NCT04720950
The beneficial effects of regular exercise on both physical and mental health are widely known; it is a pivotal component in the treatment and prevention of many metabolic disorders, including obesity. Exercise facilitates weight management, not only by increasing energy expenditure but through its effect on appetite regulation and, therefore, energy intake. Multiple factors influence the effect of exercise on appetite regulation including body fat , gender, intensity and duration of exercise and levels of habitual physical activity . However, recently interest has grown around the impact time-of-day of exercise may have on appetite regulation . Subjective feelings of hunger follow a strong diurnal pattern, with feelings of hunger peaking in the evening and appearing lowest in the morning . Evening energy intake has been associated with increased total energy intake and body mass index Evening exercise could potentially counteract or lessen the evening hunger sensations and therefore reduce evening and total energy intake. The aim of this study is to investigate any changes in total energy intake, distribution of energy intake, and food preference on the day of and 24 -hours after a bout of moderate-intensity exercise completed in the morning or evening in a group of physically inactive adults. A total sample of 12 physically inactive adults aged 18-60 will be recruited on to the study. The study will take the form of a two-armed randomised controlled crossover trial consisting of two 48-hr overnight stays in the Human Intervention Studies Unit (HISU) at Ulster University, Coleraine, Northern Ireland. The participant information sheet will focus on the effect of morning and evening exercise on ambulatory blood pressure and exercise-induced feeling states to prevent the participants' knowledge of the true purpose of the study from influencing their feeding behaviours. Ambulatory blood pressure will be monitored for at least 24 hours after the exercise session and participants will be asked to complete questionnaires of exercise induced feeling states immediately before and after each exercise session. Participants will be briefed on the true purpose of the study following the study completion. During the visits, participants will be asked to perform 1 hour of exercise at 70% of their maximal heart rate on a motorised treadmill between either 0800-1000 or 1800-2000 on the first full day of the study appointment. Food will be provided ad libitum for the duration of the study. All food intake will be noted and covertly weighed and directly observed through security cameras in the HISU dining room and lounge areas to measure food-related behaviours, such as grazing or bingeing. A 24 hour dietary recall will be conducted at the end of each study appointment to validate recall against observed intake.
NCT04425005
The aim of this study is to assess the effect of a home-based exercise training during social isolation due to covid-19 pandemic in patients who undertook bariatric surgery.
NCT02982759
Obesity among Hispanic children in the Lower Yakima Valley of Washington State is alarmingly high. This study proposes to implement a comprehensive, multi-level intervention among children, families, the schools, and the community to combat this problem. The two year intervention will be measured by examining changes in children's body mass index.
NCT03377634
Chronic pain contributes to declining health and function in older adults; effects that are intensified by obesity and sedentary (sitting) behavior. The purpose of this study is to develop and test a novel, patient-centered intervention to reduce pain and improve physical function in older, obese adults. The study will utilize a combination of telephone based coaching and smartphone tools to deliver this novel intervention to decrease both body weight and sitting behavior. The long-term goals of this project are to test the efficacy of the intervention and to develop it as a tool for clinicians to provide outside-of-clinic patient-centered support for overweight/obese older adults with chronic pain.
NCT04143945
This study in healthy men and women looks at the injection site experience of the DV3396 pen to that of the PDS290 pens when both pens are used to deliver 0.25 mg semaglutide subcutaneously (s.c., under the skin). Participants will receive 2 single doses of semaglutide 0.25 mg on 1 day. The 2 injections will be given at least 30 minutes apart, one in each side of the stomach. Participants will be in the clinic research center for 1 day. A follow-up phone call will take place between 4 and 5 weeks after the injections were given.

NCT01527851
Introduction: Currently, bariatric surgery appears to be the most effective treatment to improve the health of morbidly obese population. However, the massive weight loss induced by this intervention can create excess loose skin in various parts of the body contributing to the feeling of failure in their desire to feel better in some patients. Several studies show that people are once again disappointed and dissatisfied with their body appearance due to the mass of unsightly loose skin that disrupts their quality of life. However, very few studies have focused on the barriers that this excess skin could create in everyday physical activity. The aim of the investigators pilot study is to assess the impact of excess skin on the practice of physical activity in women who underwent bariatric surgery and evaluate if there is a relationship between physical activity and the level and location of excess skin. Also, the investigators will explore, the benefits of plastic surgery in patients who had this intervention. Materials and methods: About twenty women who underwent bariatric surgery and a dozen who had subsequent plastic surgery will be included in this pilot study. Anthropometry, weight loss post bariatric and plastic surgery, motivational stage on the practice of physical activity, usual practice of physical activity, functional and physical ability, perceived benefits and barriers of physical activity, self-esteem and quality of life will be assessed. After analyzing the results, a group discussion will be established to further evaluate the impact of excess skin on the practice of physical activity. The evaluation will be identical for monitoring the effects of plastic surgery but the discussion group will also address the benefits and satisfaction related to plastic surgery. Expected results: Excess skin could be a barrier to physical activity by limiting the functional and physical capacity. Thus, plastic surgery could improve the practice of physical activity with a direct improvement of functional discomfort, the subjects' motivation to be physically active, perceived benefits and barriers to physical activity, self-esteem and quality of life. Issue project: This pilot project will generate data that will allow us, depending on the relevance of the results, to continue the investigators investigation with a larger cohort.
NCT02348801
Older people with diabetes will be assigned to the 1-year lifestyle program or no lifestyle program while continuing usual treatment for diabetes. The lifestyle program will consist of teaching how to practice healthy diet and regular exercise at our facility and continued into the community and home. It is hoped that the results would provide convincing proof about the usefulness of lifestyle change in older patients with diabetes.
NCT02148614
AIMS Phase 1. Verify whether the intake of LibramedR is able to induce a better endocrine and metabolic profile. Phase 2. Verify whether treatment with LibramedR for 60 days produces a better glycaemic profile after oral glucose load. SUBJECTS Will be recruited 80 obese children for phase 1 and 40 obese children for phase 2. Subjects will be randomly assigned to treatment with placebo or LibramedR with a double blind clinical trial. METHODS Experimental protocol phase 1 Each child will arrive at the UOC at 8 a.m., in fasting. A blood sample will be taken. Then patients will be given two LibramedR tablets or placebo. After 20 minutes they will be given a mixed meal (equal to 15 kcal per kg of lean body mass). Blood samples will then be taken at 30-minute intervals for the first two hours and 60 minutes for the following two hours, for the determination of metabolites and hormones for a total of 4 hours. The level of satiety will be quantified through a visual analog scale. Experimental protocol phase 2 Based on the results of the OGTT performed in recruitment phase, children will be divided into two groups: group A, children with blood glucose 2 hours after oral load higher than the median and group B, children with blood glucose 2 hours after oral load below the median. The children of group A will be randomly assigned to LibramedR treatment or placebo for 60 days, after which they will repeat Anthropometric measurements, bioelectrical impedance, OGTT and blood chemistry. They will also repeat dietary and sport anamnesis . During the 60 days, the children of both groups will receive the same dietary treatment consisting of a low-calorie and balanced diet, and recommendations to practice more sport. Every 15 days a research assistant will contact the families to reinforce treatment adherence. EXPECTED RESULTS Phase 1 LibramedR intake should cause a lower increase in postprandial blood glucose, insulin, triglycerides and a greater decrease in ghrelin levels compared to placebo treatment; Phase 2 The treatment with LibramedR should be associated with a decrease in blood glucose and insulin secretion after OGTT compared to placebo treatment.
NCT03182985
The investigators intend to measure the health impact of a dietary intervention known as time restricted feeding (TRF) on patients with metabolic syndrome (three or more of: increased waist circumference, abnormal cholesterol levels, elevated blood pressure, or elevated blood sugar). The investigators will enroll patients with metabolic syndrome who eat for ≥ 14 hours per day and will ask participants to reduce daily oral intake to 10 hours per day. The investigators will assess the impact of this dietary change using measures obtained before and after a 12 week intervention period, including body mass index, blood pressure, various lab parameters and blood sugar levels (assessed using a continuous glucose monitor). The investigators will assess for compliance with TRF using a Smart Phone application (myCircadianClock (mCC) app).
NCT03524521
Body-weight based interval training (IT) performed 3 times per week will lead to reductions in abdominal adiposity and reduce overall body fat percentage in overweight and obese sedentary adults more effectively than moderate intensity continuous training (MICT). Body-weight interval training will improve exercise capacity (peak VO2) in overweight/obese adults.
NCT03528317
The aims of this study are as follows: AIM 1: To examine the weight loss and weight maintenance efficacy of an alternate day fasting-high protein (ADF-HP) diet; AIM 2: To examine the effects of an ADF-HP diet on metabolic disease risk factors (plasma lipids, fasting glucose, fasting insulin, insulin resistance).
NCT03738540
Many behavioral weight loss interventions have been developed, but still have significant limitations in terms of achieving clinically significant, sustained weight loss. A recent study incorporating Acceptance and Commitment Therapy (ACT) in a randomized clinical trial resulted in participants who attained significantly greater 12-month weight loss in the ACT arm than those assigned to standard behavioral treatment, suggesting that ACT may have the potential to improve behavioral weight loss outcomes. The investigators have developed a novel telephone-delivered version of the ACT behavioral weight loss intervention, based on proven success using ACT telephone counseling intervention for smoking cessation.
NCT02721303
This study plans to learn more about how age and weight impact appetite and food intake. Specifically, this study is being done to see whether age and obesity impact appetite and the brain's response to food. In this study the investigators will be evaluating how participants brains respond to food images as well as your food-related behaviors and hormones. The investigators will be comparing older individuals aged 65 to 85 years who are normal weight compared to those who are obese. The Investigators will then compare older aged individuals to younger adults aged 21 to 45 years.
NCT04695418
Rice germ (RG) may be a safe and effective dietary supplement for obesity in menopause, considering its high protein content and considerable amounts of essential amino acids, good fatty acids, and fiber. This pilot randomized, blinded, parallel group, placebo-controlled pilot trial investigated the effectiveness of four weeks of RG supplementation (25 g twice a day) on body composition, measured by Dual Energy X-Ray Absorptiometry (DXA), as primary outcome, and metabolic parameters, amino acid profiles and satiating capacity, as secondary outcomes, in obese postmenopausal women following a tailored hypocaloric diet (25-30% less than daily energy requirements). Twenty-seven women were randomly assigned to the supplemented group (14) or placebo group (13). There was a significant interaction between time and group for body mass index (BMI) (p\<0.0001), waist (p=0.002), and hip circumference (p=0.01), total protein (0.008), albumin (0.005), Homeostasis Model Assessment index (p=0.04), glycine (p=0.002), glutamine (p=0.004), and histidine (p=0.007). Haber's means over time showed a clearly greater feeling of satiety for the supplemented compared to the placebo group. These findings indicate that RG supplementation in addition to a tailored diet counterbalanced the metabolic changes typical of menopause, with improvements in BMI, body composition, insulin resistance, amino acid profiles and satiety.

NCT04691583
1. Normal diet：Starting from May 20, 2018, the subjects will eat a normal diet for 4 days, with no restriction on calories and food types. The subjects are required to record their daily diet and dietary intake of calories. 2. Fast diet of High control ：From May 24, 2018, the method of fast diet was adopted on alternate days. According to the dietary records of normal diet, the normal caloric intake of each subject was calculated. Fast diet was carried out according to 2/3, 1/2, 1/3 and 1/4 of the original normal caloric intake.Each caloric stage last for 4 days, and the total cycle of fast diet was 31 days. 3. Fast diet of Low control ：After the intervention of fast diet of high control, the subjects were allowed to continue the diet fast diet every other day. It was suggested that the daily caloric intake was 600kal/ day for males and 500kal/ day for females.

NCT03207724
This study is being conducted to examine the safety of the investigational drug, Xilonix(™), in addition to standard doses of Onivyde® (nanoliposomal irinotecan) and 5- fluorouracil (5FU)/folinic acid (leucovorin) for pancreatic cancer patients with cachexia. Cachexia is a syndrome that includes involuntary weight loss and physical deterioration that can contribute to poor outcomes of cancer treatment. In other studies, Xilonix has increased lean body mass in advanced cancer patients. This increase could lead to improved weight maintenance and quality of life.
