Green Tea Extract Increases Metabolism,
May Aid in Weight Loss
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.
n 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 researchers 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 percent 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 to 10 percent of daily energy
expenditure in a typical subject, that this 4 percent overall increase in energy
expenditure due to the green tea actually translated
to a 35-43 percent increase in daytime thermogenesis.
