There are 2 pathways to lose weight — either lower energy intake, or increase energy burning. Because hypothyroidism — even after relief — may lower energy production in some people, people normally are looking for healthy options that can support creating a faster metabolism.
In a research study found in the American Journal of Clinical Nutrition, it was demostrated that green tea extract produced a significant ability for greater energy expenditure (a measurement of metabolism), plus also had a significant increasing power on fat burning. While some of the results were originally theorized to be part of the caffeine energy content of green tea, the scienitists found that the tea actually has aspects that go far beyond those that would be offered by caffeine only.
An equal amount of caffeine as was in the green tea, given by itself, failed to produce greater energy expenditure in other research studies. This led scienitists tounderstand that there is some mechanism for which the active herbal ingredients of green tea that enhanced increased metabolic functioning and fat being used as energy.
The scienitists noted that their studies have everyday implications for weight management. A 4% overall increase in 24-hour ability to burn more energy was correlated to the green tea extract, however, the studies found that the extra calorie burning took place during the day. This led them to better understant that, since thermogenesis (the body’s own rate of burning calories) contributes 8-10% of daily energy calorie burning in a typical person, that this 4% overall increase in energy expenditure due to the green tea actually translated to a 35-43% increase in daytime thermogenic functioning.
