Green Tea Extract Increases Metabolism, May Aid in Weight ..

There are two ways to lose weight -- either reduce energy intake, or
increase energy expenditure. Because hypothyroidism -- even after
treatment -- may reduce energy expenditure in some people, patients
naturally are looking for options that can help safely help raise the
metabolism.

In a study reported on in the American Journal of Clinical Nutrition,
it was found that green tea extract resulted in a significant increase
in energy expenditure (a measure of metabolism), plus also had a
significant effect on fat oxidation. While some of the effects were
originally theorized to be due to the caffeine content of green tea,
the researchers discovered that the tea actually has properties that
go beyond those that would be explained by the caffeine.

The same amount of caffeine as was in the green tea, administered
alone, failed to change energy expenditure in other studies. This led
reseachers to believe that there is some interaction going on with the
active ingredients of green tea that promotes increased metabolism and
fat oxidation.

The researchers indicated that their findings have substantial
implications for weight control. A 4% overall increase in 24-hour
energy expenditure was attributed to the green tea extract, however,
the research found that the extra expenditure took place during the
daytime. This led them to conclude that, since thermogenesis (the
body's own rate of burning calories) contributes 8-10% of daily energy
expenditure in a typical cubject, that this 4% overall increase in
energy expenditure due to the green tea actually translated to a
35-43% increase in daytime thermogenesis. To learn more, please visit:
