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
