Tips to Prevent Headaches While Intermittent Fasting

Intermittent fasting has skyrocketed in popularity for its weight loss and health benefits. However, making sudden changes to your daily eating pattern can lead to some unpleasant side effects like headaches.

If you're struggling with headaches when fasting, don't lose hope. With a few smart strategies, you can troubleshoot this common issue while still reaping all the rewards.

What Causes Headaches During Intermittent Fasting?

Headaches typically crop up in the first few weeks of a new fasting routine. This occurs due to factors like:

Caffeine withdrawal
Dehydration
Hunger pangs
Blood sugar changes
Stress and tension

Powering through the discomfort rarely works well with intermittent fasting headaches. Instead, pinpointing the exact triggers behind your headache makes solving the problem much easier.

How to Prevent Headaches While Fasting

Use these pro tips to troubleshoot headaches when intermittent fasting:

#1: Stay Hydrated

Dehydration is a common headache culprit during fasting. Limiting food intake often means lower fluid intake too.

Drink ample water and herbal teas throughout your fast. Try having a glass 20 minutes before meals as well. Thirst signals also diminish with age, so proactively sipping fluids is key.

#2: Manage Caffeine Intake

If you normally drink caffeinated coffee, tea, or soda, going long stretches without it when fasting can trigger headaches.

Try slowly weaning caffeine instead of abruptly stopping when beginning a fasting plan. Drink half-caf or decaf beverages. Going cold turkey on caffeine when fasting can shock your system.

#3: Include Electrolytes

Fasting causes reduced sodium and magnesium intake from food. These essential minerals and electrolytes prevent headaches.

Mix electrolyte supplements into your water while fasting. Broths, coconut water, and zero-calorie electrolyte drinks help too. Getting sufficient electrolytes prevents headaches induced by mineral loss and dehydration.

#4: Break Your Fast Slowly

Spiking blood sugar when breaking a fast can trigger headaches. Your body isn’t accustomed to dealing with food intake after prolonged fasting.

Break your fast gradually with a small snack like nuts or yogurt before eating a full meal. This prevents shocking your system with a sudden influx of food and blood sugar.

#5: Manage Stress

Stress and tension often manifest as headaches. Beginning a new fasting plan can feel stressful until your body adjusts.

Use stress management techniques like meditation, deep breathing, gentle exercise, or enjoyable hobbies to lower anxiety. Adaptogens like ashwagandha in tea, supplements, or tinctures help too.

Should You Stop Intermittent Fasting if You Get Headaches?

Giving up fasting due to headaches is understandable but likely unnecessary. Troubleshooting the root causes behind headaches can prevent them while fasting.

However, if headaches persist for more than two weeks despite preventive strategies, seek medical advice. Rule out underlying issues before continuing intermittent fasting.

When to See a Doctor About Fasting Headaches

Consult your healthcare provider if you experience:

Frequent headaches unrelated to fasting that worsen while fasting
Severe headache pain
Headaches accompanied by fever, stiff neck, nausea/vomiting, speech issues, or visual disturbances
New headache patterns like throbbing pain after age 50

Such symptoms may indicate an underlying neurological issue like migraines, tumor, or stroke. Seek prompt medical care for severe, worsening, or new onset headaches not relieved through lifestyle measures.

The Takeaway - Tackling Headaches While Intermittent Fasting

It’s common to deal with headaches when making dietary changes with intermittent fasting. Pay attention to your unique headache triggers like hunger, caffeine withdrawal, dehydration, blood sugar spikes, electrolyte loss, and high stress.

Stay well hydrated between fasting periods and intake electrolytes. Manage caffeine intake wisely if needed. Break fasts gradually and utilize stress reduction techniques.

Be patient through temporary discomfort - it takes time for bodies to adjust to a new eating routine when starting intermittent fasting. But stick with smart strategies tailored to your unique situation to reap all the rewards.
