Type 2 diabetes mellitus (T2DM) is a chronic metabolic disorder exacerbated by obesity. Single Anastomosis Sleeve-Ileal Bypass (SASI) has emerged as a promising metabolic bariatric procedure that combines sleeve gastrectomy and ileal bypass, facilitating substantial weight loss and T2DM remission through restrictive and malabsorptive mechanisms. This study aims to evaluate the effects of SASI on T2DM remission, weight loss, and safety in one year follow-up. A retrospective cohort study analyzed 31 patients with obesity and T2DM who underwent SASI. Data collected included demographic characteristics, preoperative and postoperative BMI, HbA1c levels, and bariatric outcomes, including %TWL and T2DM changes. The mean age was 45 years, with a mean preoperative BMI of 40.7 kg/m². One year postoperatively, the mean %EWL was 85.6% and %TWL was 31.7%. T2DM remission was achieved in 24 (77.4%) patients, improvement in 4 (12.9%), and no change in 3 (9.7%). Hypertension improved in 21 (87.5%) patients, with 12 (50%) achieving remission. Significant reductions in BMI and HbA1c levels were observed (p < 0.001). Responders (R) and non-responders (NR) groups showed significant differences in postoperative BMI and %EWL (p = 0.007, p = 0.023). One patient experienced a Clavien-Dindo Grade III complication; no deaths occurred. SASI is an effective and safe procedure for treating T2DM, resulting in significant weight loss and metabolic improvements over a one-year follow-up. SASI seems to be a favorable option for T2DM management in metabolic bariatric surgery., (© 2024. The Author(s).)

Purpose: A combined body weight loss and upper body/arm exercise programme is a potential strategy for managing Breast cancer related lymphoedema (BCRL), but there is limited data on the best method for delivery or its potential efficacy., Methods: Fifty-seven women with overweight/obesity and BCRL were randomised to a 12 week supervised (n = 12) or home-based combined weight loss and upper body/arm exercise programme (n = 16), a home-based upper-body arm exercise only programme (n = 17) or standard care (n = 12). Primary outcomes were uptake, retention and changes in weight and change in Relative Arm Volume Increase (RAVI) using analysis of covariance (ANCOVA)., Results: Sixteen percent of women invited joined the study and 49 completed the trial (85% retention). Reductions in weight occurred in the supervised and home-based weight control and exercise programmes; Mean (95% CI) change compared to standard care - 1.68 (- 4.36 to - 1.00), - 2.47(- 4.99 to - 0.04) Kg. Reductions in perometer assessed RAVI were seen in the supervised and home-based combined weight control and arm exercise groups and the weight stable home-based arm exercise only group: mean (95% CI) change compared to standard care - 2.4 (- 5.0 to + 0.4),- 1.8 (- 4.3 to + 0.7), - 2.5(- 4.9 to - 0.05)%., Conclusion: Women with BCRL and overweight and obesity engaged in diet and exercise weight loss programmes. Both weight loss/arm exercise programmes led to modest changes in weight and BCRL. Comparable reductions in BCRL were reported in the weight stable group undertaking arm exercise only. The independent and combined effects of weight loss and exercise on BCRL need further study., Trial Registration: ISRCTN86789850 https://doi.org/10.1186/ISRCTN86789850 , registered 2011., (© 2024.

Objective: This study explored the relationship between unhealthy weight control behaviors (UWCBs) and their associated economic costs among adolescents using the 2014-2018 Longitudinal Study of Australian Children (LSAC)., Methods: LSAC data in Wave 6 (n = 3538 adolescents aged 14-15 years), Wave 7 n = 3089 adolescents aged 16-17 years), and Wave 8 (n = 3037 adolescents aged 18-19 years) were derived from a representative sample of Australian adolescents. UWCBs were measured using the self-reported Branched Eating Disorder Test questionnaire. UWCBs were sub-classified into having fasting behaviors, using weight loss supplements or purging behaviors. Economic costs include healthcare and productivity costs to caregivers. Healthcare costs were measured using data from the Medicare and Pharmaceutical Benefits, which includes both medical and pharmaceutical costs. Productivity losses were measured using caregivers' lost leisure time due to UWCBs among adolescents., Results: The mixed effect model identified statistically significant higher economic costs (mean difference = $453, 95% CIs $154, $752), higher health care costs (mean difference = $399, 95% CIs $102, $695), and higher productivity costs (mean difference = $59, 95% CIs $29, $90) for adolescents with UWCBs compared to their peers with no UWCBs. Subgroup analysis revealed that higher costs were associated with fasting and purging behaviors., Discussion: UWCBs were associated with increased economic costs during adolescence. Our finding suggests there should be a policy focus on tackling UWCBs to reduce the economic burden on the healthcare system and society., Public Significance: The study contributes to existing knowledge by investigating the direct healthcare costs and productivity losses associated with unhealthy weight control behaviors in Australian adolescents (14-18 years old) using a dataset that follows Australian adolescents over time. We found that engaging in unhealthy weight control behaviors such as fasting, using weight loss supplements, and purging was linked to higher costs among adolescents, suggesting policies should focus on addressing these behaviors., (© 2023 The Authors.

Diabetes mellitus is one of the major epidemics in the United States. It is heavily associated with obesity and multiple metabolic derangements that lead to long term morbidity, mortality as well as financial burden. Although medical therapy has been the mainstay in the management of diabetes mellitus, there remains a large portion of this patient population which struggles to obtain adequate glycemic control and long-term weight control with medical management alone. Bariatric surgery is a powerful tool in combating diabetes mellitus and affects glucose homeostasis through a variety of pathways. While it does provide a durable pathway for weight loss, improvement in glucose homeostasis is not only affected by the weight loss seen after bariatric surgery. Changes in gut hormone secretion, insulin regulation, and gut microbial composition also affect how these operations improve glucose homeostasis. Through improvement in the management of diabetes mellitus, comorbidities including cardiovascular disease, in turn demonstrate improvement. In this article, we will discuss the role of bariatric (metabolic) surgery as it relates to long term weight loss and the impact that weight loss has on improvement in diabetes mellitus., Competing Interests: Declaration of Competing Interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2023 Elsevier B.V.

Background: Personalizing approaches to prevention and treatment of obesity will be a crucial aspect of precision health initiatives. However, in considering individual susceptibility to obesity, much remains to be learned about how to support healthy weight management in different population subgroups, environments and geographical locations., Subjects/methods: The International Weight Control Registry (IWCR) has been launched to facilitate a deeper and broader understanding of the spectrum of factors contributing to success and challenges in weight loss and weight loss maintenance in individuals and across population groups. The IWCR registry aims to recruit, enroll and follow a diverse cohort of adults with varying rates of success in weight management. Data collection methods include questionnaires of demographic variables, weight history, and behavioral, cultural, economic, psychological, and environmental domains. A subset of participants will provide objective measures of physical activity, weight, and body composition along with detailed reports of dietary intake. Lastly, participants will be able to provide qualitative information in an unstructured format on additional topics they feel are relevant, and environmental data will be obtained from public sources based on participant zip code., Conclusions: The IWCR will be a resource for researchers to inform improvements in interventions for weight loss and weight loss maintenance in different countries, and to examine environmental and policy-level factors that affect weight management in different population groups. This large scale, multi-level approach aims to inform efforts to reduce the prevalence of obesity worldwide and its associated comorbidities and economic impacts., Trial Registration: NCT04907396 (clinicaltrials.gov) sponsor SB Roberts; Tufts University IRB #13075., (© 2022.

Lifestyle and physical characteristics affect body weight, and understanding these factors improves the precision of weight loss treatment. Many obese patients in Korea are receiving Korean medicine (KM) treatment, including herbal medicine and acupuncture, for weight loss. However, the real-world data (RWD) are insufficient in terms of being longitudinal and diverse. Weight Control Registry using KM is a prospective registry study that enrolls patients receiving KM treatment for weight loss and collects RWD from multiple clinics. The patients who are eligible for this study are aged 19-65 years, receive KM weight loss treatment, understand the study objectives, and consent voluntarily. Clinical data of patient characteristics and KM treatment patterns will be regularly collected until 2026. The longitudinal accumulation of various RWD will establish a high-quality study database for KM weight loss treatment. With this study, we expect to contribute to understanding the current trend of weight loss treatment with KM and solve further questions regarding this treatment.

The study examined the effect of a weight control intervention on BMI, physical activity levels, and psychological variables toward physical activity. Thirty-three middle-aged obese women participated in the 16-week weight control intervention. Results indicated that the participants' BMI significantly decreased and physical activity levels significantly increased over the intervention. Moreover, exercise self-efficacy and perceived benefits toward physical activity significantly increased, but perceived barriers of physical activity gradually decreased over the intervention. The study suggests that it is important to consider not only physical activity itself, but also the various psychological variables when planning and implementing the weight control program.

Purpose of Review: Restrictive diets, such as low-calorie diets, are difficult to maintain in the long term. For this reason, their popularity has decreased compared to non-restrictive approaches, which instead promote healthy eating strategies. Since both strategies may entail different neurobiological mechanisms, this review will examine the current evidence on the effects of restrictive and non-restrictive interventions on neurobehavioral factors., Recent Findings: Restrictive diets appear to improve eating behaviors, and the evidence reviewed argues against the notion that they may worsen the severity of binge eating. Moreover, they may lead to short-term changes in brain structure and improvements in cerebrovascular markers which, in turn, could impact eating behaviors. Non-restrictive interventions may have a positive effect on weight management and eating behaviors. However, evidence of their neural effects is scarce. Small sample sizes, short follow-ups, and the absence of control groups are limitations of the studies targeting both interventions. Rigorous long-term randomized studies are needed to examine the neurobehavioral effects of restrictive and non-restrictive approaches., (© 2021.

Background: Overweight or obesity is common in endometrial cancer (EC). This study aimed to examine sociodemographic, clinical, and psychosocial characteristics associated with being discontent with current weight and use of weight control methods among long-term EC survivors., Methods: Women diagnosed with early-stage EC who participated in the Laparoscopic Approach to Cancer of the Endometrium (LACE) trial (n = 516) were invited to complete a long-term follow-up survey at least 4.5 years after treatment. Chi-square test and multivariate logistic regression models adjusted for time since surgery were used to determine factors associated with being discontent with current weight., Results: On average 9 years after surgery, 190/259 (73%) of participants were currently discontent with their weight, and 146 (56%) had used one or more weight loss methods during the past 12 months. Women who were discontent with their weight were more likely to be younger than 70 years (p < 0.000), and used one or more weight loss methods ever or during the past 12 months (p < 0.000). Among the weight loss methods used, exercise (40.1%), meal reductions (52.7%), or fat/sugar reductions (48.5%) were much more commonly reported than fasting (2.6%) or designated weight loss programs (2.3%)., Conclusions: Our study provides evidence that the majority of long-term EC survivors in this clinical trial population are discontent with their weight and over half continue to use multiple methods to lose weight each year. These data indicate that health professionals and lifestyle educators need to assess weight issues, and develop a tailored plan to address the specific needs of long-term survivors to assist them become content with their weight after treatment for EC., (© 2021 The Authors.

Background: Weight control is a widespread phenomenon among young adults, especially in women., Aim: This study aimed to determine the prediction factors of weight control intention in a young Chinese sample., Methods: A cross-sectional study was conducted with 963 (276 male and 687 female; mean age 21.8 ± 4.4 years) adult students from a university in Taiwan. The data were collected from October 2016 to January 2017. Body mass index (BMI), the Chinese version of the Weight Self-Stigma Questionnaire, the Body Areas Satisfaction Scale and the Media Influence Questionnaire were used as data collection instruments., Results: The participants with weight control intention had higher BMI, weight self-stigma and media influence scores and lower body satisfaction scores than those without the intention. Female sex, BMI, weight self-stigma, body satisfaction and media influence were significant predictors of weight control intention for all participants., Conclusion: Before conducting weight loss programmes, the perception of weight self-stigma and the influence of social media on body image should be confirmed, particularly in women with intention to lose weight., (© 2021 John Wiley & Sons Australia, Ltd.)

Abstract Background Misperceptions about obesity is common among adolescents. Adolescents who overestimate their body size tend to indulge in extreme weight control behaviors. However, little is known about the factors involved in the adoption of extreme weight control behavior (EWCB) by non-obese adolescents who are mistaken for being overweight. This study identified factors associated with unhealthy behaviors among normal/underweight high school students who overestimate their body image and attempt to lose weight. Design A secondary analysis of nationally representative data from the Korea Youth Risk Behavior Survey focused on adolescents who attended vocational and academically oriented high schools. Methods The analysis included data from 4,286 non-obese respondents (15–18 years) who overestimated their body weight. Of them, 2,887 were girls (66.5%), while 1,399 were boys (33.5%). Multiple logistic regression was used to investigate risk factors for EWCB by sex. A statistical analysis reflecting strata, clusters, and weights of the complex sampling design was adopted. Results Of the respondents, 674 (23.3%) girls and 162 (11.5%) boys reported EWCB. For both sexes, vocational high school attendance and depression were significantly influenced by EWCB. EWCB was linked to perceived stress in girls and living in a big city in boys. Conclusions The findings suggest the importance of providing quality health education, including that for non-obese adolescents, in school obesity prevention programs along with the expansion of tailored intervention programs based on sex, following a consideration of the characteristics of high schools as well as individuals.

Growing data from epidemiological studies highlight the association between excess body fat and cancer incidence, but good indicative evidence demonstrates that intentional weight loss, as well as increasing physical activity, offers much promise as a cost-effective approach for reducing the cancer burden. However, clear gaps remain in our understanding of how changes in body fat or levels of physical activity are mechanistically linked to cancer, and the magnitude of their impact on cancer risk. It is important to investigate the causal link between programmes that successfully achieve short-term modest weight loss followed by weight-loss maintenance and cancer incidence. The longer-term impact of weight loss and duration of overweight and obesity on risk reduction also need to be fully considered in trial design. These gaps in knowledge need to be urgently addressed to expedite the development and implementation of future cancer-control strategies. Comprehensive approaches to trial design, Mendelian randomisation studies and data-linkage opportunities offer real possibilities to tackle current research gaps. In this paper, we set out the case for why non-pharmacological weight-management trials are urgently needed to support cancer-risk reduction and help control the growing global burden of cancer.

Objectives: Family factors may play a role in adolescents' weight-control behaviours (WCB), and economic determinants strongly affect adolescents' health in terms of unhealthy weight-control behaviours (UWCB). This study examines the nexus of socioeconomic status, perceived family wealth, and number of employed parents and Israeli adolescents' WCB and asks whether family-related variables mediate WCB., Methods: Data from the 2014 Israeli Health Behaviour in School-Aged Children study are analysed using structural equation modelling., Results: High family affluence and high perceived family wealth are negatively associated with UWCB. Having two employed parents related to lower levels of UWCB. Family-related variables such as family communication and support and parental monitoring mitigate UWCB. Family meals have a significantly positive effect on healthy weight-control behaviour (HWCB) and a significantly negative impact on unhealthy weight-control activities., Conclusions: The findings suggest that economic factors such as socioeconomic status and number of employed parents should be taken into account in long-term weight-control practice. The combination of WCB and family meals is the most effective method for adolescents' healthy weight-control behaviour.

Background: A WW (formerly Weight Watchers) program adapted for persons with type 2 diabetes mellitus (T2DM) previously was found to be more effective than standard care (SC) intervention for weight loss, improved glycemic control, and weight- and diabetes-related quality of life measures. With data from the same national trial, this study examined whether WW adapted for persons with T2DM also increased engagement in weight control behaviors and decreased hedonic hunger, each of which could contribute to improved diabetes management., Intervention and Methods: Individuals with T2DM (n = 563) and overweight or obesity participated in a 12-month, 16-site, randomized trial of WW with diabetes counseling or SC. Hierarchical linear modeling (HLM) evaluated whether 12-month changes in weight control behaviors (Eating Behavior Inventory; EBI) and hedonic hunger (Power of Food Scale; PFS) differed by treatment condition. If a significant treatment effect was found, 12-month changes in EBI/PFS were regressed on 12-month changes in HbA 1c and percent weight loss to explore potential treatment differences in these associations., Results: EBI scores increased significantly over the 12-months (p < 0.001), with greater improvements in WW than SC (p < 0.001). PFS decreased significantly in the 12-months (p < 0.001), with no differences between treatment groups (p = 0.15). HLM analyses that followed up on the significant treatment effect for 12-month change in EBI revealed no significant differences by treatment condition for the relationship between change in EBI scores and change in HbA 1c (p = 0.14) or percent weight loss (p = 0.32). Across all participants, 12-month improvements in EBI and PFS were related to improved HbA 1c (r = 0.22; -0.13, respectively) and greater percent weight loss (r = 0.41; -0.18, respectively) (ps < 0.01)., Conclusions: WW with diabetes counseling produced greater engagement in weight control behaviors in those with T2DM than did SC. Across both groups, improved weight control behaviors and hedonic hunger were related to improved glycemic control and weight loss.

Introduction: Evidence is still scarce regarding the use of e-cigarettes by young people for weight-control reasons. This study aimed to test a model in which the prospective association between negative body esteem and e-cigarette use is mediated by weight-control outcome expectancies for e-cigarette use. The model was tested across genders., Methods: Data were collected at three time points, 6 months apart, from 2327 young adults (mean age = 21.2; SD = 2.2; 54% women). Self-reported data were collected on demographics, body mass index, body esteem, weight-control outcome expectancies for e-cigarette use, and current e-cigarette use and cigarette smoking., Results: Among women, we found a significant indirect effect of lower body esteem on higher likelihood of current e-cigarette use 1 year later, mediated by higher weight-control outcome expectancies at 6-month follow-up, adjusting for demographics, body mass index, and baseline e-cigarette use and cigarette smoking. Among men, body esteem was not found to have significant effect on either weight-control expectancies or e-cigarette use., Conclusions: Based on the current findings, young adult women who have higher negative body esteem are at increased risk for using e-cigarettes for weight-control motives., Implications: The current findings are some of the first to show prospective associations among weight-control motives and e-cigarette use among young adults. These findings suggest that a group of vulnerable young women may be using e-cigarettes to lose or control weight. More research is needed to understand their choice of flavors, nicotine concentration, and device type. In addition, research is needed to understand whether e-cigarettes are being marketed, directly or indirectly, as being useful for weight loss or control. There may be a need for health promotion strategies that provide healthier alternatives to young women struggling with low body esteem who use e-cigarettes for weight loss or control., (© The Author(s) 2020.

Background: Weight loss is critical for preventing and managing obesity-related diseases. There is a notable lack of valid and reliable means to manage patients with overweight/obesity and knee osteoarthritis (KOA)., Objective: To determine the efficacy and safety of liraglutide in a 30 mg/d dosing in patients with overweight/obesity and KOA., Methods: The trial was designed as a randomized controlled trial including patients between the age of 18 and 74 y with KOA and a BMI ≥27 (measured in kg/m2).Patients underwent a pre-random assignment diet intervention (week -8 to 0). At week 0, patients having lost >5% of their body weight were randomly assigned to liraglutide 3 mg/d or placebo for 52 wk. The coprimary outcomes were changes in body weight and the Knee injury and Osteoarthritis Outcome Score (KOOS) pain subscale from week 0 to 52., Results: In total, 168 patients enrolled and 156 were randomly assigned to receive liraglutide or placebo. Patients experienced a significant reduction in body weight and KOOS pain during the pre-random assignment dietary intervention period (week -8 to 0). From week 0 to 52 there was a significant difference in body weight between the liraglutide and placebo group (mean changes: -2.8 and +1.2 kg, respectively; group difference, 3.9 kg; 95% CI: -6.9, -1.0; P = 0.008). There was, however, no group difference in KOOS pain (mean changes: 0.4 and -0.6 points, respectively; group difference, 0.9 points; 95% CI: -3.9, 5.7; P = 0.71). Treatment-emergent adverse events related to the gastrointestinal system were experienced by 50.2% and 39.2% of patients in the liraglutide and placebo groups, respectively., Conclusions: In patients with KOA and overweight/obesity liraglutide added after an 8-wk pre-random assignment diet induced a significant weight loss at >52 wk but did not reduce knee pain compared to placebo. This trial was registered at clinicaltrials.gov as NCT02905864., (© The Author(s) 2021. Published by Oxford University Press on behalf of the American Society for Nutrition.)

Objectives: The objective is to determine association of age, gender, BMI, body image (body satisfaction, body appearance), depression, unhealthy weight control behaviors with smoking among Serbian adolescents and specifically association of these variables with smoking for weight control among adolescent smokers., Methods: This is a secondary analysis of data collected from 2763 students aged 13-15 years old (49.9% boys; 50.1% girls) obtained through cross-sectional Health Behavior in School-aged Children Survey conducted in Serbia in 2018 and analyzed using multivariable logistic regression., Results: In Serbia, 12.9% adolescents 13-15 years old smoke and 6.6% smoke for weight control, while this practice was present among 48.8% of the smokers. Higher odds of smoking were found among adolescents who perceive themselves thin and good looking, while these two factors didn't play role for the smoking for weight control among smokers. Depression and unhealthy weight control behavior other than smoking significantly predicted smoking and smoking for weight control. Gender was not associated with smoking in adolescents, but among adolescent smokers, boys had two times higher chance compared to girls to report smoking for weight control., Conclusions: Findings call for incorporating and strengthening interventions for adolescents' weight control management and mental health as part of smoking prevention and cessation programs.

We hypothesized that exposure to weight stigma simultaneously increases motivation to lose or avoid gaining weight to avoid future stigma and decreases perceived capacity to do so, by heightening concerns about experiencing stigma and negative affect. Study 1 showed that more frequently experiencing weight-based discrimination was associated with greater concerns about being a victim of weight stigma, which predicted increased motivation to lose weight but decreased perceived capacity for weight control. Study 2 showed that participants randomly assigned to view a weight-stigmatizing (vs. control) message showed increased concerns about being a target of weight stigma, which indirectly increased motivation to lose weight and decreased state self-control. These, in turn, predicted increased willingness to engage in unhealthy weight-loss behaviors and decreased perceived capacity for weight control, respectively. Study 3 showed that increased motivation to avoid stigma and increased negative affect mediate these effects of exposure to weight stigma.

Randomized controlled trials, being published in English and investigating the associations of at least 4 weeks intervention of citrus and/or its extracts on weight loss among adults, were searched from PubMed, Web of Science, Scopus, and Cochrane by June 2019 to conduct a meta-analysis. Thirteen articles, including 921 participants, were selected and evaluated by modified Jadad scale. Pooled results by the random-effects model showed that citrus and/or its extracts administration significantly reduced 1.280 kg body weight (95% CI: -1.818 to -0.741, p = 0.000, I 2 = 81.4%), 0.322 kg/m 2 BMI (95% CI: -0.599 to -0.046, p = 0.022, I 2 = 87.0%), 2.185 cm WC (95% CI: -3.804 to -0.566, p = 0.008, I 2 = 98.3%), and 2.137 cm HC (95% CI: -3.775 to -0.500, p = 0.011, I 2 = 96.2%), respectively, but no significantly decreased effects on WHR and body fat were observed. Subgroup analysis deduced the different effects of study location, intervention duration on body weight associated indices. No publication bias was observed. Our meta-analysis supported the beneficial effects of citrus and/or its extracts supplement on body weight control, and future well-designed studies are required to firmly establish the clinical efficacy of citrus and/or its extracts intervention on body weight., (© 2020 John Wiley & Sons, Ltd.)

Background: Hypothalamic obesity causes unrelenting weight gain for childhood brain tumor survivors. No single therapy has proven effective for treatment. We aimed to evaluate effectiveness of long-term methylphenidate therapy on body mass index (BMI) change in children with hypothalamic obesity., Methods: A retrospective analysis included children with a history of brain tumor and hypothalamic obesity receiving methylphenidate (10-60 mg/day) for hypothalamic obesity. Subjects were evaluated for BMI trajectory before and after methylphenidate start. Given that z-scores can be skewed in severely obese children, we calculated BMI as a percent of the BMI at the 95th percentile for the child's age and gender (BMI% 95th)., Results: Twelve patients with hypothalamic obesity completed methylphenidate therapy for at least 6 months (median 3.1 years, range 1.0-5.8 years). All subjects had a suprasellar tumor (nine [75%] with craniopharyngioma) and pituitary dysfunction. Pretreatment median BMI percent of the 95th percentile was 125.6% (interquartile range [IQR] 25-75: 115.3-138.3%) with BMI z-score of 2.4 (IQR 25-75: 2.1-2.6). Following methylphenidate treatment, there was a 69.9% reduction in the median slope of BMI change. Eleven of 12 patients (92%) had a reduction in the slope of their BMI change on methylphenidate treatment. Postmethylphenidate median BMI percent of the 95th percentile decrease to 115.2% (IQR 25-75: 103.6-121.2%) with median BMI z-score of 2.1 (IQR 25-75: 1.8-2.2). Mild side effects were noted in six patients., Conclusions: Methylphenidate use reduced and sustained BMI change in children with hypothalamic obesity. Stimulant therapy is an effective first-line agent for treatment of hypothalamic obesity., (© 2020 Wiley Periodicals, Inc.)

Weight loss maintenance is a major challenge for obesity treatment. Weight control registries can be useful in identifying psychological and behavioural factors that could contribute to better long-term success. The objective of this study is to describe the existing weight control registries and their participants and identify correlates of weight loss maintenance. A comprehensive search of peer-reviewed articles published until November 2018 was conducted in PubMed, Web of Science, and Scopus. Studies that reported results from weight control registries were considered. Fifty-two articles, corresponding to five registries (the United States, Portugal, Germany, Finland, and Greece), were included. Registries differed in inclusion criteria and procedures. Of 51 identified weight loss and maintenance strategies, grouped in 14 domains of the Oxford Food and Activity Behaviors taxonomy, the following were the most frequently reported: having healthy foods available at home, regular breakfast intake, increasing vegetable consumption, decreasing sugary and fatty foods, limiting certain foods, and reducing fat in meals. Increased physical activity was the most consistent positive correlate of weight loss maintenance. To our knowledge, this is the first systematic review of information about successful weight loss maintenance obtained from weight control registries. Key common influential characteristics of success were identified, which can inform future prospective studies and weight management initiatives., (© 2020 World Obesity Federation.)

Objectives. To investigate the prospective association of diet pill and laxative use for weight control with subsequent first eating disorder diagnosis in young women. Methods. We used longitudinal data from 10 058 US women spanning 2001 through 2016. We used multivariable logistic regression models, adjusting for age, race/ethnicity, and overweight status to estimate the association between weight-control behaviors and subsequent eating disorder diagnosis. Results. Among those who had not previously received an eating disorder diagnosis, women who reported diet pill (adjusted odds ratio [AOR] = 5.6; 95% confidence interval [CI] = 3.0, 10.5) or laxative (AOR = 6.0; 95% CI = 4.2, 8.7) use for weight control had higher odds of receiving a subsequent first eating disorder diagnosis within 1 to 3 years than those who did not report using these products. Conclusions. Use of diet pills or laxatives for weight loss can be dangerous and may be a warning sign that warrants counseling and evaluation for the presence of or risk of developing an eating disorder. Public Health Implications. Policymakers and public health professionals should develop and evaluate policy initiatives to reduce or prohibit access to diet pills and laxatives abused for weight control.

Overweight and obese men were recruited to a 6-month, randomized controlled weight loss trial, which compared the Gutbusters weight loss program alone to the Gutbusters program with incentives for successful weight loss. The intervention was delivered primarily online, with weekly in-person weight collections. Gutbusters was designed using a template from the REFIT intervention and encouraged participants ( N = 102, 47.0 ± 12.3 years, 32.5 kg/m 2 ) to make six 100-calorie changes to their typical daily diet for a total of 42 changes per week. Weight loss was significantly greater in the Gutbusters+Incentive group compared to the Gutbusters alone group at both 12 and 24 weeks ( p 's = < .01). The Gutbusters+Incentive group's a mean weight loss was 9.9 pounds at 12 weeks (95% CI: 6.9, 12.9) and 8.4 pounds at 24 weeks (95% CI: 3.9, 13.0). The Gutbusters alone group mean weight loss was 3.7 pounds at 12 weeks (95% CI: -.06, 7.5) and 3.4 pounds at 24 weeks (95% CI: -2.2, 9.0). This study adds to the literature of behavioral weight programs that are designed for men. Unlike the majority of previous male weight loss interventions, which were designed with an intervention comparison to a no treatment or waitlist control, Gutbusters was implemented as a comparative effectiveness trial, which will help bolster the evidence base for real-world application.

Background/objective: There are many methods for weight loss and they vary among people. Some are yet to be proven as appropriate regarding its physical or mental side effect. The aim of this study was to investigate the relationship between weight control success and depression by weight control behaviors (WCB) dividing them into appropriate and inappropriate., Subjects/methods: We used data from the 2016 Korea National Health and Nutrition Examination Survey (KNHANES). A total of 4506 people were included in the study. The depression was measured by the 9-item Patient Health Questionnaire as a dependent variable. Using multiple regression analysis to determine the association between weight control success and depression with appropriate and inappropriate WCB, in men and women, separately., Results: We found that appropriate WCB was associated with decreased depression in women who had both success and fail (success: β=-0.16, S.E=0.50, p<.001; fail: β=-0.09, S.E=0.04, p=0.04), whereas inappropriate WCB increased depression in men regardless of success or failure at weight control (success: β=0.41, p=0.02; fail: β=0.22, p=0.02). Thus, women who are successful at weight control and use appropriate WCB are more likely to have a decrease in depressive symptoms. However, men are most affected by using inappropriate WCB and can have an increase in depressive symptoms as a result., Conclusion: The findings have implications for encouraging the use of appropriate WCB for those attempting to control weight, especially in women., (Copyright © 2018.

There is extensive data supporting a high prevalence of both overweight and obesity status in people with multiple sclerosis, and increases in body mass index has been associated with an increased risk of multiple sclerosis. Body composition may influence the course, treatment and management of multiple sclerosis. One proposed strategy for managing overweight and obesity status and associated secondary effects in people with multiple sclerosis involves increasing the levels of physical activity. In fact, increased levels of physical activity affect various physiological (endurance capacity, strength, balance) and biological processes (fat oxidation, insulin sensitivity, anti-inflammation, neurotrophic factors) which are known to be dysfunctional in multiple sclerosis and which may worsen with increases in obesity. When designing personalized exercise programs it should be kept in mind that current exercise recommendations for people with multiple sclerosis should exceed energy expenditure recommendations to efficiently counteract weight gain. Therefore, it is necessary to consider body composition as a primary endpoint in experimental studies. In addition, designing guidelines for weight control or weight loss in people MS is needed. The most comprehensive weight management guidelines are outlined in the American College of Sports Medicine Position Statement, which recommends between 150-250 min per week of moderate-intensity physical activity for preventing weight gain, and between 225-420 min per week of moderate-intensity physical activity for weight loss. These recommendations seem applicable for people with multiple sclerosis., (Copyright © 2019 Elsevier Ltd. All rights reserved.)

Background: Knee osteoarthritis (OA) is a leading cause of disability among the elderly and is often exacerbated by obesity. Research supports weight loss and exercise therapy as key strategies for managing knee OA‐related disability. Concurrently, telemedicine is becoming a popular healthcare approach. This study aimed to develop and evaluate an 8‐week tele‐education programme's impact on weight control and knee OA outcomes. Methods/Design: Participants with knee OA and obesity were included. Baseline data on pain (VAS index), physical activity (GPAQ questionnaire), and quality of life (EQ5D and KOOS questionnaires) were collected. Performance tests, including the 30‐second Chair Stand test (30CST) and the Timed Up‐and‐Go test (TUG), were recorded. Participants were randomly divided into two groups: a control group receiving oral advice on diet and exercise, and an intervention group receiving educational videos on nutrition, lifestyle changes, physical activity, individualised exercises, and psychosocial support. Evaluations were repeated after 8 weeks. Results: Data from 25 of 30 participants were analysed. In the intervention group, body composition, waist, and abdominal circumference decreased significantly (p < 0.05). The KOOS questionnaire showed significant improvements in pain, activity, and daily tasks (p = 0.00). The EQ5D questionnaire and health satisfaction also showed positive results within the intervention group (p = 0.00) and between groups (p = 0.008). The pain index improved significantly within (p = 0.00) and between groups (p = 0.02). Functional test results were significant within the intervention group (p = 0.00) and between groups (p = 0.017 for 30CST and p = 0.004 for TUG). Conclusion: An 8‐week tele‐education programme for weight control and exercise therapy in knee OA patients significantly improved body composition, quality of life, and functional performance. Given the costs of obesity and knee OA on both people and the health system, tele‐education can be a cost‐effective treatment strategy. [ABSTRACT FROM AUTHOR]

Long-term successful weight control poses a huge challenge to people who are overweight and treat them in the obesogenic environment. After reaching a clinically significant (5-10%) weight loss, the goal is to maintain the weight loss achieved. However, this requires virtually constant resistance to temptations and requires sustained effort in terms of dietary restriction and physical activity, which requires a strong motivational base. From the point of view of behavior, motivation is the probability that the patient starts, pursues, or persistently follows a strategy that triggers change, that is, in the case of obesity, is committed to health-related behaviors that support weight management and abandons health risk behaviors that hinders weight control efforts. The present study describes the transtheoretical model of behavioral change and provides examples of practical ways to increase motivation and adherence at all stages of behavioral change. All this can contribute to the work of primary care and outpatient care professionals in supporting weight loss patients with excess weight. Orv Hetil. 2019; 160(43): 1687-1697.

Objective: to compare the effects of the hydroalcoholic extract from the peel of Camu-Camu, a fruit plant belonging to the Myrtaceae family, widely distributed in the Amazon basin, with those of sleeve gastrectomy, on the weight and glycemia of Wistar rats., Methods: twenty-four Wistar rats underwent obesity induction through a hyperlipid diet for eight weeks (fat period), and were randomized into three groups: Control Group (CG), Camu-Camu Group (CCG) and Bariatric Surgery Group (BSG). After this period, all animals returned to a normal diet and the intervention period began: CG did not undergo any intervention beyond diet change; CCG animals underwent gavage procedure for administration of Camu-Camu hydroalcoholic extract, 1g/kg/day, for four weeks; and the BSG was submitted to the surgical procedure of sleeve gastrectomy. We followed all animals for four weeks., Results: there was only one loss in BSG due to a gastric fistula. We observed significant variations in the animals' mean weight: the CG evolved with weight gain even after the withdraw of the hypercaloric diet, while the other two groups presented weight reduction. BSG presented a significant reduction of weight and BMI (p<0.05); CCG achieved a significant reduction only of the BMI (p<0.05). There were no statistically significant changes in the glycemic levels., Conclusion: in spite of reducing weight, the crude hydroalcoholic extract of the Camu-Camu peel was not able to be as efficient as sleeve gastrectomy in the control of body weight in Wistar rats.

Background: Breast cancer diagnosis may be a teachable moment for lifestyle behaviour change and to prevent adjuvant therapy associated weight gain. We assessed the acceptability and effectiveness of two weight control programmes initiated soon after breast cancer diagnosis to reduce weight amongst overweight or obese women and prevent gains in normal-weight women., Methods: Overweight or obese (n = 243) and normal weight (n = 166) women were randomised to a three-month unsupervised home (home), a supervised community weight control programme (community) or to standard written advice (control). Primary end points were change in weight and body fat at 12 months. Secondary end points included change in insulin, cardiovascular risk markers, quality of life and cost-effectiveness of the programmes., Results: Forty-three percent of eligible women were recruited. Both programmes reduced weight and body fat: home vs. control mean (95% CI); weight -2.3 (-3.5, -1.0) kg, body fat -1.6 (-2.6, -0.7) kg, community vs. control; weight -2.4 (-3.6, -1.1) kg, body fat -1.4 (-2.4, -0.5) kg (all p < 0.001). The community group increased physical activity, reduced insulin, cardiovascular disease risk markers, increased QOL and was cost-effective., Conclusions: The programmes were equally effective for weight control, but the community programme had additional benefits., Clinical Trial Registration: ISRCTN68576140.

Background and Aims: Increased body mass index (BMI = weight/height2; kg/m2) and weight gain is associated with increased mortality, wherefore weight loss and avoided weight gain should be followed by lower mortality. This is achieved in clinical settings, but in the general population weight loss appears associated with increased mortality, possibly related to the struggles with body weight control (BWC). We investigated whether attitudes to and experiences with BWC in combination with recent changes in body weight influenced long-term mortality among normal weight and overweight individuals., Population and Methods: The study population included 6,740 individuals attending the 3rd cycle in 1991-94 of the Copenhagen City Heart Study, providing information on BMI, educational level, health behaviours, well-being, weight half-a-year earlier, and answers to four BWC questions about caring for body weight, assumed benefit of weight loss, current and past slimming experiences. Participants reporting previous unintended weight loss (> 4 kg during one year) were excluded. Cox regression models estimated the associations of prior changes in BMI and responses to the BWC questions with approximately 22 years all-cause mortality with age as 'time scale'. Participants with normal weight (BMI < 25.0 kg/m2) and overweight (BMI ≥ 25.0 kg/m2) were analysed separately, and stratified by gender and educational level, health behaviours and well-being as co-variables., Results: Compared with stable weight, weight loss was associated with significantly increased mortality in the normal weight group, but not in the overweight group, and weight gain was not significantly associated with mortality in either group. Participants with normal weight who claimed that it would be good for their health to lose weight or that they were currently trying to lose weight had significantly higher mortality than those denying it. There were no other significant associations with the responses to the BWC questions in either the normal weight or the overweight group. When combining the responses to the BWC questions with the weight changes, using the weight change as either a continuous or categorical variable, there were no significant interaction in their relation to mortality in either the normal weight or the overweight group., Conclusion: Attitudes to and experiences with BWC did not notably modify the association of changes in body weight with mortality in either people with normal weight or people with overweight., Competing Interests: The authors have declared that no competing interests exist.

There is not much evidence about how diet strictness during weekends and holidays influence long-term weight loss maintenance. Our aim was to examine how dieting more or less strictly during weekends and holidays (vs. weekdays and non-holiday periods) influence weight loss maintenance.Participants (n = 108) from the Portuguese Weight Control Registry indicated whether they had a more or less strict diet regimen during weekends compared to weekdays. A similar question about holiday and non-holiday period' diet regimen was answered. Weight and height were measured at baseline and 1y follow-up. A 3% maximum weight variation defined participants as "non-regainers".General level on dieting strictness on weekends vs. weekdays (r = - 0.28, p < 0.01) and holidays vs. non-holidays (r = - 0.33, p < 0.001) predicted 1y weight change.Participants who reported being less strict on weekends (OR = 0.34, 95% CI: 0.15-0.81) were more likely to be non-regainers when compared with the ones who reported being more strict on weekends. Non-significant results were found during holidays (OR = 0.47, 95% CI: 0.20-1.09).Adopting a less strict diet regimen during weekends, when compared to weekdays, was a behavioral strategy associated with long-term weight management in our sample.

Objective: Research has highlighted a growing trend among young, adult women to initiate drug use for weight loss. With known suppressive effects on appetite, illicit stimulants (i.e., cocaine, amphetamine, methamphetamine, and ecstasy) may be particularly attractive to college women, who are at elevated risk for increased body dissatisfaction and experimenting with extreme weight loss techniques. The current study examines the association between risk factors and symptomatology of eating disorders and illicit stimulant use (ISU)., Methods: A preliminary study was conducted on a nonclinical sample of 131 drug-using, college women (16- to 24-years old). Participants reported internalization of the thin ideal, body dissatisfaction, disordered eating behavior, and current drug use as well as corresponding weight-related motivation., Results: There were 15.3% of women who reported drug use for weight-control purposes. Results showed women who reported drug use for weight control predominantly used illicit stimulants (70%), such as cocaine, amphetamine, methamphetamine, and ecstasy. Moreover, the odds of ISU were increased among women who engaged in laxative misuse., Conclusions: These results suggest that a desire for weight control may be associated with ISU among college women. Women engaging in more extreme weight loss behaviors are at high risk for initiating and maintaining ISU for weight-related reasons., (Copyright © 2018. Published by Elsevier Ltd.)

We evaluated the association of social factors and weight control practices in adolescents, and the mediation of this association by weight perception, in a national survey of students in Mexico ( n = 28,266). We employed multinomial and Poisson regression models and Sobel's test to assess mediation. Students whose mothers had a higher level of education were more likely to perceive themselves as overweight and also to engage in weight control practices. After adjusting for body weight perception, the effect of maternal education on weight control practices remained significant. Mediation tests were significant for boys and non-significant for girls.

Objective: Eating behaviors such as dietary restraint and disinhibition caused by emotional and external cues play a relevant role in weight-loss maintenance., Methods: Four hundred forty individuals with successful weight-loss maintenance included in the prospective German Weight Control Registry completed the Dutch Eating Behavior Questionnaire. Participants were categorized into the following two weight groups: stable weight trajectory (WS) (n = 280) and unstable weight trajectory (WUS) (n = 160) over the 2-year assessment period., Results: Those with successful weight-loss maintenance had significantly higher scores on the restrained and emotional eating subscales compared with a general population (GP) sample. At baseline, the WS individuals had lower restrained, emotional, and external eating scores compared with the WUS individuals. Over the 2-year follow-up period, the trajectories of the restraint scores decreased in both groups but stayed elevated compared with the GP sample. Scores of the emotional and external eating subscales remained stable in the WS group but increased in the WUS group., Conclusions: A certain degree of restraint seems to be necessary for successful weight-loss maintenance; however, high emotional and external eating may counteract this effect, resulting in weight regain in the long run., (© 2018 The Obesity Society.)

Unhealthy weight control behaviors (UWCBs) have been decreasing for most youth over time, yet little is known whether these behaviors have changed for sexual minority (e.g., non-heterosexual) youth. This is important because many studies have found that sexual minorities report some of the highest rates of UWCBs. To determine whether or not these behaviors have changed over time, given the extreme changes in social contexts over the past two decades, we utilised three waves of the Minnesota Student Survey (N = 55,597, M age  = 17). In doing so, we report trends, disparities, and changes in disparities of UWCBs. Overall, the prevalence of UWCBs has declined from 1999 to 2010 for all youth, but there are alarming disparities by sex of sexual partner. We found that both- and same-sex partnered male youth were more likely to fast, use diet pills, and vomit on purpose to lose weight compared to their opposite-sex partnered counterparts in all three survey years; specifically, both-sex partnered boys were up to 5.5× as likely to vomit on purpose compared to their opposite-sex partnered counterparts. Likewise, both-sex partnered girls were more likely to use diet pills and vomit on purpose to lose weight compared to opposite-sex partnered girls in all three survey years. Additionally, the disparity in fasting to lose weight widened for the same-sex partnered females compared to the opposite-sex partnered females from 1998 to 2004. This has implications for UWCB interventions and preventions targeted specifically towards sexual minorities.

Objective: Shared behaviors have been implicated in the clustering of obesity among socially connected people. This study determined how weight and weight control behaviors of participants and their social ties are related and how these factors are associated with weight change in participants., Method: Adult Latinas participating in a lifestyle intervention completed an egocentric network measure of weight and weight control behaviors. Participant weight was objectively measured at baseline and 12 months. Multivariable regression models determined the relationship between weight and weight control behaviors of participants and their social ties., Results: Participants and their social ties shared similarities in weight control behaviors and weight change. Participants who reported social ties that had lost weight were more likely to eat small portions and low-fat foods, but those with social ties that had gained weight were more likely to use herbal supplements. Participants who reported more social ties who exercised, drank liquid meal replacements, took herbal supplements, and self-weighed were more likely to lose weight whereas those with fewer social ties that exercised were more likely to gain weight. Weight loss and weight gain by social ties predicted participant weight loss and weight gain, respectively., Conclusions: Given that weight and weight control behaviors of Latinas reflect that of their social ties, targeting existing social networks for lifestyle interventions may more effectively improve and sustain health-promoting behaviors and outcomes.

Objective: To investigate the association between the perception of body weight (as above or below the desired) and behaviors for body weight control in adolescents., Methods: This was a cross-sectional study that included 1051 adolescents (aged 15-19 years) who were high school students attending public schools. The authors collected information on the perception of body weight (dependent variable), weight control behaviors (initiative to change the weight, physical exercise, eating less or cutting calories, fasting for 24h, taking medications, vomiting, or taking laxatives), and measured body weight and height to calculate the body mass index and then classify the weight status. Associations were tested by multinomial logistic regression analysis., Results: Adolescents of both sexes who perceived their body weight as below the expected weight took more initiatives to gain weight, and those who perceived themselves as overweight made more efforts to lose weight. In adolescents who perceived themselves as overweight, the behavior of not taking medication was associated with the outcome only in boys (Odds Ratio=8.12), whereas in girls, an association was observed with the variables eating less, cutting calories, or avoiding fatty foods aiming to lose or avoid increasing body weight (Odds Ratio=3.39). Adolescents of both sexes who practiced exercises were more likely to perceive themselves as overweight (male Odds Ratio=2.00; Odds Ratio=1.93 female)., Conclusion: The perception of the body weight as above and below one's expected weight was associated with weight control behaviors, which were more likely to result in initiatives to lose and gain weight, respectively., (Copyright © 2017 Sociedade Brasileira de Pediatria.

To describe key behaviors reported by participants in the Portuguese Weight Control Registry and to determine associations between these behaviors and weight loss maintenance. A total of 388 adults participated in this cross-sectional study. Assessments included demographic information, weight history, weight loss and weight maintenance strategies, dietary intake, and physical activity. Participants lost on average 18 kg, which they had maintained for ~28 months. Their average dietary intake was 2199 kcal/day, with 33 % of energy coming from fat. About 78 % of participants engaged in levels of moderate-plus-vigorous physical activity exceeding 150 min/week (51 % above 250 min/week), with men accumulating 82 more minutes than women (p < 0.05). The most frequently reported strategies for both weight loss and maintenance were keeping healthy foods at home, consuming vegetables regularly, and having daily breakfast. Greater weight loss maintenance was associated with higher levels of physical activity, walking, weight self-monitoring, establishing specific goals, and with reduced portion size use, reduced consumption of carbohydrates, and increased consumption of protein, (p < 0.05). Results indicate that weight loss maintenance is possible through the adoption of a nutritionally-balanced diet and regular participation in physical activity, but also suggest that adopting different (and, to a degree, individualized) set of behavioral strategies is key for achieving success.

Introduction: The present study examined predictors of negative changes in weight control intentions from before to during the COVID‐19 pandemic among adolescents. Methods: Participants were Canadian secondary school students enrolled in the COMPASS study and had completed self‐report surveys before (T1; 2018/2019 and/or 2019/2020 school year) and during (T2; 2020/2021 and/or 2021/2022) the COVID‐19 pandemic (N = 11,869, Mage ± SD = 13.79 years old ± 1.15, 52.89% girls, 45.30% boys, 1.81% gender diverse). Demographic, interpersonal, behavioral, and psychological predictors of weight control intention change from T1 (stay the same weight, not doing anything about weight) to T2 (lose weight, gain weight) were tested using multilevel logistic regressions. Results: Over one‐third (37.0%) of adolescents who reported wanting to stay the same weight at T1 changed their intention to lose or gain weight at T2, as did 28.5% of adolescents who reported not wanting to do anything about their weight at T1. Changing weight control intention from "not doing anything about weight" at T1 to weight gain/loss at T2 was associated with resistance training, emotion dysregulation, bullying, social media use, and gender. Changing weight control intention from "stay the same weight" at T1 to weight gain/loss at T2 was associated with gender, perceived financial comfort, social media use, and flourishing. Conclusions: Results highlight the prevalence of maladaptive weight control intention changes among adolescents, and elucidate related behavioral, interpersonal, demographic, and psychological factors. Findings can inform targeted intervention and prevention strategies to disrupt maladaptive changes in weight control intentions among high‐risk subgroups. [ABSTRACT FROM AUTHOR]
