Staying on versus going off a diet: effects on eating in normal weight and overweight individuals
1992
Lowe, M.R.
Past studies on the behavioral effects of dieting in overweight individuals have produced conflicting results. Overweight restrained eaters and self-initiated dieters have eaten little whether preloaded or not, whereas overweight individuals who have lost weight in weight reduction programs have eaten a lot whether preloaded or not. The present study examined the effects of requiring overweight self-initiated dieters to stay on or "go off" their diets for 2 days. A control group of normal weight self-initiated dieters was subjected to the same dieting manipulation. All subjects then participated in an ostensible ice cream taste test. Overweight subjects who stayed on their diets ate almost twice as much as overweight subjects who went off their diets; the intake of normal weight subjects was unaffected by the dieting manipulation. A cognitive explanation was developed to account for the findings of the present study along with those of past studies on self-initiated and weight-loss dieting.
