Probiotics Effect on Glucose and Lipid Metabolism and Gut Microbiota in Patients With Obesity

Study Overview
=================
Brief Summary
-----------------
The purpose of this study is to determine whether the probiotics will be effective in the treatment of obesity

Detailed Description
-----------------
This study aims to evaluate the effect of probiotics on the improvement of glucose and lipid metabolism, as well as the gut microbiota.Baseline, 1 month and 3 months data will be collected and put into analysis to provide some suggestions on the probiotics use in the clinical practice for obesity patients.
