Effects of false weight feedback on mood, self-evaluation, and food intake in restrained and unrestrained eaters.

Restrained and unrestrained eaters were weighed 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 weighed S 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. lmplications for patients with eating disorders are discussed.
