What Is the Carnivore Flu and How to Get Through It Fast
If you’ve just started the carnivore diet and suddenly feel like you’ve been hit by a truck, don’t panic — you’re probably going through what’s known as the Carnivore Flu. It’s not an actual flu, but it sure can feel like one.
The good news? It’s temporary, it means your body is adjusting, and with the right steps, you’ll be feeling amazing in no time.
What Exactly Is the Carnivore Flu?
The Carnivore Flu refers to a collection of symptoms that can show up during the first few days or weeks after starting the carnivore diet. These symptoms happen as your body switches from running on carbs to running on fat for fuel — a process called ketoadaptation.
Even though our approach includes some fruit, vegetables, and dairy, this shift in macronutrients can still be a shock to your system — especially if you were eating a high-carb Standard American Diet before.
Common Symptoms of Carnivore Flu
- Fatigue and brain fog
- Headaches
- Digestive issues (bloating, constipation, or diarrhea)
- Cravings
- Dizziness or lightheadedness
- Irritability or mood swings
- Trouble sleeping
Sound familiar? You’re not alone. Most people experience at least a few of these symptoms early on.
Why Does It Happen?
When you drastically reduce your carb intake:
- Your body releases stored glycogen (which holds water).
- You lose fluids and electrolytes fast.
- Your gut microbiome begins to shift.
- Hormones rebalance.
The Carnivore Flu is your body recalibrating. Think of it as a reboot — uncomfortable but necessary for your long-term success.
How to Get Through It Fast
1. Prioritize Electrolytes
Loss of sodium, magnesium, and potassium is a big reason you feel off. Add high-quality sea salt to your meals, drink bone broth, or try an electrolyte supplement.
2. Eat Enough Fat
One of the biggest mistakes beginners make is eating too little fat. Don’t just eat lean meats — include fattier cuts like ribeye, bacon, or salmon to help fuel your body.
3. Stay Hydrated (But Not Just With Water)
Plain water isn’t enough. Replenish minerals by adding a pinch of salt or drinking electrolyte-infused water.
4. Rest and Lower Your Stress
Your body is working hard to adapt. Don’t overdo workouts or push yourself — now’s the time for rest, not PRs at the gym.
5. Ease Into It
While some go all-in overnight, others do better with a slower transition. If needed, taper your carbs over a week or two instead of cutting them cold turkey.

How long does the Carnivore Flu last?

Can I avoid it completely?
Not always — but by staying on top of electrolytes and eating enough fat, you can minimize the symptoms.
Is the flu a sign I should stop the diet?
Nope. It’s a sign that your body is adapting. Stick with it — relief (and results) are just around the corner.
Final Thoughts: Don’t Give Up Now
