Intermittent fasting is a popular diet pattern that involves cycling between periods of eating and fasting.
Research suggests that intermittent fasting may promote weight loss and reduce risk factors for certain chronic conditions, such as heart disease, diabetes, and Alzheimer’s disease.
If you’re new to intermittent fasting, you may wonder whether you’re allowed to drink coffee during a fast.
Drinking moderate amounts of very low- or zero-calorie beverages during a fasting window is unlikely to compromise your fast in any significant way.
This includes drinks like black coffee.
One cup (240 ml) of black coffee contains about 3 calories and very small amounts of protein, fat, and trace minerals.
For most people, the nutrients in 1–2 cups (240–470 ml) of black coffee aren’t enough to initiate a significant metabolic change that would break a fast.
Some people say that coffee suppresses your appetite, making it easier to stick with your fast in the long term. .
Overall, drinking coffee moderately won’t significantly disrupt your intermittent fast. Just be sure to keep it black, without any added ingredients.
