Green Tea Applicable Uses:Weight loss.

Green Tea Extract INCI Name Camelia Sinensis Extract EINECS ELINCS No 283-519-7 CAS 84650-60-2 Tea Polyphenols photo picture image Weight loss can be attributed to a reduction in caloric intake or an increase in energy expenditure. Recent studies conducted at the University of Geneva have shown individual treated with Green tea extract showed a 4% increase in energy expenditure as compared to those individuals receiving caffeine or a placebo. Since caffeine alone did not significantly increase the energy expenditure it is hypothesized that the abundance of catechin polyphenols in green tea are responsible for the thermogenic effect. Another study published in 1999 in the American Journal of Clinical Nutrition found that green tea extract may increase energy levels and promote fat oxidation. Since the Green tea extracts did not significantly increase the patients heart rates, Green tea extract could prove to be a safer dietary aide than the current prescription and over the counter stimulants on the market. Dulloo, Abdul G., et al. "Efficacy of a green tea extract rich in catechin polyphenols and caffeine in increasing 24-h energy expenditure and fat oxidation in humans." American Journal of Clinical Nutrition (December 1999):1040-1045.

 The American Journal of Clinical Nutrition conducted a study in which it was found that green tea extract significantly increased energy expenditure (a measure of metabolism), and fat oxidation. The researchers felt that this study had wonderful implications for weight control. The study indicated a nearly 40% increase in daytime thermogenesis. In other words, dieters would burn 40% more fat during the day with Green Tea Extract.

 Weight reduction can be achieved by long-term decreases in energy intake and/or increases in energy expenditure. Several small short-term trials have reported modest 3-4% increases in energy expenditure after the consumption of oolong tea or green tea extract. However, none of these studies were designed to assess weight loss. More recently, a clinical trial in overweight men and women who had lost an average of 7.5% of their body weight by adhering to a very low calorie diet for four weeks found that green tea capsules (573 mg/day of catechins and 104 mg/day of caffeine) were no better than placebo in preventing weight regain over the next eight weeks. At present, there is no evidence from controlled clinical trials that tea or tea extracts promote weight loss or improve weight maintenance in humans. Interestingly, recent studies showed a lowering of tissue fat levels in mice drinking green tea, black tea, or caffeine.

 Tannins are thought to help the body discharge toxins due to pollution and to accelerate the metabolism of fats. A small but interesting 1999 study reported in the American Journal of Clinical Nutrition reported increased energy expenditure and fat oxidation in men who took a green tea extract as opposed to a placebo or caffeine alone.

 Many of the medicinal claims made for green tea haven't been examined outside a laboratory setting, specifically in clinical trials that assess the plant's health effects in people. On the other hand, the pure research findings are exciting and there certainly appears to be no harm in integrating this extract into your daily diet.
