This study is a clinical study to investigate the efficacy of liraglutide compared to placebo in reducing visceral adiposity measured by MRI in overweight or obese subjects at high risk for cardiovascular disease after 40 weeks on-treatment.
This study is a clinical study to investigate the gluconeogenesis pathway related to visceral adipose tissue (VAT) in obese individuals without type 2 diabetes and the effects of empagliflozin (EMPA) on glucose homeostasis in viscerally-obese individuals using functional studies of glycerol metabolism in hepatic gluconeogenesis using a well-validated nuclear magnetic resonance (NMR) spectroscopy platform.
This study seeks to correlate microbiome sequencing data with information provided by patients and their medical records regarding obesity.
Growth hormone treatment in humans has been shown to decrease body fat. This study aims to determine what adipose tissue depots are affected by GH and what is the mechanism.
The Visceral Adiposity Measurement and Observation Study
A retrospective review of body composition changes in patients who participate in a 9-week non-invasive intensive health care provider supervised weight loss program as an overall cohort and in sub-cohorts of interest.
Studies in mice demonstrated that dietary phosphate (Pi) loading that mimic the level of US adult consumption leads to reduced spontaneous locomotor activity, exercise capacity, and reduced resting metabolic rate when in normal mice by impairing skeletal muscle mitochondrial function and fat oxidation. However, relevance of this findings in humans remains unknown.
To assess, relative to a placebo, the effects of consuming 400 mL/day or 200 mL/day of a vinegar beverage providing either 1,500 mg/day of acetic acid (in two 200 mL doses daily) or 750 mg/day of acetic acid (in one 200 mL dose daily), respectively, for 12 weeks on VAT (MRI). Thus the 2 active comparator arms 400 mL and 200 mL of vinegar will be independently tested compared to placebo.
Obesity and chronic kidney disease (CKD) are major public health problems. In contrary to observations in general population, higher body mass index in those with pre-existing CKD is associated with lower mortality. Chronic Renal Insufficiency Cohort (CRIC) is an ongoing observational study to examine the consequences of CKD with a particular focus on cardiovascular illness like myocardial infarction (heart attack) and stroke. Among CRIC study participants, the investigators propose to obtain visceral and subcutaneous adiposity and physical fitness measures and study its associations with patient-centered outcomes. This study will help the investigators understand the independent and combined effects of visceral adiposity and physical fitness on cardiovascular disease, renal disease progression and death among those with CKD. Further, it will identify mechanisms that could be targeted to reduce the detrimental effects of visceral adiposity in those with kidney disease.
The purpose of this research study is to determine whether increased intake of dietary fiber during a 12-week, low-calorie weight loss intervention affects abdominal fat change and improves cardiovascular risk factors in African-American women more than a standard weight loss intervention. The investigators are testing two main hypothesis: Hypothesis 1: Women in the high dietary fiber intervention group will lose significantly more abdominal fat around their organs than women in the standard fiber group. Hypothesis 2: Women in the high dietary fiber intervention group will have lower blood pressure, fasting glucose, fasting lipids and inflammatory factors at 3-months compared to women in the control group.
This study will compare growth hormone levels and cardiovascular risk markers in normal weight and overweight women and men. In women and men with increased abdominal weight, growth hormone (GH) versus placebo will be administered and effects on cardiovascular risk, insulin resistance and body composition will be measured.
This observational pilot study will assess the effects of water-only fasting on body composition and insulin resistance
The objective of the proposed study is to enroll women with obesity that will undergo a controlled, energy restricted feeding intervention to test the effects of chronic ethanol consumption on adipose distribution and circulating testosterone during weight loss.
The overarching goal of this study is to evaluate plasma ceramides (Cers) as early nutrition-sensitive biomarkers of metabolic health. The investigators will implement a diet and lifestyle intervention to improve cardiometabolic risk factors and test the corresponding change in Cer levels. The intervention will incorporate: a) family-level engagement, enrolling both adolescents and one parent/adult caretaker (PAC); and b) a behavior change mobile health (m-health) app, which will offer real-time support, education and monitoring of diet and activity.
In this study, the investigators will examine the effect of therapy with the Growth Hormone Releasing Hormone (GHRH) analog tesamorelin on body composition in patients with HIV lipodystrophy and central adiposity. This study is a single arm prospective study of tesamorelin therapy of patients with HIV lipodystrophy. Subjects will do body composition testing, adipose tissue biopsy, metabolic rate measurements and insulin sensitivity assessment before, 6 and 12 months after daily injections of tesamorelin 2 mg by subcutaneous injection.
The purpose of this study is to determine whether introducing almonds into the diet of overweight and obese Blacks and Hispanics improves body composition, decreases liver fat, and lowers cardiovascular disease profile.
The purpose of this study is to determine whether Restorative yoga versus stretching exercises will reduce risk factors for metabolic syndrome in adults with metabolic syndrome.
Currently, it is not known if the amount of nighttime sleep has any effect on the overall physical fitness, and on how much energy do people who have a relative with type 2 diabetes (parent, sibling, or grandparent) use to perform activities of daily living. This study will test the hypothesis that individual differences in nighttime sleep duration are related to differences in the amount of energy used to perform activities of daily living and the overall level of physical fitness of the individual.
We hypothesize that the hearts of HIV+ people with The Metabolic Syndrome use and oxidize fats and sugars inappropriately, and that this may impair the heart's ability to pump blood. We hypothesize that exercise training or pioglitazone (Actos) will improve fat and sugar metabolism in the hearts of HIV+ people with The Metabolic Syndrome. This study will advance our understanding of cardiovascular disease in HIV+ people, and will test the efficacy of exercise training and pioglitazone for improving insulin resistance, heart metabolism and heart function in this at risk population.
We are testing the safety and efficacy of a 16-wk yoga lifestyle intervention on oral glucose tolerance, fasting lipid/lipoprotein levels, body composition, cardiovascular function, quality of life, CD4+ T-cell counts and viral load in HIV-infected men and women with components of The Metabolic Syndrome. We hypothesize that a yoga lifestyle intervention will improve metabolic, anthropometric, cardiovascular disease parameters, and quality of life domains without adversely affecting immune or virologic status in people living with HIV.
This study will investigate whether etanercept will result in improved inflammatory indices, glucose tolerance and endothelial function in patients with the metabolic syndrome.
This study investigates whether blockade of TNF will result in reduced inflammatory indices in patients with the metabolic syndrome
This study will evaluate the effectiveness of ziprasidone treatment versus treatment with a standard atypical antipsychotic drug in improving insulin sensitivity and reducing excess abdominal fat storage in people with schizophrenia who are at risk for diabetes.
The purpose of this study is to determine if, in men and women with excess abdominal fat and insulin resistance, people with HIV infection respond differently than people without HIV to interventions that typically improve body fat distribution and insulin resistance. The specific interventions are: 1. Diet + exercise program. 2. Rosiglitazone treatment. 3. A combination treatment of diet + exercise program and rosiglitazone.
Due to the increased focus on education and changing lifestyle, college students are particularly susceptible to poor overall health and wellness due to inadequate sleep and poor dietary choices. This is particularly important because the behavioral choices college students make may affect their risk of chronic disease. This study will research these topics via an online survey, in person visit and stool sample.
The main purpose of this study is to see how orforglipron affects the amount of body fat compared with placebo in participants with obesity or overweight. Participation in the study will last approximately 8 months.
The proposed study is designed to test the hypothesis that in human obesity, the balance of pro- and anti-inflammatory T cells in fat tissue is in fact related to macrophage phenotype and insulin resistance, and how it is related. This study is needed to confirm whether conclusions based on studies of visceral adipose tissue in mice are indeed applicable to humans. We also want to determine the relationship between insulin resistance/hyperinsulinemia and ability to lose weight in obese individuals.
This study will investigate the safety and efficacy of the investigational use of the HydraSolve T2D™ System in improving blood glucose control and insulin resistance in patients with obesity (Class 1, BMI 30-39.9 kg/m2) and type 2 diabetes who have not achieved targeted levels of blood glucose control using oral diabetes medications. The previously FDA-cleared (for liposuction and fat transfer) HydraSolve T2D™ System will be used to perform a novel, minimally invasive laparoscopic and mini-laparotomy procedure to selectively remove excess intra-abdominal fat from the mesentery (Mesenteric Visceral Lipectomy (MVL)), while not affecting surrounding tissues. The study will include several weeks of screening for eligibility before the intervention, and 12-months of follow-up post-surgery.
Dietary manipulation is proving to be an effective lifestyle strategy to combat the obesity epidemic. Increased dietary protein is one effective strategy. For example, increased whey protein ingestion with and without exercise training is associated with enhanced weight loss, body composition and subjective hunger in overweight and obese individuals. Our findings suggest that the effects of whey protein ingestion occur independent of a calorie-restricted diet and to a greater extent in individuals following a combined exercise program of resistance exercise, sprint intervals, stretching/yoga/pilates, and aerobic exercise training compared to standard resistance training.
The aim of this study is to develop an intervention that will produce a sustained improvement in physical activity and chronic stress as a means to slow the menopause-related accumulation of visceral adipose tissue in mid-life women.
