Green tea extract

The ability of green tea extract to help people lose weight has been demonstrated, in addition to its many other wonderful health advantages. Caffeine and catechins, two substances found in green tea, help the beverage to aid in weight loss. A well-known stimulant that boosts fat burning and reduces hunger is caffeine. Epigallocatechin gallate (EGCG), in particular, has been found to increase metabolism and decrease fat.

Green tea extract contains both EGCG and caffeine, which together increase the body's capacity to burn calories and promote weight reduction. In fact, a study of 10 healthy individuals found that ingesting EGCG and caffeine together increased calorie burn by 4%. The ability of green tea extract to decrease hunger in humans has not been studied, however, it appears that green tea combined with other compounds may do so. Up to 800 mg of EGCG in green tea has been determined to be safe. 1,200 mg of EGCG at higher levels has been connected to nausea.
