Filter by:The primary objective of the current proposal is to determine the effectiveness of long-term consumption of Fibersym® RW for improving blood lipids (including cholesterol) and body composition. The overall goal of this clinical research is to determine the potential effects that RS4 consumption may have on the prevention of obesity and obesity-related diseases. Fiber in the form of RS4 will be used for the proposed study, given that fiber has been shown to have many beneficial effects on modifiable risk factors associated with obesity-related diseases. Using a long-term randomized-controlled intervention design, blood lipids (total cholesterol, LDL-c, HDL-c, triglycerides) and body composition will be assessed. The investigators anticipate reductions in cholesterol and body fat percentage following 8-weeks of Fibersym® RW consumption.
This study will evaluate the effects of retrieval-extinction (R-E) training on responding to high calorie foods including self-report craving, physiological responding, and high calorie food intake in adults with overweight/obesity. R-E training aims to update the memories that associate cues (i.e., high calorie food) with reward (i.e., consumption). R-E training involves "retrieving" these cue-reward associative memories through brief presentation of relevant cues, resulting in instability of the memories and providing an opportunity to be updated via reconsolidation. Presenting relevant cues while not allowing consumption (i.e., extinction training) during reconsolidation can modify the unstable cue-reward memories, resulting in lasting reductions of craving and intake. This study will be the first to test the effects of R-E training on craving for and intake of high calorie foods in humans. To examine the effects of R-E training on food craving, physiological response (heart rate, skin conductance, salivation), and food intake, 150 adults with overweight/obesity will complete baseline food cue-reactivity and intake tasks in the lab. Participants will be randomized to observe high calorie food cues (i.e., "retrieval" of food cue-reward memories; R-E training group) or non-food cues (i.e., no retrieval of food cue-reward memories; extinction control group) and engage in 60 min of extinction training for high calorie foods. R-E/extinction control training will occur on two consecutive days and four follow-up food cue-reactivity sessions through 3 months. Weight will be assessed at each session and in-lab food intake at 1- and 3-months. Recent food/drink intake will also be assessed at each session. Some participants (n=75) will complete a pilot portion of the study involving real-world data collection of naturally-occurring food cues, craving, and food intake via smartphone. It is hypothesized that: (1) R-E training (vs. extinction control) will decrease high calorie food cue-reactivity (self-report craving, heart rate, skin conductance, salivation) and intake assessed in the lab, as well as self-report craving and food intake assessed in the real world; and (2) decreased high calorie food cue-reactivity will be a mechanism through which R-E training reduces high calorie food intake at follow-up. The Principal Investigator will explore associations between lab and real-world cue-elicited craving and food intake, and the effect of R-E training on weight.
This study determines whether different forms of ketones supplemented prior to a meal lower the triglyceride (fat) content in the blood of overweight and obese individuals. Through a randomized crossover design, participants (n=15) will participate in each of the following three experimental groups (no treatment control, ketone ester, ketone salt), with a 5-14 day washout period between each experimental visit.
This project offers the opportunity to obtain detailed measurements on the health of body composition, metabolic health, and intestinal microbial diversity in overweight adults; moreover to provide information about the effects of physical exercise on them. The aim of the research is to advance in the understanding of the mechanisms induced by physical exercise, which includes the measurement of nutritional parameters, clinical and biochemical biomarkers of hepatic/cardiometabolic health, as well as the application of differential proteomics technologies by means of Arrays of cytokines and intestinal microbiome, making this study a novel and pioneer in sensitive areas of primary health care in Latin America.
The purpose of this study is to test two versions a weight loss program potentially suitable for implementation in Africa. A successful method would have widespread application in low-income countries, with the potential to improve world health.
The purpose of this study is to determine whether robotic assistance can help facilitate adherence, engagement, and weight loss in participants enrolled in a behavioral weight loss program. All participants will be enrolled in the same Web-based weight loss program and take part in "robotic assistance sessions" either early or late in the five-week study. These robotic assistance sessions involve speaking one on one with a robot about diet-related progress.
The study investigates the effects of high intensity interval training (HIIT) versus continuous training (CT), combined or not with fasting, on capillary density, microvascular function, cardiometabolic risk markers, functional capacity, and quality of life, in overweight or obese sedentary women with cardiometabolic risk factors. The use of HIIT could promote greater improvements in these parameters than CT. Furthermore, the positive effects of exercise may increase when it is performed in the fasting state, compared to exercise performed in the fed state.
The purpose of this research study is to learn about the effect of Liraglutide (Victoza) on the fat of the heart and some fat cells in blood.
The purpose of this study is to see what the effects of using one or two additional diabetes drugs (dapagliflozin and exenatide-LAR) are on blood sugar levels in patients who are taking insulin. This research study is being done to investigate which of these commonly-used medications, medication combinations or increasing insulin dose is better.
This study assesses weight loss from the Endoscopic Vertical Gastroplasty or Fogel Gastroplasty (FG). The purpose of the study is to: - Document that weight loss occurs (12 months) - Determine if it alters general wellbeing (emotionally and physically)
