Attempted to replicate and expand the preliminary results of J. Polivy (1976), which showed a trend for low-restrained Ss to eat more when they thought they had eaten a low-calorie preload and high-restrained Ss to eat more when they thought they had consumed a high-calorie preload. The present study examined the amount of ice cream consumed by 20 underweight, 20 normal-weight, and 20 overweight college-age females after half had been told that they had previously drunk a very high-calorie drink and the other half had been instructed that the drink was very low calorie. The Ss were also divided by their score on an eating habits questionnaire into restrained (i.e., dieter) and unrestrained (i.e., nondieter) groups. Results show that those Ss who were restrained ate twice as much ice cream when they had been told that the preload drink was high calorie, as compared with the “told-low-calorie” condition. Research and therapeutic implications for weight-loss maintenance are discussed. (13 ref) (PsycINFO Database Record (c) 2006 APA, all rights reserved)
