Functional aspects of green tea catechins in the cellular metabolism and their relationship with body fat reduction

The use of tea is widespread, second only to water in worldwide consumption. Green tea is rich in polyphenols, mainly catechins. Among a variety of beneficial health effects attributed to the consumption of the green tea, much attention has been given to its ability to reduce body fat. This study has the objective of presenting a description of the studies of green tea and/or its bioactive compounds related to cell biology and of experimental and epidemiological studies associated with lipid metabolism and the reduction of body fat. Epigallocatechin gallate is the main bioactive compound present in green tea and its anti-obesity effects are being investigated. Such effects are associated with several biochemical and physiological mechanisms and among them the following stands out: stimulation of lipid metabolism by combining catechin intake with regular physical activity. In spite of the promising effect of green tea and its bioactive compounds on the treatment of obesity, there is a need for controlled clinical trials. Finally, a proper diet associated with regular physical activity is the key to prevent obesity and its comorbidities.
