Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The mechanisms of obesity are complex, involved in genes, environment, life style, and systemic and adipose tissue inflammation. Dysbiosis of gut microbiome is considered to make a difference in obesity. On the other hand, both long-term and short-term dietary interventions can induce changes in the body composition and structure and function of gut microbiome. However, it is not really clear how gut microbiome changes along with weight loss in overweight or obese.

In the present study, investigators aim to characterize the gut microbiome among overweight or obese participants on a modified Atkins diets. The stool and blood samples were collected by an interval of every 5% and 10% of weight loss, respectively. Data collecting mainly covers: 1) body composition analysis ; 2) obesity related biochemical metabolism; 3) measurement of gut microbiome using metagenome and 16S rRNA sequencing techniques; 4) metabolomics of serum and gut microbiome; 5) measurement of physical activity and diets using questionnaires.
