The Efficacy of Weight-loss Diet Decision-making Based on Initial Gut Metabolic Modules (GMMs)

Sponsor: Taipei Veterans General Hospital, Taiwan

Summary

In recent years, the technology to detect the gut microbiome's function has become increasingly developed. GMMs are tools (GitHub - raeslab/GMMs: A manually curated database of human gut metabolic modules.) for describing metabolic pathways for linking microbial metabolic function to species associated with a single metabolite, helping to analyze the transcriptional characteristics and metabolic functions of each bacterium, and studying their role of the food chain in the ecosystem. According to our previous research, the group with good weight loss response (more than 10% body weight loss in 8 weeks) after low-carb diet intervention has higher Shannon's diversity and carbohydrate degradation activity test by GMMs, implying the deficiency of availability of energy sources may cause more weight changes. Based on the above research, we designed a low-carb diet (rich in monounsaturated fatty acids) and a low-fat diet (whole grains) with the same calories as a means of weight loss. The primary purpose of this study is to evaluate the pre-GMM test for determines the weight loss benefit of the intervention diet. Furthermore, we try to found the possible mechanism of whether metabolites of microbiota (e.g. SCFA) could affect the immune cell change which modulates adipose tissue .
