Green tea induces weight loss and helps in the treatment of obesity and its comorbities
Abstract
Introduction: Obesity has been increasing in an exponencial manner. It is expected that by the year 2015, 700 million people will be obese. This pathology seems to be one of the main causes of many, not contagious, chronic diseases, increasing the chances of developing some even lethal illnesses like dislipidemias, heart diseases and diabetes. Objective: To make a bibliographical revision about the capacity of green tea in helping the treatment and prevention of obesity, as well as its comorbities. Literature Review: It’s been shown, in models of cells, animals and humans, that the green tea, its catechins and epigallocatechin gallate (EGCG) are able to promote decrease in body weight and body fat and help in the prevention and treatment of obesity and associated diseases such as diabetes, heart deaseases and dislipidemy. The main forms of action would be the increase of fat oxidation and energy expenditure and the decrease of fat absorption and glucose, decrease of the levels of triacylglycerol, total cholesterol and low-density lipoprotein oxidation. Conclusion: Green Tea and its components are effective in the treatment of obesity, as well as in helping its prevention and treatment of its comorbities.
