This study investigated dietary restraint as a predictor of subsequent
reported weight loss. Neither chronic dieters nor nondieters reported
actually losing weight over a 7-mo. period. With respect to recent we
ight change, restrained eaters reported both more recent weight loss a
nd more recent weight gain than unrestrained eaters. Further, such wei
ght changes had a much larger influence on their affect. It was conclu
ded that chronic dieting is likely to produce temporary swings in both
weight and mood but no permanent change. As such, chronic dieters mig
ht best be advised to abandon their dieting attempts.
