Green tea: the benefits of EGCG on energy expenditure

Green Tea EGCG The popularity of green tea in many parts of the world is not solely due to its taste. Green tea’s exceptional composition means it is also renowned for offering a host of health benefits. Among the components found in green tea are catechins including epigallocatechin gallate or ECGC. Part of the large family of flavonoids, these compounds have been the subject of extensive study, but while EGCG is frequently highlighted for its antioxidant properties, it is less well-known for its effect on energy metabolism. However, according to a meta-analysis published in the Journal of Nutritional Biochemistry1, this molecule may indeed offer beneficial effects for energy expenditure.

Effect of EGCG consumption on energy metabolism

In this review of all published data on EGCG, Japanese researchers examined various parameters such as energy expenditure, lipid oxidation and respiratory quotient. The results of their analysis were conclusive: there is an association between EGCG intake, increased energy expenditure and decreased respiratory quotient. This means that supplementing with EGCG could improve calorie expenditure, and thus reduce total adiposity. Their review confirms that green tea catechins, including EGCG, have a beneficial effect on the body’s energy metabolism.

Potential of EGCG for preventing excess weight and obesity

This new review adds to the many studies published on EGCG, summarised in our article « Epigallocatechin gallate (EGCG), a very powerful antioxidant with multiple benefits». This article mentions EGCG’s potential for increasing energy expenditure and reducing abdominal fat mass. Based on these studies, dietary supplements have been specifically formulated from an extract of green tea standardised to 95% EGCG. This optimal dose provides a simple way of capitalising on all the antioxidant and energy expenditure benefits of EGCG.
