Early Time-Restricted Eating

eTRE reduces evening appetite and late-night grazing. An eTRE schedule of 9 AM first meal and 1 PM last meal within a 20-hour fast is one concrete implementation. Early time-restricted eating changes only the timing of the eating window, not its duration or diet composition. Meal timing is an independent variable from fasting duration and diet quality. eTRE creates social friction because eating nothing after 3 PM conflicts with shared evening meals. eTRE is particularly relevant when results have plateaued, sleep quality is poor, or evening hunger is a persistent problem.
