Biobank of Blood Samples from Overweight or Obese Patients

Condition: Healthy Volunteers
Investigator: Joshua Cook, MD, PhD
Status: Currently Recruiting
We are seeking adult volunteers with body mass index in the obesity range (30-45 kg/m2) to come in for a single study visit where they answer some health questions and have a small volume of blood drawn (25 cc/1.7 tbsp). We will measure levels of the blood sugar-lowering hormone insulin as well as glucose (sugar), certain fats…

Temporary Insulin Resistance

Condition: Healthy Volunteers
Investigator: Joshua Cook, MD, PhD
Status: Currently Recruiting
We are recruiting volunteers, aged 18-70, for a research study on the buildup of excessive liver fat ("fatty liver disease") in people with or at risk for type 2 diabetes because their bodies are resistant to the actions of the blood sugar-lowering hormone, insulin. To do this, we seek to temporarily induce or accentuate insulin resistance in 14 volunteers…

Effect of lowering insulin levels on blood sugar

Condition: Healthy Volunteers
Investigator: Joshua Cook, MD, PhD
Status: Currently Recruiting
We are conducting a research study on how insulin controls blood sugar in both healthy people and those at risk of type 2 diabetes. We are seeking adult volunteers, aged 18-65, who have body mass indices either in the lean range (18-25 kg/m2) or in the obesity range (30-45 kg/m2) but who do not have prediabetes or diabetes.…

Lowering Insulin Levels in Fatty Liver Disease

Condition: Healthy Volunteers
Investigator: Joshua Cook, MD, PhD
Status: Currently Recruiting
We are conducting a research study on the effect of high insulin levels on the buildup of excessive liver fat ("fatty liver disease") in people at risk for type 2 diabetes. We are seeking adult volunteers, aged 18-70, who are overweight or obese with a body mass index of 27-50, and have been diagnosed with, or are at risk for, prediabetes.…

Changes in Brain Biomarkers After Bariatric Surgery or Low-Calorie Diet (ages 18-65)

Condition: Healthy Volunteers
Investigator: Sharon Wardlaw, MD
Status: Currently Recruiting
The goal of this project is to understand why bariatric surgery is such an effective treatment for obesity with a focus on brain mechanisms. Cerebrospinal fluid neuropeptides, hormones, and protein levels will be measured in subjects before and after bariatric surgery as compared with subjects before and after diet-induced…
