The bone broth fasting program is a dietary approach that integrates the nutrient-rich qualities of bone broth with the practice of intermittent or periodic fasting. Rather than an absolute restriction of calories like a traditional water fast, this method allows for the consumption of nutrient-dense liquids, providing a gentler and more sustainable alternative for many individuals. Programs range from short-term cleanses lasting one to three days to more structured, long-term plans like the 21-day Bone Broth Diet.
The fundamental concept
At its core, a bone broth fast aims to give the digestive system a break from processing solid foods while nourishing the body with essential elements. The program can vary significantly, but it typically involves replacing meals with several cups of bone broth on specific days. This provides satiety and energy from protein and electrolytes, helping to manage hunger pangs and fatigue often associated with stricter fasts. Proponents claim this can help reset the gut, reduce inflammation, and kickstart weight loss.
How bone broth supports fasting
Bone broth is a savory liquid made by simmering animal bones, connective tissues, and often vegetables for an extended period, typically 12-24 hours. This process extracts a wealth of beneficial compounds, including:
- Collagen and gelatin: These proteins contribute to a feeling of fullness and support the health of the gut lining, skin, and joints.
- Amino acids: Glycine and glutamine are particularly abundant. Glycine aids in sleep and liver detoxification, while glutamine is a key fuel source for cells in the gut.
- Electrolytes and minerals: Bone broth is a natural source of minerals like sodium, potassium, and magnesium, which helps maintain hydration and prevent the fatigue commonly experienced during fasting.
Common bone broth fasting protocols
Numerous approaches exist, catering to different goals and experience levels:
- The 21-Day Bone Broth Diet: Popularized by Dr. Kellyann Petrucci, this plan involves eating a clean, Paleo-style diet for five days a week and conducting two non-consecutive mini-fasts using only bone broth.
- Short-term cleanses: A 1- to 3-day bone broth-only fast or cleanse is a popular option for a quick reset. During this time, participants consume only bone broth, water, and herbal tea.
- Intermittent fasting (16:8): For those practicing time-restricted eating, incorporating bone broth into the fasting window can help sustain energy levels and curb hunger.
Comparison of fasting methods
| Feature | Bone Broth Fasting | Water Fasting | Juice Cleansing |
|---|---|---|---|
| Calorie Intake | Very low (30-60 calories per cup) | Zero calories | Low to moderate (sugars from fruit/veg) |
| Nutrient Density | High (protein, minerals, electrolytes) | Very low (hydration only) | Variable (vitamins, but lacks protein/fiber) |
| Satiety | High (protein and gelatin help reduce hunger) | Very low (hunger is common) | Low (sugar can lead to spikes and crashes) |
| Impact on Insulin | Minimal (low-carb, low-sugar) | Minimal (zero calories) | High (can cause insulin spikes) |
| Digestive Rest | Provides significant rest to the digestive system | Provides total rest to the digestive system | Requires some digestion of plant sugars |
Who should and shouldn't fast with bone broth?
While bone broth fasting can be beneficial, it is not suitable for everyone.
Consider a bone broth fast if:
- You want to ease into fasting or need a gentler option than water fasting.
- You are looking to support gut healing and reduce inflammation.
- You want to jump-start weight loss or reset your diet.
Avoid bone broth fasting if:
- You are pregnant, nursing, or underweight.
- You have a history of disordered eating.
- You have certain medical conditions like diabetes, kidney disease, or high blood pressure, without a doctor's supervision.
Making your own bone broth
While high-quality pre-made bone broths are available, making your own can ensure control over ingredients and sodium levels. A simple recipe involves simmering bones (organic and grass-fed are best), a splash of apple cider vinegar, and optional vegetables and herbs for 12-24 hours. The apple cider vinegar helps pull minerals from the bones. The resulting broth can be strained and frozen in daily portions for convenience.
How to break your fast
Transitioning back to solid food slowly is crucial to avoid digestive upset. After a prolonged fast, the gut may be sensitive, so it's best to start with small, easily digestible meals.
- First meal: A small serving of fermented foods like yogurt or kefir, or a simple vegetable soup.
- Gradual reintroduction: Slowly reincorporate solid, whole foods like cooked vegetables, healthy fats, and small portions of protein over the next day or two.
- Avoid: Immediately consuming large meals, sugary foods, or processed items, which can cause discomfort and reverse the benefits.
Conclusion
For those seeking a less intense version of fasting, the bone broth fasting program offers a compelling blend of calorie restriction and nutrient support. By leveraging the protein, collagen, and electrolytes in bone broth, it helps manage hunger and supports various health goals, from gut healing to weight management. However, it is a restrictive diet that carries risks, particularly for those with pre-existing health conditions or a history of disordered eating. As with any significant dietary change, it is advisable to consult a healthcare professional, especially for longer fasts, to ensure it aligns with your individual health needs and goals. This program can be a valuable tool for a dietary reset when implemented safely and thoughtfully.
