The goal of this study is to investigate comparisons between the intestinal microbiome in patients with obesity and in patients with obesity and Non-Alcoholic Fatty Liver Disease (NAFLD). With this protocol we hope to better understand how the microbiome of each individual works with disease progression.

Other: Blood Draw
2 tablespoons of blood will be drawn from participants at study entry, 3 months after study entry, and 6 months after study entry.
Other: Stool collection
Stool will be collected from participants 3 times during the study -- at study entry, 3 months from study entry, and 6 months after study entry.
Other: BodPod Measurement
Body composition will be measured using a BodPod at study entry, 3 months after study entry, and 6 months after study entry.
Other: Liver Ultrasound
A liver ultrasound will be performed at study entry and 6 months after study entry.

The goal of this study is to investigate and compare the composition of the intestinal microbiome in patients with obesity only to patients with obesity and Non-Alcoholic Fatty Liver Disease (NAFLD). In addition, we will investigate the relationship between alterations in the intestinal microbiome, immune activation, and the progression of NAFLD to Non-Alcoholic Steatohepatitis (NASH). We hypothesize that alterations in the intestinal microbiome are associated with increased immune activation and progression of obesity associated NAFLD. Based on this hypothesis we propose the following aims:
Aim 1. Identify and enroll pediatric cohort with obesity or obesity/NAFLD to study the role of the intestinal microbiome on the development of NAFLD.
Aim 2. Characterize the intestinal microbiome through quantitative PCR and high throughput sequencing analysis of stool specimens in participants with obesity and obesity/NAFLD.
Aim 3. Characterize evidence of systemic inflammation by C-reactive protein (CRP), Tumor necrosis factor alpha (TNF-alpha)Transforming growth factor beta 1 (TGF-beta and LPS Binding Protein (LBP) levels, and analyze results in relationship to the intestinal microbiome and the presence of NAFLD.
