Filter by: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.
The goal of this study is to learn about how children's sleep is related to their eating behaviors the next day, and to learn about factors that relate to eating behaviors and sleep health that are specific to preadolescent children living in rural communities.
Food prepared outside of the home tends to have a high energy content, and high levels of nutrients of concern (sodium, fat, saturated fat and sugar), especially when compared to home-cooked food. A number of studies suggest that when energy density of a food is manipulated it has a linear effect on energy intake, because consumers tend to eat a constant weight of food. However, recent observational research suggested that up to approximately 1.5-2kcal/g, individuals are relatively insensitive to changes in energy density, and there is no indication of compensation through altering meal size. However, upwards of approximately 1.5-2kcal/g, the authors proposed that individuals compensate for increases in energy density by selecting and consuming smaller meal sizes. The investigators aim to measure participant's consumption (in grams and kilocalories) of three meals at low, medium and high energy densities, and to measure later food intake to observe any evidence of later compensation in response to experimental condition
The goal of this observational study is to explore if different and specific profiles can be identified in adults with binge eating disorder (BED) depending on their additional eating pathology, emotion regulation and executive functions. The main questions it aims to answer are: - Is there different and specific subgroups of patients with BED according to baseline profiles in emotion regulation, executive function and additional eating pathology (including restriction, chaotic eating, grazing and eating on external cues)? - Are subgroups of individuals with BED (based on identified profiles) associated with outcome at end of treatment and follow-up? - What is the trajectories in remission rates of specific symptom dimensions (eating disorder pathology, emotion regulation, executive function, and depressive symptoms) in individuals with BED and is there specific trajectory profiles in these dimensions? - Is early changes in specific symptom dimensions (eating pathology, emotion regulation, executive function, or depression) associated with outcome of BED? Participants will be asked to fill in questionnaires before treatment as usual, 10 weeks into treatment, at end of treatment and at 6- and 12-month follow-up.
Art therapy; Art therapy is an integrative mental health service that enriches the lives of individuals, families, and communities through active art practices, the creative process, applied psychological theory, and human experience in a psychotherapeutic relationship. It is a therapeutic method used in the form of sessions to improve self-esteem and self-esteem." Art therapy used to develop emotional resilience, increase insight, develop social skills, reduce and resolve conflicts and distress seeks to both find an outlet for complex and intense emotions and It allows them to be verbally expressed at an intellectual level, and aims to develop and grow self-awareness within themselves.
Athletes in low energy availability (LEA) are at increased risk of developing the Relative Energy Deficiency in Sports (RED-S) syndrome (Mountjoy et al., 2018). LEA is a mismatch between dietary energy intake and exercise energy expenditure, leaving inadequate energy to support physiological functions, and the RED-S syndrome increases the risk of impaired health and performance (Drew et al., 2018, Sesbreno et al., 2022a, under review; Sesbreno et al., 2022b, in preparation; & VanHeest et al., 2014). Although athletes with eating disorders are at high risk, many more may be vulnerable due to uninformed practices for weight loss and/or failure to match energy intake to energy demands for exercise (Wells et al., 2020). Despite efforts to better detect athletes in LEA/RED-S;there is no research on the effectiveness of dietary interventions to influence energy intake in international elite/world-class athletes tomitigate risk of LEA (De Souza et al., 2021; Elliott-Sale et al., 2018; Heikura et al., 2021; Melin et al., 2014; Stellingwerf et al., 2021;Stenqvist et al., 2021 & Rogers et al., 2021). Therefore, it is important to investigate dietary interventions to influence eating habits to improve energy availability in elite athletes. Energy deficit associated with LEA in elite athletes may be accompanied by insufficient carbohydrate intake for training demands (Burke et al., 2011; Heikura et al., 2017; Sesbreno et al., 2021). Unfortunately, there is a paucity of information on the influence of sport nutrition education interventions on dietary intake in elite international (tier 4) and world-class (tier 5) athletes (McKay et al., 2022). However, recent findings suggest an association between nutrition knowledge and energy/carbohydrate availability in young female endurance athletes (Kettunen et al., 2021). This finding may offer a cost effective approach to lower the risk of LEA since education programs have shown to improve nutrition knowledge in athletes (Tam et al., 2019). However, an increase in nutrition knowledge may not always lead to a parallel increase in energy/carbohydrate intake (Heikkila et al., 2019). Indeed, the influence of nutrition education programs on improving dietary intake in athletes is reportedly equivocal (Boidin et al., 2021). However, the differences in intervention design with lack of guidelines on standardized and/or validated methods to assess sport nutrition knowledge and eating habits in elite athletes have made comparisons difficult for generalized interpretation. Fortunately, the new arrival of the Platform to Evaluate Athlete Knowledge of Sports Nutrition Questionnaire (PEAK-NQ) and the Athlete Diet Index (ADI) offer validated methods for assessing sport nutrition knowledge and eating habits in elite athletes (Capling et al., 2021 and Tam et al., 2021). Nevertheless, it is also important to appreciate that nutrition knowledge is not the sole influencing factors to athletes' dietary habits; and recognizing additional factors affecting athletes' decisions around nutrition is critical. A multitude of factors influence food choices in elite athletes (Thurecht et al., 2019). It ranges from sensory appeal, emotional influences, influence of others, weight control, performance among others (Thurecht et al, 2020). Interestingly, a moderate intercorrelation between nutritional attributes of the food and weight control, performance as well as food values and beliefs were reported (Thurecht et al., 2021). In fact, restraint eating behaviour have been associated with LEA, body weight and physique morphology (Jurov et al., 2021; Sesbreno et al., 2021; Sesbreno et al., 2022c in preparation; Sesbreno et al., 2022d, in preparation & Viner et al., 2015). Clearly, multiple factors influence dietary habits, and therefore, it is important to consider how education interventions are developed to influence dietary outcomes in elite athletes. The Capability, Opportunity, Motivation - Behaviour (COM-B) model describes the importance of influencing 3-sources of behaviour to consistently alter habits (Michie et al., 2011). This was reiterated by sport nutritionists who characterized enablers and barriers to nutrition adherence in high performance sports (Bentley et al., 2019). In a case study, dietary interventions that targeted all 3-source behaviours was associated with improvements in dietary intake, including energy availability as an elite rugby player prepared for his 1st professional season (Costello et al., 2018). Therefore, a sport nutrition education program that accounts for all source behaviours may be necessary to improve eating habits intake to lower the risk of LEA/RED-S in elite international and world-class athletes during the competitive season. Overall Aim: Investigate whether elite athletes' nutrition knowledge and dietary intake can improve through an education intervention to lower the risk of low energy availability.
The investigators will conduct a full dissemination and implementation study using a type 2 hybrid effectiveness-implementation design. The investigators will conduct this study in the community and work with two vegan soul food restaurants. The investigators propose to examine the effectiveness and implementation of community-delivered, 3-month NEW Soul program among participants (N=228). Using a randomized design, the investigators will assess effectiveness of two delivery approaches: (1) In-person, live weekly classes with restaurant vouchers (intervention) or (2) restaurant voucher-only (active control). The investigators will also conduct a cost-effectiveness analysis of delivering the online intervention plus voucher vs. voucher-only with the outcome of cost/change in weight, healthy eating index, and quality adjusted life year. Lastly, the investigators will examine the implementation of the NEW Soul study with participants and intervention staff.
The present study is a pilot study examining whether long-term sourdough bread consumption reduces energy intake and blood lipids levels over a period of 4 weeks in free-living normalweight and overweight participants.
Most individuals with obesity become so before age 35 and adolescent's unhealthy dietary patterns, specifically high intake of ultra-processed foods and poor overall diet quality, may contribute to energy overconsumption and weight gain. The overall objective of this research is to establish proof-of-concept for altered reward processing measured by brain response to ultra-processed foods, an increase in ad libitum energy intake, and adverse effects on executive function in response to an ultra-processed diet (81% total energy) compared to a diet emphasizing minimally processed foods in individuals aged 18-25 years.
