Does MCT oil break a fast?
Quick answer
MCT oil breaks a strict fast because it is pure fat and calories.
Step by step
01 Decide if your fast is strict, practical, medical, or religious.
02 Check whether MCT oil contains calories, sugar, protein, fat, or sweeteners.
03 If unsure, keep the fasting window simple and move MCT oil to your eating window.
The longer answer
MCT oil breaks a strict fast because it is pure fat and calories. It may not spike glucose much, but it still supplies energy. If your goal is a clean fasting window, treat MCT oil 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 MCT oil, then compare hunger and consistency over a few fasts.
Common mistake
Assuming MCT oil is automatically fasting-safe without checking the label or your fasting goal.
Track in the app
Track whether you had MCT oil, the time, hunger level, and whether it made the fast easier or harder.
