  abstract  = {Background Eating in absence of hunger is quite common and often associated with an increased energy intake co-existent with a poorer food choice. Intuitive eating (IE), i.e., eating in accordance with internal hunger and satiety cues, may protect from overeating. IE, however, requires accurate perception and processing of one's own bodily signals, also referred to as interoceptive sensitivity. Training interoceptive sensitivity might therefore be an effective method to promote IE and prevent overeating. As most studies on eating behavior are conducted in younger adults and close social relationships influence health-related behavior, this study focuses on middle-aged and older couples. Methods The present pilot randomized intervention study aims at investigating the feasibility and effectiveness of a 21-day mindfulness-based training program designed to increase interoceptive sensitivity. A total of N = 60 couples participating in the NutriAct Family Study, aged 50-80 years, will be recruited. This randomized-controlled intervention study comprises three measurement points (pre-intervention, post-intervention, 4-week follow-up) and a 21-day training that consists of daily mindfulness-based guided audio exercises (e.g., body scan). A three-arm intervention study design is applied to compare two intervention groups (training together as a couple vs. training alone) with a control group (no training). Each measurement point includes the assessment of self-reported and objective indicators of interoceptive sensitivity (primary outcome), self-reported indicators of intuitive and maladaptive eating (secondary outcomes), and additional variables. A training evaluation applying focus group discussions will be conducted to assess participants' overall acceptance of the training and its feasibility. Discussion By investigating the feasibility and effectiveness of a mindfulness-based training program to increase interoceptive sensitivity, the present study will contribute to a deeper understanding of how to promote healthy eating in older age.},

  abstract  = {As intuitive eating (IE) is characterized by eating in response to internal cues of hunger and satiety and by monitoring the effect of food on the body, it has been hypothesized to lead to healthy food intake. Evidence concerning its link to food intake is scarce. This experimental study investigated the relationship between IE and food intake in middle-aged adults. Fifty-five participants aged 50-70 years completed the Intuitive Eating Scale 2 to measure IE. Usual consumption frequency of fruits, vegetables, snacks and sweets was assessed as a measure of healthy self-reported food intake. A taste test of apples, carrots, coated peanuts and chocolate was conducted as a measure of healthy and total laboratory food intake. Regression analyses were performed using Frequentist and Bayesian methods of inference. In line with our hypothesis, IE was associated with healthier self-reported food intake (medium effect size: f(2) = 0.24). The data were 49.80 times more likely under H-1 than under H-0. Contrary to our hypotheses, IE was neither associated with healthy nor total laboratory food intake in classical regression analyses. The accompanying Bayes factors revealed inconclusive evidence. Data only allow drawing cautious conclusions about the different relationship between IE and the self-reported consumption frequency of the foods vs. the amount of these foods consumed in a single test situation. Future studies combining different measures of IE (e.g., behavioral paradigms) and self-reported (e.g., diet quality, portion sizes) and laboratory (e.g., repeated taste tests with pre-selected foods) food intake are warranted to further explore their relationship.},

  abstract  = {Self-regulation is a dispositional skill of regulating attention and emotion to attain a certain goal. Poor self-regulation is associated with a higher body mass index (BMI) and is a risk factor for the development of obesity. Intuitive eating, an adaptive eating style characterized by eating in response to internal cues of hunger and satiety, is associated with a lower BMI. Using cross-sectional data, this study examined whether intuitive eating mediates the relationship between self-regulation and BMI in a community sample of adults. Participants (N = 530) completed the Self-Regulation Scale, the Intuitive Eating Scale-2 with its facets Unconditional Permission to Eat (UPE), Eating for Physical Rather Than Emotional Reasons (EPR), Reliance on Hunger and Satiety Cues (RHSC) and Body-Food Choice Congruence (B-FCC). They also self-reported their height and weight. Using percentile bootstrap resampling procedures, the simple mediation analysis showed an indirect relationship between self-regulation and BMI through intuitive eating. The multiple mediation analysis revealed that EPR and B-FCC, but not UPE and RHSC, mediated the relationship between self-regulation and BMI. Intuitive eating seems to play an important intermediating role in the relationship between self-regulation and BMI. Regarding weight management interventions, it could be useful to promote intuitive eating, especially for individuals with low self-regulation. Prospective studies are needed to explore the causal and temporal relationships among self-regulation, intuitive eating and BMI.},
