How to do a 72 hour fast with bone broth?

5 min read

Scientific studies show that prolonged fasting can induce cellular repair, known as autophagy, and increase insulin sensitivity. This comprehensive guide explains how to do a 72 hour fast with bone broth as a gentler, more supported alternative to a water-only fast, nourishing your body with essential nutrients as you reset your system.

Quick Summary

A detailed plan for safely completing a three-day fast using nutrient-dense bone broth. This approach provides key electrolytes and protein to sustain energy and manage hunger during the fasting period, while still promoting significant metabolic benefits. Guidance on preparing, executing the fast, and reintroducing food is essential for success.

Key Points

  • Prepare Adequately: Gradually transition to low-carb meals and consult a doctor before starting an extended fast.

  • Consume 5-8 Cups Daily: Drink 2-3.5 liters of high-quality bone broth per day to provide essential electrolytes and nutrients.

  • Stay Hydrated: Supplement bone broth with plenty of water and herbal teas to avoid dehydration and electrolyte imbalance.

  • Re-feed Gently: Break the fast with easily digestible foods like broth, soft vegetables, and lean protein, avoiding heavy or processed meals.

  • Recognize Risks: Watch for signs of electrolyte imbalance, like dizziness and fatigue, and be prepared to end the fast if severe symptoms occur.

A 72-hour modified fast with bone broth is a practice that combines the principles of extended fasting with the nourishing properties of bone broth. Unlike a strict water fast, the inclusion of bone broth provides essential minerals, electrolytes, and amino acids, helping to mitigate some of the common discomforts like headaches, fatigue, and muscle cramps. This approach can be particularly beneficial for gut health due to the high content of collagen and gelatin in bone broth, which can help support the intestinal lining.

Preparing for Your 72-Hour Bone Broth Fast

Preparation is crucial for a successful extended fast. Rushing into it without proper planning can lead to unnecessary discomfort or even adverse effects.

Before You Begin

  • Consult a Professional: It is highly recommended to consult a doctor or registered dietitian before undertaking any prolonged fast, especially if you have underlying health conditions like diabetes, kidney disease, or a history of eating disorders.
  • Ease In: If you are new to fasting, start with shorter durations, such as a 16:8 or 24-hour intermittent fasting protocol, to allow your body to adapt.
  • Plan Your Schedule: Choose a time when your social calendar and work commitments are light. A weekend is often ideal, as it allows for ample rest and minimizes stress.
  • Gather Your Supplies: Stock up on high-quality bone broth (homemade or store-bought), plenty of water, and herbal teas. Optional but recommended are electrolyte supplements or Himalayan sea salt to add to your water.
  • Taper Down: In the days leading up to your fast, transition to a low-carb, whole-foods diet. This helps reduce initial cravings and starts the metabolic shift towards using fat for energy.

Executing the Fast: A Day-by-Day Protocol

Your 72-hour bone broth fast begins after your last meal on Day 0. For example, if your last meal is at 6 p.m. on Friday, your fast will end at 6 p.m. on Monday.

During the Fast

  • Bone Broth Intake: Consume 5 to 8 cups (2-3.5 liters) of bone broth throughout the day. You can space this out as needed, for example, a cup every few hours to manage hunger.
  • Hydration: Drink plenty of plain water and non-caffeinated herbal teas. Adding a pinch of sea salt to your water can help with electrolyte balance.
  • Activity Level: Stick to gentle activities like walking, light stretching, or yoga. Avoid intense, strenuous exercise, as your energy levels will be lower.
  • Listen to Your Body: Pay close attention to how you feel. While some fatigue and hunger are normal, persistent dizziness, irregular heartbeat, or severe weakness are signs to break your fast immediately.

How to Make Homemade Bone Broth for Fasting

Making your own bone broth allows you to control the ingredients and ensure high quality.

Ingredients:

  • 3-4 lbs bones (beef, chicken, or a mix)
  • 1 tbsp apple cider vinegar
  • 1-2 gallons of water
  • Optional: vegetables like carrots, celery, and onion, plus herbs

Instructions:

  1. Roast Bones (Optional): For enhanced flavor, roast beef or chicken bones in the oven at 450°F for 20-40 minutes until lightly browned.
  2. Combine Ingredients: Place bones in a large stockpot or slow cooker. Add apple cider vinegar and cover with water. The vinegar helps extract minerals from the bones.
  3. Simmer: Bring the water to a boil, then reduce the heat to a low simmer. Cover the pot and cook for 12-48 hours. Add any desired vegetables or herbs during the last 8 hours.
  4. Strain and Store: Strain the finished broth into glass jars, discarding the solids. You can store the broth in the refrigerator for up to a week or freeze it for longer periods.

Breaking Your 72-Hour Fast Safely

Reintroducing food correctly after an extended fast is as important as the fast itself to avoid digestive upset. The transition period should last at least as long as your fast.

The Re-feeding Process

  • Start with Broth: The first thing you consume should be a mug of bone broth to ease your digestive system back into action. This helps re-hydrate and provides easily absorbed nutrients.
  • Day 1 (Post-Fast): Stick to soft, easy-to-digest foods like blended vegetable soups, soft-cooked vegetables, and a small portion of lean protein like fish or eggs. Avoid raw, fibrous vegetables, heavy carbs, or spicy foods.
  • Day 2: You can begin to incorporate small amounts of healthy fats and more fibrous foods. Examples include avocados or fermented foods like kefir or unsweetened yogurt.
  • Day 3: Gradually resume your normal, healthy eating pattern. Avoid overeating and processed foods.

Potential Benefits and Risks

Benefits of a Bone Broth Fast

  • Gut Health: The gelatin and amino acids in bone broth are known to support gut integrity and decrease inflammation.
  • Weight Management: A significant reduction in calorie intake and the promotion of a ketogenic state can lead to weight loss.
  • Reduced Inflammation: The anti-inflammatory properties of bone broth can help manage conditions like joint pain and support immune function.
  • Cellular Repair: Like a water fast, a modified fast can still trigger autophagy, the body's natural process of cellular cleanup.

Risks and Considerations

  • Electrolyte Imbalance: Extended fasting, even with bone broth, can lead to mineral depletion. Monitoring for symptoms is key.
  • Fatigue and Dizziness: Initial side effects can include low energy, headaches, and lightheadedness as your body adapts to ketosis.
  • Social Isolation: Fasting can interfere with social events centered around food.
  • Not for Everyone: People with specific medical conditions, pregnant or breastfeeding women, and those with a history of eating disorders should not attempt this fast.
