Why the Carnivore Diet Doesn’t Work Long Term

(And why you don’t need to live on steak to “fix” your health)

There’s always a new diet that promises to be the one. Recently, the carnivore diet has had its moment in the sun: all meat, no plants, no carbs, no fibre, no fun. For a short time, some people genuinely feel better on it — less bloating, fewer decisions, a sense of control.

But long term?

That’s where the wheels come off the steak wagon.

Let’s break down why.

1. It’s a “feel better fast” diet, not a “live better forever” one

Cut out almost everything you normally eat, and you’ll cut out a lot of the food that was causing you issues. You also stop snacking because… well, it’s hard to binge on plain beef mince at 10pm.

This creates the illusion that meat is magical.

What’s really happening?

• You’ve removed ultra-processed foods

• You’ve reduced mindless grazing

• You’ve simplified your meals

• You’re no longer eating foods you may not tolerate well

You could get the same benefits with way less restriction — without deleting entire food groups from your life like a bad ex.

2. Zero fibre sounds great… until your digestive system files a complaint

Fibre isn’t just “nice to have”; it’s a vital nutrient for long-term health.

Your gut microbes rely on plant fibres to:

• Keep your digestion smooth

• Support your immune system

• Produce beneficial compounds (short-chain fatty acids)

• Reduce inflammation

• Support metabolic health

Remove fibre completely and your gut says: “Excuse me NO.”

Long-term, this can lead to constipation, reduced microbial diversity, and increased disease risk.

Your gut doesn’t want a steak-only rave. It’s begging you to invite some vegetables to the party.

3. Variety isn’t a vibe — it’s a biological requirement

Humans evolved to thrive on a wide range of foods. Plants, fruits, grains, legumes, dairy, fish, nuts, seeds, meat. A rainbow of nutrients.

A carnivore diet narrows all that down to:

• Meat

• More meat

• A different flavour of meat

You miss out on:

• Vitamin C

• Folate

• Antioxidants

• Polyphenols

• Fibre

• Potassium

• A thousand plant compounds your body quietly uses without ever thanking you

You can get away with nutrient gaps short-term.

But long-term? Deficiencies start knocking.

4. It overcorrects a real problem

Here’s the truth few diets admit:

People aren’t turning to carnivore because they love extreme restriction.

They’re turning to it because our modern food environment is chaos.

Ultra-processed foods everywhere.

Confusing advice.

Snacks in every drawer.

Stressful eating patterns.

Carnivore feels like a reset button — a hard boundary that takes the chaos away.

But you don’t fix a chaotic relationship with food by swinging to the opposite extreme. You fix it by rebuilding trust, structure, awareness, and habits.

Which is exactly what Scrummy is about.

5. The sustainability problem (aka: no one wants to live like this)

A diet is only as good as your ability to keep doing it — joyfully.

Most people eventually hit one of these walls:

• “I want vegetables back.”

• “I miss fruit.”

• “My digestion hates me.”

• “I can’t live without crunchy things.”

• “I’m tired.”

• “My blood tests are concerning.”

The carnivore diet is a short-term intervention, not a lifestyle.

If you can’t see yourself eating that way in 5 years, it’s not a long-term solution.

6. It teaches restriction, not skill

The real goal of eating well isn’t perfection — it’s capability.

You want to learn how to:

• Handle cravings

• Build meals without fear

• Enjoy treats without spiralling

• Eat out without panic

• Understand how different foods feel in your body

• Create healthy meals that taste good

• Navigate real life

Extreme diets teach you none of that.

When you come off them, you’re right back where you started — just hungrier and a bit confused.

So what does work long term?

A way of eating that:

• Includes foods you enjoy

• Gives you energy

• Supports your digestion

• Fits your lifestyle

• Isn’t built on fear or rules

• Helps you add good habits rather than remove everything you love

You don’t need extremes.

You don’t need to fear plants.

You don’t need to choose between broccoli and beef — you’re allowed to have both on the same plate. Imagine!

Scrummy is all about helping you build a calmer, simpler, saner approach to food — without the drama.
