Evaluation of the effect of oral taurine supplementation on levels of fibroblast growth factors, β-Klotho co-receptor, some biochemical indices and body composition in obese women on a weight-loss diet: a study protocol for a double-blind randomized controlled trial

Abstract

Background: according to studies, the function of FGFs are disturbed in obesity. So that, serum level of FGFs are correlated with insulin resistance and obesity. Besides the effects of eicosapentaenoic acid on serum FGF21 concentrations, the effect of other nutrients on FGFs is not clear. Since obesity as an important health problem is rising in the world and on the other side, taurine (Tau) biosynthesis is reduced by adipose tissue-derived factors in obesity, the effects of Tau and a weight loss diet on obesity need to be investigated further. Methods: We will conduct a 2 month’s double-blind, parallel-group, randomized controlled clinical trial to investigate the effect of Tau supplementation on serum levels of fibroblast growth factors, β-Klotho co-receptor, some biochemical indices and body composition in obese women on a weight-loss diet. Discussion: we will determine the other advantages of a weight loss diet on metabolic risk factors. Moreover, for the first time, the effects of a weight loss diet along with Tau supplementation on these variables will be assessed.
