The study is a single center, randomized, double blind, placebo controlled; parallel-group repeated measures design. Subjects will be randomly assigned to either Saxenda® or placebo group after baseline assessments. The study will consist of a 4-week partial dose period (Liraglutide 0.6mg, 1.2mg, 1.8mg, 2.4 mg) and a 12-week full-dose (Liraglutide 3.0 mg) period. The placebo group will administer equivalent volumes of the pre-filled solutions from pen-injector at the same time, using the same method during this period. The study proposes to identify factors contributing to early weight loss response in a Saxenda® treatment program. Specifically, the proposed experiments will help determine if Saxenda® changes brain functional Magnetic Resonance Imaging Food Cue Reactivity (fMRI-FCR) and whether the magnitude of that change is associated with changes in behavioral and physiological variables (hunger, satiety, cravings and weight loss).
The overall goal is to identify trends and longitudinal associations in psychosocial, food-related, and cardiometabolic risk factors that can guide public health priorities and future research needs aimed at reducing cardiovascular-related disparities in Puerto Rico. To this end, investigators will establish 'PROSPECT: Puerto Rico Observational Study of Psychosocial, Environmental, and Chronic disease Trends', an island-wide, longitudinal population cohort of 2,000 adults (30-75 years) in PR recruited with a multi-frame sampling of probabilistic plus community approaches, and assessed in a network of several partner clinics across the island. The study will collect comprehensive data on multiple psychosocial, dietary, and food-related factors, CVD biological markers, and medical record data, with follow-up at 2-years, and will assess variations by urban-rural area and by timing before-after Maria.
The objectives of this trial are to assess the effects of interactions between genetic factors and diet with various macronutrient intake on the metabolic disorders, obesity and type 2 diabetes risk, prevention, development and progress.
Aim of the study was to investigate the effects of testosterone replacement therapy on components of metabolic syndrome, vascular function and morphology, grade of non-alcoholic fatty liver disease (NAFLD), bone mineral density (BMD) and health-related quality of life.
Obesity is associated with changes in the composition of the intestinal microbiota, and the obese microbiome appears to be more efficient in harvesting energy from the diet. Fecal microbiota transplantation (FMT) represents a clinically feasible way to restore the gut microbial ecology, and has proven to be a breakthrough for the treatment of recurrent Clostridium difficile infection. The therapy is generally well tolerated and appeared safe. No clinical studies have assessed the dosage of FMT in obese subjects.
Background: Systematic reviews conclude that Internet and mobile interventions can significantly change lifestyle in a short time span. The applicant has developed a collaborative eHealth tool (LIVA) that has led to a significant and clinically relevant weight loss of 5.4 to 7.0 kg over 12 to 20 months in primary care settings. The objective of this study is to develop and evaluate a model targeting long-term effects using eHealth coaching assisted by machine learning-generated advice intervention for overweight patients at risk of developing diabetes as well as current type 2 diabetes (T2D) patients in a primary care setting. Methods and analysis: Randomized controlled trial with 1-year intervention and 1-year maintenance. The primary outcome is weight loss and the secondary outcome is reduced HbA1c level. The study will comprise 340 overweight patients of which 170 will have T2D. Individual data will be obtained from clinical measurements, questionnaire data, registered from the collaborative eHealth tool, as well as other registry data at baseline and at 6, 12 and 24 months. The core of the intervention is the establishment of an empathic relationship and ongoing real-life coaching using the LIVA app (working together with native iOS and Android) and Internet for patients combined with an effective coaching module supported by machine learning methods. The intervention will be compared with usual care.
The aim of this study is to look at how the study medicine behaves in the participant's body and how it is removed from the participant's body. The study compares Japanese and Caucasian people who are normal weight, overweight or with obesity. The participants will either get NNC0174-0833 (a potential new medicine) or placebo (a "dummy" medicine similar to the study medicine but without active ingredients) - which treatment any participant gets is decided by chance. Participants will get 1 injection by a study nurse at the clinic. The injection will be with a needle in a skin fold in the participant's stomach area. The study will last for about 4 months, but duration of participation for any participant will last up to about 2 months. The participants will have 8 clinic visits with the study staff.
The proposed pilot study will examine cooking as an intervention target for weight control in overweight adults. The study will also examine whether interventions designed to promote cooking at home can increase participants' sense of food agency, and overcome common barriers to cooking at home such as time scarcity and budget constrictions. The study will utilize a cooking pedagogy designed to not just teach participants the basics of cooking different foods, but how to be efficient, mindful cooks. If cooking class participation positively impacts diet and health outcomes, it will bolster the case for promoting cooking at home as a health behavior for multiple populations.
For weight loss to occur, energy intake needs to be reduced to incur an energy deficit. One dietary strategy that may facilitate weight loss is consuming a diet low in dietary energy density (ED). It is hypothesized that a diet low in ED, which can be achieved by a high intake of low-ED foods, low intake of high-ED foods, or a combination of the two, will allow a greater amount of volume of food to be consumed relative to energy consumed, which can assist with reducing energy intake. To understand how best to lower the ED of the diet, it is important to understand the relationship between low-ED and high-ED foods. Behavioral economics is a framework that provides a foundation to understand that eating behaviors can be substitutes for each other. Substitute eating behaviors are two behaviors that change in the opposite direction of each other (i.e. one behavior increases as the other behavior decreases). If low-ED and high-ED foods are substitutes for each other, in situations in which low-ED food intake increases, high-ED food should automatically decrease, and vice versa. If they are not substitutes, when low-ED food intake increases, high-ED food intake should remain unchanged, and when high-ED food intake decreases, low-ED food intake should remain unchanged. When low-Ed and high-ED foods are not substitutes for each other, purposeful change in intake for both low- and high-ED foods need to occur to best lower dietary ED. Thus, the purpose of this study is to investigate if low-ED foods and high-ED foods substitute for each other. Healthy weight adults will be served a meal over 4 sessions, with each meal containing 5 different food items. The foods in the meal will vary in ED: low-ED = 0 to 1.0 kcal/kg; medium-ED = 1.1 to 2.9 kcal/kg; high-ED = > 3.0 kcal/g. For the 4 sessions, the meals will include: 1) 3 low-ED foods, 0 medium-ED foods, 2 high-ED foods; 2) 3 low-ED foods, 1 medium-ED food, 1 high-ED food; 3) 1 low-ED food, 2-medium ED foods, 2 high-ED foods; and 4) 1 low-ED food, 3 medium-ED foods, and 1 high-ED food.
The long-term goal is to develop effective, evidence-based lifestyle interventions to prevent and treat childhood obesity and related co-morbidities. The short-term goal, and the purpose of this application, is to quantify appetite and neural mechanisms of food reward in overweight/obese (OW/OB) sedentary youth and to quantify changes following the implementation of a physical activity intervention. The central hypothesis is that appetite becomes dysregulated at low levels of physical activity via neural reward pathways, and appetite control will improve following a long-term exercise intervention. The investigators consider this project a pilot study designed to generate data to be used for future external funding opportunities, demonstrate collaboration between researchers, and test the feasibility of the protocols.
