RESTRAINT THEORY

cause & consequences of cognitive restriction of food. attempting not to eat increases probability of overeating.
the boundary level states that dieters set themselves a diet boundary & try to eat within this self-imposed limit. but they sometimes break this boundary & binge until full because their satiety boundary overrides the self-imposed boundary, leading to overeating.
supporting study assigned obese women to restrained eating, exercise or no treatment group. Food intake & appetite were assessed in 2 lab conditions, & for both, women in the restraint group ate more than women in the other groups.

shows that overeating shown by many dieters is actually caused by their attempts to diet.

does not explain how the minority do succeed at weight loss through restrained eating. anorexics also experience huge weight loss without recourse to overeating.
challenging studies: pre-load/taste-test methodology used & found dieters do consume fewer calories after both low & high calorie pre-loads. tests like these are set in a lab and are highly unrealistic, lacking ecological validity as they cannot be generalised to real world settings. More naturalistic experiments used dietary self-monitoring forms & have also found dieters do eat less than non-restrained eaters & don't fall prey to overeating.
the conflict between findings of different studies may be due to different measures to assess dietary restraint. it may be that some measures do not incorporate overeating to the same extent as the Restraint Scale & this would explain why some research has not found dieters overeat.

individual differences contribute to success rates: low restrainers find dieting easy & high restrainers find it difficult as they may be hypersensitive to food cues & likely to abandon diets & one study found that they could not resist forbidden chocolate.
