Dieting involves trying to eat less than usual. It involves placing a cognitive limit on food intake and attempting to eat up to a limit that is less than usual. Research has shown that up to 70% of women diet at some point in the lives, which shows that dieting happens often which can either be successful or unsuccessful. Studies by Herman and Mack (1975) and Wardle and Beales (1988) show success and failure of dieting and the causes and consequences. Also Failure to Dieting has been linked to overeating which will be discussed as they play a major role of Dieting. Other research which I will involve has shown to support these studies or shown how dieting can be unsuccessful and can result to overeating. Herman and Mack (1975) proposed a study using the Preload/ test method which is called the restrained theory. The participants were 45 female students. It was developed as an attempt to explain both the causes and consequences associated with the cognitive restriction to food intake. The study was an independent design with 15 participants in each three conditions. The first group received no preload and the second group were given one milkshake as a preload. The third group were given two milkshakes as preload. Groups 2 and 3 were asked to rate the taste qualities of the milkshakes. All participants were then given three tubs of ice cream of different flavours and given 10 minutes to rate the taste qualities, they were told they could eat as much ice cream as they wanted. All participants were given a questionnaire to assess their degree of dietary restraint. The results show that each group was divided into either dieters of non dieters sub groups. Herman and Mack (1975) found that non dieters ate less of the ice cream in the two milkshake preload condition than in the one or zero preload conditions. However dieters ate significally more ice cream in the one
