ABSTRACT To explore the efficacy of a mindfulness-based weight loss intervention for women. Sixty-two women (ages 19-64: BMI 22.5-52.1) who were attempting to lose weight were randomised to an intervention or control condition. The former were invited to attend four 2-h workshops, the latter were asked to continue with their normal diets. Data were collected at baseline, 4 and 6 months. BMI, physical activity, mental health. At 6 months intervention participants showed significantly greater increases in physical activity compared to controls (p<.05) but no significant differences in weight loss or mental health. However, when intervention participants who reported 'never' applying the workshop principles at 6 months (n = 7) were excluded, results showed both significantly greater increases in physical activity (3.1 sessions per week relative to controls, p<.05) and significantly greater reductions in BMI (0.96 relative to controls. equivalent to 2.32 kg, p<0.5). Reductions in BMI were mediated primarily by redu

    ABSTRACT: The objective of this study was to evaluate an intervention that combined mindful eating and online pre-ordering to promote healthier lunch purchases at work. The study took place at an urban hospital with 26 employees who were overweight or obese. The design included a contemporaneous comparison with delayed-treatment control and a three-phase prospective study. A minimum 4-week baseline period preceded a 4-week full-intervention, in which participants received mindful eating training, pre-ordered their lunches, and received price discounts toward lunch purchases. In a 4-week reduced intervention phase, participants pre-ordered lunches without price discounts. Participant lunch purchases were tracked electronically at the point of purchase. The primary outcome measures were the amounts of kilocalories and fat grams in purchased lunches. In contemporaneous comparisons, the treatment group purchased lunches with an average of 144.6 fewer kilocalories (p=0.01) and 8.9 fewer grams of fat (p=0.005) compared to controls. In multivariable longitudinal analyses, participants decreased the average number of calories in their meals by 114.6 kcal per lunch and the average grams of fat by 5.4 per lunch during the partial-intervention compared to the baseline (p<0.001). At the end of the study, a moderate increase was observed in participants' overall mindful eating behaviors as compared to the beginning of the study (p<0.001). The majority of participants (92%) said they would use the pre-ordering system if offered in the future. Combined mindful eating training and online pre-ordering appears a feasible and useful worksite intervention to improve food choices by employees.

    • "Given that so many aspects of psychological inflexibility are high in severely obese women, we would expect an intervention like ACT that targets psychological flexibility to be ideal. Indeed, increasing research is suggesting that ACT is of benefit for promoting healthy behaviour and weight loss (Butryn et al., 2011; Forman et al., 2013, 2009; Juarascio et al., 2010; Lillis et al., 2009; Pearson et al., 2012; Tapper et al., 2009; Weineland et al., 2012). Our only intervention suggestion would be this: Given severely obese women experience the lowest level of striving progress in the sample, the ACT protocols might benefit from including behavioural activation very early in the intervention.

    ABSTRACT: Psychological flexibility interventions such as Acceptance and Commitment Therapy have been shown to be beneficial for weight management. Flexibility is often treated as a single, global construct, but it can also be described in terms of interrelated components (e.g., accepting, awareness, defusion, values). Are some components of flexibility of greater relevance to weight-related issues than others? We utilized a planned missing data design to assess weight status and a broad range of psychological flexibility components in a nationally representative sample of Americans (N=7884; 3748 males, 4136 females; Age: M=47.9, SD=16). Profile analyses revealed that different weight and gender groups showed different configurations of inflexibility. Underweight men showed a “defensive but active” pattern, expressing high avoidance on multiple dimensions, high levels of fusion, but also showing high hope and willingness to experience distress when pursuing goals. Overweight and obese participants did not show elevated levels of inflexibility, and indeed there was some evidence that overweight men (but not obese and severely obese men) were more flexible than other males. Severely obese participants showed elevated patterns of inflexibility across multiple indices, but this pattern differed for men and women. We conclude that psychological flexibility should not be treated as a unitary construct, and make specific suggestions for future intervention research.

    • "Next to the aforementioned explanations, the timing of the measurements could also be relevant to explain the lack of effect. Other studies evaluating the effectiveness of mindfulness based interventions on lifestyle behaviors and weight-related outcomes found effects at the immediate follow-up measurement, that is immediately after the training [18,19,21]. Both Tapper and colleagues and Van Dalen and colleagues found reduced effects at the follow-up measurement at 6 months and 3 months respectively [18,19]. "

    ABSTRACT: Overweight and obesity are associated with an increased risk of morbidity. Mindfulness training could be an effective strategy to optimize lifestyle behaviors related to body weight gain. The aim of this study was to evaluate the effectiveness of a worksite mindfulness-based multi-component intervention on vigorous physical activity in leisure time, sedentary behavior at work, fruit intake and determinants of these behaviors. The control group received information on existing lifestyle behavior- related facilities that were already available at the worksite. In a randomized controlled trial design (n = 257), 129 workers received a mindfulness training, followed by e-coaching, lunch walking routes and fruit. Outcome measures were assessed at baseline and after 6 and 12 months using questionnaires. Physical activity was also measured using accelerometers. Effects were analyzed using linear mixed effect models according to the intention-to-treat principle. Linear regression models (complete case analyses) were used as sensitivity analyses. There were no significant differences in lifestyle behaviors and determinants of these behaviors between the intervention and control group after 6 or 12 months. The sensitivity analyses showed effect modification for gender in sedentary behavior at work at 6-month follow-up, although the main analyses did not. This study did not show an effect of a worksite mindfulness-based multi-component intervention on lifestyle behaviors and behavioral determinants after 6 and 12 months. The effectiveness of a worksite mindfulness-based multi-component intervention as a health promotion intervention for all workers could not be established.
