Drinking 80 milligrams of green tea a day can help in weight loss of 1 pound per month for an average 145 pound woman. Green tea acts as a diuretic and eliminates toxins while increasing metabolism.
Studies show that while weight loss does happen, 20 to 30 kilos is not possible with just green tea itself. The high levels of caffeine and component EGCG present in green tea, help in increasing metabolism and suppressing appetite, which in turn results in weight loss.
