Abstract
Purpose We aimed to verify the prevalence of dietary supplements among CrossFit practitioners (CFPs), considering gender and training status. Still, we aimed to determine the type, reasons, and associated factors of dietary supplement utilization among CFPs. Methods This is a cross-sectional, exploratory, and descriptive study with the snowball sampling method. Data were collected through online questionnaires using the Google Forms® tool. We included CFPs aged 18-64 years, from Aug 1, 2020, to Sept 31, 2020. The questionnaire contained questions to assess the prevalence, type, and reasons for supplement use; also, we assessed information about sociodemographic variables and the prevalence of the main chronic morbidities. To analyze aspects of eating behavior and sleep-related parameters, we applied the three-factor eating questionnaire (TFEQ)-R21 and the Pittsburgh Sleep Quality Index questionnaire (PSQI), respectively. Results We assessed one hundred twelve (n = 112; 57 men; 55 women) CFPs (28.9 ± 7.64 years old; body mass index (BMI), 25.5 ± 4.83 kg/m2). Eighty-seven (50 men; 37 women; 28.2 ± 6.66 years old; BMI, 25.4 ± 4.55 kg/m2) reported using dietary supplements. Whey protein was the most used supplement (n = 70), followed by creatine (n = 54). Cognitive restraint (a dimension of eating behavior) score was higher in supplement users than in non-users (51.7 ± 18.6 vs. 42.6 ± 20.5; p = 0.040). Sleep-related parameters did not differ between supplement users and non-users. The most associated factors to supplement use were sex (being man; OR, 7.99; p = 0.007), sleep quality (poor; OR, 5.27; p = 0.045), CrossFit level (as prescribed (RX); OR, 4.51; p = 0.031), and cognitive restraint (OR, 1.03; p = 0.029). Conclusion The CFPs, especially RX and Elite ones, showed a higher prevalence of supplement utilization. Anabolic-related supplements (i.e., whey protein and creatine) were the most used; moreover, several CFPs used supplements not supported by scientific evidence. Cognitive restraint score was higher in supplement users than in non-users. RX level, being men, and poor sleep quality were associated with supplement utilization. These data draw attention to the necessity of nutritional education for CrossFit coaches and athletes. Broader studies are necessary to confirm our findings.

Abstract
Eating disorders (EDs) represent a contradictory chapter of clinical psychiatry, i.e., although they are associated with significant prevalence and risks in the long term (including vital risk, especially for anorexia nervosa), the therapeutic resources are minimal and based on low-quality data. Another contradiction arose in the last few decades, i.e., a variety of new EDs have been described, either by clinicians or signaled by mass media, but their systematic exploration is progressing very slowly. Entities like "food addiction," "orthorexia nervosa," or "emotional eating disorder" still require intensive exploration in order to find the most accurate diagnostic instruments, diagnosis criteria, prevalence data, vulnerability factors, and therapeutic approaches. This article is focused on integrating into a comprehensive model a variety of EDs not specified or loosely defined by the current international classifications of psychiatric disorders. This framework is intended as an instrument for stimulating clinical and epidemiological research, with potential favorable consequences for therapeutic research. The dimensional model suggested here includes four main categories that accommodate the already recognized EDs (i.e., anorexia nervosa, bulimia nervosa, and binge eating disorder) as well as ten EDs that still need intensive research to find their clinical and pathophysiological characteristics. More good-quality studies are urgently required regarding this topic, based on the mental and physical negative impact these EDs may have in the short and long term, especially in vulnerable populations (e.g., pregnant women, athletes, adolescents, etc.).

Associations of physical activity and sedentary behavior with appetite sensations and eating regulation behaviors before and during the initial year following bariatric surgery. Obes Sci Pract 2022; 8:164-175.

Abstract
Background Bariatric surgery produces weight loss in part by impacting appetite and eating behavior. Research suggests physical activity (PA) assists with regulation of appetite and eating during non-surgical weight loss, although whether PA carries similar benefits in the context of bariatric surgery is unknown. Objective Evaluate associations of moderate-to-vigorous intensity PA (MVPA) and sedentary time (ST) with appetite sensations (hunger [homeostatic/hedonic], satiety) and eating regulation behaviors (restraint, disinhibition) before and during the initial year following bariatric surgery. Method Adult bariatric patients received an accelerometer to measure MVPA/ST and a smartphone to complete appetite/eating ratings at four semi-random times daily for 10 days at pre- and 3-, 6-, and 12-months post-surgery. Data were analyzed using generalized linear mixed models. Results Higher MVPA levels related to more satiety across time (p = 0.045) and more restraint at 3-months post-surgery (p < 0.001). At pre-surgery, higher MVPA levels also related to more disinhibition (p's < 0.01), although participants reported more disinhibition on days they performed less MVPA than usual (p = 0.017). MVPA did not relate to hunger. Lower ST levels related to more hedonic hunger (p = 0.003), especially at 12-months post-surgery (p < 0.001), and participants reported more homeostatic hunger on days they accumulated more ST than usual (p = 0.044). Additionally, higher ST levels related to more disinhibition at 3-months post-surgery (p's < 0.01) and lower restraint at pre-surgery (p's < 0.05). ST did not relate to satiety. Conclusions This study is the first to show that MVPA and ST each associate with appetite and eating regulation in daily life before and during post-surgical weight loss. Results, while preliminary and requiring experimental confirmation, highlight potential for targeting bariatric patients' activity behaviors to enhance modulation of appetite, control of food intake, and resistance to overeating.

Dietary Habits and Psychological States during COVID-19 Home Isolation in Italian College Students: The Role of Physical Exercise. Nutrients 2020; 12:E3660. [PMID: 33260711 PMCID: PMC7759990 DOI: 10.3390/nu12123660] [Citation(s) in RCA: 44] [Impact Index Per Article: 11.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/10/2020] [Revised: 11/24/2020] [Accepted: 11/26/2020] [Indexed: 12/23/2022] Open
Abstract
Social isolation has adverse effects on mental health, physical exercise, and dietary habits. This longitudinal observational study aimed to investigate the effects of mood states and exercise on nutritional choices, on 176 college students (92 males, 84 females; 23 ± 4 years old) during the COVID-19 lockdown. During 21 days, nutrition and exercise were daily monitored, and the mood states assessed. A factor analysis was used to reduce the number of nutritional variables collected. The relationships between exercise, mood and nutrition were investigated using a multivariate general linear model and a mediation model. Seven factors were found, reflecting different nutritional choices. Exercise was positively associated with fruit, vegetables and fish consumption (p = 0.004). Depression and quality of life were, directly and inversely, associated with cereals, legumes (p = 0.005; p = 0.004) and low-fat meat intake (p = 0.040; p = 0.004). Exercise mediated the effect of mood states on fruit, vegetables and fish consumption, respectively, accounting for 4.2% and 1.8% of the total variance. Poorer mood states possibly led to unhealthy dietary habits, which can themselves be linked to negative mood levels. Exercise led to healthier nutritional choices, and mediating the effects of mood states, it might represent a key measure in uncommon situations, such as home-confinement.

Abstract
OBJECTIVE To explore the motivational transfer between physical activity (PA) and body-related eating cues, through self-determined motivations to exercise (SDM Ex) and regulate eating (SDM Eat). DESIGN Cross-sectional. SETTING Participants completed an online inventory on PA and eating behaviors and motivations in 2017-2018. PARTICIPANTS A convenience sample of 300 adults (71% women; 34.4 ± 10.7 years; 23.2 ± 3.4 kg/m2), recruited through Facebook and cooperating Portuguese gyms. VARIABLES MEASURED Moderate-to-vigorous physical activity (independent), SDM Ex and SDM Eat (mediators), and body-related eating cues (dependent) variables assessed through validated self-reported measures. ANALYSIS Structural equation modeling and serial mediation procedures were used to test the hypothetical model. RESULTS Physical activity was positively associated with SDM Ex, which was, in turn, associated with SDM Eat, which in turn positively predicted reliance on hunger/satiety cues and (more strongly) body-food choice congruence. The path through exercise and eating motivations was the leading mediating path in the PA and body-food choice congruence association. CONCLUSIONS AND IMPLICATIONS This study lends support to the motivational transfer hypothesis between SDM Ex and SDM Eat in normal-weight adults, suggesting that more physically active individuals present higher SDM Ex and SDM Eat, and therefore, greater attentiveness to body-related eating cues and necessities. Encouraging PA might also improve individuals' eating self-regulation, especially if self-determined motivations are targeted in future interventions.

Abstract
Emotional eating (EE) is prevalent among women and is associated with obesity. The coronavirus 2019 (COVID-19) pandemic and mandatory quarantine increased the risk of mental symptoms and, inferentially, emotional eating (EE). We investigated the EE prevalence and predictors during this pandemic. Overall, 638 women, ages 18-39, completed an online survey incorporating the Emotional Eating Scale, Perceived Stress Scale, Generalized Anxiety Disorder-7 Scale, Patient Health Questionnaire-9, Pittsburgh Sleep Quality Index, and Global Physical Activity Questionnaire. We asked about nutrition and collected data on weight, height, and pandemic responses. Most respondents (47.2%) reported low EE; 40.4% were "moderate" and 12.4% "high" emotional eaters; 42.8% reported depression, 27% anxiety, 71% moderate stress, and 12.5% severe stress. The main EE indicators/predictors were fat intake (β = 0.192, p = 0.004), number of meals (β = 0.187, p < 0.001), sugar consumption (β = 0.150, p < 0.001), body mass index (β = 0.149, p < 0.001), stress (β = 0.143, p = 0.004), energy intake (β = 0.134, p = 0.04), and fast food intake frequency (β = 0.111, p < 0.01). EE score correlated negatively with increased family income (β = -0.081, p = 0.049). Higher stress correlated with worse sleep, less sleep, and less physical activity. Emotional eating is common among young Saudi women during the pandemic. We recommend healthy food choices and increased physical activity to improve sleep and mitigate stress.

Abstract
INTRODUCTION Behavioral (nonsurgical/nonpharmacologic) weight loss treatments have been overwhelmingly unsuccessful beyond the short term. Rather than incorporating accepted behavioral change theory, most have inadequately relied on providing exercise and nutrition information. Although adherence is a challenge, exercise has emerged as the most robust predictor of sustained weight reduction. However, exercise might be more associated with long-term weight loss through the relationship of its associated psychological changes with improved nutrition than through direct effects of energy expenditures, which are typically minimal in deconditioned individuals. OBJECTIVE To facilitate improved helping methods through a proposed theory-based causal chain model in which supported exercise predicts sustained weight loss through successive changes in exercise-related, then eating-related, self-regulation, self-efficacy, and mood. RESULTS Segments of the model predict that 1) exercise and eating behaviors will be sequentially improved through increased self-regulatory skill use and self-efficacy and 2) exercise-induced mood improvements will foster greater self-regulation and reduced emotional eating. Short-term psychosocial changes can be leveraged to carry over to longer-term changes and maintained weight reductions. Suggested interventions emerging from the model and supporting research include using self-regulation to enable a habit of regular moderate exercise, facilitating a transfer of self-regulatory skills from an exercise to eating context, and leveraging mood improvements associated with manageable volumes of exercise to improve eating behaviors. CONCLUSION The model presents an evidence-based explanation of the exercise-weight loss association through psychosocial mechanisms. It also informs the development of practical methods to facilitate sustainable reductions in weight and health risks in adults with obesity.

Abstract
Maintaining loss of weight beyond an initial 6-9 months remains problematic, with research indicating little recent progress. A poor understanding of how and when prior weight loss, behavioral changes, and psychosocial predictors are associated with long-term weight changes persists. To better-inform behavioral treatments for long-term success with weight loss, women with obesity (N = 86; Mage = 48.6 years) volunteered for research incorporating community-based weight-management treatments. They were assessed at months 6, 12, and 24 on theory-based psychosocial and behavioral factors, and over 24 months on weight. Considering the included times and temporal ranges, it was found that change in weight from month 6-24 was the strongest predictor of 24-month weight change, and physical activity and fruit/vegetable intake at month 24 best predicted that change in weight. Self-regulation, self-efficacy, and mood at month 24 best predicted both physical activity and fruit/vegetable intake at month 24, with body satisfaction also a significant predictor of physical activity. From these data, mediation analyses found that the predictions of long-term weight loss by scores of self-regulation, self-efficacy, body satisfaction, and mood at month 24 were significantly mediated by fruit/vegetable intake and physical activity in separate equations. Findings indicated both psychosocial and behavioral targets, and timing for those targets, most indicative of long-term success with weight loss.

Eating behaviors and weight loss outcomes in a 12-month randomized trial of diet and/or exercise intervention in postmenopausal women. Int J Behav Nutr Phys Act 2019; 16:113. [PMID: 31775800 PMCID: PMC6882083 DOI: 10.1186/s12966-019-0887-1] [Citation(s) in RCA: 23] [Impact Index Per Article: 4.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/23/2019] [Accepted: 11/20/2019] [Indexed: 11/26/2022] Open
Abstract
Background Certain eating behaviors are common among women with obesity. Whether these behaviors influence outcomes in weight loss programs, and whether such programs affect eating behaviors, is unclear. Methods Our aim was to examine the effect of baseline eating behaviors on intervention adherence and weight among postmenopausal women with overweight or obesity, and to assess intervention effects on eating behaviors. Four hundred and 39 women (BMI ≥25 kg/m2) were randomized to 12 months of: i) dietary weight loss with a 10% weight loss goal (‘diet’; n = 118); ii) moderate-to-vigorous intensity aerobic exercise for 225 mins/week (‘exercise’; n = 117); iii) combined dietary weight loss and exercise (‘diet + exercise’; n = 117); or iv) no-lifestyle change control (n = 87). At baseline and 12 months, restrained eating, uncontrolled eating, emotional eating and binge eating were measured by questionnaire; weight and body composition were assessed. The mean change in eating behavior scores and weight between baseline and 12 months in the diet, exercise, and diet + exercise arms were each compared to controls using the generalized estimating equation (GEE) modification of linear regression adjusted for age, baseline BMI, and race/ethnicity. Results Baseline restrained eating was positively associated with change in total calories and calories from fat during the dietary intervention but not with other measures of adherence. Higher baseline restrained eating was associated with greater 12-month reductions in weight, waist circumference, body fat and lean mass. Women randomized to dietary intervention had significant reductions in binge eating (− 23.7%, p = 0.005 vs. control), uncontrolled eating (− 24.3%, p < 0.001 vs. control), and emotional eating (− 31.7%, p < 0.001 vs. control) scores, and a significant increase in restrained eating (+ 60.6%, p < 0.001 vs. control); women randomized to diet + exercise reported less uncontrolled eating (− 26.0%, p < 0.001 vs. control) and emotional eating (− 22.0%, p = 0.004 vs. control), and increased restrained eating (+ 41.4%, p < 0.001 vs. control). Women randomized to exercise alone had no significant change in eating behavior scores compared to controls. Conclusions A dietary weight loss intervention helped women modify eating behaviors. Future research should investigate optimal behavioral weight loss interventions for women with both disordered eating and obesity. Trial registration NCT00470119 (https://clinicaltrials.gov).

Abstract
PURPOSE OF REVIEW The purpose of this review was to examine different forms of disordered eating among individuals with excess weight, including their rates, correlates, and psychosocial treatments. RECENT FINDINGS Binge eating/binge eating disorder, loss of control eating, emotional eating, and food addiction are all fairly prevalent among individuals with excess weight. They appear to share many of the same correlates, including broader eating disorder psychopathology, body/shape/weight concerns, depression, anxiety, and low self-esteem. Behavioral, cognitive-behavioral, and third-wave (e.g., acceptance, mindfulness) therapies appear effective in improving binge eating, loss of control eating, emotional eating, associated features (e.g., weight and shape concerns), and psychological distress (e.g., depression). Certain forms of disordered eating are elevated among individuals with excess weight, and psychosocial interventions have been found effective in improving symptomatology. Empirical research examining the efficacy of treatments for food addiction is lacking, and greatly needed given both its rate and controversy.

Abstract
Inappropriately high weight in children is a persistent problem in the United States, and physical activity is often reduced in schools due to academic demands. Effective after-school programs could positively impact both physical activity and overweight/obesity, however previous reviews and meta-analyses have indicated minimal effects. Both 4- and 3-day/week versions of a social cognitive theory-driven physical activity/nutrition after-school program were evaluated against unstructured care to assess effects in children (overall Mage = 10.00 years, SD = .80). For changes over 9 months in body mass index (BMI), effects sizes (Cohen's d) were .68, .40, and .07 in the 4-day (n = 70), 3-day (n = 70), and unstructured (n = 50) groups, respectively. Similar patterns of effects were found for changes in free-time physical activity and cardiovascular endurance. Incorporating a theory-based prediction model previously supported in teens through older adults, with and without medical disorders and health-risk factors, improvements in exercise-related self-regulation and self-efficacy, and mood, significantly predicted increased free-time physical activity (R2 = .48). Effects significantly strengthened to R2 = .62 when completion/non-completion of the recommended 300 min/week of physical activity was also accounted for. Change in BMI was inversely related to physical activity change, β=-.14, p < .05. The present evaluation process indicated promising effects, and indicated theory-based targets to foster future program improvements.

Abstract
Abstract. This study tested the effects of exercise on eating behavior. The transfer hypothesis proposes that exercise leads to a generalization of healthy behavior and therefore an improved diet. The compensation hypothesis assumes that exercise leads to increased caloric intake in order to “compensate” for the energy expenditure. We tested these hypotheses for actual as well as imagined exercise. Female university employees or students (N = 227) were randomly assigned to three experimental groups: actual exercise vs. imagined exercise vs. control. After baseline data had been obtained, the participants engaged in a 5-minute experimental task and were then left alone with unhealthy snacks. Participants who had imagined themselves exercising (M = 101 kcal, SD = 128 kcal) consumed significantly fewer calories than did controls (M = 129 kcal, SD = 142 kcal), consistent with a transfer effect. Participants who had engaged in actual exercise, but had been distracted from thinking about exercise, consumed quantities (M = 127 kcal, SD = 111 kcal) similar to those consumed by controls. This study suggests that transfer effects are underpinned by psychological processes, such as goal activation, which should be investigated in the future.

Abstract
Background: The relationship between exercise and long-term weight loss is definitive. However, in deconditioned individuals, the basis of that relationship beyond minimal energy expenditures is unclear. Effects emanating from exercise’s proposed association with changes in emotional eating and its psychosocial correlates were tested. Methods: Women with class 1 (n = 67) and class 2 (n = 53) obesity, participating in a new community-based weight-loss treatment based on tenets of social cognitive theory, were assessed at baseline and Months 3, 6, 12, and 24 on weight and measures of exercise outputs, emotional eating, eating self-regulation, and negative mood. An exercise-support component was provided for 2 months prior to group nutrition-change sessions. Results: Improvements from baseline were significant on all measures but did not significantly differ by group. Although not for the initial 3 months, changes in exercise significantly predicted weight changes over 6, 12, and 24 months from baseline. However, only 26%–31% of the lost weight was directly attributable to exercise-related energy expenditures. Changes in emotional eating significantly mediated the exercise–weight-loss relationship, and changes in self-regulation and mood significantly mediated the exercise–emotional eating relationship. Conclusions: Findings supported exercise’s role in long-term weight loss primarily through psychosocial factors.

Metabolic effects of resistance or high-intensity interval training among glycemic control-nonresponsive children with insulin resistance. Int J Obes (Lond) 2017; 42:79-87. [PMID: 28757639 DOI: 10.1038/ijo.2017.177] [Citation(s) in RCA: 18] [Impact Index Per Article: 2.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/11/2017] [Revised: 07/03/2017] [Accepted: 07/14/2017] [Indexed: 02/06/2023]
Abstract
BACKGROUND Little evidence exists on which variables of body composition or muscular strength mediates more glucose control improvements taking into account inter-individual metabolic variability to different modes of exercise training. OBJECTIVE We examined 'mediators' to the effects of 6-weeks of resistance training (RT) or high-intensity interval training (HIT) on glucose control parameters in physically inactive schoolchildren with insulin resistance (IR). Second, we also determined both training-induce changes and the prevalence of responders (R) and non-responders (NR) to decrease the IR level. METHODS Fifty-six physically inactive children diagnosed with IR followed a RT or supervised HIT program for 6 weeks. Participants were classified based on ΔHOMA-IR into glycemic control R (decrease in homeostasis model assessment-IR (HOMA-IR) <3.0 after intervention) and NRs (no changes or values HOMA-IR⩾3.0 after intervention). The primary outcome was HOMA-IR associated with their mediators; second, the training-induced changes to glucose control parameters; and third the report of R and NR to improve body composition, cardiovascular, metabolic and performance variables. RESULTS Mediation analysis revealed that improvements (decreases) in abdominal fat by the waist circumference can explain more the effects (decreases) of HOMA-IR in physically inactive schoolchildren under RT or HIT regimes. The same analysis showed that increased one-maximum repetition leg-extension was correlated with the change in HOMA-IR (β=-0.058; P=0.049). Furthermore, a change in the waist circumference fully mediated the dose-response relationship between changes in the leg-extension strength and HOMA-IR (β'=-0.004; P=0.178). RT or HIT were associated with significant improvements in body composition, muscular strength, blood pressure and cardiometabolic parameters irrespective of improvement in glycemic control response. Both glucose control RT-R and HIT-R (respectively), had significant improvements in mean HOMA-IR, mean muscular strength leg-extension and mean measures of adiposity. CONCLUSIONS The improvements in the lower body strength and the decreases in waist circumference can explain more the effects of the improvements in glucose control of IR schoolchildren in R group after 6 weeks of RT or HIT, showing both regimes similar effects on body composition or muscular strength independent of interindividual metabolic response variability.

Abstract
OBJECTIVE To improve understanding of directionality in the dynamic relationships among psychosocial predictors of behavioral changes associated with weight loss. METHODS In women with obesity participating in a new behavioral weight-loss treatment that emphasizes physical activity (n = 53; body mass index = 34.7 ± 3.3 kg/m2), mediation and moderated-mediation models were fit to assess directionality in the self-efficacy-self-regulation change relationship and additional effects of mood change and its basis on fruit/vegetable intake and physical activity behaviors through month 6 and from months 6 to 24. RESULTS Self-regulation was a stronger predictor of change in self-efficacy than vice versa. Mood change did not moderate the relationships significantly between changes in self-efficacy and/or self-regulation, and weight loss behavior. Emotional eating significantly changed mediated relationships between changes in mood and fruit/vegetable intake through month 6 (95% confidence interval, -0.05 to 0.00). CONCLUSIONS AND IMPLICATIONS Findings clarified relationships of self-efficacy, self-regulation, and mood in the prediction of weight loss behaviors, and informed behavioral treatments for improved outcomes.

Annesi JJ, Mareno N. Psychosocial changes as correlates of weight regain vs. continued loss within 2-year trials of a self-regulation-focused community-based intervention. Clin Obes 2017; 7:22-33. [PMID: 28079977 DOI: 10.1111/cob.12173] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/26/2016] [Revised: 11/07/2016] [Accepted: 11/29/2016] [Indexed: 11/29/2022]
Abstract
Although health-enhancing weight reductions are associated with behavioural treatments initially, a trajectory towards full regain typically begins within 6-9 months. Women with obesity (body mass index = 30-40 kg m-2 ) who lost at least 3% of their baseline weight within two trials of a new cognitive-behavioural treatment incorporating physical activity prior to changes in eating behaviours, and either regained ≥50% of that weight over 2 years (Regain group, n=32) or continued to lose weight (ContinuedLoss group, n = 34), were assessed from months 6 to 24 on changes in weight-loss behaviours and psychosocial predictors of those behaviours derived from established behavioural theories. For the Regain group, significant decreases in physical activity and fruit/vegetable intake during months 12-24, from both months 6 to 24 and 12 to 24 in eating- and physical activity-related self-regulation and from months 6 to 24 in eating-related self-efficacy (i.e. feelings of ability), were found. No significant behavioural or psychosocial changes were found over those times in the ContinuedLoss group. Changes in self-regulation and self-efficacy completely mediated the relationship between changes in fruit/vegetable intake and group (Regain vs. ContinuedLoss) (McFadden's R 2 = 0.19 and 0.20, respectively), with self-regulation independently contributing to the explained variance. Changes over both months 6-24 and 12-24 in self-regulation significantly mediated the relationship between changes in physical activity and group membership (McFadden's R 2 = 0.24 and 0.27, respectively). Findings suggested that approximately 6 months after treatment initiation would be a suitable time to intervene with some bolstering methods, while approximately 12 months post-initiation would be most applicable for others.
