Filter by:The goal of this clinical trial is to examine the impact of price decreases based on energy content in a full-service restaurant on immediate dietary consumption (in terms of kilocalories (kcals), sugar, fat, and salt intake) and dietary consumption the rest of the day following the intervention; and whether the intervention effects differ based on socioeconomic position (SEP). Participants will be asked to visit the restaurant twice. At visit 1, participants will receive a control study menu with the existing pricing structure of the restaurant. At visit 2, participants will receive the same study menu with the pricing intervention introduced. For comparative purposes a smaller subgroup of participants will receive the control menu at both visit 1 and 2 to allow the researchers to estimate whether any pre-post changes occur in the absence of a pricing intervention (and whether change differs by SEP).
Cognitive Behavioral Therapy (CBT) is used for a group of techniques in which there is a combination of a cognitive approach and a set of behavioral procedures. The basic principle of CBT can be described as follows: emotional and behavioral responses, as well as motivation, are not directly influenced by situations, but by the way in which these situations are usually processed. The worker is any person who has a work activity, regardless of being inserted in the formal or informal market. And, nightshift work, due to its wide application and demand, for technical, social and economic reasons is a topic of great relevance today. However, it can lead to health risks, both in biological and psychological functioning, among other emotional problems, causing greater propensity to stress, anxiety crisis and emotional tiredness. In the food and nutrition units, where the organization of work is strongly guided by Taylorist-Fordist principles, structured based on routines, technical standards and organization charts for the meals production, giving attention and dedication to the behaviors and habits of employees, become some strategies for maintaining and improving motivation for work and quality of life in this environment. Objective: to evaluate the effects of an intervention to change eating behavior on the perception of quality of life and eating habits of night workers in food and nutrition units. Method: This is a research project, involving a systematic review (study I) and a clinical trial (study II). The systematic review aim to investigate whether there is a difference in eating behavior between workers, the one that works during the day and the other at night. The second study will consist of two groups; one control and one intervention. The research will consist on a web-based strategies, with two evaluative moments, before and after intervention. To assess the eating behavior outcome, the Dutch Eating Behavior Questionnaire (DEBQ) will be used; for eating practices, the Self-Applicable Scale for Food Assessment will be included, according to the Recommendations of the Food Guide for the Brazilian Population. For analysis of quality of life, the WHOQOL-Bref, short version of the WHOQOL-100 instrument, will be used.
This study will investigate the effect of lisdexamfetamine dimesylate (LDX) on the mediating factors of reward and cognition on appetite.
Previous studies have reported that the 5-HT2C receptor agonist meta-chlorophenylpiperazine (mCPP) decreases appetite and food intake in humans1-3. 5-HT2C receptor activation inhibits dopamine and norepinephrine release in the brain4, and has also been linked to diabetes5. The specificity of the effect of mCPP on human appetite is unclear, as previous studies also reported an increase in nausea1,3. The drug has also been reported to increase anxiety and cause panic attacks when given in a bolus dose intravenously6. Previous findings in our laboratory showed that mCPP reduced appetite, increased satiety in women and enhanced memory in the P1vital® Oxford Emotional Test Battery3. Following up on these results a food intake and fMRI study was performed, in which it was observed that mCPP decreased intake of a palatable snack (hedonic eating) and dlPFC and insula BOLD responses to food pictures. Additionally it increased memory and food value responses in brain after mCPP administration (Thomas et al submitted). It is well established that eating behaviour is affected by metabolic signals (e.g. insulin, ghrelin, serotonin) and is also modulated via food reward processes7. More recently it has been proposed that eating is also modulated via higher cognitive processes such as inhibitory control, attention, and memory. However, in humans, eating behaviour seems to be a more complex process, which involves habits, long-term goals and social interaction. Thus, cognitive processes appear to play an important role in food consumption. In the proposed study the researchers investigate the effect of administering mCPP, on eating, and on metabolic, reward and cognitive processes and the potential interplay between these functions.
This study is designed to compare two types of snacks (almonds or a cereal-based snack), eaten between meals, on measures of appetite, including appetitive hormones, self-reported feelings of hunger and fullness, and food intake at a buffet meal or in the home environment. The investigators hypothesize that the acute responses of appetitive hormones to a meal challenge protocol will differ between almond and cereal-based snacks based on multivariate models of satiety that will be predictive of ad libitum food intake at a dinner meal as part of the meal challenge protocol. Further, the investigators will estimate if, under free-living conditions, self-selected and self-reported food intake will show appropriate energy compensation for the added calories of the snacks, and determine if one type of snack is superior to the other in this regard.
The purpose of the present study was to conduct a pilot RCT to test the feasibility of a physician-delivered ACT-based intervention for emotional eaters with overweight/obesity against standard care at a network of weight loss clinics. Participants were randomized to receive either standard care at the clinics or the ACT intervention.
The investigators aim to ascertain how food reward signals and eating behaviour relates to the gut-brain pathway in weight-losing patients after curative surgery for oesophageal cancer, and how this pathway responds to clinical treatment for this unintentional weight loss. The primary outcomes are the blood oxygen level dependent (BOLD) signal on functional MRI (fMRI), and the breakpoint during the progressive ratio task (PRT - a measure of eating behaviour), how these differ in response to multiple clinical treatment options, as well as how they relate to weight gain while on treatment.
