Woah there! Let’s not get crazy. Yes. You can have a cup of coffee or some tea, but remember that you are fasting. Anything that promotes a metabolic response will break your fast. This includes keto coffee, bulletproof coffee, and large amounts of coffee. Try sticking to one cup for now and see how that goes. Some people can get away with slightly more – some, none at all. Oh! And remember, no fruity teas, as most of them have hidden juice and sugars.
