Feeling tired, foggy, or irritable after starting keto? That’s the infamous keto flu, and while it’s common, it doesn’t have to derail your weight loss journey. In this guide, you’ll discover 5 proven keto flu remedies to help you stay energized, focused, and on track with your goals.
What Is the Keto Flu?
When you reduce carbs dramatically, your body shifts into ketosis, burning fat for fuel instead of glucose. This switch often leads to temporary symptoms like fatigue, headaches, and mood swings — known as the keto flu. Let’s fix that.
1. Keto Flu Remedies: Replenish Electrolytes
The #1 cause of keto flu? Electrolyte loss — especially sodium, potassium, and magnesium.
Quick fixes:
- Add salt to your food (use sea salt or Himalayan salt)
- Sip on bone broth or electrolyte water
- Take a magnesium supplement daily

2. Stay Hydrated (But Smartly)
You lose water rapidly during early keto. Stay ahead of dehydration — but balance it with electrolytes.
- Drink 8–10 cups of water daily
- Add salt to water or drink keto-safe electrolyte mixes
- Avoid overdoing caffeine
3. Eat Enough Fat
Don’t under-eat. Fat is fuel on keto, and not getting enough can worsen symptoms.
Add to your meals:
- Avocados
- Olive oil
- Eggs and cheese
- Fatty fish and nuts

4. Rest and Reduce Stress
Switching fuel sources is a metabolic challenge. Give your body recovery time.
- Sleep 7–9 hours
- Walk or do gentle movement
- Try deep breathing or stretching
5. Trust the Process – It’s Temporary
Keto flu usually lasts 3–7 days. Don’t quit — adjust, hydrate, and power through. The results are worth it.
Bonus: Avoid These Common Mistakes
- Going zero-carb too fast
- Not eating enough fat
- Skipping meals or fasting too soon
- Ignoring electrolytes
- Not tracking food (especially early on)

🙋♀️ What If Keto Flu Lasts Longer Than a Week?
While most people recover within 3 to 7 days, some may feel lingering fatigue if they’re not getting enough electrolytes or fat. If you’ve been following the tips above and still feel off, review your macro intake or consider adding MCT oil or bone broth for a boost. And remember — don’t cut calories too aggressively in the first week.
💬 When to Seek Help
If your symptoms go beyond the usual (like dizziness or nausea that won’t stop), it’s best to speak with a healthcare provider. Keto flu should never feel like a crash — it’s a transition, not a punishment. Listen to your body.
