Can you have cucumber water while intermittent fasting?
Cucumber-infused water is usually fine for a practical fast if you do not eat the cucumber.
Step by step
The longer answer
Cucumber-infused water is usually fine for a practical fast if you do not eat the cucumber. 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 cucumber water makes you hungrier, switch back to water, plain tea, or black coffee for a cleaner test.
Changing the rule for cucumber water every day and then not knowing what actually helped.
Track the fasting window, cucumber water, hunger, energy, and whether you finished the fast.
