- Background: Sustainable dietary, behavioural and lifestyle changes are necessary to accomplish weight loss. Aim: Evaluate impact of internal motivation, locus of control and self-efficacy on non-surgical weight loss treatment in patients with severe obesity. Methods: A total of 1196 patients, Body Mass Index ≥35 kg/m2, referred to obesity treatment were included. Visual analogue scales for motivation, locus of control and self-efficacy were completed before starting weight loss treatment. Results: A total of 601 patients (42% drop out) completed 12-month weight loss treatment. After 12 months, 94.6% in the Very Low Energy Diet (VLED) group and 79.4% in the dietary treatment group had a weight loss of ≥5% of their body weight. No statistically significant associations were found between achieved weight loss in the VLED group, and locus of control or self-efficacy. Achieving ≥15% weight loss by dietary treatment was related to a higher score on self-efficacy compared to those who lost <5% in weight or dropped out. Conclusion: Self-efficacy appears to be important for weight loss when on dietary treatment without VLED. Attrition rate was higher among patients with lower score on self-efficacy at baseline. The study indicates that psychological factors associated with adherence to, and completion of weight loss treatment deserve attention.

- Background: The characteristics and prognosis of healthy obesity (HO) still remain unclear. We aimed to examine the characteristics of healthy severe obesity (HSO), defined by a novel approach, with a focus on self-reported physical activity (PA) and a genetic risk score for type 2 diabetes (GRS DM2). Methods: A cross-sectional analysis was carried out in a subsample of severly obese subjects (BMI≥35 kg/m2; n = 809) selected from the population-based Malmo Preventive Project (MPP). Subjects with HSO (n = 57) were defined by having no records of hospitalisation in the Swedish Hospital Discharge Register during a time period of 33.4 ± 3.9 years between baseline (1974–1992) and the end of follow-up (31st of December 2014). They were compared to subjects with unhealthy severe obesity (USO; n = 752), as well as age- and sex-matched non-obese controls (n = 1618). Results: Subjects with HSO had a significantly lower GRS DM2 (HSO 40.4 ± 3.7 vs. USO 41.8 ± 3.8, p = 0.007). Compared to subjects with USO, the HSO subjects reported significantly more leisure-time physical activity, PA (p = 0.016). There were no significant differences between HSO and USO subjects in the distribution of fat mass or obesity-associated gene phenotypes (FTO gene; variant rs9939609; p = 0.8). Conclusion: Higher PA and lower GRS DM2 might be protective factors against all-cause hospitalisation in subjects with severe obesity. These findings support the concept of HO being fat but fit. Still, it remains unclear whether higher PA is causally related to HSO, and which role environmental factors such as PA play in the interaction with genetic factors such as GRS DM2.
