Dr. Jason Fung, a prominent nephrologist and fasting expert, advocates for various fasting protocols, ranging from shorter daily fasts to extended periods. The optimal length of a fast depends heavily on an individual's health goals, experience level, and a crucial emphasis on medical supervision, especially for longer durations.

According to the principles of Dr. Jason Fung, a leading expert on intermittent fasting, black coffee is considered a safe beverage during a fasting window and will not break a fast. This is because it contains minimal calories and does not cause a significant insulin spike, which is the primary factor that halts the fasted state.
