NCT03850821
The primary goal of the Connect feasibility trial was to develop and test the feasibility of a physical activity (PA) social-climate-based intervention within pre-existing after school programs (ASPs) that targets youth social goals (e.g., building friendships through PA) and social competencies (e.g., friendship-building skills) to increase the positive PA affect, cognitions, and moderate-to-vigorous (MV) PA of underserved (i.e., low income, minority status) middle school youth. The 8-week intervention was designed to improve several key social mechanisms within ASPs overlooked in previous interventions (e.g., developing friendship and connection to peers and staff through PA; group belonging, including positive peer PA norms and tangible support) that are key predictors of youth PA and included: 1) "Get to know you" sessions aimed at providing youth guided social opportunities to foster friendship-building skills, and to promote acceptance, cooperation, contribution, and friendship affiliation, and; 2) a novel socially-oriented physical activity curriculum tailored to meet the social goals and needs of program staff and participating youth. Comparison of ASPs receiving the 8-week "Connect" intervention (N=3 ASPs) with ASPs randomized to receive the general ASP curriculum (wait-list control condition; N=3 ASPs) will yield preliminary data on the effectiveness of social mediators for improving moderate-to-vigorous physical activity (MVPA) and preventing obesity among at-risk youth that can inform future intervention design and youth programming policy. Results of this proposed project will provide the basis for conducting a large scale efficacy trial. First, it is hypothesized that the Connect program will be documented to be feasible as shown by: 1) youth's greater perceived connectedness and PA affiliation goal orientation from baseline to post-intervention; 2). changes in targeted social climate components from baseline to post-intervention as measured by systematic observations, and; 3) adequate dose and fidelity of program implementation as indicated by weekly process evaluations. Second, it is hypothesized that youth in the social climate program (vs. comparison) demonstrate greater increases in positive PA affect, cognitions, and MVPA from baseline to post-intervention.
NCT02701426
Background: Obesity increasingly affects young women and contributes to increased maternal, fetal and neonatal complications. Maternal obesity contributes to the subsequent development of childhood obesity not only through social and environmental mechanisms but also through biological processes referring to the original concept of the developmental health and disease. Data suggest that management during pregnancy through nutrition counseling and adequate physical activity will help to break the familial vicious circle of obesity. To help program to be effective it is important to understand the factors that modulate participation. However, few studies have been conducted to assess the determinants that influence participation. Goal: The main objective is to analyze 15 factors that influence participation in a program combining physical activity and nutritional counseling among pregnant women with BMI ≥ 25 kg/m2. Secondary objectives are : * to identify the data that influence adherence and to show that assiduous women will have a better control of weight gain and a reduction of maternal and fetal complications. * to understand the biological mechanisms involved Strategy and method: A prospective research evaluating the participation in an educational program, including nutritional support and adequate physical activity, will be offered to overweight and obese pregnant women. The program will last 12 weeks, and will include three workshops on diet of the pregnant and lactating women, and the young child. Physical activity sessions will be offered once a week. Fifteen independent variables likely to influence participation will be analyzed. The association between participation and the risk of maternal and fetal pregnancy complications related to obesity will be analysed. Meanwhile, more fundamental research will be considered to determine of the biological factors involved.
NCT03685656
Overweight and obesity is defined, according to the World Health Organization (WHO), by abnormal or excessive accumulation of adipose or fatty tissue that may be harmful to health. Overweight and obesity are therefore important determinants of health, which expose people to many pathologies whose consequences for individuals are not only health, but also social: stigma, prejudice, discrimination. Indeed, most overweight people have a bad image of themselves. For some people, overweight can trigger stress, malaise and disgust. To break free from this malaise and satisfy the growing desire of women to take care of their body, many products are present in the slimming beauty market. EFFANACA3GEL is a prospective, randomized, double-blind, placebo controlled study. 208 healthy volunteers will be followed for 2 months during which they will use ANACA3 slimming gel. The aim of this study is to evaluate the effects of ANACA3 slimming gel on hip and waist circumferences.

The investigators aim to develop, pilot and evaluate a new "Total Lifestyle Coaching" (TLC) program, that will address both information and behavior-change aspects of nutrition education for patients whose body mass index (BMI) exceeds 25.
NCT03798873
To assess the effect of wearing a custom-fitted, FDA-registered, Class I device, compression garment (Obesinov, S.A.R.L.) by an individual with a BMI ≥ 35 on his/her day-to-day quality of life over a period of one year. Various measures of quality of life will be taken, including assessing an individual's level of pain, mood, self-stigma and comfort with the use of a compression garment. Additionally, to assess the impact of the compression garment on activity, strength, posture and movement of an individual with a BMI ≥35 over the period of one year.
NCT03369145
The present study will investigate the effect of high-fat overfeeding on a group of liver-secreted proteins linked to worsened blood sugar control, as well as proteins involved in appetite control. Participants will consume both a high-fat diet, consisting of 50% extra calories above their daily required intake, and a control diet, consisting of their normal 'habitual' diet, with each diet lasting seven days. The diets will be undertaken in a randomised order, with a period of three weeks separating the two diets. Blood samples will be taken before and after each diet to measure blood sugar control. Further blood samples will also be taken 24 hours and 72 hours into each diet to see how levels of the liver and appetite-regulating proteins change over the course of the seven days. It is expected that blood sugar control will be worsened by the high-fat diet and this will be accompanied by increases in levels of the liver-secreted proteins and an impaired release of the appetite-regulating proteins into the blood.
NCT03711084
This study aims to examine potential differences in neurocognitive responses to food-related cues, physiological and appetite responses as well as subsequent energy intake following the consumption of preloads differing in sweetness and/ or postprandial metabolic effects in healthy normal weight subjects.
NCT01737658
Obese Adolescents will be evaluated for insulin resistance and cognitive dysfunction.
NCT03203161
While bariatric surgery is established as a safe and effective alternative with well-defined risks for severely obese adults, little has been published on its use in children. There are many unresolved questions concerning the long-term metabolic and psychological consequences of bariatric surgery in adolescents, and the difference with the adult population. The appropriate timing for bariatric surgery in young people, and the predictors of success and safety still need to be determined. The aim of this long-term prospective study is therefore to establish the safety and efficacy profile of surgical procedures and to clarify whether reductions in morbidity and mortality outweigh the risks of serious surgical complications and lifelong nutritional deficiencies.

NCT03394469
This project aims first to determine the prevalence of sarcopenia in a population of obese people of extended age group (18-70 years). In a second step, the factors determining and / or predisposing to sarcopenic obesity will be identified as well as plasmatic and urinary biomarkers specific to this phenotype.
NCT03690076
Data about human cardiac mitochondria are cruelly lacking in the literature. However, damages of the activity of these organelles are often the source of abnormal cardiac function in several pathologies. The purpose of this study is to develop a model of purified human cardiac mitochondria, to verify the purity of these organelles and to validate the authenticity of their function in acute endocarditis and obesity, two situations known to alter their activity. Animal studies have shown that microbial infection reduced mitochondrial metabolism whereas obesity increases it. The investigator's hypotheses are the following: 1) acute endocarditis, a form of cardiac microbial infection, reduces the function of human cardiac mitochondria; 2) obesity (body mass index \> 30) activates the metabolism of human cardiac mitochondria.
NCT03057873
The objective of this study is to investigate the effect of a high protein, high fiber dietary supplement on weight and fat loss in healthy overweight adults. Half of participants will receive a high protein, high fiber supplement twice a day for 12 weeks, and half of the subjects will receive a placebo (that contains the same amount of calories as the supplement) twice a day for 12 weeks.
NCT00475982

NCT02831621
Excess ectopic fat deposition is associated with development of cardiovascular and metabolic diseases. This study investigates how lifestyle interventions can have an effect on different sites of ectopic fat deposition and cardiovascular or metabolic factors. Moreover, the clinical and economic value of exercise to supplement a hypocaloric diet is investigated. Endocrinologists of the University Hospital of Antwerp, Belgium, will be recruiting women during consultations. Also, recruitment posters will be used in the University Hospital of Antwerp and the University of Antwerp. Potential participants meeting all a priori set inclusion and exclusion criteria will be randomized by minimization method to a hypocaloric diet group (usual care) or a group of hypocaloric diet combined with physical fitness training. Both groups will undergo an intake procedure in which personal goals are set and barriers to changes in behavior will be discussed. Ectopic fat deposition will be measured by imaging techniques after three and six months of intervention. Based on the known relationship between ectopic fat and cardiovascular outcomes, the short term study results will then be extrapolated to an estimation of the reduction of cardiovascular events. The following clinical outcomes will be presented: change in ectopic fat in the abdomen (visceral fat), the liver (intra hepatic lipids), skeletal muscle (intra myocellular lipids), heart (epicardial fat) after a dietary or combined (diet+physical activity) intervention. The impact of supervised exercise in addition to diet will be expressed in projected healthcare costs and quality adjusted life years.
NCT02269631
This pilot study is designed to test the effects of a high legume (dried bean) diet on hunger and other indicators of health over the course of eight weeks, compared to a more conventional healthy diet.
NCT03446235
Many kinds of wearable technology have become available, but the superiority of those devices in weight loss compared to the standard care without them is uncertain. The possible problems are long-term self-motivation, utility and validity of the device, and outcome measures in clinical trials. The connected health care with motivational interviewing as an intervention, and body composition parameters in addition to body weight as outcome measures are employed in the project. The expected outcome is that connected health care, which is more individualized approach by heath care professionals, is more effective compared to self-monitoring using wearable devices. Two types of wearable device are going to be used to monitor 1) body activity and 2) heart rate variables during exercise which reflect fitness level in this study in order to investigate appropriate monitoring parameters to predict outcome measures. The hypothesis is that addition of connected health system will result in improvement of body composition and fitness level compared to self-monitoring.
NCT02835092
