Abstract
En 中文
A person's chronotype reflects individual variability in diurnal rhythms for preferred timing ofsleep and daily activities such as exercise and food intake. The aim of this review is to provide anoverview of the evidence around the influence of chronotype on eating behaviour and appetitecontrol, as well as our perspectives and suggestions for future research. Increasing evidencedemonstrates that late chronotype is associated with adverse health outcomes. A latechronotype may exacerbate the influence of greater evening energy intake on overweight/obesity risk and curtail weight management efforts. Furthermore, late chronotypes tend to haveworse diet quality, with greater intake of fast foods, caffeine and alcohol and lower intake offruits and vegetables. Late chronotype is also associated with eating behaviour traits thatincrease the susceptibility to overconsumption such as disinhibition, food cravings and bingeeating. Whether an individual's chronotype influences appetite in response to food intake andexercise is an area of recent interest that has largely been overlooked. Preliminary evidencesuggests additive rather than interactive effects of chronotype and meal timing on appetite andfood reward, but that hunger may decrease to a greater extent in response to morning exercise inearly chronotypes and in response to evening exercise in late chronotypes. More studiesexamining the interplay between an individual's chronotype, food intake/exercise timing andsleep are required as this could be of importance to inform personalised dietary and exerciseprescriptions to promote better appetite control and weight management outcomes.
