This study will test the validity and feasibility of an smartwatch-based system to detect eating and drinking events in both laboratory and free-living conditions.
NCT05540704
The goal of this clinical trial is to test whether a new intervention works to treat eating disorders in type 1 diabetes. Participants are assigned to one of the following: (1) Acceptance and Commitment Therapy (ACT), (2) Supportive Diabetes Counseling, or (3) a 6-month Waitlist Control. Participants in the ACT and Supportive Diabetes Counseling conditions complete 12 sessions over 12-16 weeks and use their mobile phone between sessions to increase engagement and reinforce learning. The main questions are: Does treatment improve glycemic levels, eating disorder symptoms, diabetes management and diabetes distress? Does one treatment do better than the other? How do the treatments work, if they work, and for whom? Participants complete assessments that include wearing a continuous glucose sensor and activity watch, and get a blood draw to determine HbA1c. They also complete diagnostic interviews, surveys and computer tests of attention and things like heart rate and reaction time. These assessments help us better understand the types of changes that are happening and how they might influence health and well-being.
NCT07135505
The purpose of this study is to find out how early time-restricted eating affects body rhythms and improves cardiometabolic health in older adults.
NCT06947824
This trial's aim is to investigate the time-of-day effects (morning vs. evening) of fasted exercise on acute and 24h post-exercise energy intake. Specifically, we will compare the effects of fasted morning exercise (12h overnight fast) vs. fasted (6h and 12h) evening exercise on total energy intake during a post-exercise ad libitum test meal as well as on 24h (free-living) energy intake. The secondary aim is to assess subjective appetite ratings before, immediately after, and 30 min post-exercise (visual analog scale). Healthy men and women aged 18-30 years will be included.
NCT07387796
The goal of this clinical study with research procedures is to learn how stopping and restarting tirzepatide (a medication that helps regulate blood sugar and appetite) affects brain activity, behavior, and health in adults ages 18-70 who are currently taking tirzepatide. Specifically, the study aims to examine how a short pause in tirzepatide affects hunger, mood, sleep, and daily functioning; how stopping and restarting tirzepatide alters brain chemistry and brain responses to food-related images; and how these changes relate to health measures such as quality of life and emotional well-being. There is no comparison group; instead, researchers will assess changes within each participant across three time points: while taking tirzepatide, after stopping it for 3-4 weeks, and after restarting it for 6-8 weeks. Participants will attend three in-person visits lasting approximately 3-4 hours each, during which they will complete interviews, questionnaires, and cognitive tasks; provide a urine sample (pregnancy screening for females); undergo a brain scan using magnetic resonance imaging (MRI) and MR spectroscopy (MRS); and receive a kit to provide a small stool sample. Participants will also complete two brief check-in phone calls between visits and the online BrainHealth Index between sessions, which includes surveys and cognitive tasks. All changes to tirzepatide use will occur under the supervision of a study physician to support participant safety and comfort, and the total study duration is approximately 13 weeks.

NCT07094503
The purpose of this study is to test an eating disorders prevention digital chatbot program in a diverse group of adolescents.
NCT05316285
Focusing on emotions is valuable because "how a person feels, reacts, and expresses emotions can have both short-term and long-term effects on physical and mental health". This is explained by mechanisms such as reappraisal, attention regulation, self-monitoring, self-awareness, and regulation of the autonomic nervous system. Because yoga reduces negative emotions such as anxiety, anger, and depression, teens are likely to result in less conflict and stress in their lives. It is thought that it is also important for young people to accept difficult feelings and to be able to accept and approve these feelings. When negative emotions are acknowledged and witnessed, they often dissolve or transform, and the process allows the individual to learn about their limits, preferences, and needs. Processing emotions in this way allows a person to be honest with oneself and can contribute to healthier development. Therefore, yoga appears to be a useful well-being tool and practice that schools should adopt, as it can increase life skills for students such as concentration, memory, relational skills, and decision-making that are affected by emotions. Emotional well-being is important for learning in life and school. As noted earlier, research supports such a view, but more research is needed to understand how and why yoga should be offered to young people in their schools. However, it is suggested that researchers further explore the role of yoga in the management of emotions, both in terms of emotional processing and regulation of emotions. The role of yogic breathing (pranayama) as part of a holistic perspective on yoga, and specifically the role of yoga in the relationship between being with emotions, regulating emotions, and how it relates to change, should be further explored. It has been described in the literature that care should be taken to avoid possible harm to individuals associated with the use of unhealthy weight control behaviors among young adults and women with obesity. Yoga's intent to strengthen and support a positive sense of self makes it a particularly viable strategy for healthy weight management for women and those at high risk for poor body image. Finally, it has been reported that reductions in perceived stress may mediate the effects of participation in a yoga program on negative emotional and behavioral problems. It has been suggested that future studies may also assess the extent to which exposure to stress and trauma may affect youth's participation in and benefit from mindfulness and yoga interventions. Considering all the suggestions and research needs in the literature, this study was planned to examine the improvement in self-esteem, life satisfaction, body image, anxiety, depression and cognitive emotion regulation levels of university students after their participation in the yoga program provided to them in the school environment and to compare them with students who do not do yoga. In the study, it is planned to investigate the pre-exam anxiety levels of university youth who regularly practice yoga.
NCT06829862
This study aims to analyze the effects of a 3-month self-applied online program, focused on promoting healthy lifestyle habits (healthy eating and increased physical activity), on adults with obesity. Participants will be recruited by 8 doctors from 6 public Health Centers. These patients will be randomized allocated into two interventional groups: the experimental group will receive audiovisual instructions from their specialist doctor, and the control group from a doctor outside the patient. Assessment will include sociodemographic variables, body mass index, blood pressure, glycemic and lipid metabolism variables, physical activity level, adherence to the Mediterranean diet, therapeutic alliance, and health-related quality of life. The randomization process will be stratified according to BMI, therapeutic alliance, age, and sex.

The main questions it aims to answer are: * Does the ACT intervention lead to a significant difference in disordered eating behaviors among individuals at risk for eating disorders? * Does the ACT intervention lead to a significant difference in body dissatisfaction among individuals at risk for eating disorders? * Does the ACT intervention lead to a significant difference in obsessive-compulsive and borderline personality beliefs among individuals at risk for eating disorders? * Does body image flexibility significantly affect the impact of the ACT intervention on disordered eating behaviors? * Do self-as-context, cognitive defusion, and present-moment awareness significantly affect the impact of the ACT intervention on disordered eating behaviors? Participant will: Join the online 4-session ACT-based group program Fill the measures at pre-test, post-test and follow-up assessment.
NCT06928714
Pediatric feeding disorders (PFDss) affect children with age-inappropriate oral intakes lasting at least 2 weeks, associated with medical, nutritional, psychosocial or feeding skills dysfunction. Feeding is a complex function involving the digestive tract, and different structures. It evolves throughout the child's development. It involves the caregiver-child relationship. Dysfunction of one or more of these systems may be the cause of pediatric feeding disorders. PFDs affect 25% of children, 5% with severe forms. PFDs can have severe nutritional consequences. They often cause malnutrition, even undernutrition, and sometimes overweight.
NCT06012045
The current study aims to evaluate the efficacy of Enhanced Cue Exposure Therapy (E-CET) in reducing negative emotional eating (NEE), compared to an active control intervention, behavioral lifestyle intervention (BLI), in a parallel-group, participant-blinded, randomized controlled trial. The secondary aim is to evaluate whether changes in conditioned stimulus-unconditioned stimulus (CS-US) expectancies mediate the changes in NEE.
NCT05726721
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.
NCT05456516
Children from rural communities are at greater risk for obesity than children from more urban communities. However, some children are resilient to obesity despite greater exposure to obesogenic influences in rural communities (e.g., fewer community-level physical activity or healthy eating resources). Identifying factors that promote this resiliency could inform obesity prevention. Eating habits are learned through reinforcement (e.g., hedonic, familial environment), the process through which environmental food cues become valued and influence behavior. Therefore, understanding individual differences in reinforcement learning is essential to uncovering the causes of obesity. Preclinical models have identified two reinforcement learning phenotypes that may have translational importance for understanding excess consumption in humans: 1) goal-tracking-environmental cues have predictive value; and 2) sign-tracking-environmental cues have predictive and hedonic value (i.e., incentive salience). Sign-tracking is associated with poorer attentional control, greater impulsivity, and lower prefrontal cortex (PFC) engagement in response to reward cues. This parallels neurocognitive deficits observed in pediatric obesity (i.e., worse impulsivity, lower PFC food cue reactivity). The proposed research aims to determine if reinforcement learning phenotype (i.e., sign- and goal-tracking) is 1) associated with adiposity due to its influence on neural food cue reactivity, 2) associated with reward-driven overconsumption and meal intake due to its influence on eating behaviors; and 3) associated with changes in adiposity over 1 year. The investigators hypothesize that goal-tracking will promote resiliency to obesity due to: 1) reduced attribution of incentive salience and greater PFC engagement to food cues; and 2) reduced reward-driven overconsumption. Finally, the investigators hypothesize reinforcement learning phenotype will be associated due to its influence on eating behaviors associated with overconsumption (e.g., larger bites, faster bite rat and eating sped). To test this hypothesis, the investigators will enroll 76, 8-10-year-old children, half with healthy weight and half with obesity based on Centers for Disease Control definitions. Methods will include computer tasks to assess reinforcement learning, dual x-ray absorptiometry to assess adiposity, and neural food cue reactivity from functional near-infrared spectroscopy (fNIRS).
