Abstract

Fifty-one observational studies revealed a 0.39 correlation between later chronotype and binge-eating scores.

  • Later chronotype is associated with higher scores in binge-eating, night-eating, food addiction, emotional eating, uncontrolled eating, and food craving.
  • The correlation for binge-eating is notably strong at 0.39, indicating a significant relationship.
  • A smaller positive correlation of 0.21 exists between later chronotype and night-eating.
  • Lower restrained eating is associated with later chronotype, with a correlation of -0.11.
  • The findings suggest a spectrum of disordered eating indicators linked to chronotype in the general population.
  • More longitudinal and randomized controlled trials are necessary to clarify causality and the mechanisms involved.
