16-Hour Fasting

A 16-hour fast is presented as a normal physiological state rather than starvation. The protocol sets a practical schedule of a noon first meal and an 8 PM latest final meal. The article treats 16 hours as a threshold where metabolic switching and autophagy become more consistent. A 16-hour overnight fast creates metabolic changes that are less likely when food is eaten every few hours. The suggested fasting pattern extends the interval between the last meal at night and the first meal the next day.
