The aim of this study was to examine the relationship between eating habits and lifestyle-related factors according to dieting experiences. University students (348 females) completed questionnaires regarding morningness-eveningness, stress responses, newly developed abnormal eating habits, lifestyle-related aspects, dieting methods, and body size. Factor analysis of abnormal eating habits produced three factors: simple and easy meals, irregular meal times, and frequent skipping of meals. Participants were then classified into four groups based on dieting dependency level, and multiple regression analyses were conducted with each sub-scale of abnormal eating habits as the dependent variable by group. The results were as follows. In those individuals who tended to stay up late at night, their states of eating habits were disturbed, regardless of their level of dieting. In contrast, both stress responses and lifestyle-related variables, such as commuting time and return time to home, had different effects on eating habits, depending on the level of dieting. Additionally, highly addictive dieters with abnormal eating habits were more likely to adhere to dieting.
