The big buzz concerning green tea (Camellia Sinensis) is usually on account of the catechins (Epigallocatechin gallate)(EGCG) that it contains and their benefit on weight loss.(4) When combined with caffeine, green tea is highly synergistic.(5) In fact when combined with caffeine, the effects of green tea on fat loss doubled. This was shown in a 2009 study by “The Journal of Nutrition”. Noradrenaline a Catecholamine, is destroyed in the body by an enzyme known as Catechol-o-Methyltransferase (COMT). Epigallocatechin gallate in green tea has been shown to positively affect the release of (COMT).(6) By preserving the amount of noradrenaline in the body, the cAMP rate increase through activation of adenylate cyclase. Further on enhancing the activation of protein kinase A leading to lipolysis (the breakdown of lipids)(7)(8) Naturally occurring caffeine levels in tea extracts can range from 4.8-9.3 percent.(9)
