Do Fasting For Fear-Related Disorder

author avatar Dr. Eric Berg 02/18/2025

Have you explored various anxiety treatments without finding relief? It's common to feel frustrated when you're seeking solutions yet hesitant to try something new like fasting. Let's break down how to utilize fasting to ease anxiety.

Fear is a natural, protective emotion. However, constant fear impacts your health. We'll discuss how fasting can help regain control and reduce anxiety.

The Fear Factor: How Anxiety Affects Your Body

Fear is a crucial survival mechanism. Constant worry strains your body. What does that mean for you?

Your system remains in a fight-or-flight mode. This has numerous undesirable effects. Chronic anxiety significantly affects your adrenal glands and increases stress hormones.

The Amygdala and the Sympathetic Nervous System

The amygdala is a brain area involved in processing fear. It functions as your brain's alarm system. If the amygdala becomes overactive, it keeps you in a heightened state of alertness.

The sympathetic nervous system readies your body for rapid action. While beneficial in emergencies, continuous stimulation results in adrenal fatigue. This will ultimately lead to more anxiety.

Fasting for Anxiety: A Way Forward

What if there's a way to regain some control? Intermittent fasting is a tool worth exploring. Though it might sound intimidating, the benefits for both brain and body are substantial.

Fasting affects various body systems. It promotes cognitive function and improves your mood. It helps manage fear by enhancing the performance of the adrenal glands.

Fasting, Mood, and Neurotransmitters

How does fasting actually help a stressed-out mind? It works by altering essential brain chemicals. Fasting not only alleviates symptoms but also improves your overall mood.

Fasting increases GABA, a neurotransmitter that induces calmness. It elevates dopamine, a feel-good neurotransmitter. NIH research indicates that fasting decreases cortisol, diminishing the fight-or-flight response.

The Science Supporting Intermittent Fasting and Anxiety Relief

What's the scientific perspective? Several studies connect fasting with mental wellness improvements. Fasting is becoming a popular treatment for Generalized Anxiety Disorder (GAD).

Mount Sinai studies reveal that fasting lowers body inflammation, influencing mood and mental health. Evidence suggests fasting may encourage new brain cell growth.

National Institute of Health studies have also shown that fasting lowers oxidative damage. Fasting supports gut wellness. This has connections to your anxiety levels. The gut-brain axis plays a critical role in overall mental health.

Mechanism

Effect of Fasting on Anxiety

Inflammation Reduction

Reduces body-wide inflammation, contributing to better mood and potentially lessening anxiety symptoms.

Brain Cell Growth

Promotes the creation of new brain cells.

Oxidative Stress

Reduces oxidative stress, potentially protecting brain cells.

Gut Health Improvement

Enhances the gut microbiome, supporting a connection to mental well-being.


How to Begin Fasting for Anxiety Relief

Starting requires a gradual approach. Think about what is both practical and effective to achieve. The goal of reduced stress responses, including panic attacks, is achievable.

Intermittent fasting is an excellent starting point. You do not need major immediate dietary changes. Transitioning to a ketogenic diet is more manageable.

Listen to your body and only eat when you feel hungry. Try a two-meal-a-day structure. No snacks in-between to encourage around 18 hours of fasting, this can spark significant changes, promoting physiological shifts and overall well-being.

Enhancing Your Fast: What Helps

Consider the foods you consume during non-fasting periods. Think about supplements that can enhance your fasting benefits. These will contribute to healthy stress levels.

MCT oil helps with brain health and energy. Consider nutritional yeast, which provides B vitamins that are essential for your nerve health. A healthy nervous system will do wonders for promoting mental health.

Increasing fat intake improves satiety. This allows for longer fasting periods. Proper routine encourages calmness, addressing issues like PTSD.

Potential Cautions with Fasting

While fasting has potential benefits, awareness of potential downsides is critical. Safe use is essential. Healthy lifestyle behaviors are crucial.

Consulting a healthcare professional before beginning is crucial, especially if you have health conditions. Discuss any medications with your doctor to prevent complications. Those with eating disorders need special consideration.

Introduce fasting gradually, allowing the body to adjust. Observe and adapt your method as you go. Track your progress, so you can adjust your approach to maximize benefits and reduce anxiety triggers.

Supporting Mental Clarity Through Smart Nutrient Timing

Fasting has shown promise in reducing anxiety by regulating blood sugar levels, promoting brain-derived neurotrophic factor (BDNF), and reducing inflammation.

However, some individuals experience restlessness or disrupted sleep during fasting periods, which can negatively impact mental well-being. To combat this, incorporating certain healthy fats can support brain function and promote relaxation.

For example, taking MCT oil before bed has been reported to help some people feel more satiated and experience improved sleep quality.

MCT oil rapidly converts into ketones, which serve as an efficient fuel source for the brain. This steady energy supply can reduce nighttime awakenings caused by fluctuating glucose levels, helping to promote a calmer state of mind.

When paired with a nutrient-dense keto diet and proper hydration, this simple strategy can make fasting more effective and less stressful, contributing to better mental resilience over time.

Conclusion

Dealing with anxiety requires us to understand our body's responses. Fasting offers a valuable strategy for reducing the effects of anxiety disorders. A technique for grounding may provide some relief as well.

Prolonged worry reduces the quality of life. Strategic fasting, especially with a ketogenic diet, has profound effects. These will aid with Social Anxiety Disorder (SAD).

Fasting boosts neurotransmitters and reduces stress hormones. It’s an excellent addition to wellness strategies. Focus on safety and consider a comprehensive approach.
