Does Green Tea Extract Promote Weight Loss

All teas, such as white, black, green, and oolong are made by processing the leaves or buds of the tea bush (Camellia sinensis) and differ in their degree of processing after harvest. Teas and extracts can support weight loss efforts by providing caffeine and other potentially beneficial factors called catechins. Research supports the notion that caffeine can raise metabolism slightly, which over time could add up to weight loss if an individual consumes a calorie level that does not counterbalance this effect.

Catechins include the highly touted EGCG (epigallocatechin gallate) which in some research has been shown to positively influence some of the events involved in the accumulation of body fat as well as the reduction of existing body fat. Since by and large this research was performed on tissue samples and rodents it is difficult at this time to apply the finding to people.
