70 female subjects who had attempted to lose weight responded to Rotter's I-E Scale and to a linear scale indicating their success in weight reduction. They also indicated whether they had ever joined an organized weight-reduction program and, if so, whether they had completed it. On the basis of their responses they were classified as Externals or Internals and as Joiners or Non-joiners producing four groups in a 2 × 2 factorial design. The groups were External Joiners, External Non-joiners, Internal Joiners and Internal Nonjoiners. The perceived locus of control did not affect self-rating scores of weight reduction. Nor did membership status affect ratings of success. An interaction between perceived locus of control and membership status was found. Internal Joiners reported greater success in weight loss than Internal Non-joiners. External subjects, however, reported greater success in weight reduction when they did not join a weight-reduction program. The least successful group in weight loss was composed of Joiners who dropped out of a program before its completion.

Obese Subjects

Background. In clinical practice, there is the diffuse conviction that obese subjects with metabolic syndrome may be more difficult to treat. Objectives and Methods. The aim of the present study was that to investigate the effectiveness of a 3-week in-hospital body weight reduction program (BWRP) in a large population of obese subjects with and without metabolic syndrome (n = 1922; 222 men and 1700 women, age range 18–83 yr). Outcomes such as body mass index (BMI), total (TOT) and HDL cholesterol, systolic and diastolic blood pressures (SBP and DBP, respectively), coronary heart disease (CHD) score, fatigue severity score (FSS), and stair climbing test (SCT) time were evaluated before and after the intervention (Δ). A sex-, BMI-, and age-related stratification of the obese population with or without metabolic syndrome was applied. Results. When compared to obese subjects without metabolic syndrome, at the basal conditions, obese subjects had a poorer cardiometabolic profile, as demonstrated by higher triglycerides, TOT-cholesterol, DBP, SBP, and CHD score, and a more compromised muscle performance (evaluated by SCT), associated with more perception of fatigue (measured by FSS). Nevertheless, obese subjects with metabolic syndrome obtained more benefits from BWRP than those without metabolic syndrome for some outcomes (i.e., ΔTOT-cholesterol, ΔSBP, and ΔCHD score). Despite these differences, the BWRP-induced weight loss was similar between the two groups (i.e., ΔBMI) as well as the gain of muscle performance (i.e., ΔSCT) and the reduction of fatigue (i.e., ΔFSS). Interestingly, the potentially deleterious fall in HDL-cholesterol levels after BWRP was less evident in obese subjects with metabolic syndrome than those without metabolic syndrome. When pooling all data, the ΔCHD score was associated with age, sex, and metabolic syndrome. The remaining outcomes, such as ΔBMI, ΔFSS, and ΔSCT time, were associated with sex and age but not with metabolic syndrome. Finally, ΔBMI was positively correlated with ΔCHD score, ΔFSS, and ΔSCT time in both obese subjects without metabolic syndrome and obese subjects with metabolic syndrome. Conclusions. When comparing obese subjects undergoing a BWRP, metabolic syndrome is not a negative predictive factor affecting the effectiveness of this intervention in terms of weight loss, muscle performance, and psychological well-being.

♦ Objectives Patients on peritoneal dialysis (PD) are exposed to glucose-based dialysate solutions with consequent risk of obesity and its attendant health problems. We wished to examine the role of changes in dialysis prescription, individualized dietary input, and exercise on body weight and composition. ♦ Design A 1 year, prospective interventional study integrating the care of the renal nurse, dietitian, and physiotherapist to support, educate, and encourage overweight patients on PD in a weight-reduction program. ♦ Patients Patients were considered for the study if they had been on PD for more than 3 months, had a body mass index (BMI) > 25, and were considered medically fit to undergo the planned exercise program. Recruitment was intentionally limited to a maximum of 12 patients to facilitate group interaction. Weight, BMI, and bioimpedance were measured every 3 months. ♦ Results 8 of 11 enrolled patients completed the study; 3 received transplants. There was a significant fall in median body weight at initiation, from 94.6 kg to 92.4 kg at 6 months and 89.5 kg at 12 months ( p = 0.017). This equates to a reduction in BMI from 33.2 (range 26.6 – 38.4) kg/m2 at initiation to 32.1 (range 24.5 – 37.6) kg/m2 at 6 months and 32.1 (range 23.9 – 36.5) kg/m2 at 12 months. There were no significant changes in total body water, lean body mass, or percentage body fat during the study. ♦ Conclusion 7 of 8 patients achieved significant weight loss during the study. The use of an informal group setting motivated patients to continue with exercise and sensible eating patterns. This study demonstrates that, with adequate support, PD patients can achieve and maintain weight loss.

The Impact

Among the factors influencing weight loss and maintenance, psychobehavioral, nutritional, metabolic, hormonal and hereditary predictors play an important role. Psychobehavioral factors influence adherence to lifestyle changes and thus weight loss maintenance. The outcome of short-term weight reduction treatment is mainly affected by changes in energy and nutrient intake and physical activity and thus the impact of hormones can possibly be obscured. In order to reveal hormonal determinants of weight loss, a 4-week in-patient comprehensive weight reduction program was introduced in which food intake and physical activity were under the strict control. Women (n = 67, BMI: 32.4+/-4.4 kg; age: 48.7+/-12.2 years) who exhibited stable weight on a 7 MJ/day diet during the first week of weight management were given a hypocaloric diet yielding daily energy deficit 2.5 MJ over the subsequent 3-week period. This treatment resulted in a mean weight loss of 3.80+/-1.64 kg. Correlation analysis revealed that baseline concentrations of several hormones were significantly associated either with a higher (free triiodothyronine, C-peptide, growth hormone, pancreatic polypeptide) or with a lower (insulin-like growth factor-I, cortisol, adiponectin, neuropeptide Y) reduction of anthropometric parameters in response to weight management. In a backward stepwise regression model age, initial BMI together with baseline levels of growth hormone, peptide YY, neuropetide Y and C-reactive protein predicted 49.8 % of the variability in weight loss. Psychobehavioral factors (items of the Eating Inventory, Beck Depression score) did not contribute to weight change induced by a well-controlled short-term weight reduction program.
