1. The “White-Knuckle” Phase of Fasting

Intermittent fasting (like 16:8 or 5:2) is popular in the UK because many people find it simpler than calorie counting. Still, there is a common hurdle: the late-morning wall. That moment when your stomach growls, focus drops, and the fast starts to feel like a punishment.

This is where a warm, savoury option like bone broth can be useful. It does not “hack biology” or replace good habits, but it can take the edge off hunger and help you stay consistent—especially on busy workdays.

2. The Honest Verdict: Does Bone Broth “Break” a Fast?

It depends on why you are fasting—and how strict you want to be.

  • For routine appetite control and consistency: Many people include bone broth during a fasting window because it is low in carbohydrates and sugars compared with most snacks. However, it still contains calories and amino acids, so it is not a “true” zero-intake fast.
  • For stricter fasting goals: If you are fasting specifically to keep intake at absolute zero, then any broth counts as breaking the fast.
  • For autophagy-focused fasting: Research is still evolving, but amino acids may reduce some fasting signals. If your goal is “as strict as possible,” water (and possibly black coffee/tea) is the simplest approach.

The practical takeaway: choose the version of fasting you can actually stick to. Consistency beats perfection.

3. The “Keto Flu”, Headaches, and Electrolytes

When people feel rough while fasting, it is often not just hunger. Hydration and electrolytes (especially sodium) can matter—particularly if you also reduce carbohydrates.

Bone broth can be a comforting warm drink during this phase. Still, it is best to be realistic: Collanature’s nutrition panel shows the Natural (No-Flavour) portion is very low in salt, so it should not be treated as a full electrolyte solution on its own. If you are prone to dizziness or headaches while fasting, consider adding a pinch of salt to warm broth (if it suits you) or using an electrolyte product.

4. What About Muscle While You’re Fasting?

A common worry is muscle loss. In real life, what matters most is your total protein intake over the day (and week), plus resistance training and adequate calories in your eating window.

A small serving of bone broth can help with satiety and may make fasting easier to maintain. But it is not a magic shield against muscle loss—think of it as a supportive tool, not a replacement for a protein-forward diet and strength training.

5. Frequently Asked Questions

1. How many calories are in a serving?

According to Collanature’s product nutrition information for the Natural (No-Flavour) option, a portion of about 50g provides approximately 15 kcal and around 4.75g protein. This is low, but it is not “zero,” so it depends how strictly you define your fast.

2. Can bone broth spike insulin?

Any protein can trigger some insulin response in some people. Bone broth is typically low in carbohydrates, which may make its blood-sugar impact smaller than most snack foods, but it is not accurate to claim “no insulin response” for everyone.

3. Can I add butter or MCT oil?

You can, but be honest about the trade-off: adding fats increases calories and changes the purpose from “fasting support” to “a small meal.” Some people do this in keto-style routines; others avoid it if fat triggers reflux or slows digestion.

4. Will bone broth stop weight loss?

Used strategically, it can help some people avoid the rebound binge that happens when they end a fast overly hungry. Weight change still comes down to your overall intake, food quality, sleep, and consistency across weeks—not a single mug of broth.

5. Which Collanature option is best during fasting?

Most people start with the Natural (No-Flavour) option because it is neutral and easy to fit into different routines. If you prefer a fruitier taste profile, you can also choose the berry option—just use the product page nutrition info as your source of truth for macros and ingredients.

Final Thoughts

Fasting should feel like a sustainable routine, not a daily battle. If a warm cup of bone broth helps you stay consistent, it can be a smart, low-drama tool—just don’t oversell it as “not breaking the fast.” Define your goal, pick the level of strictness you can maintain, and keep the fundamentals strong.
