ObjectivesExamine the association between components of restrained eating, cognitive performance and weight loss maintenance.Methods106 women, all members of a commercial slimming organisation for at least 6 months (mean ± SD: 15.7 ± 12.4 months), were studied who, having lost 10.1 ± 9.7 kg of their initial weight, were hoping to sustain their weight loss during the 6 month study. Dietary restraint subcomponents flexible and rigid restraint, as well as preoccupying cognitions with food, body-shape and diet were assessed using questionnaires. Attentional bias to food and shape-related stimuli was measured using a modified Stroop test. Working memory performance was assessed using the N-back test. These factors, and participant weight, were measured twice at 6 month intervals.ResultsRigid restraint was associated with attentional bias to food and shape-related stimuli (r = 0.43, p < 0.001 resp. r = 0.49, p < 0.001) whereas flexible restraint correlated with impaired working memory (r = − 0.25, p < 0.05). In a multiple regression analyses, flexible restraint was associated with more weight lost and better weight loss maintenance, while rigid restraint was associated with less weight loss.ConclusionsRigid restraint correlates with a range of preoccupying cognitions and attentional bias to food and shape-related stimuli. Flexible restraint, despite the impaired working memory performance, predicts better long-term weight loss. Explicitly encouraging flexible restraint may be important in preventing and treating obesity.
► Flexible restrained eating behaviour is associated with better weight loss.
► Flexible restraint is associated with better weight maintenance.
► Rigid restraint is associated with attentional bias to food and shape.
► Prevention and treatment of obesity should enhance flexible restraint.
