A meta-analysis of the relationship between eating restraint, impaired cognitive control and cognitive bias to food in non-clinical samples.

Clin Psychol Rev 2021 Sep 8;89:102082. Epub 2021 Sep 8.

School of Psychology, UNSW Sydney, Australia.

Aim: Food restriction is argued to be a precursor for unhealthy preoccupation with food, possibly leading to the development of an eating disorder. We updated previous meta-analyses that examined the relationship between eating restraint and deficits in either general or food-related attentional and inhibitory control. We hypothesized that inconsistencies in the literature around eating restraint, impaired cognitive control, impulsivity and cognitive biases for food could be attributed to the scale used to measure eating restraint.
