Yes, you can drink coffee while fasting, provided it is black coffee without any added ingredients like sugar, milk, or creamer. Black coffee has very few calories (around 3-5 per cup) and does not break a fast because it does not stimulate insulin or significantly affect blood glucose levels. Drinking black coffee during fasting may even enhance some benefits of fasting, such as fat burning, appetite suppression, and autophagy (cellular cleanup process). However, adding calories in the form of cream, sugar, or flavored syrups will break the fast. It's also recommended to drink coffee in moderation and stay hydrated with water during fasting.

Key Points about Coffee and Fasting

• Black coffee is fasting-friendly with minimal calories and no impact on insulin or glucose.

• Additives like milk, sugar, and cream break the fast by adding calories.

• Coffee can help suppress appetite and improve mental alertness during fasting.

• Drinking coffee may enhance autophagy and fat burning.

• Limit caffeine intake to avoid side effects such as anxiety or sleep disruption.

In summary, plain black coffee can be safely consumed during fasting without breaking the fast or compromising its benefits, but avoid any additions that add calories.
