In the 16:8 protocol you eat within an eight hour window and fast for sixteen. With a last meal at 8 pm the window reopens at noon the next day. Water, black coffee and unsweetened tea are allowed while fasting. The 14:10 and 18:6 schemes follow the same logic.
Eating window
12:00 - 20:00
Window reopening = last meal hour plus the protocol's fasting hours. The window covers the remaining hours of the day and should hold two or three complete meals.
