Your DNA makeup highly influences your fat loss and metabolism response to green tea, a fact demonstrated by the world-leading DNA testing company for fat loss : AnabolicGenes.com
Green tea is much more than just green liquid that you drink. In fact, it is thought to be one of the healthiest hot drink in the world. It is full of nutrients and antioxidants. That’s why the effects of green tea on the body and metabolism are powerful. This includes improved fat loss, brain function, increased metabolic rate, and many other benefits.
Many of the bio-active compounds in the tea leaves do make it into the final drink, which contains very high amount of important micro-nutrients. It is loaded with polyphenols like catechins & flavonoids, which both function as extremely powerful antioxidants. These compounds have the power to reduce the formation of free radicals in the body, allowing them to protect the cells and molecules from damage. They are also known to play a role in aging, metabolism and all sorts of diseases. One of the more powerful compound in green tea is the antioxidant EGCG (Epigallocatechin Gallate). It has been studied to treat numerous diseases and it is the main reason green tea has powerful medicinal properties.
How genetics influence your effects of green tea when it comes to fat loss and increase your metabolism?
The COMT gene encodes an enzyme called ‘catechol-O-methyltransferase’ that is highly involved in breaking down the neurotransmitter Dopamine but also Adrenaline (also called epinephine), and Noradrenaline (also called norepinephrine). Both adrenaline & noradrenaline are the master fat loss hormones. The enzyme adds a methyl group (from SAMe, also called s-adenosylmethionine) to the neurotransmitter dopamine, adrenaline, and noradrenaline, thus changing them into a different substance.
Alright, now what is the link between COMT and the effects of green tea? Green tea is able to increase fat oxidation (fat burning) and energy expenditure (increased metabolism) by inhibiting the COMT gene by catechins, especially the famous catechin EGCG. Nevertheless, it does constantly seem animously because of substantial inter-individual variability. This variability might be described by distinct genotypes in the COMT gene polymorphism that are associated with COMT protein activity.
A 2014 study1 looked at the differences in energy expenditure (metabolic rate) and fat oxidation with green tea based on COMT genotype. People with the GG genotype of the Val159Met polymorphism of the COMT gene had significantly increased energy expenditure (metabolism) and fat burning effects with green tea, while those with the AA genotype had no increase. Therefore, having a G allele or two G alleles in your COMT gene would highly benefit from the effects of green tea when it comes to fat loss and increased metabolism.

Conclusion: Are you wasting your time and money trying to loose some fat by drinking lot of green tea ?
