What is the Origin of Meal Termination Time?

This concept is fundamental to the practice and research of time-restricted eating (TRE) and chrononutrition, where the temporal boundaries of the feeding window are paramount. The term emphasizes the importance of the final meal's timing in signaling the end of the digestive and storage phase to the body's metabolic organs. It is a practical, actionable parameter derived from chronobiological principles.

What is the Mechanism of Meal Termination Time?

The timing of the last meal is directly sensed by the peripheral circadian oscillators in the liver, pancreas, and gut, primarily through nutrient-sensing pathways like the insulin and mTOR signaling cascades. Setting an earlier meal termination time ensures that the feeding window does not overlap with the body's natural nocturnal decline in glucose tolerance and digestive capacity. This temporal constraint promotes a longer fasting phase, which activates endogenous repair mechanisms, such as autophagy, and facilitates the fat mobilization window.

Meal Termination Time

Meaning

Meal termination time is the precise clock time at which an individual concludes their final caloric intake for the day, serving as a critical zeitgeber for the body’s peripheral metabolic clocks. This time point establishes the beginning of the overnight fasting period, significantly influencing the duration of the body’s non-feeding state and the subsequent activation of metabolic repair pathways. Clinical protocols often utilize this time to optimize circadian rhythm alignment and metabolic health.
