How to do the 72-hour bone broth fast

4 min read

According to research, extended fasting can trigger a cellular repair process known as autophagy, which is intensified during a 72-hour period. Learning how to do the 72-hour bone broth fast provides a modified approach that supports your body with essential nutrients, making the extended fast more manageable and effective.

Quick Summary

An extended liquid-only regimen involving nutrient-rich bone broth over three days. This modified fast offers cellular renewal, gut support, and enhanced energy without the severity of a water-only fast. Strategic preparation and gradual reintroduction of food are key.

Key Points

  • Prepare Adequately: Transitioning to a whole-foods diet and reducing processed foods a few days prior is essential for managing withdrawal symptoms.

  • Consume 5-8 Cups Daily: Drink 5-8 cups of high-quality bone broth throughout the day to provide essential nutrients and manage hunger.

  • Stay Hydrated: Supplement bone broth with plenty of water and caffeine-free herbal teas to maintain hydration and electrolyte balance.

  • Anticipate the Phases: Expect hunger pangs on Day 1, a shift to fat-burning (ketosis) on Day 2 with increased clarity, and cellular regeneration on Day 3.

  • Break the Fast Gently: Reintroduce food slowly with small portions of soft, digestible foods like bone broth, cooked vegetables, and fermented foods to avoid digestive shock.

  • Listen to Your Body: Pay close attention to how you feel and stop the fast if you experience severe symptoms like intense weakness or dizziness.

  • Source High-Quality Broth: Use homemade broth from grass-fed bones or a reputable store-bought brand to ensure maximum nutrient density.

Preparing for Your 72-Hour Bone Broth Fast

Preparation is crucial for a successful and safe fast. A few days before you begin, shift your diet to focus on whole, easily digestible foods like lean proteins and vegetables. Minimize or eliminate processed foods, refined sugars, and carbohydrates to help reduce potential withdrawal symptoms during the fast, such as headaches and fatigue.

Essential Supplies to Gather

  • High-Quality Bone Broth: You will need enough to consume 5-8 cups (2-3 quarts) per day. This can be homemade or a reputable store-bought brand made from grass-fed or organic bones.
  • Hydration Aids: Stock up on filtered water, herbal teas (caffeine-free), and mineralized water to supplement your broth intake and support hydration.
  • Optional Boosters: Keep fresh lemon or lime juice, a quality sea salt, and some herbal spices on hand to add variety and electrolytes to your broth.
  • Relaxation Tools: Plan for low-stress activities like reading, light walking, or warm baths to help you manage the physical and mental aspects of fasting.

The 72-Hour Fasting Protocol: Day by Day

This 72-hour process gives your digestive system a complete rest while providing valuable nutrients and protein to maintain energy levels and prevent dehydration.

Day 1: Transition and Adaptation

  • Morning: Start your day with a warm cup of bone broth. This begins the process gently. You may feel a mix of excitement and mild hunger. Sip broth every 2-3 hours.
  • Afternoon: Hunger pangs may peak as your body adjusts to the lack of solid food. Drink extra water or herbal tea between broth servings. A pinch of sea salt in your water can help with electrolyte balance.
  • Evening: Enjoy a final cup of bone broth. Fatigue may set in, so plan for a restful evening. Gentle yoga or meditation can help reduce stress.

Day 2: Peak Autophagy and Ketosis

  • Morning: Energy levels may improve as your body shifts from using glucose to burning fat for fuel, a state known as ketosis. This is when autophagy, the cellular cleanup process, intensifies.
  • Mid-day: Continue sipping broth and staying hydrated. Mental clarity and focus often improve as the body adapts. You might notice heightened senses, including smell.
  • Evening: Hunger typically decreases. Focus on resting and listening to your body's signals. Avoid strenuous activity.

Day 3: Regeneration and Completion

  • Morning: A sense of calm and clarity is common. The body is in a deep regenerative state. The hard work is largely over.
  • Afternoon: Continue with your bone broth and hydration schedule. This is a good time for light activities and reflection. You may notice improvements in joint comfort or skin texture.
  • Evening: Congratulate yourself on completing the fast. Plan your first meal for the next morning. Do not eat just yet.

Comparison: Bone Broth Fast vs. Other Fasting Methods

Feature Bone Broth Fast Water Fast Juice Fast Intermittent Fasting (16:8)
Nutrient Intake Provides collagen, amino acids, minerals, electrolytes. Provides zero nutrients, only water. High in vitamins but also high in sugar, lacks fiber. Varies by eating window, depends on food choices.
Energy Levels Generally moderate and sustained, less fatigue. Often accompanied by fatigue and electrolyte imbalance. Initial energy boost followed by potential crashes from sugar spikes. Depends on meal quality during eating window.
Hunger Management Protein and gelatin help curb appetite, making it more manageable. Can lead to intense hunger and cravings. Can trigger intense cravings, especially for solid foods. Can be managed by adhering to a consistent eating schedule.
Gut Impact Gut-soothing, aids in healing the intestinal lining. Full digestive rest, but can be harsh without nutrients. May cause blood sugar issues and provide little fiber. Depends heavily on food choices during eating window.
Sustainability Often more sustainable for first-timers or those seeking a gentler approach. Challenging and can be difficult to sustain for extended periods. High sugar content can make adherence difficult. Highly sustainable and can be a long-term lifestyle choice.

Breaking Your 72-Hour Fast Safely

The process of reintroducing food is just as important as the fast itself to avoid digestive shock and negative health outcomes. Start with small, easily digestible meals and gradually increase your portion sizes and food variety over the next couple of days.

  • Immediately Post-Fast (Day 4 - Morning): Break your fast with a small cup of bone broth to ease your stomach back into digestion. Wait 30-60 minutes.
  • First Meal (Day 4 - Lunch): Eat a small portion of soft, cooked vegetables or a probiotic-rich fermented food like yogurt or kefir to reintroduce beneficial bacteria.
  • Subsequent Meals: For the rest of Day 4 and Day 5, gradually add small amounts of lean protein and healthy fats. Avoid refined carbs, sugar, and large meals.

Conclusion

Undertaking a 72-hour bone broth fast is a structured, intentional process that can support gut health, cellular repair, and metabolic wellness. By carefully preparing beforehand, managing the fast with sufficient hydration and quality broth, and breaking it gently, you can maximize the benefits while minimizing risks. This guided approach offers a more comfortable and sustainable alternative to a water-only fast, providing your body with the nutrients it needs to thrive during a deep restorative process. Remember to always consult with a healthcare professional before beginning any extended fast, especially if you have pre-existing health conditions.

Headaches can be caused by dehydration or caffeine withdrawal. Ensure you are drinking enough fluids and consider reducing caffeine intake gradually in the days leading up to your fast.

Autophagy is the body's natural process of cellular cleanup, where damaged cells are removed. This process begins within the first 24 hours and is thought to peak between 48-72 hours of fasting.

Yes, you can add a pinch of high-quality sea salt, a squeeze of fresh lemon or lime, or simple, non-caloric herbs and spices like ginger or turmeric to enhance flavor.
