White Tea Fights Obesity

New research published in the journal Nutrition & Metabolism suggests that white tea may be the next obesity fighter because it inhibits the generation of new adipocytes and stimulates fat mobilization from mature fat cells.

Data showed that incubation of preadipocytes with white tea extract solution significantly decreased triglyceride incorporation during adipogenesis in a dose-dependent manner (n = 10) without affecting cell viability (n = 10). The effects were, at least in part, mediated by EGCG (n = 10, 50 muM). White tea extract solution also stimulated lipolytic activity in adipocytes (n = 7). Differentiating preadipocytes cultivated in the presence of 0.5% white tea extract solution showed a decrease in PPARgamma, ADD1/SREBP-1c, C/EBPalpha and C/EBPdelta mRNA levels. Moreover, the expression of the transcription factor ADD1/SREBP-1c was not only decreased on the mRNA but also on the protein level., the researchers wrote.
