What Is Bone Broth Fasting?

Bone broth fasting involves replacing all solid food with nutrient-rich bone broth and non-caloric liquids for a defined period, typically 24 to 72 hours. You consume 5-8 cups (2-3 quarts) of bone broth throughout each fasting day, supplemented with water and herbal teas.

This method differs fundamentally from other fasting approaches. Water fasting provides zero nutrients, often causing fatigue and electrolyte imbalances. Juice fasting delivers sugar spikes that can disrupt the metabolic benefits of fasting. Bone broth fasting maintains the fasted state while supplying collagen, amino acids like glycine, and essential minerals that support cellular repair and digestive healing.

For a deeper dive into the nuances of this approach, you may want to explore the bone broth fast guide, which covers practical tips and real-world experiences.

A typical 48-hour bone broth fast involves sipping one cup every 2-3 hours, starting upon waking and ending two hours before bed. The consistent nutrient flow prevents the dramatic energy crashes common with other fasting methods while still triggering autophagy and metabolic benefits.

How Bone Broth Fasting Works: The Science

During bone broth fasting, your body shifts from glucose-burning to fat-burning mode within 12-16 hours. Glycogen stores deplete, insulin levels drop, and mild ketosis begins, the metabolic state where your body efficiently burns stored fat for fuel. Unlike complete food restriction, bone broth provides just enough nutrients to support this transition without breaking the fast.

Autophagy, your body's cellular cleanup process, increases significantly after 16-24 hours of fasting. This mechanism removes damaged proteins and organelles, essentially giving your cells a thorough spring cleaning. The amino acids in bone broth, particularly glycine, actually support this process while protecting gut lining integrity.

The "gut reset" occurs as your digestive system gets a break from processing complex foods while receiving targeted nutrients. Glycine helps repair intestinal lining, collagen supports tissue regeneration, and minerals maintain electrolyte balance. Quality bone broths like Gourmend's include nori seaweed and oyster mushrooms, adding umami depth plus additional minerals that support cellular function during the fasting window.

Research indicates that growth hormone levels can increase up to 5-fold during fasting periods, supporting muscle preservation and metabolic efficiency. The consistent protein intake from bone broth helps maintain this benefit while preventing the muscle breakdown that can occur during extended water fasting.

Core Health Benefits of Bone Broth Fasting

Digestive benefits top the list for most practitioners. The extended break from solid food allows inflamed gut lining to heal while glycine and collagen provide building blocks for tissue repair. Many report significantly less bloating, improved regularity, and reduced digestive discomfort following a 3-day bone broth fast.

Skin, joint, and immune support stem from bone broth's collagen content, typically 8-12 grams per cup. The collagen peptides support skin elasticity and joint mobility, while amino acids like glycine and proline contribute to immune function. Gourmend bone broths enhance these benefits with nori seaweed and oyster mushrooms, delivering additional minerals and umami compounds that support overall wellness.

Energy, focus, and mental clarity often improve during bone broth fasting as the body shifts into mild ketosis. Many Gourmend customers report sharper concentration and sustained energy levels during 72-hour fasts, attributing this to the steady supply of electrolytes and amino acids. Unlike water fasting, which can cause fatigue and brain fog, bone broth provides enough nutrients to maintain cognitive function while still triggering autophagy.

Metabolic and weight management benefits include enhanced fat burning and improved insulin sensitivity. Research shows that fasting for 24-72 hours can increase human growth hormone levels by up to 300%, supporting muscle preservation and metabolic health. The protein content in bone broth, typically 8-10 grams per cup, helps maintain lean muscle mass during the fasting period.

Who Should (and Shouldn't) Try Bone Broth Fasting?

Ideal candidates include people with sensitive digestion seeking a gentle reset, those following low FODMAP protocols, and anyone looking to break unhealthy eating patterns. Our customer "IBS Irene" uses quarterly 48-hour bone broth fasts to manage digestive flare-ups, while "Gut Health Grace" appreciates the research-backed approach to cellular renewal. Clean-label enthusiasts like "Claire" choose bone broth fasting after travel to reset their system with transparent, organic nutrition.

People who should avoid bone broth fasting include pregnant or nursing women, individuals with eating disorders, those with diabetes (without medical supervision), underweight individuals, or anyone under active medical treatment. "Gluten Sensitive Gloria" always consults her doctor before starting any fasting protocol, especially given her autoimmune considerations.

Step-By-Step: How to Do a Bone Broth Fast

Preparation phase begins 2-3 days before your fast. Focus on gentle, low FODMAP meals featuring quinoa, rice, and easily digestible proteins. Increase water intake to 8-10 glasses daily and avoid processed foods. This preparation helps your digestive system transition smoothly into the fasting state.

During the fast, consume 5-8 cups of bone broth daily, spacing servings every 2-3 hours. Start with 1 cup upon waking, then continue with regular intervals throughout the day. Between bone broth servings, drink water, herbal teas, or black coffee in moderation. You may add chive sprigs or a pinch of sea salt for variety while maintaining the fast's integrity.

Comfort strategies include light movement like gentle yoga or short walks, warm baths with Epsom salts, and engaging in low-stress activities like reading or journaling. Avoid intense exercise during your fast, but don't remain completely sedentary.

Choosing the Best Bone Broth for Your Fast

Homemade bone broth offers complete control over ingredients. Simmer grass-fed bones with chive sprigs and green leek tops for 12-24 hours, avoiding high FODMAP ingredients like garlic bulbs or onion. A simple three-ingredient approach, bones, chives, and sea salt, creates a clean, digestible base perfect for fasting.
