The goal of this study was to evaluate the effect of physical activity and self-reported eating style on weight change up to 48 months after primary RYGB. The results sug- gest that patients’ activity and eating style before RYGB are not related to weight loss or weight regain after surgery. In general patients became more active after surgery and had less emotional, external and restrained eating. Physical activity at 15, 36 and 48 months follow-up was positively associated with weight loss; patients who became more active after surgery had higher weight loss. Emotional eating was re- lated to weight loss at all follow-up moments; patients with more emotional eating compared to baseline had less weight loss. The reporting of higher emotional eating at 48 months follow-up was also related to higher weight regain at 48 months. Exter- nal eating only related to weight loss at 24 months follow-up; patients who reported more external eating at follow-up had less weight loss. Restrained eating was also negatively associated with weight loss up to 36 months follow-up; patients who re- ported more restrained eating at follow-up had less weight loss. Patients who experi- enced more restrained eating at 36 months follow-up also had higher weight regain at this FU moment. Since the mixed model compared scores on the questionnaire with baselines scoring, the model in fact shows that the post-surgery change in physical activity and self-reported eating style was related to weight loss.
