Fasting question
Can you have zero-sugar energy drink while intermittent fasting?
Short answer
A zero-sugar energy drink may not break a practical fast by calories, but caffeine and sweeteners can cause jitters or cravings.
Step by step
1
Look up the calories and ingredients for zero-sugar energy drink.
2
Choose a rule before the fast starts so you are not deciding while hungry.
3
Use the same rule for at least a few fasts before judging whether it works.
Example
If zero-sugar energy drink makes you hungrier, switch back to water, plain tea, or black coffee for a cleaner test.
