Step by step
The longer answer
Stevia in coffee is a gray area: it may be zero calorie, but strict fasting usually avoids sweeteners. 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 stevia in coffee makes you hungrier, switch back to water, plain tea, or black coffee for a cleaner test.
Changing the rule for stevia in coffee every day and then not knowing what actually helped.
Track the fasting window, stevia in coffee, hunger, energy, and whether you finished the fast.
