Protocol for a prospective, randomized, controlled trial of Mental Contrasting with Implementation Intentions (MCII) to enhance the effectiveness of VA's MOVE! weight management program: WOOP (Wish, Outcome, Obstacle, Plan) VA.

INTRODUCTION: Intensive weight management programs are effective but often have low enrollment and high attrition. Lack of motivation is a key psychological barrier to enrollment, engagement, and weight loss. Mental Contrasting with Implementation Intentions (MCII) is a unique imagery technique that increases motivation for behavior change. We describe our study protocol to assess the efficacy and implementation of MCII to enhance the effectiveness of VA's MOVE! or TeleMOVE! weight management programs using a procedure called "WOOP" (Wish, Outcome, Obstacle, Plan) for Veterans. We hypothesize that WOOP+MOVE! or TeleMOVE! (intervention) will lead to greater MOVE!/TeleMOVE! program engagment and consequently weight loss than MOVE!/TeleMOVE! alone (control). METHOD: Veterans are randomized to either the intervention or control. Both arms receive the either MOVE! or TeleMOVE! weight management programs. The intervention group receives an hour long WOOP training while the control group receives patient education. Both groups receive telephone follow up calls at 3 days, 4 weeks, and 2 months post-baseline. Eligible participants are Veterans (ages 18-70 years) with either obesity (BMI ≥ 30 kg/m2) or overweight (BMI ≥ 25 kg/m2) and an obesity-associated co-morbidity. At baseline, 6 and 12 months, we assess weight, diet, physical activity in both groups. The primary outcome is mean percent weight change at 6 months. Secondary outcomes include changes in waist circumference, diet, physical activity, and dieting self-efficacy and engagement in regular physical activity. We assess implementation using the RE-AIM framework. CONCLUSION: If WOOP VA is found to be efficacious, it will be an important tool to facilitate weight management and improve weight outcomes.

Interventions to prevent or manage obesity in Maori and Pacific adults: a systematic review and narrative synthesis.

OBJECTIVES: Obesity and its sequelae are an increasing problem, disproportionally affecting Maori and Pacific peoples, secondary to multifactorial systemic causes, including the effects of colonisation and the impact of globalisation. There is limited synthesised evidence on interventions to address obesity in these populations. The objective of this review is to identify evaluated interventions for prevention and management of obesity amongst Maori and Pacific adults, assess the effectiveness of these interventions, and identify enablers and barriers to their uptake. DESIGN: Systematic review of databases (Medline, PubMed, EMBASE, CINAHL, Scopus, CENTRAL), key non-indexed journals, and reference lists of included articles were searched from inception to June 2021. Eligibility criteria defined using a Population, Intervention, Control, Outcome format and study/publication characteristics. Quantitative and qualitative data were extracted and analysed using narrative syntheses. Study quality was assessed using modified GRADE approach. RESULTS: From the 8190 articles identified, 21 were included, with 18 eligible for quantitative and five for qualitative analysis. The studies were heterogenous, with most graded as low quality. Some studies reported small but statistically significant improvements in weight and body mass index. Key enablers identified were social connection, making achievable sustainable lifestyle changes, culturally-centred interventions and incentives including money and enjoyment. Barriers to intervention uptake included difficulty in maintaining adherence to a programme due to intrinsic programme factors such as lack of social support and malfunctioning or lost equipment. CONCLUSIONS: Normal weight trajectory is progressive increase over time. Modest weight loss or no weight gain after several years may have a positive outcome in lowering progression to diabetes, or improvement of glycaemic control in people with diabetes. We recommend urgent implementation of Maori and Pacific-led, culturally-tailored weight loss programmes that promote holistic, small and sustainable lifestyle changes delivered in socially appropriate contexts.

"I Want a Program That Looks at My Whole Life." A Focus Group Study on the Ideal Components for an mHealth Weight Management Program for African American Women.

BACKGROUND: The high rate of obesity, ownership of smartphones, and online search for nutrition and dieting information among African American women (AAW) provide a unique opportunity to develop cost-effective, accessible, and acceptable mHealth weight management programs for them. Furthermore, they should participate in the development and evaluation of these programs. OBJECTIVE: To explore ideal components of a culturally relevant mHealth weight management program for AAW and to examine how these components may vary by age group. DESIGN: Twelve focus group triads were conducted with AAW in north central Florida. The framework method was used to manage, organize, synthesize, and analyze data themes by age groups: 18 to 29 (young), 30 to 50 (middle age), and 51+ (older). PARTICIPANTS/SETTING: Thirty-six smartphone owners who expressed a desire to lose weight were recruited through several community partnerships. RESULTS: Based on body mass index (BMI), young women were classified as overweight (BMI 26.23 ± 6.7), middle-aged women as obese (BMI30.72 ± 8.31), and older women as obese (BMI 31.03 ± 5.67). Most searched online for dieting information within the past 12 months. Five overarching themes for designing mHealth weight management programs were identified: (1) holistic program that goes beyond dieting; (2) social media integration for support and sense of community; (3) self-monitoring app; (4) two-way text messaging; and (5) programs of varying lengths and meaningful incentives. CONCLUSION: AAW were receptive to mHealth weight management programs, which may be appealing during and after the COVID-19 pandemic. Holistic programs of 4 to 6 weeks that addressed stress eating, had a social media component, and included a few educational texts per week may be appealing to AAW.

Branched Chain Amino Acid Supplementation to a Hypocaloric Diet Does Not Affect Resting Metabolic Rate but Increases Postprandial Fat Oxidation Response in Overweight and Obese Adults after Weight Loss Intervention.

BACKGROUND: Branched chain amino acids (BCAA) supplementation is reported to aid in lean mass preservation, which may in turn minimize the reduction in resting metabolic rate (RMR) during weight loss. Our study aimed to examine the effect of BCAA supplementation to a hypocaloric diet on RMR and substrate utilization during a weight loss intervention. METHODS: A total of 111 Chinese subjects comprising 55 males and 56 females aged 21 to 45 years old with BMI between 25 and 36 kg/m2 were randomized into three hypocaloric diet groups: (1) standard-protein (14%) with placebo (CT), (2) standard-protein with BCAA, and (3) high-protein (27%) with placebo. Indirect calorimetry was used to measure RMR, carbohydrate, and fat oxidation before and after 16 weeks of dietary intervention. RESULTS: RMR was reduced from 1600 ± 270 kcal/day to 1500 ± 264 kcal/day (p < 0.0005) after weight loss, but no significant differences in the change of RMR, respiratory quotient, and percentage of fat and carbohydrate oxidation were observed among the three diet groups. Subjects with BCAA supplementation had an increased postprandial fat (p = 0.021) and decreased postprandial carbohydrate (p = 0.044) oxidation responses compared to the CT group after dietary intervention. CONCLUSIONS: BCAA-supplemented standard-protein diet did not significantly attenuate reduction of RMR compared to standard-protein and high-protein diets. However, the postprandial fat oxidation response increased after BCAA-supplemented weight loss intervention.

Obesity and Eating Disorders in Children and Adolescents: The Bidirectional Link.

Obesity, eating disorders and unhealthy dieting practices among children and adolescents are alarming health concerns due to their high prevalence and adverse effects on physical and psychosocial health. We present the evidence that eating disorders and obesity can be managed or prevented using the same interventions in the pediatric age. In the presence of obesity in the pediatric age, disordered eating behaviors are highly prevalent, increasing the risk of developing eating disorders. The most frequently observed in subjects with obesity are bulimia nervosa and binge-eating disorders, both of which are characterized by abnormal eating or weight-control behaviors. Various are the mechanisms overlying the interaction including environmental and individual ones, and different are the approaches to reduce the consequences. Evidence-based treatments for obesity and eating disorders in childhood include as first line approaches weight loss with nutritional management and lifestyle modification via behavioral psychotherapy, as well as treatment of psychiatric comorbidities if those are not a consequence of the eating disorder. Drugs and bariatric surgery need to be used in extreme cases. Future research is necessary for early detection of risk factors for prevention, more precise elucidation of the mechanisms that underpin these problems and, finally, in the cases requiring therapeutic intervention, to provide tailored and timely treatment. Collective efforts between the fields are crucial for reducing the factors of health disparity and improving public health.

A Natural Experiment Comparing the Effectiveness of the "Healthy Eagles" Child Weight Management Intervention in School Versus Community Settings.

Behavioural weight management interventions are recommended for the treatment of obesity in children. However, the evidence for these is limited and often generated under trial conditions with White, middle-class populations. Healthy Eagles is a behavioural weight management intervention designed to treat excess weight in children. It ran in the London Borough of Croydon from 2017 to 2020 and was delivered in both school and community settings, providing a natural experiment to compare outcomes. A total of 1560 participants started the Healthy Eagles programme; 347 were in the community setting and 703 in the school setting. Data were analysed for those who completed 70% of the programme. In the school setting, there was a small but significant reduction in BMI z-score (M = -0.04, 95% CI = -0.08, -0.01) for participants above a healthy weight, especially in those with severe obesity (M = -0.09, 95% CI = -0.15, -0.03); there was no significant change in any subgroup in the community setting. Linear regression analysis showed the school setting was associated with a 0.26 (95% CI = 0.13, 0.49) greater reduction in BMI z-score than the community setting after adjusting for ethnicity, deprivation, age and gender. Across both programmes, the effect was somewhat greater in participants from a Black (African/Caribbean/Other) ethnic background (M = -0.06, 95% CI = -0.09, -0.02) and from the two most deprived quintiles (M = -0.06, 95% CI = -0.11, -0.01). Data were limited, but minimal changes were measured in nutrition and physical activity behaviours regardless of setting. This evaluation provides indirect evidence of a small but significant benefit to running weight management interventions in a school versus community setting.

Rationale and Methods for a Randomized Controlled Trial of a Dyadic, Web-Based, Weight Loss Intervention among Cancer Survivors and Partners: The DUET Study.

Scalable, effective interventions are needed to address poor diet, insufficient physical activity, and obesity amongst rising numbers of cancer survivors. Interventions targeting survivors and their friends and family may promote both tertiary and primary prevention. The design, rationale, and enrollment of an ongoing randomized controlled trial (RCT) (NCT04132219) to test a web-based lifestyle intervention for cancer survivors and their supportive partners are described, along with the characteristics of the sample recruited. This two-arm, single-blinded RCT randomly assigns 56 dyads (cancer survivor and partner, both with obesity, poor diets, and physical inactivity) to the six-month DUET intervention vs. wait-list control. Intervention delivery and assessment are remotely performed with 0-6 month, between-arm tests comparing body weight status (primary outcome), and secondary outcomes (waist circumference, health indices, and biomarkers of glucose homeostasis, lipid regulation and inflammation). Despite COVID-19, targeted accrual was achieved within 9 months. Not having Internet access was a rare exclusion (<2%). Inability to identify a support partner precluded enrollment of 42% of interested/eligible survivors. The enrolled sample is diverse: ages 23-81 and 38% racial/ethnic minorities. Results support the accessibility and appeal of web-based lifestyle interventions for cancer survivors, though some cancer survivors struggled to enlist support partners and may require alternative strategies.

Change in Blood and Benign Breast Biomarkers in Women Undergoing a Weight-Loss Intervention Randomized to High-Dose ω-3 Fatty Acids versus Placebo.

The inflammation-resolving and insulin-sensitizing properties of eicosapentaenoic (EPA) and docosahexaenoic (DHA) fatty acids have potential to augment effects of weight loss on breast cancer risk. In a feasibility study, 46 peri/postmenopausal women at increased risk for breast cancer with a body mass index (BMI) of 28 kg/m2 or greater were randomized to 3.25 g/day combined EPA and DHA (ω-3-FA) or placebo concomitantly with initiation of a weight-loss intervention. Forty-five women started the intervention. Study discontinuation for women randomized to ω-3-FA and initiating the weight-loss intervention was 9% at 6 months and thus satisfied our main endpoint, which was feasibility. Between baseline and 6 months significant change (P < 0.05) was observed in 12 of 25 serum metabolic markers associated with breast cancer risk for women randomized to ω-3-FA, but only four for those randomized to placebo. Weight loss (median of 10% for trial initiators and 12% for the 42 completing 6 months) had a significant impact on biomarker modulation. Median loss was similar for placebo (-11%) and ω-3-FA (-13%). No significant change between ω-3-FA and placebo was observed for individual biomarkers, likely due to sample size and effect of weight loss. Women randomized to ω-3-FA exhibiting more than 10% weight loss at 6 months showed greatest biomarker improvement including 6- and 12-month serum adiponectin, insulin, omentin, and C-reactive protein (CRP), and 12-month tissue adiponectin. Given the importance of a favorable adipokine profile in countering the prooncogenic effects of obesity, further evaluation of high-dose ω-3-FA during a weight-loss intervention in obese high-risk women should be considered. PREVENTION RELEVANCE: This study examines biomarkers of response that may be modulated by omega-3 fatty acids when combined with a weight-loss intervention. While focused on obese, postmenopausal women at high risk for development of breast cancer, the findings are applicable to other cancers studied in clinical prevention trials.

Management of Childhood Obesity-Time to Shift from Generalized to Personalized Intervention Strategies.

As a major public health concern, childhood obesity is a multifaceted and multilevel metabolic disorder influenced by genetic and behavioral aspects. While genetic risk factors contribute to and interact with the onset and development of excess body weight, available evidence indicates that several modifiable obesogenic behaviors play a crucial role in the etiology of childhood obesity. Although a variety of systematic reviews and meta-analyses have reported the effectiveness of several interventions in community-based, school-based, and home-based programs regarding childhood obesity, the prevalence of children with excess body weight remains high. Additionally, researchers and pediatric clinicians are often encountering several challenges and the characteristics of an optimal weight management strategy remain controversial. Strategies involving a combination of physical activity, nutritional, and educational interventions are likely to yield better outcomes compared to single-component strategies but various prohibitory limitations have been reported in practice. This review seeks to (i) provide a brief overview of the current preventative and therapeutic approaches towards childhood obesity, (ii) discuss the complexity and limitations of research in the childhood obesity area, and (iii) suggest an Etiology-Based Personalized Intervention Strategy Targeting Childhood Obesity (EPISTCO). This purposeful approach includes prioritized nutritional, educational, behavioral, and physical activity intervention strategies directly based on the etiology of obesity and interpretation of individual characteristics.

Commercial Weight Loss Programs in the Management of Obesity: an Update.

PURPOSE OF REVIEW: Comprehensive lifestyle programs are cornerstones of obesity management, but clinician referrals may be limited by program availability. Commercial weight loss programs may be an alternative, but clinicians may be unaware of their efficacy and safety. This review describes the evidence for commercial programs, particularly 12-month weight loss, among individuals with obesity. RECENT FINDINGS: Several programs are concordant with evidence-based recommendations (i.e., lower-calorie diet, increased physical activity, and behavioral strategies). Among the guideline-concordant programs, National Diabetes Prevention Program, WW, Jenny Craig, Medifast, and OPTIFAST have demonstrated 12-month weight loss efficacy and safety. While other programs show promise, more evidence is needed before clinician referral may be recommended. Clinical practice guidelines support referrals to commercial weight loss programs that have peer-reviewed evidence to support their efficacy and safety. Clinicians should consider the available evidence, patient preference, and cost when considering referrals to these programs for weight management.

Feasibility of Integration of Yoga in a Behavioral Weight-Loss Intervention: A Randomized Trial.

OBJECTIVE: This study examined the feasibility and comparison of two styles of yoga within the context of a standard behavioral weight-loss intervention (SBWI). METHODS: Fifty adults with obesity (BMI: 31.3 ± 3.8 kg/m2 ) participated in this 6-month study that included a SBWI and a calorie- and fat-reduced diet. Randomization was to restorative Hatha (SBWI+RES) or Vinyasa (SBWI+VIN) yoga. Yoga was prescribed to increase from 20 to 40 to 60 minutes per session across the intervention. Weight was assessed at baseline and 6 months. Perceptions of yoga were assessed at the completion of the intervention. RESULTS: Adjusted weight loss was -3.4 kg (95% CI: -6.4 to -0.5) in SBWI+RES and -3.8 kg (95% CI: -6.8 to -0.9) in SBWI+VIN (P < 0.001), with no difference between groups. Of all participants, 74.4% reported that they would continue participation in yoga after the SBWI. Session duration was a barrier as yoga increased from 20 to 40 to 60 minutes per day, with 0%, 7.5%, and 48.8% reporting this barrier, respectively. CONCLUSIONS: Among adults with obesity, yoga participation, within the context of a SBWI, appears to be feasible, with weight loss not differing by style of yoga. Progressing to 60 minutes per session appears to be a barrier to engagement in yoga in this population.

Patients Desire Personalized, Specific, and Continuous Advice on Weight Management.

OBJECTIVE: To deliver effective care, healthcare systems should understand patients' preferences for weight management across a spectrum of needs. Our objective was to describe patients' perceptions of what helps or hinders weight loss and maintenance. METHODS: Semistructured interviews were conducted with patients who accessed weight management services at a large integrated health system in 2018. The interview guide was developed and iteratively refined through a literature search and by consulting experts. Questions included the respondent's weight history, interactions with the health system, and current health status. The analysis used a grounded theory approach, and each transcript was double-coded in 2019. Codes were sorted into themes. All discrepancies were resolved through team discussion. RESULTS: Fifteen patients were interviewed. The majority of respondents (87%) reported multiple weight loss attempts. Three themes were identified. First, advice should be matched to a patient's knowledge and prior experience (eg, using bariatric deck cards). As patients progressed, clinician advice also needed to advance (eg, explaining how to expand food options instead of defining a healthy diet). Second, respondents had a variety of motivating factors, and understanding where motivation is generated from can inform how to design a weight management approach. Third, patients need continual and long-term advice. Some respondents feared becoming ineligible for services if their weight dropped too much. CONCLUSIONS: Health systems can support patients by developing processes for identifying the extent of a patient's knowledge and giving personalized advice based on the patient's preferences and experiences. Reassessing needs at defined intervals may help patients attain and sustain their goals.

Episodic future thinking, delay discounting, and exercise during weight loss maintenance: The PACE trial.

OBJECTIVES: Weight loss maintenance (WLM) is the next major challenge in obesity treatment. While most individuals who lose weight intend to keep their weight off, weight regain is common. Temporal Self-Regulation Theory posits that whether intentions lead to behavior depends on self-regulatory capacity, including delay discounting (DD; the tendency to discount a larger future reward in favor of a smaller immediate reward). Episodic Future Thinking (EFT; mental imagery of a future event for which a health goal is important) may improve DD and promote behavior change. Described herein is a trial protocol designed to examine whether EFT improves DD within the context of weight loss maintenance. METHOD: Participants who lose ≥5% of initial body weight in an online behavioral weight loss intervention will be randomly assigned to a standard weight loss maintenance program (WLM-STD) or a weight loss maintenance program plus EFT (WLM + EFT). Both interventions involve periodic phone and in-person treatment sessions. Participants in WLM + EFT will engage in daily EFT training via smartphone. To control for contact, participants in WLM-STD will engage in daily Healthy Thinking (reviewing strategies for weight management) on their smartphone. Our primary hypothesis is that WLM + EFT will yield better improvements in DD compared to WLM-STD. We will also explore whether DD mediates the relationship between intervention allocation and physical activity (secondary outcome). Weight and contextual variables will be explored. CONCLUSIONS: This study is the first to test whether EFT improves DD within the context of weight loss maintenance; results from this experimental medicine approach could have important implications for understanding the impact of both EFT and DD on sustained behavior change.

Regular Consumption of Lipigo® Promotes the Reduction of Body Weight and Improves the Rebound Effect of Obese People Undergo a Comprehensive Weight Loss Program.

Obesity is a global public health problem. OBJECTIVE: To evaluate the effect of the regular consumption of the product Lipigo® on body weight and rebound effect on overweight/obese subjects undergoing a comprehensive weight loss program. METHODS: A randomized, parallel, double-blind, placebo-controlled clinical trial was conducted with male and female subjects presenting a BMI 25-39.9 kg/m2. All subjects underwent a comprehensive weight loss program (WLP) for 12 weeks, which included an individualized hypocaloric diet, physical activity recommendations, nutritional education seminars, and three times a day consumption of the product Lipigo® or Placebo. After-WLP, subjects continued the treatment for 9 months to assess rebound effect. Body weight (BW), BMI, and body composition were measured at the beginning and the end of the WLP, and in the follow-up. RESULTS: A total of 120 subjects (85% women) 49.0 ± 9.5 years old and with a BW of 81.57 ± 13.26 kg (BMI 31.19 ± 3.44 kg/m2) were randomized and 73 subjects finished the study. At the end of the WLP, there was a tendency toward reduced BW (p = 0.093), BMI (p = 0.063), and WC (p = 0.059) in the treated group. However, subjects with obesity type 1 (OB1) from the treated group significantly reduced body weight (-5.27 ± 2.75 vs. -3.08 ± 1.73 kg; p = 0.017) and BMI (-1.99 ± 1.08 vs. -1.09 ± 0.55 kg/m2; p = 0.01) compared with placebo. They also presented a minor rebound effect after 9 months with product consumption (-4.19 ± 3.61 vs. -1.44 ± 2.51 kg; p = 0.026), minor BMI (-1.61 ± 1.43 vs. -0.52 ± 0.96 kg/m2; p = 0.025) and tended to have less fat-mass (-3.44 ± 2.46 vs. -1.44 ± 3.29 kg; p = 0.080) compared with placebo. CONCLUSIONS: The regular consumption of the product Lipigo® promotes the reduction of body weight and reduces the rebound effect of obese people after 52 weeks (12 months), mainly in obesity type 1, who undergo a comprehensive weight loss program.

Designing and validation of a yoga-based module for obesity with metabolic comorbidities.

OBJECTIVES: Obesity is a condition of increased adipose tissue in the body, which is commonly associated with various comorbidities like diabetes, hypertension, arthritis, back pain, and many others. Yoga modules have been designed and validated for obesity; however, we couldn't find any specific module for metabolic syndrome, a condition which includes obesity, diabetes mellitus type 2 and/or hypertension together. Keeping this in view, our study aimed to develop and validate a specific generic yoga-based intervention module for metabolic syndrome patients. MATERIALS AND METHODS: A yoga module was designed based on traditional and contemporary yoga literature as well as published studies. We derived the yoga practices for the module, from these yoga texts and research evidence were already available. The yoga module was sent to 40 yoga experts for their validation. RESULTS: Twenty-two experts gave their opinion on the usefulness of a yoga module for patients with metabolic syndrome with some suggestions. Of these experts, 73% were males, and 27% were females. Yoga therapy practices with content validity ratio (CVR) >0.08 were included in the final module. In total, 86% (31 of 36 items) of the items in the initial module were retained. CONCLUSION: A specific yoga-based module for metabolic syndrome was designed and validated by experts. Further studies are needed to confirm the efficacy and clinical utility of the module.Additional clinical validation is suggested.

Effects of Pistachio Consumption in a Behavioral Weight Loss Intervention on Weight Change, Cardiometabolic Factors, and Dietary Intake.

Epidemiological studies have linked regular nut consumption with lower body mass index and reduced likelihood of weight gain in adulthood. Nuts can displace other foods in the diet, and thus, promote a healthier dietary pattern. The purpose of this study was to examine the effect of pistachio nut consumption in overweight/obese adults. This randomized controlled study enrolled non-diabetic overweight/obese adults (n = 100) assigned to a 4-month behavioral weight loss intervention only group (controls) or also prescribed 1.5 oz/day (42 g/day) of pistachios (pistachio group). Outcomes were change in body weight, cardiometabolic factors, and dietary intake. Percent weight change was similar in the two groups (-5.1 [0.5] (mean [SE])% in the control group and -4.9 [0.6]% in the pistachio group, and body mass index (BMI) and waist circumference were reduced in both groups (time effect p ≤ 0.05). The pistachio group (but not the control group) exhibited a significant reduction in both systolic and diastolic blood pressure (time effect p = 0.01). Plasma alpha-carotene, beta-carotene, and lutein concentrations increased significantly in the pistachio group (time effect p < 0.05). Pistachio consumption was associated with increased dietary fiber intake and decreased consumption of sweets. Regular consumption of pistachios was associated with a comparable degree of weight loss, and similar reductions in BMI and waist circumference, in overweight/obese men and women compared to controls, and favorable changes in the diet, in the context of a behavioral weight loss intervention.

Effects of Rapid Weight Loss on Judo Athletes: A Systematic Review.

Rapid weight loss (RWL) is commonly practiced among judo athletes. Although it helps them to gain the advantage over their lighter opponents, previous studies have shown that RWL can have a negative impact on the athlete's performance and overall well-being. This systematic review aimed to synthesize the evidence that examines the influence of rapid weight loss on physiological parameters, biomarkers, and psychological well-being in judo athletes. We followed the preferred reporting items for systematic reviews and meta-analyses guidelines. We searched for studies on Web of Science and PubMed that elaborate on the influence of ≥5% RWL achieved over ≤7-day period in judokas. Out of 52 studies initially found, 14 studies met our eligibility criteria and were included in the review. In total, we examined data from 1103 judo athletes. Retrieved studies showed conflicting data concerning physiological parameters and biomarkers, while psychological well-being parameters were more consistent than physiological and biomarkers. The feeling of tension, anger, and fatigue significantly increased while a decrease in vigor was demonstrated among athletes who lost weight rapidly. The evidence on the impact of RWL on performance remains ambiguous. More studies under standardized conditions are needed in order to provide firm evidence. Considering the harmful effects of RWL outlined in the existing literature, it is important to determine and monitor athlete's minimal competitive weight to prioritize the health and safety of the athlete, emphasize fairness, and ultimately benefit the sport.

Mindful Eating and Active Living: Development and Implementation of a Multidisciplinary Pediatric Weight Management Intervention.

Pediatric overweight and obesity are significant individual and public health issues that require an innovative approach. While evidence suggests that intensive family-based behavioral lifestyle modification can improve weight status, practical and logistical realities limit the ability of primary healthcare providers to intervene effectively. MEALs (Multidisciplinary Engagement and Learning/Mindful Eating and Active Living) is a family-based mindfulness intervention developed to address pediatric overweight and obesity, while improving healthy lifestyle behaviors through cooking classes. The incorporation of mindfulness, a psychological strategy associated with increased awareness of internal experiences, allows for a focus on the importance of healthy eating along with safe and efficacious kitchen practices. The Template for Intervention Description and Replication (TIDieR) checklist and guide is used to describe the intervention with the intention of providing necessary details to implement the intervention in clinical practice or replicate the intervention for further study. Lessons learned from pilot iterations of the intervention are provided.

Feasibility and efficacy of a weight gain prevention intervention for breast cancer patients receiving neoadjuvant chemotherapy: a randomized controlled pilot study.

PURPOSE: Weight gain is common among breast cancer patients and may contribute to poorer treatment outcomes. Most programs target breast cancer survivors after the completion of therapy and focus on weight reduction. This study examined the feasibility and preliminary efficacy of an intervention designed to prevent primary weight gain among women receiving neoadjuvant chemotherapy for breast cancer. METHODS: Thirty-eight newly diagnosed stage II or III breast cancer patients were randomized to the BALANCE intervention or usual care within 3 weeks of starting neoadjuvant chemotherapy. The intervention used a size acceptance-based approach and encouraged home-based resistance and moderate-intensity aerobic exercise as well as a low energy-dense diet to prevent weight gain. Assessments were conducted at baseline, mid-chemotherapy (3 months), and post-chemotherapy (6 months). Intervention feasibility, acceptability, and preliminary effects on anthropometric, quality of life, and circulating biomarker measures were evaluated. RESULTS: Intervention participant retention (100%) and in-person session attendance (80%) were high during the intervention period, although attendance dropped to 43% for telephone-delivered sessions. The majority of participants reported being satisfied with the intervention during chemotherapy (88%). Participants in the intervention group had greater reductions in waist circumference (p = .03) and greater improvements in self-reported vitality scores (p = .03) than the control group at the end of chemotherapy. Significant effects on biomarkers were not observed. CONCLUSIONS: A size acceptance weight management program is feasible during neoadjuvant chemotherapy among breast cancer patients and may have beneficial effects on waist circumference and patient vitality. TRIAL REGISTRATION: This study was registered as a clinical trial at www.clinicaltrials.gov (NCT00533338).

Do stress eating or compulsive eating influence metabolic health in a mindfulness-based weight loss intervention?

OBJECTIVE: We aimed to understand the associations of compulsive eating (CE) and stress eating (SE) with metabolic health among adults with obesity and whether mindfulness-based weight loss training may buffer these associations. METHOD: We used data from a trial in which we randomized 194 participants with obesity to a diet-exercise weight loss intervention with either mindful eating training plus mindfulness-based eating awareness and stress management training (n = 100) or active control components (n = 94). We measured CE, SE, weight, and fasting blood glucose (FBG) at baseline, and 6, 12 months, and 18 months. We tested CE and SE as both moderators and mediators of intervention effects on changes in metabolic health. RESULTS: Participants higher (+ 1 SD) in CE at baseline randomized to the mindfulness (vs. control) intervention had greater improvements in FBG at 18 months (p = .05). Twelve-month reductions in CE mediated the effect of the intervention on changes in FBG and weight at 12 and 18 months postbaseline (p ≤ .05). Furthermore, those higher (+ 1 SD) in SE at baseline were nearly 2 BMI points higher than those lower (-1 SD) in SE (p < .01). Decreases in SE (B = 3.42; p < .001; 95% CI [2.55, 4.30]) and CE (B = 0.45; p < .001; 95% CI [0.36, 0.54]) in all participants at 6 months were associated with greater weight loss at 18 months. CONCLUSIONS: Those with greater compulsive eating may reduce risk for metabolic decline by participating in a mindfulness-based weight loss program. Future obesity interventions should consider tailoring treatment toward trait-level characteristics, such as compulsive eating. (PsycINFO Database Record (c) 2020 APA, all rights reserved).
