Abstract Objective Cognitive interventions may be effective in weight loss. The purpose of this study was to assess if cognitive reappraisal (CR; reframing the meaning of a stimulus in order to change the resulting emotional response), can reduce food attentional bias (FAB) using the Visual Dot Probe (VDP) paradigm. Method 126 participants (age 27 ± 5.8) were randomly assigned either to a CR or to a control (CN) group. After assessing baseline VDP levels for FAB, participants either wrote sentences that discourage eating fattening food or neutral sentences. Next, all participants performed the VDP post intervention. Participants also self-reported on disordered eating behaviors and their height and weight were charted. We hypothesized that CR would reduce FAB and that disordered eating would moderate the association between group and FAB. Results FAB decreased post intervention, specifically in the CR group. The bulimia sub-scale showed an interaction between bulimic eating, time and group. Among those who were high on the bulimia scale, the CR group showed lower FAB post-intervention compared to the CN group. Discussion This study suggests that CR may decrease the attentional bias toward high-calorie food compared to other strategies in the general population and among people with high bulimia measures, in particular. Plain English summary Obesity has a negative impact on many aspects of life and much research is dedicated to trying to better understand behaviors concerning obesity. People are prone to focus their attention on things that are of importance to them, such as food. When people focus their attention on food, we call this Food Attention Bias (FAB). Cognitive reappraisal (CR) interventions involve the person's conscious cognitive change of the meaning of the situation aiming to consequently change the emotional response to it, such as saying to yourself “I shouldn’t eat this because I don’t want to get fat”. CR has been found to be helpful in lowering FAB using brain imagining techniques but has not yet been studied in cognitive processes. Our study used a Visual dot probe paradigm (VDP) to assess the efficacy of CR on lowering FAB. Two groups, one using CR and a control group were assessed twice on FAB, using the VDP paradigm. Compared to the normal condition, the CR intervention helped reduce FAB. This reduction was especially significant for people with a higher tendency for bulimic behavior. The VDP paradigm, utilizing CR. can be expanded to help build an intervention aimed at reducing FAB over time. This, in turn might bring to weight reduction. People with bulimic tendencies might especially benefit from CR interventions when dealing with weight loss.

After assessing baseline VDP levels for FAB, participants either wrote sentences that discourage eating fattening food or neutral sentences. Next, all participants performed the VDP post intervention. Participants also self-reported on disturbed eating behaviors and their height and weight were charted. We hypothesized that CR would reduce FAB and that disturbed eating would moderate the association between group and FAB. Results: FAB decreased post intervention, specifically in the CR group. The bulimia sub-scale showed an interaction between bulimic eating, time and group. Among those who were high on the bulimia scale, the CR group showed lower FAB post-intervention compared to the CN group. Discussion: This study suggests that CR may decrease the attentional bias toward high-calorie food compared to other strategies in the general population and among people with high bulimia measures, in particular.

Abstract Background/Introduction Obesity and its comorbid conditions (i.e. type II diabetes mellitus, atrial fibrillation, coronary artery disease, hypertension, etc...) is a growing burden globally, however, the current treatments (i.e. bariatric surgery, intragasrtic balloons and/or pharmaceutical therapy) pose substantial risks or are contraindicated for various populations. Transcatheter bariatric embolotherapy of left gastric artery by reducing “hunger” hormones from the gastric fundus is a procedure for weight loss that has been growing in prominence over the last several years, however, to date no randomized-controlled trial has been conducted until our study. We studied TBE in a double-blind, sham procedure, first in human RCT of patients (pts) with obesity. Purpose The purpose of this study was to assess the safety and efficacy of TBE for weight loss in obese patients as well as to evaluate metabolic changes. Methods After IV propofol, eligible pts (age 21–60; BMI 35–50 kg/m2) were randomized 1:1 to Sham (skin nick & 1 hr wait) or TBE. All pts received Lifestyle Therapy (behavioral and diet education). Study staff following the pts were also blinded to treatment. Blood samples for gastrointestinal hormones were collected in EDTA tubes containing a protease inhibitor cocktail and frozen per local laboratory standards. All collected samples were assessed together in two batches at the end of the study. The hormones analyzed included ghrelin, GIP, GLP-1, Visfatin, resistin, PAI-1 (total), Leptin, and C-Peptide. An Oral Glucose Tolerance Test (OGTT) and a diabetes assay was performed at baseline and at 6- and 12-months post-intervention. Note, while diabetes was an exclusion criterion for this study, pre-diabetes was not. Results 44 pts were enrolled, of which 40 pts were randomized equally to the groups, with no major complications in either group. TBE demonstrated superior weight loss over the control group at 6- and 12-months post-intervention in both intention-to-treat and per-protocol analyses. At 6 and 12 months, the TBE group demonstrated a clinically meaningful decrease in glucose 1-hour post-fasting by OGTT. GIP levels in the TBE group increased at a mean of 21%, indicative of an improvement in pre-diabetic milieu. Circulating plasma visfatin levels decreased 20% at 6 months and 26% at 12 months in the TBE group indicating a decrease in body fat. C-Peptide levels were noticeably increased in the TBE group at 6 months possibly indicating improvements in insulin sensitivity and beta-cell function. Conclusion(s) TBE is safe and results in clinically significant weight loss and demonstrated a positive effect on glucose homeostasis in pre-diabetic patients.

AbstractNon-alcoholic fatty liver disease (NAFLD) is a significant public health concern closely linked to obesity, affecting an estimated 25% of adults in Europe. Understudied in Ireland, the aim of this research was to examine the effects of a 12-week multi-component dietary intervention on weight loss and markers of liver injury in Irish NAFLD patients in tertiary care. Biopsy confirmed NAFLD patients (n = 27) were recruited from St James’ Hospital in Dublin, Ireland. Consenting participants underwent a 12-week moderate-intensity intervention incorporating weekly group nutritional education, behavioural change and group support, as well as individualised advice and weigh-ins from a trained nutritionist. Control group participants were given routine clinical care. All participants were clinically reviewed before, immediately after, and 3 months post intervention. Individuals (n = 12) with histological evidence of steatohepatitis underwent a repeat liver biopsy on completion of the intervention. Detailed dietary assessment was performed using both a 4-day diet diary (4DDD) and a novel, recently validated, short food frequency questionnaire (SFFQ) designed specifically to assess habitual intakes of food items related to NAFLD. Nutrient intakes were analysed using myFood24TM dietary analysis software, and the Mediterranean diet quality score (MDQS) was used to assess the overall change in dietary patterns. Of the 15 participants who completed the intervention, 80% (n = 12) achieved a weight loss exceeding 5%, with 47% (n = 7) achieving > 7%. There were significant improvements from baseline to week 12 in the intervention group for the majority of clinical parameters including HbA1c (p = 0.0054), liver enzymes (ALT, p = 0.0108; GGT, p = 0.0001) and transient elastography (kPA, p = 0.0308; CAP, p = 0.0081). However, these results failed to maintain significance when analysed compared to controls. The overall dietary pattern was significantly improved after 12 weeks as assessed by the MDQS (p = 0.03), with no apparent compromise in micronutrient intake despite the energy reduction. Reductions in energy, saturated fat, carbohydrate and sugar intakes at 12 weeks, were maintained at three months follow up. Analysis of pre- and post-intervention liver biopsies in the intervention group demonstrated a clinically significant improvement in NAS score (p = 0.0273), attributable to reductions in hepatic steatosis (p = 0.0078). A significant correlation was observed between improvement in liver histology and change in sugar intake (r = 0.7534, p = 0.0093). Although results were somewhat limited by small sample size, nutritional education achieved beneficial dietary changes that persisted after the intervention ceased. Notably, achieving reductions in sugar intakes may be particularly beneficial in reducing the severity of hepatic steatosis in Irish adults with NAFLD.

Predictors Of Weight Loss

Intentional weight loss among overweight and obese adults (body mass index ≥ 25 kg/m2) is associated with numerous health benefits, but weight loss maintenance (WLM) following participation in weight management programming has proven to be elusive. Many individuals attempting to lose weight join formal programs, especially women, but these programs vary widely in focus, as do postprogram weight regain results. We surveyed 2,106 former participants in a community-based, insurance-sponsored weight management program in the United States to identify the pre, during, and post-intervention behavioral and psychosocial factors that lead to successful WLM. Of 835 survey respondents (39.6% response rate), 450 met criteria for inclusion in this study. Logistic regression analyses suggest that interventionists should assess and discuss weight loss and behavior change perceptions early in a program. However, in developing maintenance plans later in a program, attention should shift to behaviors, such as weekly weighing, limiting snacking in the evening, limiting portion sizes, and being physically active every day.

Weight Losses

Treatments to induce weight loss for the obese patient centre on the achievement of negative energy balance. This objective can theoretically be attained by interventions designed to achieve a reduction in energy intake and/or an increase in energy expenditure. Such ‘lifestyle interventions’ usually comprise one or more of the following strategies: dietary modification; behaviour change; increases in physical activity. These interventions are advocated as first treatment steps in algorithms recommended by current clinical obesity guidelines. Medication and surgical treatments are potentially available to those unable to implement ‘lifestyle interventions’ effectively by achieving losses of between 5 kg and 10 kg. It is accepted that the minimum of 5% weight loss is required to achieve clinically-meaningful benefits. Dietary treatments differ widely. Successful weight loss is most often associated with quantification of energy intake rather than macronutrient composition. Most dietary intervention studies secure a weight loss of between 5 kg and 10 kg after intervention for 6 months, with gradual weight regain at 1 year where weight changes are 3–4 kg below the starting weight. Some dietary interventions when evaluated at 2 and 4 years post intervention report the effects of weight maintenance rather than weight loss. Specific anti-obesity medications are effective adjuncts to weight loss, in most cases doubling the weight loss of those given dietary advice only. Greater physical activity alone increases energy expenditure by insufficient amounts to facilitate clinically-important weight losses, but is useful for weight maintenance. Weight losses of between half and three-quarters of excess body weight are seen at 10 years post intervention with bariatric surgery, making this arguably the most effective weight-loss treatment.

Background: Worldwide, approximately 95% of obese people who follow diets for weight loss fail to maintain their weight loss in the long term. To fill this gap, mindfulness-based interventions, with a focus on mindful eating, are promising therapies to address this challenging public health issue. Aim: To verify the effects of the Mindfulness-Based Eating Awareness Training (MB-EAT) protocol by exploring quantitative and qualitative data collected from Brazilian women. Methods: A single-group, mixed-methods trial was conducted at a public university with adult women ( n = 34). Four MB-EAT groups were offered weekly for 2.5-h sessions over 12 weeks. Pre- and post-intervention assessments included body mass index (BMI) and self-report measures of anxiety, depression, mindfulness, self-compassion, and eating behaviour. Qualitative information was collected using focus groups in the last session of each group, including both participants and MB-EAT instructors. The qualitative data were examined using thematic analyses and empirical categories. Results: Twenty participants (58.8%) completed both pre- and post-intervention assessments, with adequate attendance (≥4 sessions). There was a significant average decrease in weight of 1.9 ± 0.6 kg from pre- to post-intervention. All participants who had scored at the risk level for eating disorders on the EAT-26 decreased their score below this risk level. Qualitative analysis identified that participants were able to engage a more compassionate perspective on themselves, as well as greater self-awareness and self-acceptance. Conclusion: The MB-EAT showed preliminary efficacy in promoting weight loss and improvements in mindfulness and eating behaviour. This intervention promoted effects beyond those expected, extending to other life contexts.
