Restrained and unrestrained eaters were weighted 5 lb (2.27 kg) heavier or 5 lb lighter than their actual weight or were not weighed at all. Unrestrained eaters and restrained eaters who were told they weighed 5 lb less were not affected by the false weight feedback. However, restrained eaters who were informed that they weighted 5 lb more reported lower self-esteem, less positive moods, and more negative moods than did restrained eaters in the other 2 conditions. Furthermore, restrained eaters who were led to believe that they weighed heavier ate significantly more food during a subsequent "taste test" than did each of the other groups. Restrained eaters who believed that they were heavier experienced lowered self-worth and a worsening of mood that led them to relinquish their dietary restraint and overindulge in available food. Implications for patients with eating disorders are discussed.
受限制饮食者和不受限制饮食者的体重被设定为比其实际体重重5磅（2.27千克）或轻5磅，或者根本不称体重。被告知体重轻5磅的不受限制饮食者和受限制饮食者不受虚假体重反馈的影响。然而，被告知体重重5磅的受限制饮食者比其他两种情况下的受限制饮食者报告的自尊更低、积极情绪更少、消极情绪更多。此外，在随后的“味觉测试”中，认为自己体重更重的受限制饮食者比其他组中的每一组吃的食物都明显更多。认为自己体重更重的受限制饮食者经历了自我价值的降低和情绪的恶化，这导致他们放弃饮食限制并过度食用可得的食物。文中讨论了对饮食失调患者的启示。
