Green tea's metabolism boosting effect is achieved by the inhibiting action of its most active ingredient epigallocatechin gallate (EGCG) on the activity of the enzymes that breakdown the neurotransmitter known as norepinephrine making it last longer. The effect of norepinephrine increases the process of thermogenesis - the generation of immense heat in the body. Thermogenesis is mainly considered to increase the body's energy expenditure as well as having a significant effect on body fat oxidation.Green tea has the ability to speed up the body's metabolic rate by up to 4%. This seemingly insignificant boost in metabolism can however with little or no effort than just drinking 2-4 cups daily help to burn stored body fats and reduce fat storage. Over time, this 4% boost in calorie burning can substantially increase an individual's overall fat burning capability.
