Does bone broth break a fast?

Last reviewed · Jun 29, 2026 · Not medical advice
Quick answer

Bone broth breaks a strict fast because it contains calories and protein.

Step by step

01 Decide if your fast is strict, practical, medical, or religious.
02 Check whether bone broth contains calories, sugar, protein, fat, or sweeteners.
03 If unsure, keep the fasting window simple and move bone broth to your eating window.

The longer answer

Bone broth breaks a strict fast because it contains calories and protein. Some fasting styles allow broth, but it is not a zero-calorie fast. If your goal is a clean fasting window, treat bone broth as something for the eating window. If you are doing a modified fast, define your rule clearly and track it consistently.

Tip

Use Fast Goblin notes to mark gray-area choices like bone broth, then compare hunger and consistency over a few fasts.

Common mistake

Assuming bone broth is automatically fasting-safe without checking the label or your fasting goal.
