Filter by:High food motivation among children is trait-like and increases risks of unhealthy dietary intake and obesity. Scientific knowledge of how parenting can best support healthy eating habits and growth among children who are predisposed to overeating is surprisingly limited. This investigation will identify supportive food parenting approaches for obesity prevention that address the needs of highly food motivated children.
Scientific knowledge of the cognitive-developmental processes that serve to support children's appetite self-regulation are surprisingly limited. This investigation will provide new scientific directions for obesity prevention by elucidating cognitive-developmental influences on young children's ability to make healthy food choices and eat in moderation.
Background: Obesity is chronic disease with high prevalence rates, functional disability and difficult long-term management. Anxiety is one of the most common psychological disorders in obesity, and when associated with other factors such as emotional eating and emotional dysregulation, it impairs treatment and interferes with lifestyle changes. Finding an intervention that improves the eating behavior of these patients and facilitates adherence to obesity treatment, associated with less emotional distress, is of great clinical interest. Objective: The aim of this study is to evaluate the effectiveness of the Mindful Eating (ME) intervention on neurocognitive and behavioral outcomes in patients with obesity and anxiety compared to the control group with exposure to videos promoting quality of life. Methods: A five-weeks randomized clinical trial will be performed with 52 patients in adulthood. The Mindful Eating intervention group will receive an online protocol with one meeting per week. This is a protocol that has been adapted for five weeks and consists of a group intervention with 10-15 participants. Mindfulness, Mindful Eating and Self-Compassion training will be based on the Eat for Life protocol. The control group will receive five videos of psychoeducation, one topic per week. After, all participants will receive lifestyle advices, a first-line "treatment-as-usual" to obesity. There will be a face-to-face assessment with anthropometric, behavioral and biological measurements pre and post-intervention. The outcomes may help in understanding the mechanisms underlying the change in eating behavior, in order to direct new therapeutic strategies for the treatment of anxiety and obesity comorbidities.
The first few months of life are a critical time for setting the health trajectory of both infants and mothers. It is essential that guidance provided to new families be based on the most rigorous scientific evidence available. Beef serves as a highly nutrient-rich option for lactating women. Plant-based beef products have similar nutrient profiles, and some consumers perceive them as a healthier alternative to traditional beef. This study aims to understand the different effects that beef and plant-based beef have on breastmilk composition, maternal glycemic control, maternal intake and satiety, and infant intake. Understanding the differences between beef and plant-based beef can help parents make informed decisions about optimal nutrition for their infants and themselves.
The study will test a model of biobehavioral mechanisms involved in the development of a system of emotion, attachment, and nutritive intake in the mother-infant dyad and the association of this system with maternal feeding behavior, child eating behavior, dietary intake, and adiposity. To participate in this study the infant must also be enrolled in long-term observational study, NCT06039878.

The goal of this interventional study is to measure the blood levels of the gut hormones LEAP2 and acyl ghrelin (AG), appetite and food intake after consuming liquid meals of different caloric sizes, in healthy adults with and without obesity. AG is a stomach-derived homone that increases appetite, and LEAP2 a liver-gut derived hormone that decreases appetite, which interferes the action of AG ant its receptor in the brain called the growth hormone secretagogue receptor (GHSR). Blood levels of AG and LEAP2 change in opposite directions after food intake (AG decreasing, LEAP2 increasing). AG is formed from an inactive version of hormone called desacyl ghrelin (DAG). Previous studies have shown that greater food intake leads to a greater decrease in blood levels of total ghrelin (AG + DAG), but this has not been studied for changes in blood AG or LEAP2 after eating. Blood levels of AG and total ghrelin when fasted and after food intake are lower, while blood levels of LEAP2 are higher, in adults with than those without obesity. The main study questions are: 1. Are there greater increases in blood levels of LEAP2 and greater decreases in blood levels of AG after consuming larger meals (by amount of calories they contain)? 2. Are greater decreases in appetite after connsuming larger meals related to greater increases in blood levels of LEAP2 and greater decreases in blood levels of AG? 3. Are greater decreases in food intake at a buffet lunch after consuming larger meals eaten a few hours previously related to greater increases in blood levels of LEAP2 and greater decreases in blood levels of AG? 4. Do the above findings differ between adults without obesity and with obesity? Healthy adults (without and with obesity) will consume liquid meals containing different amounts of calories (0, 600, 1200, 1800 kcal, of identical total volume) after an overnight fast and have measurements of blood LEAP2 and AG and appetite ratings from 0 to 180 min, and have food intake at a buffet lunch measured at 180 mins.
Bariatric surgery is the most effective treatment for severe obesity, yet a significant percentage of patients achieve suboptimal results or present long-term weight regain. Given the strong association between poor outcomes and post-surgery psychological factors, it is crucial to implement post-surgical psychological interventions. This randomized controlled trial aims to compare the efficacy of a novel, cost-effective, and timely-personalized treatment delivering strategy (stepped-care) with two different intensities 1) low-intensity intervention delivered by Facebook®, and 2) high-intensity program delivered online. It is also intended to study predictors, outcome moderators/mediators, and the underlying mechanisms of weight regain. Participants' assessment will include measures of pathological eating behavior, psychological impairment, negative urgency, and emotional regulation.
In post-menopause, most women gain weight, and obesity rates are more prevalent in this particular group. In addition, there is an increased risk of cardiovascular disease, cancer, and diabetes. Given that this weight gain can be related to risk behaviours, healthy weight management (such as an increase in physical activity or healthy eating) is crucial to promote a healthy weight and well-being. The ME-WEL (MEnopause and WEigth Loss) project (ref. SFRH/BD/144525/2019), entails an eHealth intervention for weight management and well-being in post-menopausal women with overweight or obesity, based on two theoretical models of behavioral change - the Health Action Process Approach (HAPA), and the Health Belief Model (HBM), and applying the Behaviour Change Techniques Taxonomy (BCTT). This group's eHealth intervention lasts 8 weeks. Each week there is a different theme to be addressed, taking into account the behavioral change models mechanisms, in articulation with different BCT´s. Subjective well-being, self-esteem, weight loss, implementation of weight management strategies, and changes in eating behavior and physical activity/exercise were evaluated, through follow-ups at 3- and 6- post-intervention.
