FASTING
Bone Broth Fast: The Gentler Deep Clean
Not ready for pure water fasting? A bone broth fast offers gut healing, reduced inflammation, and metabolic benefits — with built-in nourishment.
Bone broth fasting means consuming only bone broth (and water) for a set period — typically 1-5 days. It's a modified fast that maintains some of the benefits while providing minerals, collagen, and amino acids.
It's often called the "gateway fast" — easier to do, gentler on the body, and a great introduction to extended fasting.
Who Should Consider a Bone Broth Fast
Fasting beginners
If pure water fasting feels too extreme, bone broth fasting is a gentler entry point.
Gut issues
The collagen, gelatin, and amino acids in bone broth specifically support gut lining repair.
Those with adrenal or stress issues
Pure fasting can stress already-stressed systems. Bone broth fasting is less demanding.
People who need to keep working
Bone broth provides some calories and nutrients. Energy crashes are less severe than water fasting.
Transition into or out of water fasting
Excellent as a lead-in to extended fasting or as a gentle refeed protocol.
Benefits of Bone Broth Fasting
Gut healing
Collagen and gelatin help repair the gut lining. L-glutamine — abundant in bone broth — is the primary fuel for intestinal cells.
Reduced inflammation
The glycine in bone broth has anti-inflammatory effects. Many people report joint pain relief.
Electrolytes included
Good bone broth is naturally rich in sodium, potassium, and magnesium. Less supplementation needed.
Easier adherence
Having something warm and savory to consume makes the fast more sustainable, especially in cold weather.
Some metabolic benefits
While not as powerful as pure fasting, you still get lowered insulin, increased fat burning, and digestive rest.
What You Give Up vs. Water Fasting
Bone broth contains protein and calories. This means:
Autophagy is reduced
Amino acids (especially leucine) activate mTOR, which inhibits autophagy. You get some autophagy, but not the deep cellular cleanup of pure fasting.
Ketosis is lighter
The protein and small amount of calories slow ketone production. You'll be in mild ketosis, not deep ketosis.
Stem cell activation is less
The immune reset and stem cell activation seen at 72+ hours of water fasting doesn't happen the same way.
The tradeoff: You get gut healing, reduced inflammation, and easier fasting — but sacrifice some of the deeper metabolic benefits.
The Bone Broth Fasting Protocol
Daily protocol:
- Amount: 3-6 cups (24-48 oz) of bone broth per day
- Timing: Space throughout the day. Morning, midday, evening.
- In between: Water, herbal tea, black coffee
- Duration: 1-5 days (3 days is common)
Drink the broth warm. Sip slowly. If hunger is intense, have another cup of broth rather than breaking the fast.
What to Expect
Day 1
Hunger comes and goes, especially at your normal meal times. The warm broth helps. Energy is usually stable.
Day 2
Often easier than Day 1. You're adapted. Some people notice clearer thinking, reduced bloating.
Day 3
Deep gut rest. Many people report feeling "clean." Joint pain often improved. Digestion feels different.
Day 4-5 (if extended)
Continued benefits. Some weight loss (mostly water, some fat). Strong reset feeling.
What Makes Good Bone Broth
Not all broth is created equal. You want the real thing:
Long-cooked
Minimum 12 hours for chicken, 24+ hours for beef. This extracts collagen, minerals, and amino acids.
Gelatinous when cold
Good bone broth becomes jiggly in the fridge. That's the gelatin — the good stuff.
Quality bones
Ideally grass-fed beef or pasture-raised chicken. Joints, knuckles, feet — these have the most collagen.
No additives
Many store-bought "bone broths" are just stock with added flavoring. Read ingredients. Or make your own.
Simple Bone Broth Recipe
Ingredients:
- • 2-3 lbs bones (beef marrow bones, chicken carcass, or both)
- • 2 tbsp apple cider vinegar
- • Water to cover
- • Salt to taste
- • Optional: onion, garlic, celery, herbs
Method:
- 1. Place bones in large pot or slow cooker
- 2. Cover with water, add vinegar (helps extract minerals)
- 3. Bring to boil, then reduce to low simmer
- 4. Chicken: 12-24 hours. Beef: 24-48 hours.
- 5. Strain, salt to taste, store in fridge or freeze
Store-Bought Options
If you don't want to make your own, look for:
- • Kettle & Fire — widely available, good quality
- • Bonafide Provisions — frozen, very high quality
- • Epic Provisions — shelf-stable, decent
- • Local butcher shops — often make real broth
Check the label:Should gel when cold. Avoid anything with "natural flavors" or ingredients you don't recognize.
Breaking a Bone Broth Fast
Because you've been consuming protein and minerals, breaking a bone broth fast is easier than breaking a water fast. Still, be gradual:
First meal
Start small. Soft-cooked eggs, avocado, soft vegetables. Your stomach has been resting.
Second meal (3-4 hours later)
Normal meal, moderate portion. You can eat more variety now.
Day 2
Normal eating. Pay attention to how foods affect you — sensitivities are often clearer.
Variations
Bone Broth + Fat
Adding butter or coconut oil to broth keeps you in ketosis while providing more satiety. Some call this "fat fasting."
Bone Broth + Collagen
Adding collagen powder to broth increases gut-healing benefits. More protein, so further from pure fasting.
Bone Broth as Transition
One day of bone broth before water fasting eases the transition. Also excellent for breaking a water fast.
Who Should Be Cautious
- • Histamine intolerance: Bone broth is high in histamine. If you react to fermented foods or aged foods, be careful.
- • Oxalate issues: Bone broth is generally low oxalate, but quality varies.
- • Kidney problems: High protein intake may be an issue — consult a doctor.
- • Pregnancy/breastfeeding: Modified fasting may be fine, but get medical advice first.
