Does butter coffee break a fast?
Quick answer
Butter coffee breaks a strict fast because butter adds calories and fat.
Step by step
01 Decide if your fast is strict, practical, medical, or religious.
02 Check whether butter coffee contains calories, sugar, protein, fat, or sweeteners.
03 If unsure, keep the fasting window simple and move butter coffee to your eating window.
The longer answer
Butter coffee breaks a strict fast because butter adds calories and fat. A fasting timer should count this as an eating-window choice. If your goal is a clean fasting window, treat butter coffee as something for the eating window. If you are doing a modified fast, define your rule clearly and track it consistently.
