Effects of PPAR Ligands on Ectopic Fat Accumulation and Inflammation
Metabolic Syndrome XPrediabetic StateThe relationship between obesity and insulin resistance is known, however the mechanism(s) associating obesity with insulin resistance is not well understood. Inflammation and accumulation of fat in non fat tissue (like muscle) are conditions found on obesity which could be the potential link between obesity and insulin resistance. This study is designed to test the effects of two different drugs on numerous features of the obesity and insulin resistance in subjects with impaired glucose tolerance. Impaired glucose tolerance is a condition where blood sugar is too high after drinking a sugary drink containing 75 grams of sugar. Impaired glucose tolerant subjects are insulin resistant and at risk of developing diabetes. The drugs to be used are fenofibrate and pioglitazone. Fenofibrate is used to reduce the amount of fat (triglycerides) in the blood while pioglitazone is routinely used to make the body more sensitive to insulin in patients with diabetes. The purpose of this study is to compare the effects of either of these two medications (pioglitazone and fenofibrate) alone or the combination of both on fat accumulation in body (muscle) and inflammation. The amount of fat accumulation in muscle is thought to affect insulin sensitivity. In addition, the changes in the level of proteins produced by fat tissues will be studied in response to the two medications in this study. These proteins are thought to be involved in diabetes and insulin resistance. These studies are designed to examine fundamental clinical mechanisms underlying the metabolic syndrome and diabetes.
Automated Diabetes Prevention Program
Pre-DiabetesThe objective for this pilot project is to determine the feasibility and effectiveness of the Interactive Voice Response protocol (IVR) on physical activity and eating behaviors in a group men and women who have been identified by their physician as being pre-diabetic. We hypothesize that participants receiving the IVR follow-up will have greater positive changes in their physical activity and eating behaviors when compared to those who receive only the standard-care pre-diabetes class.
Prediction Using Connected Technologies for Diabetes
Pre-DiabetesIn this study, adults with pre-diabetes will be prospectively enrolled for data collection to design prediction models that integrate electronic health record data and patient-generated activity data. Patients will be randomized to receive either a waist-worn or wrist-worn wearable device for 6 months to capture patient-generated activity data.
Inulin and Acetate Production and Human Substrate Metabolism
ObesityPre DiabetesBased on our hypothesis that orally administered resistant starch and inulin/beta glucan will be fermented into a SCFA pattern high in acetate and that this will lead to beneficial effects on human substrate and energy metabolism, we aim to address the following primary objective: To investigate the effects of an acute administration of inulin/beta glucan in combination with resistant starch on fecal and plasma acetate, as well as on fasting and postprandial substrate and energy metabolism in lean normoglycemic men and obese, prediabetic men.
Beta Glucan and Acetate Production
Pre DiabetesObesityBased on our hypothesis that orally administered resistant starch and beta glucan will be fermented into a SCFA pattern high in acetate and that this will lead to beneficial effects on human substrate and energy metabolism, we aim to address the following primary objective: To investigate the effects of an acute administration of inulin/beta glucan in combination with resistant starch on fecal and plasma acetate, as well as on fasting and postprandial substrate and energy metabolism in lean normoglycemic men and obese, prediabetic men.
Glycemic Response to Two Doses of Low Sugar Apple Juice
PrediabetesSingle center, double-blind, randomized controlled cross-over trial with four treatments and four time points. The study has three primary objectives. The first primary objective is to confirm the reduction of postprandial glycemic and insulinemic response after consumption of 500 ml glucose-free apple juice compared to 500 ml untreated apple juice as could be shown in a previous study
Study to Determine the Effect of Synbiotics in Patients With Pre-diabetes
PreDiabetesThe aim of this study is to examine the effect of Metabolic Rheostat™ and Butyrate Ultra on blood glucose levels after a liquid meal challenge in patients with prediabetes. In addition, the study also aims to look at the effect of Metabolic Rheostat™ and Butyrate Ultra on weight, HgbA1c, fasting glucose, cholesterol, triglycerides, inflammation markers, and hormones.
Energy Flux and Fat Oxidation Using Low and High Glycaemic Index Foods

The HOMBRE Trial: Comparing Two Innovative Approaches to Reduce Chronic Disease Risk Among Latino...
ObesityMetabolic Syndrome2 moreThe purpose of this study is to test a flexible lifestyle program designed to help Latino men make healthy lifestyle changes to lower their risk of developing diabetes and heart disease. The program is called HOMBRE (Hombres con Opciones para Mejorar el Bienestar y bajar el Riesgo de Enfermedades crónicas; English translation: Men with choices to improve well being and decrease chronic disease risk).
Use of Track Health Function of the MyHealthevet Personal Health Record
Prediabetic StateThis study was a pilot 3-month clinical trial that investigated the feasibility, effectiveness, and acceptability of using the Track Health function of the Veterans Health Administration's patient health record for effecting a more positive physical activity (PA) and dietary intake lifestyle in a sample of 38 overweight and obese Veterans with prediabetes. Baseline and three-month post-intervention outcomes were measured in two main domains: objective (e.g., weight) and subjective (e.g., self-efficacy).
