Obesity Science & Practice, 2019
Objective: Research suggests that individuals seeking weight loss treatment do so for a variety of reasons. Limited work has explored relations of reasons for weight loss to patient characteristics or to weight loss outcomes. The current study examined these relations. Methods: The sample consisted of 588 patients in a 15-week fee-for-service weight loss programme. Prior to the intervention, patients completed questionnaires including items on reasons for weight loss, demographic characteristics, and a variety of weight-based characteristics. Patients' weight change outcomes were expressed as percent weight loss and also categorized into one of three previously described weight loss trajectories. Results: The results of chi-squared and t-test analyses suggested that endorsement of health concerns, mobility concerns, or another person's recommendation was associated with higher body mass index (BMI) and older age. These reasons were more likely to be endorsed by White patients than Black patients and by male patients than female patients. Endorsement of doctor recommendation was more likely to be seen among Black patients than White patients. There was no significant relation of any weight loss reason with weight loss outcome. Conclusions: While certain reasons for weight loss were more often cited by certain patient groups, no specific reason predicted a better or worse outcome.
Weight loss and health-related quality of life: Results at 1-year follow-up
Eating Behaviors, 2004
To evaluate the 1-year results of treatment-induced weight loss on health-related quality of life (HRQL), 32 mildly to moderately overweight persons who participated in a 13-week weight loss program completed the Medical Outcomes Study Short Form-36 Health Survey (SF-36) at baseline, immediately after the program, and at 1-year follow-up. At 1 year, 65.6% of participants maintained at least some weight loss. The improvements on HRQL observed immediately after treatment on the physical functioning, role-physical, general health, vitality, and mental health scales of the SF-36 were maintained only on the general health and vitality scales at 1 year. There were no significant differences between weight maintainers and weight regainers on change from baseline to 1year follow-up on HRQL. Our findings suggest that treatment-induced weight loss among mildly to moderately overweight persons improves HRQL and that at least some of these benefits are maintained at 1-year follow-up regardless of whether the weight loss is maintained.

Weight Loss During the Intensive Intervention Phase of the Weight-Loss Maintenance Trial
American Journal of Preventive Medicine, 2008
Background-To improve methods for long-term weight management, the Weight Loss Maintenance (WLM) trial, a four-center randomized trial, was conducted to compare alternative strategies for maintaining weight loss over a 30-month period. This paper describes methods and results for the initial 6-month weight-loss program (Phase I).
The correlates of long term weight loss: a group comparison study of obesity
OBJECTIVE: Although the majority of weight loss attempts are unsuccessful, a small minority succeed in both weight loss and maintenance. The present study aimed to explore the correlates of this success. METHOD: A group comparison design was used to examine differences between women who were classi®ed as either weight loss maintainers (had been obese (body mass index, BMI 30 kgam 2 ) and had lost weight to be considered non-obese (BMI`30 kgam 2 ) and maintained this weight loss for a minimum of 3 y; n 44), stable obese (maintained an obese weight (BMI 30 kgam 2 ) for longer than 3 y; n 58), and weight loss regainers (been obese (BMI 30 kgam 2 ), lost suf®cient weight to be considered non-obese (BMI`30 kgam 2 ) and regained it (BMI 30 kgam 2 ), n 40). In particular, the study examined differences in pro®le characteristics, historical factors, help-seeking behaviours and psychological factors. RESULTS: The results showed that in terms of pro®le and historical factors, the weight loss maintainers had been lighter, were currently older and had dieted for longer than the other groups but were matched in terms of age, class and ethnic group. In terms of help-seeking behaviours, the weight loss maintainers reported having tried healthy eating more frequently but were comparable to the other subjects in terms of professionals contacted. Finally, for psychological factors the weight loss maintainers reported less endorsement for medical causes of obesity, greater endorsement for psychological consequences and indicated that they had been motivated to lose weight for psychological reasons. CONCLUSIONS: Weight loss and maintenance is particularly correlated with a psychological model of obesity. This has implications for improving the effectiveness of interventions and the potential impact of current interest in medical approaches to obesity.
Health and Quality of Life Outcomes, 2009
The literature on changes in health-related quality of life (HRQOL) in weight loss studies is inconsistent, and few studies use more than one type of measure. The purpose of the current study was to compare one-year changes in HRQOL as a function of weight change using three different measures: a weight-related measure (Impact of Weight on Quality of Life-Lite [IWQOL-Lite)]) and two generic measures (SF-36; EQ-5D).
Characteristics of Weight Loss Trajectories in a Comprehensive Lifestyle Intervention
Obesity (Silver Spring, Md.), 2017
Focusing on average weight loss (WL) from interventions provides useful efficacy data but masks large variability across patients. In this study, parameters of weight loss trajectories were determined that differentiated individuals during a 15-week clinical lifestyle intervention. Patients (n = 595) were in a fee-for-service WL lifestyle program with a partial meal replacement diet and lifestyle change counseling. Parameters used in latent class analyses were percent WL (%WL), weight nadir, number of weekly weight gains, maximum weekly percent weight gain, standard deviation of weekly weight changes, linear slope values, and change in slope. Average %WL was 9.73%. Latent class analyses revealed three groups with considerable overlap in %WL ranges but differing significantly on all trajectory parameters (Ps < 0.001). Group 1 had the most variable and least successful pattern of weight changes. Group 3 had the least variable and most successful pattern of weight changes. Group 2 f...

Despite a growing literature on the efficacy of behavioral weight loss interventions, we still know relatively little about the long terms effects they have on HRQL. Therefore, we conducted a study to investigate the immediate post-intervention (6 months) and long-term (12 and 24 months) effects of clinically based weight management programs on HRQL. We conducted a randomized clinical trial in which all participants completed a 6 month clinical weight loss program and were randomized into two 6-month extended care groups. Participants then returned at 12 and 24 months for follow-up assessments. A total of 144 individuals (78% women, M age = 50.2 (9.2) yrs, M BMI = 32.5 (3.8) kg/m2) completed the 6 month intervention and 104 returned at 24 months. Primary outcomes of weight and HRQL using the SF-36 were analyzed using multivariate repeated measures analyses. There was complete data on 91 participants through the 24 months of the study. At baseline the participants scored lower than U...
Eating and Weight Disorders - Studies on Anorexia, Bulimia and Obesity, 2014
Purpose Weight loss treatment effectiveness and costeffectiveness may be improved by the identification of patients who are more prone to participate and gain benefit from specific interventions. Aim of the present study is to identify easily available additional predictors of weight loss among data usually present in the medical records of obese/overweight patients attending an outpatient clinic for a non-pharmacological lifestyle change program. Results 268 patients, 74 men and 195 women (age 43.2 ± 11.9 years, BMI 38.9 ± 6.8 kg/m 2) were enrolled. Among these patients, only 35.6 % men and 22.7 % women completed the 6-month protocol. Among participants, 50.7 % lost at least 5 % initial body weight after 6 months (SUCCESSES), while 49.3 % failed (FAIL-URES). Baseline nutritional parameters (total Kcal, lipid, carbohydrate, protein and alcohol intake) were not significantly different in successes when compared to failures, while a significant difference between groups was observed for baseline diastolic blood pressure (DBP); free fat mass (FFM); muscle mass (MM); total body water (TBW); HDL cholesterol; ALT; AST; cGT. After dividing into quartiles the not-normally distributed variables, successes had AST values above median (3rd and 4th quartiles; v 2 = 0.003). At multivariate analysis (linear regression), the OR was 3.34 (1.42-7.85; p = 0.006). Conclusions In our patients, baseline liver enzyme levels (AST in particular), but not baseline quantitative and qualitative dietary intake, were significantly different in successes versus failures and could therefore represent a predictor of success. In conclusion, AST could represent a usually available biomarker that could be used as a predictor of outcome (weight loss) in obese patients starting a lifestyle change program.
