Does sports drink break a fast?
Quick answer
Most sports drinks break a fast because they contain sugar and calories.
Step by step
01 Decide if your fast is strict, practical, medical, or religious.
02 Check whether sports drink contains calories, sugar, protein, fat, or sweeteners.
03 If unsure, keep the fasting window simple and move sports drink to your eating window.
The longer answer
Most sports drinks break a fast because they contain sugar and calories. They belong in the eating window unless a clinician told you otherwise. If your goal is a clean fasting window, treat sports drink 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 sports drink, then compare hunger and consistency over a few fasts.
Common mistake
Assuming sports drink is automatically fasting-safe without checking the label or your fasting goal.
Track in the app
