                                While the ProLon Fasting Mimicking Diet is designed to be followed exactly, ProLon's official guidelines permit a limited amount of black coffee per day to help manage potential caffeine withdrawal headaches. This exception is a key point for many who are used to a daily caffeine ritual. Understanding the specific rules is crucial to maximize the benefits of the 5-day program while minimizing discomfort.
