The decrease in body fat was apparently the result of the body’s stimulation by substances called catechins found in the green tree extract; these catechins served as triggers for calorie-burning and are contained in green tea diet pills. With green tea fat burner pills, the typical dosage would be between 100 and 750 mg daily (that’s two or three capsules). As with other kinds of food and beverage, allergic reactions may be possible when taking green tea extract in pill form.

A low dose of epigallocatechin gallate (EGCG) from green tea was found to increase fat oxidation by 33 per cent, according to findings published in the European Journal of Clinical Nutrition. “This pilot study provides for the first time evidence that a single green tea catechin, EGCG, can increase fat oxidation in obese men, at least within 2 h after meal intake. Within this postprandial phase, EGCG is equipotent with caffeine with regard to fat oxidation,” wrote the authors, led by Frank Thielecke from DSM Nutritional Products. Green tea has been studied extensively for its potential in the weight management category, with the compound epigallocatechin gallate (EGCG) highlighted as a key component. A daily dose of 300 mg of EGCG was associated with a 33 per cent increase in fat oxidation, while a daily dose of 200 mg caffeine was linked to a 34.5 per cent increase. When male subjects were given a combination of EGCG (300 mg) and caffeine (200 mg), fat oxidation increased by almost 50 per cent, added the researchers. The EGCG used in the study was DSM's Teavigo ingredient, with 94 per cent EGCG purity. Results showed that during two hours after a meal, the low-dose EGCG supplementation was associated with a 33 per cent increase in fat oxidation. The high-dose EGCG supplementation produced a non-significant 20 per cent increase, compared to placebo. Caffeine alone was associated with a 34.5 per cent increase, compared with placebo, while the combined EGCG/ /caffeine supplement boosted fat oxidation by 49 per cent. “There is no synergism of low EGCG and 200 mg caffeine,” stated the researchers. The results obtained for the combination of EGCG and caffeine may be related to the amount of time the compounds remain in the blood, with the so-called half-life of EGCG reprted to be about two hours while caffeine has a half-life of about four hours. “Therefore, EGCG affects obviously the early, whereas caffeine affects both early and late postprandial fat oxidation,” added Thielecke and his co-workers. A recent review from researchers at Pennsylvania State University concluded that the science supporting the weight management potential of green tea and its extracts was (Journal of Nutrition, doi: 10.3945/jn.109.115972).

Results: Relative to placebo, treatment with the green tea extract resulted in a significant increase in 24-h EE (4%; P < 0.01) and a significant decrease in 24-h RQ (from 0.88 to 0.85; P < 0.001) without any change in urinary nitrogen. Twenty-four–hour urinary norepinephrine excretion was higher during treatment with the green tea extract than with the placebo (40%, P < 0.05). Treatment with caffeine in amounts equivalent to those found in the green tea extract had no effect on EE and RQ nor on urinary nitrogen or catecholamines. Consequently, ingestion of capsules containing the green tea extract AR 25 provided daily a total of 150 mg caffeine and 375 mg catechins, of which 270 mg was epigallocatechin gallate. The oxidation rates of protein, carbohydrate, and fat were calculated from 24-h EE, RQ, and urinary nitrogen excretion for each 24-h stay in the respiratory chamber ( 17 ). Diurnal EE was higher during treatment with the green tea extract than during treatment with placebo or caffeine, by 4.5% and 3.2%, respectively, but significantly so only for the green tea extract. Total 24-h EE with the green tea extract, however, was significantly higher than that with both the placebo and caffeine, by 3.5% and 2.8%, respectively. Furthermore, despite the absence of differences in urinary nitrogen excretion, and hence in protein oxidation rates, the observed reductions in RQ during treatment with the green tea extract suggest that fat oxidation was higher and carbohydrate oxidation was lower during this period than during the placebo period. Indeed, calculations of the relative contribution of substrate oxidation to daily EE indicated that the contribution of fat oxidation to 24-h EE, which was 31.6% with the placebo, was higher (41.5%) with the green tea extract. Of particular interest in this study was that the effects of the green tea extract in enhancing thermogenesis and fat oxidation could not be explained solely on the basis of its caffeine content because treatment with an amount of caffeine equivalent to that in the extract failed to alter EE, RQ, or substrate oxidation.

Green tea extract. History of tea extracts[ edit ] Green tea extracts have been used in traditional Chinese and Indian medicine for a variety of uses. Types of green tea extracts[ edit ] The cardinal antioxidative ingredient in the green tea extract is green tea catechins (GTC), which comprise four major epicatechin derivatives; namely, epicatechin (EC), epigallocatechin (EGC), epicatechin gallate (ECG), and epigallocatechin gallate (EGCG).  A remarkably higher content of myricetin is detected in tea and its extracts than in many other plants, and this high concentration of myricetin may have some implications with the bioactivity of tea and its extracts. Caffeine may be excluded in green tea extracts in order to avoid side-effects; caffeine-free green tea extract supplements are now available. The stability in alkaline solutions varies between four components of GTC in green tea extracts. The biochemical properties of green tea extracts can be generally divided into four aspects – antioxidant , anticarcinogen , anti-inflammatory , and anti-radiation.  Generally speaking, green tea extracts are more effective as antioxidants than black tea extracts are due to the better preservation of catechins contained in green tea extracts. Moreover, the anticarcinogenic properties of green tea extracts have been a focus of recent scientific research. In many experiments, green tea extracts show inhibitory effects on cancer cells.  The bactericidal activity against S.mutans is conspicuous in Japanese green tea extracts,  and the maltose level in mouth is consistently lower after drinking tea.  Therefore, green tea extracts may be effective in oral hygiene maintenance. Green tea extract supplements are accessible over the counter in various forms.
High Dosage of EGCG for Weight Loss. Now that modern science has uncovered the various antioxidants and other beneficial compounds in green tea, it has risen from the rank of beverage to nutraceutical, with its effects on weight loss hogging the spotlight. The catch is that the dose needs to be high, and preferably not oral. Numerous health effects have been attributed to EGCG, including weight loss - but the research was conducted with such high concentrations of EGCG that you are unlikely to get enough from drinking green tea alone. Research has shown that EGCG may help increase calorie burn and help the body use stored fat for energy, although the exact mechanism is unclear. The catch is that the rats were given an injection of EGCG, and the results were not as promising when the EGCG was given orally. It is unclear whether the body may not absorb EGCG fully from the digestive tract, but if an oral extract didn't work, that leaves little hope for the lower concentrations provided by oral tea consumption. There is no established dose for EGCG, partly because the research has been all over the map. Ronald Hoffman mentions a French study that found results using 90 mg of EGCG three times daily, while a 2007 study in the "Journal of the American College of Nutrition" found that twice-daily doses of 150 mg reduced resting heart rate and blood glucose levels, but did not affect weight loss. Because EGCG is but a small part of the overall polyphenol content, you're more likely to get a high enough dose by using an extract. The most successful research into EGCG and weight loss has used injections rather than oral administration. Long-term oral use may mimic the results of an injection, which means that EGCG is not a quick fix - results may take time, and the EGCG supplement must be a part of an overall diet and exercise program.

The combination of diabetic medication and green tea produced a statistically significant reduction in hemoglobin A 1 C. Consumption of 576 mg green tea catechins per day for 24 weeks in obese children6 found that those who were the most obese had a statistically significant reduction in waist circumference, blood pressure, and LDL cholesterol. Studies with fat cells show that green tea catechins turn on gene signals that produce adiponectin10 . Another study shows that green tea prevents the accumulation of fat12 inside fat cells. A recent animal study showed that green tea decreased total cholesterol, LDL cholesterol, and triglycerides while also lowering the levels of leptin14 in the blood. In another transgenic mouse, this one programmed to die more quickly, it was found that green tea in combination with exercise16 extended the mouse’s health and life. The green tea enabled better use of oxygen by muscles, improved antioxidant function within muscles, and increased the rate of fat burning by muscles.

In the current study , published in Obesity, obese mice that were fed a weight-gaining diet put on significantly less weight when they were supplemented with green tea extract. In addition to this Vegas buffet of mice chow, one group of mice were fed EGCG (epigallocatechin-3-gallate), the polyphenol in green tea that has been found to have the most profound effect on metabolism and weight. The group getting the EGCG supplement gained weight at about 45% the rate of the non-supplemented mice. “The mice are essentially eating a milkshake, except one group is eating a milkshake with green tea”. Lambert estimates that a person would need to drink ten cups of green tea each day to match the amount of EGCG used in the study. One single capsule of EGCG (green tea extract (EGCG) provides 250 mg, the amount you’d get from 10 cups providing 25 mg each, or approximately 6 cups providing 40 each. The researchers in this study also noted that fecal fat excretion was 30% higher in the EGCG mice.
