cholesterol, and prioritise fibre-heavy plants. Yet our ancestors thrived without supermarkets or dietary guidelines.

Nose-to-tail eating reminds us of what actually fueled human evolution. It brings us closer to the foods that built strong bones, sharp minds, and resilient bodies.

What Health Benefits Do People Notice When They Eat Nose-to-Tail?

Most people notice better energy, stronger digestion, and more stable appetite. The fuller nutrient profile supports the body in ways modern diets often miss.

When you give your body organs, fat, collagen, and minerals, you fill nutritional gaps naturally. Many readers tell me they feel more grounded within a week. I felt the same. My energy stopped swinging up and down. I didn’t reach for snacks. Training felt smoother. My legs recovered quicker. Even my focus at work improved because my meals actually fuelled me.

Can It Help With Energy?

Yes. Organ meats and animal fats support energy production directly.

Liver brings B12, folate, and retinol. These support mitochondria—the tiny engines in your cells. Heart offers CoQ10, which helps those engines run efficiently. Fat provides steady fuel without the spikes and crashes you get from carbs.

If you wake tired, hit a mid-afternoon slump, or rely on coffee to get through the day, this way of eating often makes a noticeable difference.

Can It Support Digestion and Recovery?

Yes. Collagen-rich foods help repair the gut lining and support tissue recovery.

Bone broth, slow-cooked cuts, skin, and connective tissue offer glycine, proline, and minerals. These support joint comfort, muscle repair, and smooth digestion. Many people find bloating settles when they add more collagen and reduce processed foods.

In my own diet, swapping cereals and bread for eggs, meat, and broth made digestion predictable again. Heavy meals felt lighter. Recovery from training improved without adding supplements.

Quick Summary: What People Notice First

• Steadier energy through the day.
• Better digestion with less bloating.
• Stronger recovery from workouts.
• Clearer focus and better mood.
• Fewer cravings because meals actually satisfy.

Why Do Animal Fats Matter More Than Most People Think?

Animal fats provide steady fuel, support hormones, and keep you full for longer periods. They work with your biology far better than most modern oils or carb-heavy meals.

Fat has been part of the human diet for as long as humans have existed. It offers slow-burning energy and helps your body absorb fat-soluble vitamins like A, D, E, and K. These vitamins are found naturally in animal foods, not in seed oils or ultra-processed snacks. In my own diet, adding more tallow, butter, marrow, and egg yolks gave me stable energy and better mental focus. I felt less hungry, less irritable, and less dependent on caffeine.

What Happens When You Eat Fat Without Carbs?

Your body switches to fat as its main fuel source. This leads to steadier energy, fewer cravings, and better metabolic control.

When carbs stay low, insulin remains stable. Your body taps into dietary fat and stored fat for fuel. This is why many people feel sharper and more alert when they ditch the carb-fat mix that dominates modern meals.

How Does This Compare to Eating Fat With Carbs?

Eating fat and carbs together sends mixed signals to your metabolism.

Your body always uses glucose first when carbs are present. Fat gets stored rather than burned. This is one reason modern meals—burgers with buns, pizza, pastries, fries—lead to weight gain and sluggish energy. Our ancestors rarely ate these combinations because they didn’t exist.

In my experience, removing the carb-fat combo stabilised everything. No more food comas. No more mid-afternoon fog.

Quick Summary: Why Animal Fats Help

• They provide long-lasting energy.
• They keep hunger controlled.
• They support hormone production.
• They help absorb key vitamins.
• They reduce the blood sugar rollercoaster.

Is Eating Offal Safe, and How Do You Choose Quality Sources?

Yes. Offal is safe when you buy from trusted sources and store and cook it properly. Most concerns come from misunderstanding or poor handling, not the food itself.

Organ meats were a staple for humans long before supermarkets existed. They spoil faster than muscle meat, so freshness matters. Buying from a good butcher, a local farm, or a supplier you trust removes most of the risk. In my own diet, I stick to grass-fed or pasture-raised animals where possible. The taste is better, and the quality feels higher.

Are There Any Organs You Should Avoid?

Most organs are perfectly safe, but a few have caveats.

• Liver: Powerful food but not needed daily due to high vitamin A.
• Bear liver: Avoid completely due to extreme vitamin A levels.
• Brain: Safe if sourced from healthy animals, but avoid from countries with prion-disease concerns.
• Glands (pituitary, adrenal): Niche foods; buy only from trusted farms.

For standard organs like beef liver, heart, kidney, tongue, and spleen, the safety profile is excellent when sourced well.

How Do You Store and Cook Organ Meats Safely?

Organ meats keep well when handled with care.

• Keep refrigerated and use within 1–2 days, or freeze portions.
• Cook thoroughly unless you’re confident in sourcing and preparation.
• Slice and freeze liver into small pieces for easy use.
• Rinse kidneys and soak if you want a milder flavour.

These steps keep things simple and predictable.

Mini Q&A: Safety Basics

Is liver toxic?

Only in extreme amounts. Normal portions are safe and beneficial.

Can you eat organs raw?

Yes, but only with very high-quality sourcing. Most people cook them.

Is kidney safe?

Yes. It filters blood but does not store toxins.

How Can You Start Eating Nose-to-Tail Without Feeling Overwhelmed?

Start small with the mildest cuts and build from there. You don’t need to jump straight into liver or kidneys on day one.

Many people assume nose-to-tail means complicated recipes or strong flavours. It doesn’t. Most organs taste mild when prepared well, especially heart, tongue, and marrow. In my own diet, I added one new cut at a time. This kept it simple and let my taste adapt naturally. Before long, dishes that once felt unusual became normal parts of the week.

What Are the Easiest Ways to Add Organs Into Daily Meals?

You can slip organs into meals without changing your routine.

• Mix a little minced heart into your ground beef.
• Add liver in small amounts to bolognese or chilli.
• Spread bone marrow on steak or mix into mash (if you eat potatoes).
• Slow-cook ox cheek, tongue, or shank until tender.
• Drop a frozen cube of liver into a stew or broth.

Small portions go a long way because organs are so nutrient dense.

What Simple Recipes Help Beginners?

Here are starter ideas that keep the flavour familiar:

• Heart burgers: Replace 20% of mince with heart.
• Liver and onions (light version): Soak liver in milk or lemon, then pan-fry quickly.
• Marrow butter: Mix softened butter and roasted marrow; use like a sauce.
• Bone broth: Toss bones in a slow cooker with water and salt.
• Tongue tacos (or lettuce wraps): Slow-cook tongue, peel, slice, and season.

These dishes feel “normal” but deliver the benefits of nose-to-tail eating without a big leap.

Mini Q&A: Getting Started

What if I dislike the taste?

Start with heart or tongue. They taste like regular beef.

How much liver do I need?

A couple of ounces once or twice a week is plenty.

What if my family won’t eat organs?

Blend small amounts into minced meat dishes. No one notices.

Does Nose-to-Tail Eating Support Better Sustainability?

Yes. Eating the whole animal reduces waste and respects the life taken. It uses resources efficiently and supports more responsible farming.

Most modern meat production prioritises convenience cuts. This leaves organs, fat, bones, and other nutrient-rich parts underused or discarded. When more people choose nose-to-tail, farms can operate with less waste and fewer animals need to be raised to produce the same amount of food.

In my own buying habits, choosing whole cuts or mixed boxes from local farms felt more ethical and more connected to real food.

How Does It Reduce Waste?

Nose-to-tail eating improves sustainability by making use of everything.

• Bones become broth rather than being thrown away.
• Fat becomes cooking fuel instead of factory waste.
• Organs feed families instead of being sent to pet-food factories.
• Connective tissue becomes slow-cooked meals instead of landfill.

Using all edible parts respects the animal and reduces environmental load.

Is It More Ethical Than Standard Meat-Eating?

Many people believe so. Using the whole animal honours the life taken, much like our ancestors did.

Most ethical concerns in meat production stem from waste and industrial farming. Supporting smaller farms, pasture-raised animals, and full-use eating patterns shifts the system toward better treatment and better outcomes. When you buy liver, kidney, bones, and fat, you support farming that values the whole animal—not just a handful of supermarket cuts.

Mini Q&A: Sustainability Basics

Does buying organs cost less?
Usually, yes. They’re often cheaper than steaks but far more nutritious.

Does this reduce my environmental impact?
It lowers waste and supports regenerative farming if you buy from the right sources.

Does it help small farms?
Absolutely. Farms earn more when people buy the whole animal.

What Common Myths Stop People From Trying Nose-to-Tail?

Most people avoid organ meats because of assumptions about taste, safety, and difficulty. These beliefs usually come from unfamiliarity, not reality.

Most of us grew up in a world where supermarkets pushed boneless, skinless cuts as the “normal” choice. Anything outside that narrow band feels odd at first. But once you try a few simple recipes, the fear disappears. In my own diet, I found that most organs taste far milder than expected—especially heart, tongue, and marrow.

The idea that organs are “hard to cook” also fades quickly when you learn one or two basic methods.

Is the Taste Really That Strong?

No. Most organs taste like beef or lamb with a richer flavour.

Heart tastes like lean steak. Tongue becomes tender and mild after slow cooking. Even liver is pleasant in small portions or when mixed with mince. The strong flavour myth comes from overcooking or using very large amounts.

Is It Expensive?

Usually not. Organs are some of the most affordable foods in the butcher’s counter.

Here’s a simple comparison:

Cut	Typical Price	Notes
Ribeye steak	High	Popular cut, expensive per calorie
Beef liver	Very low	10–50x the nutrients for a fraction of the cost
Beef heart	Low	Lean, versatile, high in B vitamins
Bone marrow	Low–moderate	Rich in fat and energy
Beef tongue	Moderate	Large, feeds several people

Eating nose-to-tail often reduces your food bill while increasing nutritional value.

Does It Take More Time?

Not really. Some cuts need slow cooking, but most prep is hands-off.

• Heart and liver: 5–10 minutes in a pan.
• Tongue: Slow cooker does the work.
• Bones: Throw into a pot, leave for hours.
• Marrow: Roast in minutes.

The perceived effort is bigger than the actual effort.

Mini Q&A: Myth Busting

Is offal unsafe?

Not when sourced well and cooked properly.

Will it make my house smell?

No more than cooking any other meat.

Do I need “acquired taste”?

Liver and kidney? Yes, these have unique tastes that many struggle with. Others such as heart and sweetbreads (glands), are very tasty.

What’s the Common-Sense Way to Think About Eating Animals?

The simplest way is to ask what humans would have eaten before modern food systems. If you rely on that question, the confusion disappears.

Before supermarkets and dietary guidelines, people ate what nature provided: meat, fat, organs, bones, and whatever seasonal plants were available. There were no processed oils, no fortified cereals, and no factory-made snacks. When food required effort—hunting, butchering, cooking—you valued every part. That mindset explains why nose-to-tail eating feels so natural when you try it. It aligns with how the human body evolved to function.

In my own experience, this “ancestral filter” cut through more noise than any diet book ever could. It helped me ignore trends and focus on real fuel.

What Would Humans Have Eaten Before Supermarkets and Factory Farms?

They would have eaten the animal in full and used it across several meals.

• Organs for immediate energy.
• Fat for warmth and long-lasting fuel.
• Muscle meat for strength and satiety.
• Bones for broth and minerals.
• Skin and connective tissue for collagen.

Anything seasonal—fruit, honey, or certain vegetables—was a bonus, not the foundation of the diet.

This approach fits our physiology. Our bodies store fat, not fibre. We absorb animal nutrients easily. We thrive on complete proteins and natural fats.

Why Does This Question Matter Today?

Because most modern advice ignores human history.

You’re told to fear cholesterol, eat low-fat snacks, and base meals on grains. Yet our ancestors did none of this. They thrived on dense animal foods because that’s what their environment provided.

When you return to eating patterns grounded in common sense—not marketing—you often feel better quickly. Stronger digestion, steadier energy, clearer mind.

Mini Q&A: The Ancestral Filter

How do I decide if a food is “ancestral”?
Ask if it existed before shops or factories.

Does this mean avoiding all modern foods?
No. It means prioritising foods your biology recognises.

Why does this approach work so well?
It removes confusion and supports natural human physiology.

How Do You Make Nose-to-Tail Eating a Long-Term Habit?

Start with small, repeatable steps rather than dramatic changes. You’ll stick with it when it feels normal and not like a “challenge.”

I kept organ meats in my weekly shop, even when I wasn’t sure how I’d use them. That small shift made it routine. I cooked heart with mince, roasted bones for broth, and added a couple of ounces of liver to meals now and then. Over time, this became automatic. The more I felt the benefits—better recovery, steadier mood—the more it reinforced the habit.

What Simple Mindset Shift Makes It Easier?

Stop thinking of organs as “special foods.” Think of them as part of the animal.

When you view the whole animal as food, the decision becomes straightforward. Some parts provide protein. Some offer vitamins. Some supply fat. Some support joints and digestion. Together, they create a complete diet without extra effort.

Mini Q&A: Building the Habit

How often should I eat organs?
A couple of small servings a week is enough for most people.

Do I need complicated recipes?
No. Simple pan-frying or slow cooking works great.

What if I fall out of routine?
Start again with one small step—add heart or marrow to a single meal.

Conclusion: Why Nose-to-Tail Matters for Health, Energy, and Modern Life

Nose-to-tail eating works because it gives your body what it actually needs. When you eat the whole animal—organs, fat, connective tissue, bones, and muscle—you cover the full spread of human nutrition without relying on supplements or modern “health hacks.”

Most people feel the benefits quickly. Better energy. Stronger digestion. Fewer cravings. More stable mood. It’s not magic. It’s biology. You’re fuelling your body with dense, complete nutrition instead of the stripped-down cuts that dominate supermarket shelves.

In my own life, this approach simplified everything. Food became satisfying again. My energy stopped swinging. My health felt predictable and solid.

And the best part? It aligned with the way humans ate for thousands of years before modern diets confused the picture. It’s what I call the Ultimate Human Diet.

If you want to feel stronger, clearer, and more grounded, starting with the whole animal is a practical step that makes sense. And that brings us back to the core question that guided this entire post:

What would humans have eaten before modern food existed?

Follow that answer, and your health usually follows too.

And that’s it… have a nutritious day!

Mini FAQs: Quick Answers to Common Nose-to-Tail Questions

Most people have the same handful of questions when they first look into nose-to-tail eating. These quick answers keep it simple and practical.

Is Liver Safe to Eat Every Day?

Small amounts are safe, but daily large portions aren’t necessary.

Liver is extremely nutrient-dense, especially in vitamin A. You only need a couple of ounces once or twice a week to get the benefits. In my own diet, I treat liver like a supplement—powerful, but used in sensible amounts.

Which Organs Give You the Most Energy?

Liver and heart offer the strongest energy support.

Liver brings B12, folate, and retinol, which help your cells produce energy. Heart delivers CoQ10, which boosts mitochondrial function. Many people feel a noticeable lift when they include these regularly.

What’s the Best Organ for Beginners?

Heart. It tastes like normal beef and is easy to cook.

You can pan-fry it, dice it into stews, or mix it with mince. Most people can’t tell the difference. Tongue is another easy option when slow-cooked.

Should You Eat Organs Raw?

Only if you trust the source completely.

Most people cook organs because it’s simple, safe, and predictable. If you choose to go raw, quality and handling matter far more.

Can You Freeze Organ Meats?

Yes, and it makes things easier.

Slice liver into small pieces, freeze flat, and drop individual pieces into meals when needed. Hearts, kidneys, and marrow also freeze well.
