Green Tea, High in Epigallocatechin Gallate (EGCG) and Postprandial Fat Oxidation

The body of evidence regarding the health benefits of green tea has grown considerably during the last decade and includes antioxidant properties, anti- cancer, anti-obesity and anti-diabetes effects. There has been evidence that green tea extract favorably affect body weight and body fat and has positive effects on blood glucose control

Aim of this study is to investigate the short term effect (3-day)of TEAVIGO (high in the catechin EGCG) on postprandial fat oxidation during different phases of the postprandial period in overweight subjects. Secondly, in a subset of volunteers changes in lipolysis and glucose metabolism will be studied in skeletal muscle and adipose tissue.
