title: Compensatory beliefs, nutrition knowledge and eating styles of users and non-users of meal replacement products.
abstract: Meal replacement products (MRPs) are used to regulate body weight, but the underlying eating behavior-related characteristics of MRP consumers are unknown. The study was based on an online survey of 490 women (221 who consume MRPs and 269 who do not) in Switzerland. Nutrition knowledge of calories, balanced meal composition and eating styles (restrained, emotional, external eating, overeating tendencies) were measured. In addition, compensatory beliefs regarding the effects of MRPs were assessed. The results showed that consumers of MRPs believed more strongly that MRPs can compensate for overeating, and that health behaviors key to successful weight regulation, such as physical exercise, do not have to be implemented when MRPs are consumed. Using binary logistic regression modeling, age, weight goal, compensatory beliefs regarding overconsumption, nutrition knowledge related to balanced meal composition, restrained eating and overeating tendencies were significant predictors of MRP consumption during the previous year. It was found that MRPs might be used as a license to indulge in palatable food, based on the perception that they can compensate for calorie overconsumption. Furthermore, they might help people with restraint eating tendencies and those who regularly overeat to compensate for overeating episodes and maintain dietary goals, even after excess food intake. Whether this approach is successful remains to be explored in future studies.
