Mechanism of Microbiome-induced Insulin Resistance in Humans (Aim 1)

Completed · Phase 2 · Has a placebo group

Conditions studied: Insulin Sensitivity

In brief

The purpose of this study is to determine insulin sensitivity in individuals that are lean normal glucose tolerant subjects after consumption of a normal low fat diet and after a high fat diet and to explore the effects of high fat consumption on the intestinal microbiome, and metabolic endotoxemia.( Aim 1 of the protocol, a separate record is available for Aim 2)
