Can you have apple cider vinegar while intermittent fasting?
A tiny amount of apple cider vinegar in water is unlikely to matter for a practical fast, but avoid gummies or sweetened versions.
Step by step
The longer answer
A tiny amount of apple cider vinegar in water is unlikely to matter for a practical fast, but avoid gummies or sweetened versions. In everyday intermittent fasting, the easiest rule is to keep the fasting window to water, plain tea, and black coffee unless you intentionally follow a modified fast. Track the choice so you can see whether it affects cravings or consistency.
If apple cider vinegar makes you hungrier, switch back to water, plain tea, or black coffee for a cleaner test.
Changing the rule for apple cider vinegar every day and then not knowing what actually helped.
Track the fasting window, apple cider vinegar, hunger, energy, and whether you finished the fast.
