Step by step
The longer answer
Vitamin Water Zero is a gray-area fasting drink because it is low or zero calorie but sweetened. 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 vitamin water zero makes you hungrier, switch back to water, plain tea, or black coffee for a cleaner test.
Changing the rule for vitamin water zero every day and then not knowing what actually helped.
Track the fasting window, vitamin water zero, hunger, energy, and whether you finished the fast.
