The relationship between night eating symptoms and disordered eating attitudes via insomnia and chronotype differences

In mammals, diurnal rhythms in behavioral and physiological are driven by a circadian clock which is managed by the suprachiasmatic nuclei (SCN) as the main pacemaker in the hypothalamus and by peripheral oscillators from most body cells. The SCN is mainly regulated by light/dark cycles, as the executive of the circadian clock, plays a leading role in determining chronotypes (Mendoza, 2007; Zerbini and Merrow, 2017). Numerous studies over the years have revealed that these “chronotypes” differ from each other in the timing of physiological variables, such as body temperature, cortisol and melatonin secretion; as well as in psychological variables, such as alertness, happiness, and task performance.
