In Undiet
Prolonged Fasting is an eating pattern in the Undiet catalog. Marking it records what you are already doing: a self-report marker, never a recommendation. From that day it is a period on your timeline, with your weight and how the days felt drawn across it, and what happens after you stop kept as a period of its own.
