NCT01250106

Brief Summary

The investigators aim to test the hypothesis that Lactobacillus Reuteri-enriched microbiota improves insulin sensitivity and glucose tolerance in obese healthy and obese type 2 diabetes patients by improving gut hormone secretion and compare these findings to healthy lean subjects.
