NCT ID: NCT06365385 Recruiting - Healthy Clinical Trials

Postprandial Metabolic and Appetite Responses to Different Food Intake Sequences in Athletes

Start date: April 22, 2024
Phase: N/A
Study type: Interventional

Emerging evidence suggests that following a 'carbohydrate-last meal pattern', wherein foods rich in protein, fat, fiber, and/or polyphenols are consumed before sources of simple carbohydrate (CHO) in a meal, results in reduced postprandial glycaemic responses than the reverse food order or a co-ingestion pattern. This effect has been observed across the spectrum of glucose tolerance, from patients with diabetes to individuals with normal glucose tolerance (Kuwata et al., 2016; Nishino et al., 2018; Lu et al., 2019; Sun et al., 2020). Furthermore, reduced glucose excursions have been linked to decreased subsequent hunger and energy intake (Lu et al., 2019; Wyatt et al., 2021). However, to date, no studies on food intake sequence have targeted athletes, despite their increased CHO demands (Thomas et al., 2016) which could expose them to repeated episodes of hyperglycaemia and high glycaemic variability, known to increase the risk of adverse cardiovascular outcomes and all-cause mortality (Loader et al., 2015; Cavero-Redondo et al., 2017; Faerch et al., 2018). Additionally, athletes often face pressure to meet body composition standards and may benefit from strategies that enhance satiety and craving control. Finally, there is reason to believe that better glycaemic control could lead to improved performance, given that enhancements in endurance activities have been observed with a low-glycemic-index diet compared to a high-glycemic-index diet (Heung-Sang Wong et al., 2017). Therefore, this randomised crossover trial is part of a wider project which seeks to explore the impact of food intake sequence on metabolic health and performance in athletes. Specifically, this trial aims to investigate the acute, postprandial metabolic and appetite responses to consuming an identical meal in two intake sequences (CHO-last versus CHO-first) in athletes, while in the resting state.

NCT ID: NCT06105853 Recruiting - Clinical trials for Alcohol Use Disorder

Neurobehavioral Profiles of Adaptive Stress Responses in Individuals With Alcohol Use Disorder

A03
Start date: December 1, 2023
Phase: N/A
Study type: Interventional

The goal of this observational study is to investigate longitudinal stress response profiles and adaptive versus non-adaptive stress responses in alcohol use disorder. The main questions the projects aims to answer are: What are the neurobehavioral underpinnings of adaptive stress responses and resilience to repeated stress exposure with regards to: - alcohol craving? - alcohol use? - their modulation by prior stress exposure, social interactions, coping strategies and individual health behavior? Participants will: - be exposed to an established experimental stress-induction protocol, the Trier Social Stress Test - be exposed to their favorite drink in a bar lab environment - be assessed using fMRI to determine their neural alcohol cue reactivity, response inhibition, and emotion processing - conduct an ambulatory phase to assess stressors, alcohol craving, substance use and details on social interactions, health behavior and coping strategies using ecological momentary assessment tools.

NCT ID: NCT05666726 Recruiting - Pain Clinical Trials

State-dependent Interoception, Value-based Decision-making, and Introspection

Start date: July 25, 2023
Phase: N/A
Study type: Interventional

Background: Negative emotional states can affect a person s behavior as they make decisions. For example, hunger may make people more impatient; they may then make riskier choices. Other negative emotional states that can change behavior include stress, pain, and sadness. By learning more about how emotions affect thinking and behavior in healthy people, researchers hope to better understand how to identify and treat people with mental disorders. Objective: To learn how negative emotions affect the brain and decision-making behavior. Eligibility: Healthy people aged 18 to 55 years. Design: Participants will have 3 clinic visits in 3 weeks. Participants will fill out questionnaires. They will be asked about their personal history, their personality, and state of mind. For 2 visits, participants will be assigned to different groups. Each group will experience 1 type of emotional stressor: Some participants will watch a video. Some will have to do arithmetic problems. Some will have heat applied to an arm or leg. Some will experience cold by immersing their hand in ice water. For a snack craving test, some will be tempted by food after a 4-hour fast. During these tests, participants will have sensors attached to their bodies. They will be videotaped. Saliva samples will be collected. After the stressors, participants will do tasks on a computer. They will need to make choices. Some participants will perform these decision-making tasks while lying in a brain scanner for functional magnetic resonance imaging. The brain scan involves lying on a table that slides into a cylinder that takes images of the brain.

NCT ID: NCT05277714 Recruiting - Obesity Clinical Trials

Neurofeedback Based on Near-infrared Spectroscopy as a Therapy for Food Addiction in Obese Subjects.

CaDOb
Start date: May 25, 2022
Phase: N/A
Study type: Interventional

The hypothesis is that the increase in dlPFC brain activity via near-infrared spectroscopy-based Neurofeedback (fNIRS-based NF) training based on near-infrared spectroscopy would allow an improvement of the eating behavior, thus promoting a long-term weight loss in obese subjects. Patients will be trained during a month with 8 NF sessions and results based on clinical data and different questionnaires results will be compared between inclusion and 3 months later

NCT ID: NCT04902469 Recruiting - Craving Clinical Trials

Cognitive and Affective Mechanisms Underlying an Olfactory Approach to Modify Cigarette Craving

OdorCrave
Start date: December 1, 2021
Phase: N/A
Study type: Interventional

The proposed study uses fMRI and behavioral measures in and outside the laboratory to investigate the neurobehavioral mechanisms underlying the impact of pleasant olfactory cues (OCs) on cigarette craving. The investigators plan to randomize 278 participants to a pleasant OC condition or an odor blank (neutral) condition and due to anticipated drop out expect to run 250 adult (half female) smokers, including both daily and nondaily smokers through the protocol. This study involves three visits. In the first visit, participants will complete a baseline breath carbon monoxide reading, a brief odor threshold test, and complete a series of self-report measures. In the next session, participants who are 8-hrs deprived of nicotine will undergo a 60-minute fMRI scan that will include structural, resting state, and task-based data collection. The fMRI task involves completing a series of tasks designed to index responses linked to key neural networks found to relate to addiction (e.g., reward processing, working memory). Participants will also be exposed to smoking cues to heighten craving and then depending on their condition (randomly assigned) will either receive a pleasant or neutral (odor blank) OC. In the third session, behavioral data will be collected to test the impact of either a pleasant or neutral OC on cigarette craving using self-reported urge and behavioral measures linked to craving. Finally, for pilot purposes designed to offer data for a subsequent clinical study (beyond this study), participants will additionally complete a 7-day ecological momentary assessment (EMA) protocol in which they will monitor cigarette craving and initial data will be collected outside the laboratory to evaluate the impact of OCs on naturally occurring craving. It is hypothesized that pleasant OCs will disrupt craving brain states and attenuate craving (as compared to neutral olfactory cues). Further, it is hypothesized that individual variation in neural responses to cognitive and affective tasks will reveal variation in mechanisms underlying pleasant OC craving reduction and that individual differences will moderate pleasant OC-induced craving relief. Finally, it is also expected that emotional responses to pleasant OCs will mediate the impact of OCs on craving and smoking-related processes.

NCT ID: NCT04338178 Recruiting - Obesity Clinical Trials

Efficacy of a Cognitive - Affective - Addictive Based Intervention to Decrease Food Craving in Obese Patients.

OBESADEM
Start date: November 15, 2021
Phase: N/A
Study type: Interventional

Since the 80's, the prevalence of obesity has more than doubled and despite progression of knowledge, interventions usually lead to a transient reduction in body weight that is not maintained in the long-term. These failures in weight management may be partly explained by an incomplete understanding of obesity risk and maintaining factors. Behavioral and neurobiological similarities between use of high palatable foods and addictive psychoactive drugs have led to the concept of food addiction. Addiction is defined as a loss of control of use, and its persistence despite accumulation of negative consequences. Craving, an uncontrollable and involuntary urge to use, has shown to be a core determinant of persistent use and relapse in addiction. Recent studies have established that food addiction, craving and emotional eating concern a large part of obese patients, and that food addiction may explain some negative outcomes of weight loss treatments, such as unsuccessful attempts to reduce calories and early termination of treatment programs. Recent advances in neuropsychiatry suggest that an imbalanced interplay between cognitive and affective processes impedes self-control and enhances over- or under-controlled behaviors. In the field of food intake and weight management, there is increasing evidence that besides environmental factors, inefficient executive functions and emotion regulation skills are salient phenomena underlying habit-forming processes that are present in eating disorder subtypes as well as obesity. This has led some authors to consider disordered eating behaviors as 'allostatic' reactions by which the modulation of food intake is used by vulnerable individuals to adjust to craving, maladaptive cognitive and/or emotional strategies. Current recommendations emphasize the need for translating these discoveries into treatments to promote healthy eating and weight management. Over the last 5 years, a growing base of clinical and behavioural studies have indicated that, individually, Cognitive-Behavioural Therapy (CBT), Emotional Skills Training (EST), and Cognitive Remediation Therapy (CRT) are promising techniques to decrease disordered eating behaviors, including craving. The investigators hypothesize that addition to treatment as usual (TAU) of a specific program targeting executive functions, emotional regulation, and addictive-like eating behaviors, could have a beneficial impact on reported food craving, and improve weight management among obese patients.
