Intermittent fasting has become one of the most widely adopted wellness practices in Canada — and for good reason. The metabolic, cognitive, and gut health benefits are well-documented. But one question comes up consistently in the fasting community: does bone broth break a fast?
The honest answer is nuanced. And the broth you choose matters more than most fasting guides acknowledge.
Does Bone Broth Break a Fast?
Technically, bone broth contains calories — primarily from protein and fat — so it does interrupt a strict water fast. However, the fasting community broadly distinguishes between two goals:
Caloric fasting — zero calories, maximum autophagy. Bone broth is not appropriate here.
Metabolic fasting — the primary goal is fat burning, insulin management, and metabolic reset. Here, bone broth is not only acceptable but actively beneficial. Its protein content is low enough not to trigger a significant insulin response, while its electrolytes and minerals actively support the fasting state.
For the vast majority of people doing 16:8, 18:6, or extended 24-hour fasts for metabolic health, bone broth is one of the most valuable tools available.
Why Bone Broth and Fasting Work Together
Electrolyte Replacement
One of the most common reasons people struggle with fasting — headaches, fatigue, brain fog, muscle cramps — is electrolyte depletion. When you're not eating, you're not replenishing sodium, potassium, magnesium, and calcium through food.
HOTRO.ca's Nourish Yourself bone broth, made from roasted BC bones coated in tomato paste and diced tomatoes before simmering, is naturally rich in bio-available minerals extracted directly from the bone matrix. A single cup replaces electrolytes without sugar, artificial additives, or the insulin spike of a sports drink.
Gut Lining Support During the Fasting Window
Fasting gives your digestive system a rest — but the gut lining still needs support. The gelatin and glycine in bone broth coat and soothe the intestinal wall, reducing inflammation and supporting the gut barrier during the fasting period. This is particularly valuable for anyone doing extended fasts or fasting with a history of digestive sensitivity.
Hunger Suppression Without Breaking Metabolic State
The amino acids in bone broth — particularly glycine — have a documented appetite-suppressing effect. A cup of warm broth during a fasting window takes the edge off hunger without the blood sugar spike that would end the fast metabolically. It's the difference between white-knuckling a fast and moving through it comfortably.
Collagen and Muscle Preservation
Extended fasting carries a risk of muscle catabolism — the body breaking down muscle tissue for energy. The amino acid profile in bone broth, particularly glycine and proline, provides the building blocks for collagen synthesis and helps preserve lean muscle mass during the fasting window.
The Nourish Yourself Bone Broth Fasting Protocol
16:8 or 18:6 fasting:
- One cup of Nourish Yourself bone broth mid-fast (around hour 10–12) to manage electrolytes and hunger
- Break your fast with a protein-rich meal featuring BC grass-fed beef or organic chicken
24-hour or extended fasting:
- One cup morning, one cup early evening during the fasting window
- Choose Chicken Bone Broth — The Recovery Coach for a lighter option, or Beef Bone Broth — The Metabolic Booster for maximum mineral density
Keto + fasting combination:
- Bone broth is naturally keto-compatible — no carbohydrates, high in fat-soluble nutrients
- The Dashi Bone Broth — The Gut Whisperer adds prebiotic kombu for microbiome support during the fasting window
Why Flavour Matters When You're Fasting
When bone broth is your primary source of nourishment during a fasting window, flavour isn't a luxury — it's what makes the protocol sustainable.
Nourish Yourself Bone Broth achieved the highest aggregate ratings in independent blind tastings across major Canadian bone broth brands — the only award-winning broth in the comparison. Tasters consistently rate it as the most versatile and most flavourful in the category.
A broth you genuinely look forward to drinking is a fast you'll actually stick to.
