                                While many fasting protocols permit black coffee and other non-caloric beverages, the impact of adding a sweetener can vary depending on your specific health goals and the type of sweetener used. The answer is not as simple as avoiding all calories, as certain low- and zero-calorie sweeteners may still trigger a metabolic response that can affect the benefits of your fast.
