Title: Microbiome contribution and metabolite intervention in post-dieting weight regain
Biography: Lenka Dohnalová
Despite the effectiveness of commonly used dietary weight reduction strategies, the majority of dieters fail to maintain the reduced weight in the long run. Recently, we uncovered a contribution of the intestinal microbiome to post-dieting weight regain by flavonoid-mediated regulation of energy expenditure. We identified a stable microbial composition that persists after obesity and promotes faster weight regain after high-fat diet (HFD) re-exposure. Furthermore, we demonstrated that fecal microbiome transplantation as well as flavonoid supplementation ameliorates the secondary weight gain. Additionally, we developed a machine leasing-based algorithm based on 16S rRNA data for the accurate prediction of weight-regain. Our data therefore suggest a possible implication of microbiome and metabolome in the personalized prediction and treatment of post-dieting weight regain.
