Many studies have shown that green tea has beneficial health effects.
Two new studies have now confirmed that green tea extract can increase fat oxidation and improve insulin sensitivity and glucose tolerance, even in healthy young adults.
In the first study, 12 healthy men performed a 30 minute cycling exercise before and after taking green tea extract. In the second, 11 healthy men took an oral-glucose-tolerance test before and after taking green tea extract. In both cases, their results improved after consuming the tea.
