Stability of the timing of food intake at daily and monthly timescales in young adults

A. W. Mchill, C. J. Hilditch, et al.

This fascinating study by Andrew W. McHill and colleagues reveals that while daily eating patterns fluctuate wildly—showing a striking three-hour variation—average eating timing remains surprisingly stable over the course of months. This research highlights the dual importance of daily and monthly timescales in understanding our eating habits.

Abstract

This study examined the stability of eating timing in young adults across one semester, using both clock hour and relative circadian time. Day-to-day clock timing of caloric events showed poor stability (~3-h variation), while the timing of eating was more stable across months (~1-h variation). However, stability was less consistent when measured relative to circadian timing. The findings suggest that while daily eating patterns are variable, weekly average eating timing is stable across months, indicating the importance of considering both daily and monthly timescales when assessing eating habits.
